Disclosure of Invention

Problems to be solved by the invention

Recently, however, it has been required not only to form a pattern on a warp knitted fabric produced by a double raschel machine, but also to provide unevenness in accordance with the pattern. For example, recently, a manufacturing method using warp knitting, which has high manufacturing efficiency, has been attracting attention as a manufacturing method of an upper. Further, it is required to form not only a pattern on the upper but also an unevenness in conformity with the pattern.

However, in the warp knit fabric produced by the conventionally known double raschel machine, the surface is almost flat. For example, although some irregularities recognizable by touch can be formed in conformity with the pattern by making the yarn fed to the jacquard bar thicker than the other yarns, sufficiently large irregularities to be recognizable at a glance cannot be formed in conformity with the pattern.

In addition, quilted products have been known as a fabric having irregularities. However, the method for manufacturing the quilted product is a method of manufacturing the surface fabric and the back fabric separately, and then sandwiching the core material between the surface fabric and the back fabric, and finally sewing, and the method is complicated. The manufacturing process is more complicated if holes are to be provided in the quilted product.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a warp knitting machine capable of forming unevenness in accordance with a pattern on a warp knitted fabric, a method for producing a warp knitted fabric having unevenness in accordance with a pattern, and an upper having unevenness in accordance with a pattern.

Detailed Description

The present embodiment will be described with reference to the drawings. The present embodiment is merely an example, and appropriate modifications made without departing from the scope of the invention are also included in the scope of the invention.

1. Embodiment mode 1

(1) Structure of warp knitting machine

The warp knitting machine according to embodiment 1 is a double raschel machine including a front side needle row FN and a rear side needle row BN, knitting a front side base fabric 1 with the front side needle row FN, knitting a rear side base fabric 2 with the rear side needle row BN, and further connecting the front side base fabric 1 and the rear side base fabric 2 at least at a part of these base fabrics. The front side needle knitting array FN and the rear side needle knitting array BN respectively arrange a plurality of knitting needles in a row along the width direction of the double Raschel machine. The gauge is 24E (24 needles per 1 inch), for example.

As shown in fig. 1, the double raschel machine according to embodiment 1 is a so-called double-jacquard double raschel machine including a front pair of jacquard bars JB3 and JB4 (hereinafter referred to as "front jacquard bars JB3 and JB 4") and a rear pair of jacquard bars JB6 and JB7 (hereinafter referred to as "rear jacquard bars JB6 and JB 7").

The jacquard bars JB3, JB4, JB6 and JB7 perform the basic motions used to knit the basic organization, respectively. Subsequently, a plurality of jacquard guides (japanese: ジャカードガイド) provided on jacquard guide bars JB3, JB4, JB6, and JB7, respectively, perform a basic motion for knitting a basic tissue.

These jacquard guides can be displaced independently on the basis of the action of the respective jacquard mechanism, in addition to the basic movement for knitting the basic tissue. For this purpose, the jacquard guides can perform different movements. When the jacquard mechanism is active, the jacquard guide is displaced by a distance of 1G (distance between adjacent 2 needles) from the position in the knitting of the basic tissue. The direction of displacement is such that the jacquard guide of the front jacquard bars JB3, JB4 is to the left and the jacquard guide of the rear jacquard bars JB6, JB7 is to the right. The jacquard mechanism may be operated only for the front lapping, only for the back lapping (japanese: アンダーラップ), or both of the front lapping and the back lapping.

The double raschel machine according to embodiment 1 includes at least 1 guide bar on the front side of the front jacquard bars JB3 and JB4, and at least 1 guide bar on the rear side of the rear jacquard bars JB6 and JB 7.

In fig. 1, 2 guide bars GB1 and GB2 are provided as guide bars on the front side of the front pattern bars JB3 and JB4, and 2 guide bars GB8 and GB9 are provided as guide bars on the rear side of the rear pattern bars JB6 and JB 7. However, in knitting the warp knitted fabric 10, at least 1 of the 2 guide bars GB1 and GB2 on the front side is used, and it is not necessary to use 2 guide bars. In knitting of the warp knitted fabric 10, at least 1 of the rear 2 guide bars GB8 and GB9 may be used, and 2 guide bars need not be used.

Further, the double raschel machine of embodiment 1 includes at least 1 guide bar between the front jacquard bars JB3, JB4 and the rear jacquard bars JB6, JB 7. In fig. 1, as such guide bars, 1 guide bar GB5 is provided.

The guide bars GB1, GB2, GB5, GB8, GB9 each perform the basic movements used to knit the knit structure. The guides respectively provided on the guide bars GB1, GB2, GB5, GB8, GB9, unlike the jacquard guide, cannot perform different movements from the other guides provided on the same guide bar.

In each guide bar GB1, GB2, GB5, GB8, GB9, the number of guides per 1 inch is the same as the number of needles per 1 inch. Further, in the guide bars GB1, GB2, GB5, GB8, and GB9, the guides are disposed at positions corresponding to the knitting needles.

On the other hand, jacquard guide bars JB3, JB4, JB6, and JB7 are half-size jacquard guide bars, respectively. Further, by making the 2 jacquard guide bars a pair, the pair is made a full size as a whole. That is, in each of the jacquard guide bars JB3, JB4, JB6, and JB7, the number of jacquard guides per 1 inch is half of the number of knitting needles per 1 inch, and 1 jacquard guide is arranged per 2 knitting needles. Here, the positions of the jacquard guides are shifted by 1 needle between the 2 jacquard guide bars forming a pair. By making the 2 jacquard guide bars a pair, the number of knitting needles and the same number of jacquard guides are provided, and each guide is arranged at a position corresponding to each knitting needle.

Therefore, by making the jacquard guide bars JB3 and JB4 a pair, the same number of jacquard guides as the number of knitting needles are provided, and these jacquard guides are arranged at positions corresponding to the respective knitting needles. By making the jacquard guide bars JB6 and JB7 a pair, the same number of jacquard guides as the number of knitting needles are provided, and these jacquard guides are arranged at positions corresponding to the knitting needles.

In the above guide bar arrangement, front padding can be performed to the front side needle row FN from the guide bar GB1 to the back jacquard bars JB6, JB7, and front padding can be performed to the back side needle row BN from the front jacquard bars JB3, JB4 to the guide bar GB 9.

The warp knitting machine according to embodiment 1 has the same structure as a known double raschel machine except for the above structure.

(2) Method for manufacturing warp knitting fabric 10

In the double raschel machine having the above structure, the front base fabric 1 is knitted by at least 1 of the guide bars GB1 and GB2 located on the front side of the front guide bars JB3 and JB 4. Further, the rear side group fabric 2 is knitted by at least 1 of guide bars GB8, GB9 on the rear side of the rear jacquard guide bars JB6, JB 7.

In parallel with the knitting of the front base fabric 1 and the back base fabric 2, the jacquard mechanisms of the front jacquard guide bars JB3, JB4 and the back jacquard guide bars JB6, JB7 are operated, respectively, whereby the jacquard yarn supplied from the front jacquard guide bars JB3, JB4 (hereinafter referred to as "front jacquard yarn") and the jacquard yarn supplied from the back jacquard guide bars JB6, JB7 (hereinafter referred to as "back jacquard yarn") are knitted into the front base fabric 1 and the back base fabric 2. The jacquard yarns woven into the front base fabric 1 and the rear base fabric 2 are exposed on the surfaces of these base fabrics to form a jacquard pattern.

The jacquard pattern is a pattern formed of a jacquard yarn exposed on the surface of the warp knitted fabric 10.

In parallel with the formation of the jacquard pattern, the jacquard mechanisms of the front jacquard guide bars JB3, JB4 and the back jacquard guide bars JB6, JB7 are operated, respectively, whereby the front jacquard yarn and the back jacquard yarn connect the front base fabric 1 and the back base fabric 2 to at least a part of the warp knitted fabric 10.

Here, since the connecting position at which the front base fabric 1 and the rear base fabric 2 are connected and the position (non-connecting position) other than the connecting position are formed by the jacquard yarn, they correspond to the constituent elements of the jacquard pattern exposed on the surface of the warp knitted fabric 10. For example, when the front jacquard yarn is knitted into the rear base fabric 2 and the rear jacquard yarn is knitted into the front base fabric 1 to form the above-described connecting portion, the rear jacquard yarn is exposed on the surface of the front base fabric 1, and becomes a component of the jacquard pattern on the surface of the front side of the warp knitted fabric 10.

Preferably, the connection position and the non-connection position are located over a plurality of courses and a plurality of wales, respectively.

Further, in parallel with the formation of the jacquard pattern and the like, the guide bar GB5 between the front pattern bars JB3, JB4 and the rear pattern bars JB6, JB7 inserts the insert yarn between the front base fabric 1 and the rear base fabric 2. The insert yarn inserted by the guide bar GB5 is pressed and compressed by the front base fabric 1 and the rear base fabric 2 at the connecting position of the front base fabric 1 and the rear base fabric 2. On the other hand, the insert yarn inserted by the guide bar GB5 is not pressed by the front base fabric 1 and the rear base fabric 2 and is not compressed at the non-connecting position of the front base fabric 1 and the rear base fabric 2. Therefore, the portion constituted by the non-connected position bulges out from the portion constituted by the connected position.

As a result of knitting as described above, on the surface of the warp knitted fabric 10, the portion constituted by the connected position becomes a concave portion, and the portion constituted by the non-connected position bulges out to become a convex portion. Since the connected position and the disconnected position are related to the jacquard pattern exposed on the surface of the warp knitted fabric 10, the warp knitted fabric 10 is formed with the unevenness corresponding to the jacquard pattern.

As 1 preferred embodiment, a stitch is formed on the front base fabric 1 by the front guide bar GB1 or GB2, and a stitch is formed on the rear base fabric 2 by the rear guide bar GB8 or GB 9. Further, by the operation of the jacquard mechanism, a position where the front jacquard yarn and the rear jacquard yarn connect the wales adjacent to the pillar stitch and a position where the front jacquard yarn and the rear jacquard yarn do not connect are formed in the front base fabric 1 and the rear base fabric 2, respectively. Further, when the position where the adjacent wales in the front side group fabric 1 are not connected and the position where the adjacent wales in the rear side group fabric 2 are not connected are made to coincide in the front-rear direction (the direction perpendicular to the surface of the warp knitted fabric 10, i.e., the front-back direction of the warp knitted fabric 10), a hole penetrating the warp knitted fabric 10 is formed at the position.

(3) Specific formulation example 1

An example of knitting the warp knitted fabric 10 as described above will be described. The warp knit fabric 10 in this example is used for an upper, for example.

The knitting structure of this example is shown in FIG. 2. In each knitting structure diagram, F denotes a course knitted with the front side needle row FN, and B denotes a course knitted with the rear side needle row BN. In embodiment 1, guide bars GB2, GB5, GB8, GB9, and jacquard bars JB3, JB4, JB6, JB7 are used for knitting.

In this knitting, yarns are fed to guide bars GB2, GB5, GB8 and GB9, respectively, and the yarn is fully threaded (Japanese: フルセット). That is, yarns are fed to all guides by the guide bars GB2, GB5, GB8, and GB 9. Thus, the same number of yarns as the number of knitting needles of 1 knitting needle row are supplied to the guide bars GB2, GB5, GB8, and GB 9.

Also, the front and rear jacquard guide bars JB3, JB4, JB6, JB7, respectively, are also fed and fully penetrated. That is, in each of the jacquard guide bars JB3, JB4, JB6, and JB7, yarns are supplied to all the jacquard guides. Thus, the same number of yarns as the number of knitting needles of 1 knitting needle row are supplied to the entire front guide bars JB3 and JB 4. Also, the same number of yarns as the number of knitting needles of 1 knitting needle row is supplied to the entire back jacquard guide bars JB6 and JB 7.

As shown in FIG. 2(a), the knitting structure of the guide bar GB2 is a pillar stitch in which stitches are formed by the same wales, and is constituted by a repeating unit of 0-1/1-1/1-0/0-0// or more.

In addition, in this description, the odd numbers (0-1 and 1-0 in the above example) indicate the effect on the needles of the front needle row FN, and the even numbers (1-1 and 0-0 in the above example) indicate the effect on the needles of the rear needle row BN.

The knitting structure of the guide bar GB5 shown in FIG. 2(c) is an insertion structure and is composed of a repeating unit of 0-0/1-1/1-1/0-0// c. The knitting structure of the guide bar GB8 shown in FIG. 2(e) is a pillar stitch and is composed of a repeating unit of 1-1/1-0/0-0/0-1// or more. The knitting structure of the guide bar GB9 shown in FIG. 2(f) is an insertion structure comprising 1-1/0-0/0-0/1-1// repeating units.

In this way, the guide bars GB2 and GB8 form a stitch from all the wales and courses of the front base fabric 1 and the rear base fabric 2. Here, since the knitting structure by the guide bar GB2 and the guide bar GB8 is a chain structure, adjacent wales are not connected to each other without a jacquard yarn. As described later, the jacquard yarn connects adjacent wales to each other.

The inserted yarn inserted by the guide bar GB5 plays a role of expanding the warp knitted fabric 10 as described later. Also, the insert yarn inserted by the guide bar GB9 plays a role of reinforcing the warp knit fabric 10.

Fig. 2 also shows the basic weave formed by the jacquard bars JB3, JB4, JB6, JB7, i.e. the knitting weave formed by the jacquard bars JB3, JB4, JB6, JB7 when the jacquard weave is inactive. The basic structure based on the pre-guide bars JB3 and JB4 shown in FIG. 2(b) is composed of 1-0/1-2/1-2/1-0// repeating units. The basic organization formed by the back jacquard guide bars JB6 and JB7 shown in FIG. 2(d) is composed of 1-0/1-2/1-2/1-0// repeating unit.

In fig. 3, the basic structure formed by the front pattern bars JB3 and JB4 is shown by broken lines, and the knitting structure formed by the front pattern bars JB3 and JB4 is shown by solid lines when the jacquard mechanism is operated.

In each knitting structure diagram, H in the drawing indicates that the jacquard mechanism is deactivated. In this case, the jacquard guide is located in the same position as when the basic weave is knitted. And T in the figure indicates that the jacquard mechanism is activated. In this case, the jacquard guide is displaced from the position where the basic weave is knitted. T and H are described in the upper and lower stages of 1 knitting needle position, however, T or H in the upper stage indicates that the jacquard mechanism is activated or deactivated when the yarn is laid in front of the needle, and T or H in the lower stage indicates that the jacquard mechanism is activated or deactivated when the yarn is laid in back of the needle.

Fig. 3(a) and (b) show an example of knitting structure in the case where the front guide bars JB3 and JB4 are subjected to inlay knitting with respect to the front knitting needle row FN by the operation of the jacquard mechanism. The braided structure of FIG. 3(a) is 1 in the structure called a texture of pachynsis, and is composed of 1-0/2-2/2-3/1-1// repeating unit. The braided structure of FIG. 3(b) is 1 of the structures called parenchymal structures, and is composed of 1-0/2-2/1-2/1-1// repeating units.

In this way, the front base fabric 1 is formed of the front jacquard yarns and the yarns supplied from the guide bar GB2 by the front jacquard guide bars JB3, JB4 performing the needle front lapping with respect to the front knitting needle row FN. At this time, the front jacquard yarn is exposed on the surface of the front base fabric 1 (the surface of the front side of the warp knit fabric 10).

Here, the front effect yarn reciprocates in the wale direction (weft direction) by 3 pitches in 1 repeating unit while forming a needle loop in the case of knitting a thick texture in fig. 3(a), and reciprocates by 2 pitches in the wale direction in 1 repeating unit while forming a needle loop in the case of knitting a thin texture in fig. 3 (b). For this purpose, the front yarn connects different wales of the knit stitch formed by the yarn supplied from the guide bar GB2 to each other. In addition, the thick weave of fig. 3(a) has a larger bar shog width in the wale direction (weft direction) than the thin woven weave of fig. 3(b), and the front base fabric 1 is thickened accordingly.

Fig. 3(c) shows an example of a knitting structure in the case where the front guide bars JB3 and JB4 are laid only in the same wale by the operation of the jacquard mechanism. The knitted structure of FIG. 3(c) is 1 of the structures called mesh textures, and is composed of the repeating units of 1-0/0-1/0-1/0-0// c.

In the case of the knitted open weave in fig. 3(c), the front jacquard yarn does not connect the stitch formed by the yarns supplied from the guide bars GB2 and GB8 to the adjacent wale. In the open weave structure of fig. 3(c), the front guide bars JB3 and JB4 are knitted into the front base fabric 1 and the rear base fabric 2 by front needle lapping with respect to the front knitting needle array FN and the rear knitting needle array BN. For this purpose, the front base fabric 1 and the rear base fabric 2 are connected.

Fig. 3(d) and (e) show an example of a knitting structure in the case where the front guide bars JB3 and JB4 are laid with the front inlay yarn with respect to the rear knitting needle row BN by the operation of the jacquard mechanism. The braided structure of FIG. 3(d) is composed of repeating units of 1-1/2-3/2-2/1-0// L. The braided structure of FIG. 3(e) is composed of repeating units of 1-1/1-2/2-2/1-0// g.

In this way, the front guide bars JB3, JB4 perform the front needle lapping with respect to the rear side knitting needle row BN, whereby the front guide yarns are knitted into the rear side base fabric 2. At this time, the front jacquard yarn is exposed on the surface of the rear base fabric 2 (the surface on the rear side of the warp knitted fabric 10).

Here, the front effect yarn reciprocates in the wale direction by 3 pitches in 1 repeating unit while forming a needle loop in the case of knitting the knitting structure of fig. 3(d), and reciprocates in the wale direction by 2 pitches in 1 repeating unit while forming a needle loop in the case of knitting the knitting structure of fig. 3 (e). For this purpose, the front yarn connects different wales of the knit stitch formed by the yarn supplied from the guide bar GB8 to each other. In addition, the knitted fabric of fig. 3(d) has a larger shogging width in the wale direction (weft direction) as compared with the knitted fabric of fig. 3(e), and the back side base fabric 2 is thickened accordingly.

In fig. 4, the basic structure formed by the back jacquard guide bars JB6, JB7 is shown by a broken line, and an example of the knitting structure formed by the back jacquard guide bars JB6, JB7 when the jacquard mechanism is operated is shown by a solid line.

Fig. 4(a) and (b) show an example of a knitting structure in the case where the back jacquard guide bars JB6 and JB7 are laid with the front inlay yarn with respect to the back knitting needle row BN by the operation of the jacquard mechanism. The braided structure of FIG. 4(a) is 1 in the structure called a texture of pachynsis, and is composed of 1-1/2-3/2-2/1-0// repeating unit. The braided structure of FIG. 4(b) is 1 in the structure called a thin texture, and is composed of a repeating unit of 0-0/1-2/1-1/1-0// g.

In this way, the back jacquard bars JB6, JB7 perform the front lay yarn with respect to the back knitting line BN, whereby the back side group cloth 2 is formed by the back jacquard yarn and the yarns supplied from the guide bars GB8, GB 9. At this time, the rear jacquard yarn is exposed on the surface of the rear base fabric 2 (the surface on the rear side of the warp knitted fabric 10).

Here, the rear jacquard yarn reciprocates in the wale direction by 3 pitches in 1 repeating unit while forming a needle loop in the case of knitting a thick texture in fig. 4(a), and reciprocates in the wale direction by 2 pitches in 1 repeating unit while forming a needle loop in the case of knitting a thin texture in fig. 4 (b). For this purpose, the jacquard yarns supplied from the rear jacquard bars JB6, JB7 connect the different wales of the knit stitch formed by the yarns supplied from the guide bar GB8 to one another. In addition, the thick texture of fig. 4(a) has a larger bar shog width in the wale direction (weft direction) than the thin texture of fig. 4(b), and the back side base fabric 2 is thickened accordingly.

Fig. 4(c) shows an example of a knitting structure in the case where the back jacquard guide bars JB6 and JB7 are laid only in the same wale by the action of the jacquard mechanism. The knitted structure of FIG. 4(c) is 1 of the structures called mesh texture, and is composed of the repeating units of 1-0/0-1/1-1/1-0// o.

In the case of the back jacquard yarn knitted in the mesh weave of fig. 4(c), the stitch structure formed by the yarns supplied from the guide bars GB2 and GB8 is not connected to the adjacent wale. In the texture of the mesh of fig. 4(c), the back jacquard bars JB6, JB7 are knitted with front inlay yarns for the front side knitted needle row FN and the back side knitted needle row BN, and the back jacquard yarns are knitted into the front side base fabric 1 and the back side base fabric 2. For this purpose, the front base fabric 1 and the rear base fabric 2 are connected.

Fig. 4(d) and (e) show examples of knitting structures when the back jacquard guide bars JB6 and JB7 are provided with inlay yarns for the front side knitting needle row FN by the operation of the jacquard mechanism. The braided structure of FIG. 4(d) is composed of repeating units of 1-0/2-2/2-3/1-1// g. The braided structure of FIG. 4(e) is composed of repeating units of 1-0/1-1/1-2/0-0// g.

In this way, the back jacquard bars JB6, JB7 carry the front inlay yarn with respect to the front side knitting needle row FN, whereby the back jacquard yarn is knitted into the front side group fabric 1. At this time, the rear jacquard yarn is exposed on the surface of the front base fabric 1 (the surface on the front side of the warp knitted fabric 10).

Here, the rear jacquard yarn reciprocates in the wale direction by 3 pitches in 1 repeating unit while forming a needle loop in the case of the knitting structure of fig. 4(d), and reciprocates in the wale direction by 2 pitches in 1 repeating unit while forming a needle loop in the case of the knitting structure of fig. 4 (e). For this purpose, the rear jacquard yarn connects different wales of the pillar stitch formed by the yarn supplied from the guide bar GB2 to each other. In the knitting structure of fig. 4(d), the shogging width in the wale direction (weft direction) is larger than that of the knitting structure of fig. 4(e), and the front base fabric 1 is thickened accordingly.

In

embodiment

1, 1 knitted structure in fig. 3(a) to (e) is selected as a knitted structure based on the prerequisite guide bars JB3 and JB4 at each knitting position. Accordingly, 1 knitted structure in fig. 4(a) to (e) is selected as a knitted structure by the back jacquard guide bars JB6 and JB7 at each knitting position. In this way, a combination of the knitting structure formed by the front jacquard bars JB3, JB4 and the knitting structure formed by the rear jacquard bars JB6, JB7 is achieved in each knitting position.

In this combination order, it is possible to form holes in the warp knit 10 or to make specific yarns appear on the surface of the front and rear sides of the warp knit 10. Further, by changing the combination of the knitting positions, a jacquard pattern can be formed on the front and rear surfaces of the warp knitted fabric 10. But also can form the concave-convex consistent with the jacquard pattern.

For example, as the knitting structure based on the front guide bars JB3 and JB4 at a certain position, the knitting structure for the front inlay yarn with respect to the front knitting needle row FN shown in fig. 3(a) or (b) is selected, and as the knitting structure based on the rear guide bars JB6 and JB7 at the same position, the knitting structure for the front inlay yarn with respect to the rear knitting needle row BN shown in fig. 4(a) or (b) is selected. In this case, the front jacquard yarn is exposed on the front surface of the warp knit fabric 10, and the rear jacquard yarn is exposed on the rear surface. In this case, the front base fabric 1 and the rear base fabric 2 are not connected.

Further, as the knitting structure formed by the front guide bars JB3 and JB4 at a certain position, a knitting structure in which the front inlay yarn is performed with respect to the rear knitting needle row BN shown in fig. 3(d) or (e) is selected, and as the knitting structure formed by the rear guide bars JB6 and JB7 at the same position, a knitting structure in which the front inlay yarn is performed with respect to the front knitting needle row FN shown in fig. 4(d) or (e) is selected. In this case, the back jacquard yarn mainly appears on the surface of the front side of the warp knit fabric 10, and the front jacquard yarn mainly appears on the surface of the back side. In this case, the front stitch yarn laying by the front jacquard guide bars JB3 and JB4 with respect to the rear knitting needle row BN and the front stitch yarn laying by the rear pair of rear jacquard guide bars JB6 and JB7 with respect to the front knitting needle row FN are alternately performed, and the sinker loop of the front jacquard yarn and the sinker loop of the rear jacquard yarn are alternately wound. Thereby, the front base fabric 1 and the rear base fabric 2 are pulled against each other and joined.

In this way, a portion where the front jacquard yarn is exposed and a portion where the rear jacquard yarn is exposed are formed on the surface of the front side of the warp knit fabric 10. Then, by supplying different kinds of yarns to the front jacquard guide bars JB3 and JB4 and the rear jacquard guide bars JB6 and JB7, a jacquard pattern is formed on the front side surface of the warp knitted fabric 10. Also, a portion exposing the front jacquard yarn is formed on the surface of the rear side of the warp knit fabric 10, and a portion exposing the rear jacquard yarn is formed on the surface of the rear side of the warp knit fabric. Then, by supplying different kinds of yarns to the front jacquard guide bars JB3, JB4 and the rear jacquard guide bars JB6, JB7, a jacquard pattern is formed on the rear side surface of the warp knitted fabric 10.

The different type of yarn means at least 1 yarn different in color, luster, ease of dyeing, style, and the like.

Then, the insert yarn inserted by the guide bar GB5 is inserted between the front base fabric 1 and the rear base fabric 2. At the connection position where the front base fabric 1 and the rear base fabric 2 are connected, the insert yarn inserted by the guide bar GB5 is pressed and compressed by the front base fabric 1 and the rear base fabric 2. Therefore, the warp knitted fabric 10 does not bulge to the front side or the rear side in the portion constituted by the connecting position of the front base fabric 1 and the rear base fabric 2.

On the other hand, at the non-coupling position where the front base fabric 1 and the rear base fabric 2 are not coupled, the insert yarn inserted by the guide bar GB5 is not compressed because it is not pressed by the front base fabric 1 and the rear base fabric 2. Therefore, the warp knitted fabric 10 bulges out to at least one of the front side or the rear side in the portion constituted by the non-connected position of the front base fabric 1 and the rear base fabric 2.

In this way, the surface of the warp knitted fabric 10 is formed with irregularities composed of concave portions as non-bulging portions and convex portions as bulging portions in conformity with the jacquard pattern.

For reference, fig. 5 shows a case where unevenness is formed on the warp knit 10. As shown in the drawing, at the connecting position 5 where the front base fabric 1 and the rear base fabric 2 are connected by the jacquard yarn 3, the insert yarn (not shown) inserted by the guide bar GB5 is pressed and compressed by the front base fabric 1 and the rear base fabric 2. On the other hand, at the non-connecting position 6 where the front base fabric 1 and the back base fabric 2 are not connected by the jacquard yarn 3, the inserted yarn 4 is not compressed, and the warp knitted fabric 10 is expanded. In this way, by forming the bulging positions and the positions where the bulging is not performed, the warp knitted fabric 10 is formed with irregularities.

In addition, if the sinker loop of the jacquard yarn in one of the front base fabric 1 and the rear base fabric 2 is longer than the sinker loop of the jacquard yarn in the other base fabric in the bulged portion where the front base fabric 1 and the rear base fabric 2 are not connected, the warp knitted fabric 10 is more bulged in the base fabric side where the sinker loop is longer.

For example, as the knitting structure formed by the front guide bars JB3 and JB4, the thick texture of fig. 3(a) in which the front base fabric 1 is formed with stitches and reciprocated by 3 stitches in the wale direction is selected. Subsequently, as a knitting structure formed by the rear jacquard guide bars JB6 and JB7, a thin structure of fig. 4(b) in which stitches are formed in the rear base fabric 2 and the needle pitch is reciprocated in the wale direction is selected. In this case, the sinker loop of the jacquard yarn in the front base fabric 1 is longer than that of the jacquard yarn in the rear base fabric 2, and therefore, the warp knit fabric 10 bulges more to the front side.

The open weave of fig. 3(c) was selected as the knit weave formed by the front jacquard bars JB3 and JB4 at a certain position, and the open weave of fig. 4(c) was selected as the knit weave formed by the rear jacquard bars JB6 and JB7 at the same position. As a result, the non-connecting position where the adjacent wales in the front base fabric 1 are not connected and the non-connecting position where the adjacent wales in the rear base fabric 2 are not connected coincide in the front-rear direction, and a hole is formed at the position in the warp knitted fabric 10. Here, since the front base fabric 1 and the rear base fabric 2 are connected to each other by the mesh texture in fig. 3(c) and the mesh texture in fig. 4(c) as described above, the front base fabric 1 and the rear base fabric 2 are connected to each other at the opening ends of the holes.

The raw material and the thickness (fineness) of the yarn used in embodiment 1 are not limited. As the yarn, various yarns such as filament yarn and spun yarn can be used. As the material of the yarn, natural fibers such as silk and cotton, synthetic fibers such as polyester and nylon, and the like can be used.

If the thickness of the inserted yarn inserted from the guide bar GB5 is changed, the amount of swelling of the warp knitted fabric 10 is changed. In order to increase the amount of the warp knitted fabric 10 to be bulked, the inserted yarn to be supplied to the guide bar GB5 is preferably made thicker, and the fixed-length count (dtex) is more preferably 3 times or more the jacquard yarn.

For example, polyester yarns of 100dtex or less are supplied to the guide bars GB2, GB8, polyester yarns of 100 to 200dtex are supplied to the guide bar GB9, polyester yarns of 100 to 200dtex are supplied to the jacquard bars JB3, JB4, JB6, JB7, and polyester yarns of 500 to 700dtex are supplied to the guide bar GB 5.

The raw material and thickness of the yarn are the same as those described above in

embodiments

2 and 3 below.

(4) Specific example of warp knit fabric 10

Fig. 6 illustrates the front side of the warp knitted fabric 10 knitted in the above knitting example 1. This warp knitted fabric 10 integrally knits an upper portion 11 for an upper and a peripheral portion 12 thereof. The upper portion 11 has a pattern of toe 20, front portion 21, nail 22, side portions 23, upper portion 24, rear portion 25, and heel 26.

In the knitting of the warp knitted fabric 10 described below, orange yarns are supplied to the front jacquard guide bars JB3, JB4, and white yarns are supplied to the guide bars GB2, GB5, GB8, GB9 and the back jacquard guide bars JB6, JB 7.

The knitting structure of fig. 2 is formed by guide bars GB2, GB5, GB8, and GB9 in the upper portion 11 and the peripheral portion 12. The knitting structure described below is formed by front pattern guide bars JB3 and JB4 and rear pattern guide bars JB6 and JB 7.

In the toe portion 20, the thick texture of fig. 3(a) is formed by the front pattern guide bars JB3 and JB4, and the thin texture of fig. 4(b) is formed by the rear pattern guide bars JB6 and JB 7. Therefore, the front surface of the toe portion 20 becomes orange as the color of the yarn supplied from the front jacquard guide bars JB3, JB 4. Since the front base fabric 1 and the rear base fabric 2 are not connected, the toe part 20 bulges to be convex.

In the front part 21 and the nail part 22, the knitting structure of fig. 3(d) is formed by the front jacquard guide bars JB3 and JB4, and the knitting structure of fig. 4(d) is formed by the rear jacquard guide bars JB6 and JB 7. Therefore, the front surfaces of the front portion 21 and the nail portion 22 are white as colors supplied from the back jacquard guide bars JB6 and JB 7.

Further, at a plurality of positions in the front part 21 and the nail part 22, the open texture of fig. 3(c) is formed by the front pattern guide bars JB3 and JB4, and the open texture of fig. 4(c) is formed by the rear pattern guide bars JB6 and JB 7. And a plurality of holes 30 are formed therefrom. These holes 30 become ventilation holes in the shoe. In the open weave structure of fig. 3(c), since the front guide bars JB3 and JB4 also carry the front knit stitch yarn with respect to the front knitted stitch FN, the orange yarn is visible also at the opening ends of the holes 30 in the front surfaces of the front part 21 and the nail part 22.

In the front portion 21 and the nail portion 22, since the front base cloth 1 and the rear base cloth 2 are connected, the insert yarn inserted by the guide bar GB5 is pressed and compressed from the front side and the rear side. Therefore, the front portion 21 and the nail portion 22 do not bulge.

In the upper portion 24, the portion formed of the knitting structure of fig. 3(d) and 4(d) and the portion formed of the knitting structure of fig. 3(e) and 4(e) are arranged so as to form a checkered pattern. Therefore, the front surface of the upper portion 24 is white, which is the color of the yarn supplied from the back jacquard guide bars JB6, JB 7. However, in the portion constituted by the knitted structure in fig. 3(e) and 4(e), a little orange yarn can be seen from the front surface. This is because the knitted structure of fig. 3(e) and 4(e) is used to make a relatively thin fabric, and orange is a striking color. In addition, since the front base fabric 1 and the rear base fabric 2 are connected to each other regardless of the combination of knitting structures, the inserted yarn inserted by the guide bar GB5 is pressed and compressed in the upper portion 24 formed of these knitting structures. For this reason, the upper portion 24 does not bulge out.

The open weave of fig. 3(c) is formed by the front pattern guide bars JB3 and JB4, and the open weave of fig. 4(c) is formed by the rear pattern guide bars JB6 and JB7 at a plurality of predetermined positions of the upper portion 24. This forms holes 31 at a plurality of predetermined positions in upper portion 24. These holes 31 become holes for passing through the shoelace. Similarly to the hole 30, the orange yarn can be seen from the front side at the opening end of the hole 31 of the upper portion 24.

In the side portion 23, the 1 st straight portion 36 composed of the knitting structure of fig. 3(d) and 4(d) and the 2 nd straight portion 37 composed of the knitting structure of fig. 3(a) and 4(a) are formed as oblique straight lines and are alternately arranged. Since the colors of the 1 st straight portion 36 formed of the knitted structure of fig. 3(d) and 4(d) and the 2 nd straight portion 37 formed of the knitted structure of fig. 3(a) and 4(a) are reversed, the side portion 23 is formed in a stripe pattern of orange and white. On the front surface, the 1 st linear portion 36 composed of the knitted structure of fig. 3(d) and 4(d) is white, and the 2 nd linear portion 37 composed of the knitted structure of fig. 3(a) and 4(a) is orange.

In the side portion 23, the knitted structure of fig. 3(d) and 4(d) connects the front base fabric 1 and the rear base fabric 2, and therefore the 1 st straight portion 36 constituted by these knitted structures does not bulge. On the other hand, since the knitted structure of fig. 3(a) and 4(a) does not connect the front base fabric 1 and the rear base fabric 2, the 2 nd linear portion 37 formed by these knitted structures bulges. As a result, the side portion 23 is formed with irregularities conforming to the stripe pattern.

In the rear part 25, the thick texture of fig. 3(a) is formed by the front pattern guide bars JB3 and JB4, and the thin texture of fig. 4(b) is formed by the rear pattern guide bars JB6 and JB 7. Therefore, the front surface of the back portion 25 becomes orange as the color of the yarn supplied from the front jacquard guide bars JB3, JB 4. Since the front base fabric 1 and the rear base fabric 2 are not connected, the rear portion 25 bulges and becomes convex.

In addition, at a plurality of predetermined positions in the rear portion 25, the mesh texture of fig. 3(c) is formed by the front pattern guide bars JB3 and JB4, and the mesh texture of fig. 4(c) is formed by the rear pattern guide bars JB6 and JB 7. This forms holes 32 at a plurality of predetermined positions in the rear portion 25. The front base fabric 1 and the rear base fabric 2 are connected to each other at the opening ends of the holes 32. These holes 32 become ventilation holes in the shoe.

In the heel 26, the knit structure of fig. 3(d) is formed by the front jacquard guide bars JB3 and JB4, and the knit structure of fig. 4(d) is formed by the rear jacquard guide bars JB6 and JB 7. In the portion constituted by the knitting structure of fig. 3(d) and fig. 4(d), the front surface is white as the color of the yarn supplied from the back jacquard guide bars JB6, JB 7.

In the heel portion 26, a quadrangular portion 35 formed of the knitting structure shown in fig. 3(a) and 4(b) is arranged periodically. In the portion constituted by the knitting structure of fig. 3(a) and 4(b), the front surface is orange as the color of the yarn supplied from the front jacquard guide bars JB3, JB 4. As a result, on the front surface of the heel 26, a jacquard pattern is formed in which orange quadrangular portions 35 are periodically arranged on a white ground.

In the heel portion 26, the front base fabric 1 and the rear base fabric 2 are connected to each other at a portion formed by the knitting structure of fig. 3(d) and 4(d), and the front base fabric 1 and the rear base fabric 2 are not connected to each other at a quadrangular portion 35 formed by the knitting structure of fig. 3(a) and 4 (b). Therefore, the orange quadrangular portion 35 formed of the knitted structure of fig. 3(a) and 4(b) bulges out around the portion.

The boundary between the above-mentioned parts is, for example, a knitted structure similar to the toe part 20. Thus, the boundary portion of each portion becomes a clear boundary line which is orange and bulges on the front surface of the warp knitted fabric 10.

As described above, on the front surface of the warp knitted fabric 10, the toe portion 20, the 2 nd linear portion 37 of the side portion 23, the rear portion 25, the square portion 35 of the heel portion 26, and the boundary portion between the portions are orange and convex, and the portions other than the 1 st linear portion 36 of the front portion 21, the nail portion 22, the upper portion 24, and the square portion 35 of the side portion 23 and the square portion 35 of the heel portion 26 are white and concave portions which are not convex. In this way, a jacquard pattern and unevenness corresponding thereto are formed on the front surface of the warp knitted fabric 10.

In addition, on the surface of the back side of the warp knitted fabric 10, one of the front jacquard yarn and the back jacquard yarn, which is not exposed on the surface of the front side, is exposed. Therefore, a jacquard pattern is formed on the surface of the rear side, wherein the color of the jacquard pattern is reversed from that of the surface of the front side.

As described above, a jacquard pattern is formed on the front base fabric 1 and the back base fabric 2 of the warp knitted fabric 10, and further, unevenness conforming to the jacquard pattern is formed.

In the peripheral portion 12, the portion of the knitting structure shown in fig. 3(d) and 4(d) and the portion of the knitting structure shown in fig. 3(b) and 4(b) are alternately formed for each predetermined course. Thereby, the front base fabric 1 and the rear base fabric 2 are connected.

(5) Post-knitting process

The knitted warp knitted fabric 10 is heated by boiling or the like in order to increase the volume of the convex portion. The heating is carried out, for example, at 95 to 100 ℃ for 20 to 30 minutes. Then, the knitted warp knit fabric 10 is subjected to finishing such as heat finishing. In the finished warp knitted fabric 10, the height of the convex portion (height from the bottom of the surface of the concave portion to the apex of the convex portion) is preferably 1mm or more, and more preferably 2mm or more.

In the warp knitted fabric 10 actually knitted by the double raschel machine, a plurality of upper portions 11 are arranged vertically and horizontally. In an appropriate step after knitting, a plurality of upper portions 11 are cut out from 1 piece of the warp knitted fabric 10.

(6) Effect

In the warp knitting machine according to embodiment 1, the guide bar GB5 is provided between the front jacquard bars JB3, JB4 and the rear jacquard bars JB6, JB 7. For this purpose, an insert yarn may be inserted between the front base fabric 1 and the rear base fabric 2.

In the knitting of the warp knitted fabric 10, the front pattern guide bars JB3, JB4 and the rear pattern guide bars JB6, JB7 form a pattern on the surface of the front base fabric 1 (i.e., the surface on the front side of the warp knitted fabric 10) and the surface of the rear base fabric 2 (i.e., the surface on the rear side of the warp knitted fabric 10) by the jacquard yarn, and simultaneously connect the front base fabric 1 and the rear base fabric 2. At this time, the inserted yarn inserted between the front base fabric 1 and the rear base fabric 2 is pressed from the front side and the rear side at the position where the front base fabric 1 and the rear base fabric 2 are connected, and is not pressed and is not compressed at the position where the front base fabric 1 and the rear base fabric 2 are not connected.

As a result of knitting by such a method, the warp knitted fabric 10 does not swell at the connecting position between the front base fabric 1 and the rear base fabric 2, but swells at the non-connecting position. In this way, the warp knitted fabric 10 is formed with irregularities conforming to the pattern.

Here, the front guide bar GB2 and the rear guide bar GB8 are knitted into a knitted chain structure, and the front pattern bars JB3 and JB4 and the rear pattern bars JB6 and JB7 form a connecting position where adjacent wales of the knitted chain structure are connected and a non-connecting position where the adjacent wales are not connected, with a jacquard yarn. Then, the

holes

30, 31, 32 are formed in the warp knitted fabric 10 by aligning the non-connected position of the wale adjacent to the knitting structure on the front side with the non-connected position of the wale adjacent to the knitting structure on the rear side in the front-rear direction (front-rear direction of the warp knitted fabric 10). For this reason, holes in the warp knit fabric 10 such as ventilation holes in the upper and holes for the shoelace are easily formed.

The warp knitted fabric 10 and the upper having the warp knitted fabric 10 manufactured in this way can be easily manufactured, and have excellent design properties by forming irregularities in accordance with a pattern.

2. Embodiment mode 2

The structure of the warp knitting machine and the basic method of producing a warp knitted fabric in embodiment 2 are the same as those in embodiment 1.

(1) Specific formulation example 2

Fig. 7 shows a knitting structure diagram of a knitting example of embodiment 2. In the knitting example of embodiment 2, guide bars GB2, GB5, GB8 and GB9, and jacquard bars JB3, JB4, JB6 and JB7 are also used for knitting.

In this knitting, yarns are fed to guide bars GB2, GB5, GB8, and GB9, respectively, and are fully penetrated. Furthermore, the front jacquard guide bars JB3 and JB4 and the rear jacquard guide bars JB6 and JB7 are supplied with yarn to form full-penetration.

As shown in FIG. 7(a), the knitting structure of the guide bar GB2 is a pillar stitch in which stitches are formed by the same wales, and is constituted by a repeating unit of 0-1/1-1/1-0/0-0// or more. The knitting structure of the guide bar GB5 shown in FIG. 7(c) is an insertion structure comprising repeating units of 0-0/1-1/1-1/1-1/1-1/0-0/0-0/0-0// or more. The knitting structure of the guide bar GB8 shown in FIG. 7(e) is a pillar stitch and is composed of a repeating unit of 1-1/1-0/0-0/0-1// or more. The knitting structure of the guide bar GB9 shown in FIG. 7(f) is an insertion structure comprising 1-1/0-0/0-0/1-1// repeating units.

In this way, the guide bars GB2 and GB8 are used to form stitches from all the wales and courses of the front base fabric 1 and the rear base fabric 2. Here, the knitting structure formed by the guide bar GB2 and the guide bar GB8 is a chain structure, and therefore, adjacent wales are not connected to each other without a jacquard yarn. As described later, the jacquard yarn connects adjacent wales to each other.

The inserted yarn inserted by the guide bar GB5 plays a role of expanding the warp knitted fabric as described later. Also, the insert yarn inserted by the guide bar GB9 plays a role of reinforcing the warp knitting fabric.

Fig. 7 shows a basic structure formed by the jacquard guide bars JB3, JB4, JB6, and JB7, that is, a knitted structure formed by the jacquard guide bars JB3, JB4, JB6, and JB7 when the jacquard mechanism is not operated. The basic structure based on the pre-guide bars JB3 and JB4 shown in FIG. 7(b) is composed of repeating units of 1-0/1-1/1-2/0-0// B. The basic structure formed by the back jacquard guide bars JB6 and JB7 shown in FIG. 7(d) is composed of 1-1/1-2/2-2/1-0// repeating units.

In fig. 8, the basic structure formed by the front pattern bars JB3 and JB4 is shown by broken lines, and the knitting structure formed by the front pattern bars JB3 and JB4 is shown by solid lines when the jacquard mechanism is operated.

Fig. 8(a) shows an example of a knitting structure in the case where the front guide bars JB3, JB4 are laid with the front inlay yarn with respect to the front knitting needle row FN by the operation of the jacquard mechanism. The braided structure of FIG. 8(a) is 1 in the structure called "pre-pachynsis structure" and is composed of 1-0/1-1/2-3/1-1// repeating unit. In this way, the front base fabric 1 is formed of the front jacquard yarns and the yarns supplied from the guide bar GB2 by the front jacquard guide bars JB3, JB4 performing the needle front lapping with respect to the front knitting needle row FN. The front jacquard yarn is exposed on the surface (front side surface) of the front base fabric 1.

Here, the front effect yarn reciprocates in the wale direction by 3 pitches in 1 repeat unit while forming a needle loop. For this purpose, the front yarn is a yarn that connects different wales of a knit stitch formed by a yarn supplied from a guide bar GB 2.

Fig. 8(b) shows an example of a knitting structure in the case where the front guide bars JB3 and JB4 carry out the inlay knitting with respect to both the front knitting needle row FN and the rear knitting needle row BN by the operation of the jacquard mechanism. The braided structure of FIG. 8(b) is composed of repeating units of 1-0/1-1/2-3/1-0// L. Therefore, the front needle row FN is subjected to the pre-needle lapping 1 time, and for this, the rear needle row BN is subjected to the pre-needle lapping 1 time. In this way, the front guide bars JB3 and JB4 perform front needle lapping with respect to both the front knitting needle row FN and the rear knitting needle row BN, thereby connecting the front base fabric 1 and the rear base fabric 2.

Here, the front effect yarn reciprocates in the wale direction by 3 pitches in 1 repeat unit while forming a needle loop. For this purpose, the front yarn is formed by connecting different wales of a knit stitch formed by the yarn supplied from the guide bar GB2 and a knit stitch formed by the yarn supplied from the guide bar GB 8.

Fig. 8(c) shows an example of a knitting structure in the case where the front guide bars JB3, JB4 perform the front lay yarn with respect to the rear knitting line BN by the operation of the jacquard mechanism. The braided structure of FIG. 8(c) is 1 in the structure called posterior parenchymal structure, and is composed of 1-1/1-2/2-2/1-0// repeating unit. In this way, the front jacquard bars JB3, JB4 carry the front inlay yarn with respect to the rear knitting needle row BN, so that the front jacquard yarn is knitted into the rear side group fabric 2. At this time, the front jacquard yarn is exposed on the surface (rear surface) of the rear base fabric 2.

Here, the front effect yarn reciprocates in the wale direction by 2 pitches in 1 repeat unit while forming a needle loop. For this purpose, the front yarn is a yarn that connects different wales of a knit stitch formed by a yarn supplied from a guide bar GB 8.

Fig. 8(d) shows an example of a knitting structure in the case where the jacquard guide bars JB3 and JB4 are laid only in the same wale by the operation of the jacquard mechanism. The knitted structure in FIG. 8(d) is 1 in the structure called a mesh texture, and is composed of the repeating unit of 1-0/0-1/0-1/0-0// or more. In this case, the front yarn does not connect adjacent wales of the stitch pattern formed by the yarns supplied from the guide bars GB2 and GB 8.

In the knitting structure of fig. 8(d), the front base fabric 1 and the rear base fabric 2 are connected to each other by the front guide bars JB3 and JB4 performing front needle lapping with respect to the front knitting needle array FN and the rear knitting needle array BN and the front yarn being knitted into the front base fabric 1 and the rear base fabric 2.

Fig. 8(e) shows an example of a knitting structure in the case where the jacquard guide bars JB3 and JB4 are laid only in the same wale by the operation of the jacquard mechanism. The knitted structure in FIG. 8(e) is 1 in the structure called a mesh texture, and is composed of the repeating unit of 1-0/0-0/0-1/0-0// or more. In this case, the front yarn does not connect adjacent wales of the knitting structure formed by the yarns supplied from the guide bars GB2 and GB 8. Further, the front jacquard bars JB3, JB4 perform the front inlay yarn only with respect to the front knitting needle row FN, and therefore the front jacquard yarn does not connect the front base fabric 1 and the back base fabric 2.

In fig. 9, the basic structure formed by the back jacquard guide bars JB6 and JB7 is shown by broken lines, and the knitting structure formed by the back jacquard guide bars JB6 and JB7 when the jacquard mechanism is operated is shown by solid lines.

Fig. 9(a) shows an example of a knitting structure in the case where the back jacquard guide bars JB6, JB7 perform the inlay yarn on the back side knitting line BN by the operation of the jacquard mechanism. The braided structure of FIG. 9(a) is 1 in the structure called the posterior pachynsis structure, and is composed of the repeating unit of 2-2/2-3/2-2/1-0// L. In this way, the rear jacquard bars JB6, JB7 carry the front lay yarn with respect to the rear knitting line BN, so that the rear side group cloth 2 is formed by the rear jacquard yarn and the yarn fed from the guide bars GB8, GB 9. At this time, the rear jacquard yarn is exposed on the surface (rear surface) of the rear base fabric 2.

Here, the back jacquard yarn reciprocates in the wale direction by 3 pitches in 1 repeat unit while forming a needle loop. For this purpose, the back jacquard yarn connects different wales of a knit stitch formed by the yarn supplied from the guide bar GB 8.

Fig. 9(b) shows an example of a knitting structure in the case where the back jacquard guide bars JB6, JB7 carry out the inlay knitting with respect to both the front knitting needle row FN and the back knitting needle row BN by the operation of the jacquard mechanism. The braided structure of FIG. 9(b) consists of 2-2/2-3/2-3/1-0// repeating units. Therefore, the front needle lapping is performed 2 times with respect to the rear needle row BN, and for this, the front needle lapping is performed 1 time with respect to the front needle row FN. In this way, the rear jacquard guide bars JB6, JB7 perform front lapping with respect to both the front knitting needle row FN and the rear knitting needle row BN, thereby connecting the front base fabric 1 and the rear base fabric 2.

Here, the back jacquard yarn reciprocates in the wale direction by 3 pitches in 1 repeat unit while forming a needle loop. For this purpose, the back jacquard yarn connects different wales of a knit stitch formed by the yarn supplied from the guide bar GB2 and a knit stitch formed by the yarn supplied from the guide bar GB 8.

Fig. 9(c) shows an example of a knitting structure in the case where the back jacquard guide bars JB6, JB7 are laid with the front side knitting needle row FN by the operation of the jacquard mechanism. The braided structure of FIG. 9(c) is 1 of the structures called pre-parenchymal structures, and is composed of 1-0/1-1/1-2/0-0// repeating unit. In this way, the back jacquard bars JB6, JB7 carry the front inlay yarn with respect to the front side knitting needle row FN, so that the back jacquard yarn is knitted into the front side group fabric 1. The rear jacquard yarn is exposed on the surface (front side surface) of the front base fabric 1.

Here, the back jacquard yarn reciprocates in the wale direction by 2 pitches in 1 repeat unit while forming a needle loop. For this purpose, the back jacquard yarn connects different wales of a knit stitch formed by the yarn supplied from the guide bar GB 2.

Fig. 9(d) shows an example of a knitting structure in the case where the back jacquard guide bars JB6 and JB7 are laid only in the same wale by the operation of the jacquard mechanism. The knitted structure in FIG. 9(d) is 1 in the structure called a mesh texture, and is composed of the repeating unit of 1-0/0-1/1-1/1-0// or more. In this case, the back jacquard yarn does not connect adjacent wales of the stitch structure formed by the yarns supplied from the guide bars GB2 and GB 8. In the knitting structure of fig. 9(d), the front base fabric 1 and the rear base fabric 2 are connected to each other by knitting the rear jacquard yarns into the front base fabric 1 and the rear base fabric 2 by the front inlay yarns of the rear jacquard guide bars JB6 and JB7 with respect to the front knitting needle array FN and the rear knitting needle array BN.

Fig. 9(e) shows an example of a knitting structure in the case where the back jacquard guide bars JB6 and JB7 are laid only in the same wale by the operation of the jacquard mechanism. The knitted structure in FIG. 9(e) is 1 in the structure called a mesh texture, and is composed of the repeating unit of 1-1/0-1/1-1/1-0// or more. In this case, the back jacquard yarn does not connect adjacent wales of the stitch structure formed by the yarns supplied from the guide bars GB2 and GB 8. The back jacquard guide bars JB6, JB7 perform the front lapping only with respect to the back knitting line BN, and therefore the back jacquard yarn does not connect the front base fabric 1 and the back base fabric 2.

In

embodiment

2, 1 knitted structure in fig. 8(a) to (e) is selected as a knitted structure based on the prerequisite guide bars JB3 and JB4 at each knitting position. Accordingly, 1 knitted structure in fig. 9(a) to (e) is selected as a knitted structure by the back jacquard guide bars JB6 and JB7 at each knitting position. In this way, a combination of the knitted structure formed by the front jacquard guide bars JB3, JB4 and the knitted structure formed by the rear jacquard guide bars JB6, JB7 is achieved at each knitting position.

In this combination order, it is possible to make specific yarns appear on the front and back surfaces of the warp knit fabric while forming holes in the warp knit fabric. In addition, by changing the combination for each knitting position, a jacquard pattern can be formed on the front and rear surfaces of the warp knitted fabric. But also can form the concave-convex consistent with the jacquard pattern.

For example, the front bulky structure shown in fig. 8(a) is selected as the knitting structure formed by the front pattern guide bars JB3 and JB4 at a certain position, and the rear bulky structure shown in fig. 9(a) is selected as the knitting structure formed by the rear pattern guide bars JB6 and JB7 at the same position. In this case, the front jacquard yarn is exposed on the surface of the front side of the warp knitted fabric, and the rear jacquard yarn is exposed on the surface of the rear side. In this case, the front base fabric 1 and the rear base fabric 2 are not connected.

Further, as the knitting structure formed by the front guide bars JB3 and JB4 at a certain position, the rear thin texture shown in fig. 8(c) is selected, and as the knitting structure formed by the rear jacquard bars JB6 and JB7 at the same position, the front thin texture shown in fig. 9(c) is selected. In this case, the back jacquard yarn is exposed on the surface of the front side of the warp knitted fabric, and the front jacquard yarn is exposed on the surface of the back side. Also in this case, the sinker loops of the front jacquard yarn do not directly intersect the sinker loops of the rear jacquard yarn. However, both of the sinker loop of the front jacquard yarn and the sinker loop of the rear jacquard yarn are entangled with the insert yarn inserted by the guide bar GB 5. Thereby, the front base fabric 1 and the rear base fabric 2 are pulled against each other and joined.

The knit structure of fig. 8(b) is selected as the knit structure based on the front jacquard bars JB3 and JB4 at a certain position, and the knit structure of fig. 9(b) is selected as the knit structure based on the rear jacquard bars JB6 and JB7 at the same position. In this case, all the jacquard guide bars JB3, JB4, JB6, JB7 carry out front lay yarns for both the front knitted row FN and the rear knitted row BN, and therefore, the front base fabric 1 and the rear base fabric 2 are connected. However, the front jacquard guide bars JB3 and JB4 are laid with more yarn in the front knitting needle row FN than the rear jacquard guide bars JB6 and JB 7. For this reason, in this case, the front jacquard yarn is mainly exposed on the surface of the front side of the warp knit fabric.

In this way, a portion where the front jacquard yarn is exposed and a portion where the rear jacquard yarn is exposed are formed on the surface of the front side of the warp knitted fabric. Then, by supplying different kinds of yarns to the front jacquard guide bars JB3 and JB4 and the rear jacquard guide bars JB6 and JB7, a jacquard pattern is formed on the front side surface of the warp knitted fabric.

Also, a portion where the front jacquard yarn is exposed and a portion where the rear jacquard yarn is exposed are formed on the surface of the rear side of the warp knit fabric. Then, by supplying different kinds of yarns to the front jacquard guide bars JB3 and JB4 and the rear jacquard guide bars JB6 and JB7, a jacquard pattern is formed on the rear surface of the warp knitted fabric.

Then, an insert yarn inserted by the guide bar GB5 is inserted between the front base fabric 1 and the rear base fabric 2. The inserted yarn is compressed at the connecting position where the front base fabric 1 and the rear base fabric 2 are connected, and is not compressed at the non-connecting position where the front base fabric 1 and the rear base fabric 2 are not connected. As a result, the warp knitted fabric is formed with irregularities conforming to the jacquard pattern, which is the same as embodiment 1.

In the case of embodiment 2, on the front surface of the warp knitted fabric, a convex portion is formed to expose the front jacquard yarn formed by the combination of the knitting structures of fig. 8(a) and 9(a), a concave portion is formed to expose the rear jacquard yarn formed by the combination of the knitting structures of fig. 8(c) and 9(c), and a concave portion is formed to expose the front jacquard yarn formed by the combination of the knitting structures of fig. 8(b) and 9 (b). The concave portion is a portion formed by the connecting position of the front base fabric 1 and the rear base fabric 2.

In the portion where the front base fabric 1 and the rear base fabric 2 are not connected to each other and are raised, if the sinker loop of the jacquard yarn in one of the front base fabric 1 and the rear base fabric 2 is longer than the sinker loop of the jacquard yarn in the other base fabric, the warp knitted fabric is raised more on the base fabric side where the sinker loop is longer. This point is also the same as embodiment 1.

The open weave structure of fig. 8(d) or (e) is selected as the knit weave structure formed by the front guide bars JB3 and JB4 at a certain position, and the open weave structure of fig. 9(d) or (e) is selected as the knit weave structure formed by the back guide bars JB6 and JB7 at the same position. Thus, at this position, the adjacent wales in the front base fabric 1 and the rear base fabric 2 are not connected, and a hole is formed at this position in the warp knitted fabric. Here, the open weave of fig. 8(d) is selected as the knitting weave formed by the front jacquard bars JB3 and JB4, or the open weave of fig. 9(d) is selected as the knitting weave formed by the back jacquard bars JB6 and JB7, whereby the front base fabric 1 and the back base fabric 2 are connected to each other at the open ends of the holes of the warp knitted fabric.

(2) Specific example of warp knit fabric 110

Fig. 10 shows a front side surface of a warp knitted fabric 110 knitted in the above knitting example 2. This warp knitted fabric 110 integrally knits an upper portion 111 for an upper and a peripheral portion 112 thereof. The upper part 111 has a pattern of a toe 120, a front part 121, a side part 123, an upper part 124, and a rear part 125.

In the knitting of the warp knitted fabric 110 described below, a light gray yarn is supplied to the guide bar GB2 and the front pattern bars JB3 and JB4, and a dark gray yarn is supplied to the guide bars GB5, GB8 and GB9 and the rear pattern bars JB6 and JB 7.

The knitting structure of fig. 7 is formed by guide bars GB2, GB5, GB8, and GB9 in the upper portion 111 and the peripheral portion 112. The knitting structure described below is formed by front pattern guide bars JB3 and JB4 and rear pattern guide bars JB6 and JB 7.

In the toe part 120, the front thick ground structure of fig. 8(a) is formed by the front pattern guide bars JB3 and JB4, and the rear thick ground structure of fig. 9(a) is formed by the rear pattern guide bars JB6 and JB 7. Therefore, the front surface of the toe portion 120 is light gray, which is the color of the yarn supplied from the front jacquard guide bars JB3 and JB 4. Since the front base fabric 1 and the rear base fabric 2 are not connected, the toe portion 120 bulges and becomes convex.

In the front part 121, the front jacquard guide bars JB3 and JB4 form the knitting structure of fig. 8(b), and the rear jacquard guide bars JB6 and JB7 form the knitting structure of fig. 9 (b). Therefore, the front surface of the front portion 121 is light gray close to the color of the yarn supplied from the front jacquard guide bars JB3 and JB 4. In the front portion 121, since the front base fabric 1 and the rear base fabric 2 are connected, the insert yarn inserted by the guide bar GB5 is pressed and compressed from the front and rear sides. Therefore, the front portion 121 does not bulge out.

Further, at a plurality of positions in the front portion 121, the mesh texture of fig. 8(d) is formed by the front pattern guide bars JB3 and JB4, and the mesh texture of fig. 9(d) is formed by the rear pattern guide bars JB6 and JB 7. Thereby, a plurality of holes 130 are formed. These holes 130 become ventilation holes for the shoe.

In the upper part 124, the front jacquard guide bars JB3, JB4 form the knitting structure of fig. 8(b), and the rear jacquard guide bars JB6, JB7 form the knitting structure of fig. 9 (b). Therefore, the front surface of the upper part 124 is light gray close to the color of the yarn supplied from the front jacquard guide bars JB3, JB 4. In the upper portion 124, since the front base fabric 1 and the rear base fabric 2 are connected, the insert yarn inserted by the guide bar GB5 is pressed and compressed from the front and rear sides. For this reason, the upper portion 124 does not bulge out.

Further, at a plurality of positions in the upper part 124, the open weave of fig. 8(d) is formed by the front pattern bars JB3, JB4, and the open weave of fig. 9(d) is formed by the rear pattern bars JB6, JB 7. Thereby forming a plurality of holes 131. These holes 131 become holes in the shoe through which the shoelace is threaded.

The side section 123 has a rear weave pattern of fig. 8(c) formed by the front jacquard guide bars JB3 and JB4, and a front weave pattern of fig. 9(c) formed by the rear jacquard guide bars JB6 and JB 7. Therefore, the front surface of the side portion 123 is dark gray, which is the color of the yarn supplied from the back jacquard guide bars JB6 and JB 7. In the side portion 123, since the front base fabric 1 and the rear base fabric 2 are connected, the insert yarn inserted by the guide bar GB5 is pressed and compressed from the front side and the rear side. For this reason, the side portion 123 does not bulge out.

Further, a corrugated pattern portion 126 is formed on the side portion 123. In the pattern portion 126, the front thick weave of fig. 8(a) is formed by the front pattern guide bars JB3 and JB4, and the rear thick weave of fig. 9(a) is formed by the rear pattern guide bars JB6 and JB 7. Therefore, the front surface of the pattern portion 126 is light gray, which is the color of the yarn supplied from the front jacquard guide bars JB3 and JB 4. Since the front base fabric 1 and the rear base fabric 2 are not connected, the pattern portion 126 bulges and becomes convex.

In the rear part 125, the front jacquard guide bars JB3 and JB4 form the knitting structure of fig. 8(b), and the rear jacquard guide bars JB6 and JB7 form the knitting structure of fig. 9 (b). Therefore, the front surface of the rear portion 125 is light gray close to the color of the yarn supplied from the front jacquard guide bars JB3 and JB 4. In the rear portion 125, since the front base fabric 1 and the rear base fabric 2 are connected, the insert yarn inserted by the guide bar GB5 is pressed and compressed from the front side and the rear side. For this reason, the rear portion 125 does not bulge out.

Further, a corrugated pattern portion 127 is formed in the rear portion 125. In the pattern part 127, the front thick texture of fig. 8(a) is formed by the front pattern guide bars JB3 and JB4, and the rear thick texture of fig. 9(a) is formed by the rear pattern guide bars JB6 and JB 7. Therefore, the front surface of the pattern portion 127 is light gray, which is the color of the yarn supplied from the front jacquard guide bars JB3, JB 4. Since the front base fabric 1 and the rear base fabric 2 are not connected, the pattern portion 127 bulges and becomes convex.

The boundary between the above-mentioned parts is, for example, a knitted structure similar to the toe part 120. Thus, the boundary portion of each portion becomes a bright gray and expanded clear boundary line on the front surface of the warp knitted fabric 110.

As described above, on the front surface of the warp knitted fabric 110, the toe portion 120, the pattern portion 126 of the side portion 123, the pattern portion 127 of the back portion 125, and the boundary portion between the portions are convex portions that are bright gray and bulge out, the front portion 121, the upper portion 124, and the back portion 125 are concave portions that are bright gray and do not bulge out, and the side portion 123 is concave portions that are dark gray and do not bulge out. In this way, a jacquard pattern and unevenness corresponding thereto are formed on the front surface of the warp knitted fabric 110.

In addition, on the surface of the back side of warp knitted fabric 110, mainly the yarn of one of the yarns supplied from front jacquard bars JB3, JB4 and the yarn supplied from back jacquard bars JB6, JB7 that is not exposed on the surface of the front side is exposed. For this purpose, a jacquard pattern is formed on the rear surface, the color of which is reversed from that of the front surface.

As described above, a jacquard pattern is formed on the front base fabric 1 and the back base fabric 2 of the warp knitted fabric 110, and further, unevenness conforming to the jacquard pattern is formed.

In the peripheral portion 112, for example, the knitting structure of fig. 8(b) is formed by the front pattern guide bars JB3 and JB4, and the knitting structure of fig. 9(b) is formed by the rear pattern guide bars JB6 and JB 7. For this purpose, the front base fabric 1 is connected to the rear base fabric 2.

The warp knitted fabric 110 actually knitted by the double raschel machine is formed by arranging a plurality of upper-shaped portions in a vertical and horizontal direction. In an appropriate step after knitting, a plurality of upper portions 111 are cut and collected from 1 piece of the warp knitted fabric 110.

(3) Effect

According to embodiment 2, as in embodiment 1, unevenness corresponding to a pattern can be formed on the warp knitted fabric 110, and further, holes can be formed.

3. Embodiment 3

The structure of the warp knitting machine in embodiment 3 and the basic method for producing a warp knitted fabric are the same as those in embodiment 1.

(1) Specific preparation example 3

Fig. 11 shows a knitting structure diagram of a knitting example of embodiment 3. In the knitting example of embodiment 3, guide bars GB2, GB5, GB8, GB9, front pattern bars JB3, JB4, and back pattern bars JB6, JB7 are also used for knitting.

In this knitting, yarns are fed to guide bars GB2, GB5, GB8, and GB9, respectively, to make full-penetration. Also, the front and rear jacquard guide bars JB3, JB4, JB6, JB7, respectively, are supplied with yarn to make full-penetration.

As shown in FIG. 11(a), the knitting structure of the guide bar GB2 is constituted by the repeating unit of 1-0/0-0/1-2/1-1// and a warp-flat structure is formed on the front base fabric 1. The knitting structure of the guide bar GB5 shown in FIG. 11(c) is an insertion structure and is composed of repeating units of 0 to 0/1 to 1/1 to 1/0 to 0// c. The knitting structure of the guide bar GB8 shown in FIG. 11(e) is a pillar stitch and is composed of a repeating unit of 1-1/1-0/0-0/0-1// or more. The knitting structure of the guide bar GB9 shown in FIG. 11(f) is composed of the repeating units of 1-1/1-0/0-0/1-2// and forms a warp-flat structure on the rear base fabric 2.

In this way, the guide bars GB2 and GB8 and GB9 are used to form stitches from all the wales and courses of the front base fabric 1 and the rear base fabric 2. The insert yarn inserted by the guide bar GB5 acts to bulge the warp knit fabric.

Fig. 11 also shows the basic weave formed by the jacquard guide bars JB3, JB4, JB6, and JB7, i.e., the knitted weave formed by the jacquard guide bars JB3, JB4, JB6, and JB7 when the jacquard mechanism is not operated. The basic structure based on the pre-guide bars JB3 and JB4 shown in FIG. 11(b) is composed of repeating units of 1-0/1-1/1-1/1-0// B. The basic structure formed by the back jacquard guide bars JB6 and JB7 shown in FIG. 11(d) is composed of 0-0/0-1/0-1/0-0// repeating unit.

Fig. 12(a) shows an example of a knitting structure in the case where the front guide bars JB3, JB4 are laid with a front lay yarn with respect to the front knitting needle row FN by the operation of the jacquard mechanism. The braided structure of FIG. 12(a) is composed of repeating units of 1-0/1-1/1-2/1-1// g. In this way, the front pattern guide bars JB3, JB4 perform needle front lapping with respect to the front knitting needle row FN, and thereby the front base fabric 1 is formed by the front pattern yarns and the yarns supplied from the guide bar GB 2. The front jacquard yarn is exposed on the surface (front side surface) of the front base fabric 1.

Fig. 12(b) shows an example of a knitting structure in the case where the front guide bars JB3, JB4 perform the front lay yarn with respect to the rear knitting line BN by the operation of the jacquard mechanism. The braided structure of FIG. 12(b) is composed of repeating units of 1-1/1-2/1-1/1-0// L. In this way, the front jacquard bars JB3, JB4 carry the front inlay yarn with respect to the rear knitting needle row BN, so that the front jacquard yarn is knitted into the rear side group fabric 2. And the front jacquard yarn is exposed on the surface (rear side surface) of the rear base fabric 2.

Fig. 12(c) shows an example of a knitting structure in the case where the jacquard guide bars JB3 and JB4 are laid only in the same wale by the operation of the jacquard mechanism. The knitted structure in FIG. 12(c) is 1 in the structure called a mesh texture, and is composed of the repeating unit of 1-0/0-1/0-1/0-0// or more. In the knitting structure of fig. 12(c), the front base fabric 1 and the rear base fabric 2 are connected to each other by knitting the front yarn into the front base fabric 1 and the rear base fabric 2 by performing the front inlay knitting with respect to the front knitting needle row FN and the rear knitting needle row BN by the front knitting guide bars JB3 and JB 4.

In fig. 13, the basic structure formed by the back jacquard guide bars JB6 and JB7 is shown by broken lines, and the knitting structure formed by the back jacquard guide bars JB6 and JB7 when the jacquard mechanism is operated is shown by solid lines.

Fig. 13(a) shows an example of a knitting structure in the case where the back jacquard guide bars JB6, JB7 perform the inlay yarn for the back knitting line BN by the operation of the jacquard mechanism. The braided structure of FIG. 13(a) is composed of repeating units of 1-1/1-2/1-1/1-0// w. In this way, the back jacquard bars JB6, JB7 carry out the front lay yarn with respect to the back knitting line BN, so that the back side group cloth 2 is formed by the back jacquard yarn and the yarn supplied from the guide bars GB8, GB 9. And the rear jacquard yarn is exposed on the surface (rear side surface) of the rear base fabric 2.

Fig. 13(b) shows an example of a knitting structure in the case where the back jacquard guide bars JB6, JB7 are laid with the front side knitting needle row FN by the operation of the jacquard mechanism. The braided structure of FIG. 13(b) is composed of repeating units of 1-0/1-1/1-2/1-1// g. In this way, the back jacquard bars JB6, JB7 carry the front inlay yarn with respect to the front side knitting needle row FN, so that the back jacquard yarn is knitted into the front side group fabric 1. The rear jacquard yarn is exposed on the surface (front side surface) of the front base fabric 1.

Fig. 13(c) shows an example of a knitting structure in the case where the back jacquard guide bars JB6 and JB7 are laid only in the same wale by the action of the jacquard mechanism. The knitted structure in FIG. 13(c) is 1 in the structure called a mesh texture, and is composed of the repeating unit of 1-0/0-1/1-1/1-0// or more. In the knitting structure of fig. 13(c), the front base fabric 1 and the rear base fabric 2 are connected by the rear jacquard guide bars JB6, JB7 that knit the front inlay yarn with respect to the front knitting needle row FN and the rear knitting needle row BN and the rear jacquard yarn is knitted into the front base fabric 1 and the rear base fabric 2.

In

embodiment

3, 1 knitted structure in fig. 12(a) to (c) is selected as a knitted structure based on the prerequisite guide bars JB3 and JB4 at each knitting position. Accordingly, 1 knitted structure in fig. 13(a) to (c) is selected as a knitted structure by the back jacquard guide bars JB6 and JB7 at each knitting position. In this way, a combination of the knitting structure formed on the basis of the front jacquard bars JB3, JB4 and the knitting structure formed on the basis of the rear jacquard bars JB6, JB7 is achieved at each knitting position.

In this order of combination, specific yarns can be made to appear on the surface of the front and back sides of the warp knit. In addition, by changing the combination for each knitting position, a jacquard pattern can be formed on the front and rear surfaces of the warp knitted fabric. But also can form the concave-convex consistent with the jacquard pattern. Further, although not shown in fig. 11, it is also possible to form holes in the warp knitted fabric in the above-described combination order in the case of a knitting structure in which adjacent wales are not connected by the knitting structure formed based on the guide bars GB2, GB8, GB 9.

For example, as the knitting structure formed by the front pattern guide bars JB3 and JB4 at a certain position, the knitting structure for the front inlay yarn with respect to the front side knitting needle row FN shown in fig. 12(a) is selected, and as the knitting structure formed by the rear pattern guide bars JB6 and JB7 at the same position, the knitting structure for the front inlay yarn with respect to the rear side knitting needle row BN shown in fig. 13(a) is selected. In this case, the front jacquard yarn is exposed on the surface of the front side of the warp knitted fabric, and the rear jacquard yarn is exposed on the surface of the rear side. In this case, the front base fabric 1 and the rear base fabric 2 are not connected.

Further, as the knitting structure formed by the front pattern guide bars JB3 and JB4 at a certain position, the knitting structure for the front inlay yarn with respect to the rear side knitting needle row BN shown in fig. 12(b) is selected, and as the knitting structure formed by the rear pattern guide bars JB6 and JB7 at the same position, the knitting structure for the front inlay yarn with respect to the front side knitting needle row FN shown in fig. 13(b) is selected. In this case, the back jacquard yarn is exposed on the surface of the front side of the warp knitted fabric, and the front jacquard yarn is exposed on the surface of the back side. In this case, the front inlay yarn for the rear knitting needle row BN formed by the front pattern guide bars JB3 and JB4 and the front inlay yarn for the front knitting needle row FN formed by the rear pattern guide bars JB6 and JB7 are alternately wound so that the sinker loop of the front pattern yarn and the sinker loop of the rear pattern yarn are alternately wound. Thereby, the front base fabric 1 and the rear base fabric 2 are pulled and joined to each other.

In this way, a portion where the front jacquard yarn is exposed and a portion where the rear jacquard yarn is exposed are formed on the surface of the front side of the warp knitted fabric. Then, by supplying different kinds of yarns to the front jacquard guide bars JB3 and JB4 and the rear jacquard guide bars JB6 and JB7, a jacquard pattern is formed on the front side surface of the warp knitted fabric. Also, a portion where the front jacquard yarn is exposed and a portion where the rear jacquard yarn is exposed are formed on the surface of the rear side of the warp knit fabric. Then, by supplying different kinds of yarns to the front jacquard guide bars JB3, JB4 and the rear jacquard guide bars JB6, JB7, a jacquard pattern is formed on the rear side surface of the warp knitted fabric.

Then, an insert yarn inserted by the guide bar GB5 is inserted between the front base fabric 1 and the rear base fabric 2. This insert yarn is compressed at the connecting position where the front base fabric 1 and the rear base fabric 2 are connected and is not compressed at the non-connecting position where the front base fabric 1 and the rear base fabric 2 are not connected, whereby unevenness conforming to the jacquard pattern is formed on the warp knitted fabric. This point is the same as embodiment 1.

In embodiment 3 as well, if the sinker loop of the jacquard yarn in one of the front base fabric 1 and the rear base fabric 2 is longer than that of the jacquard yarn in the other base fabric, the warp knitted fabric is more greatly expanded on the base fabric side where the sinker loop is longer. This point is also the same as embodiment 1.

The open weave structure shown in fig. 12(c) is selected as the knitting structure formed by the front pattern guide bars JB3 and JB4 at a certain position, and the open weave structure shown in fig. 13(c) is selected as the knitting structure formed by the rear pattern guide bars JB6 and JB7 at the same position. Although not shown in fig. 11, as shown in fig. 2 and 7, as the knitting structure of guide bar GB2, the knitting structure of guide bar GB8, and the knitting structure of GB9, the insertion structure to the same wale only is selected. In this case, adjacent wales of the knitted stitch are not connected at the same position of the front base fabric 1 and the back base fabric 2, and therefore, a hole is formed at the position in the warp knitted fabric.

(2) Specific example of warp knit fabric 210

Fig. 14 shows a front side surface of a warp knitted fabric 210 knitted in the above knitting example 3. This warp knit fabric 210 can be used as a quilted product used in cold-proof clothes, bags, interior articles, and the like. The warp knitted fabric 210 has a pattern including a plurality of pattern portions 211 arranged in a longitudinal direction (warp direction, knitting direction) and a transverse direction (weft direction, width direction), and a line portion 212 dividing the pattern portions 211 from the pattern portions 211.

In the knitting of the warp knitted fabric 210 described below, orange yarns are supplied to the front jacquard guide bars JB3, JB4, and white yarns are supplied to the other guide bars GB2, GB5, GB8, GB9 and the rear jacquard guide bars JB6, JB 7.

The knitting structure of fig. 11 is formed by guide bars GB2, GB5, GB8, and GB9 in the pattern portion 211 and the thread portion 212. The front pattern guide bars JB3 and JB4 and the rear pattern guide bars JB6 and JB7 form a knitting structure described below.

In graphic section 211, the knitting structure of fig. 12(a) is formed by front jacquard guide bars JB3 and JB4, and the knitting structure of fig. 13(a) is formed by rear jacquard guide bars JB6 and JB 7. Therefore, the front surface of the graphic part 211 is orange as the color of the yarn supplied from the front jacquard guide bars JB3 and JB 4. Further, since the front base fabric 1 and the rear base fabric 2 are not connected, the insert yarn inserted by the guide bar GB5 is not compressed. Therefore, the pattern portion 211 bulges to become a convex portion.

In the line portion 212, the front jacquard guide bars JB3 and JB4 form the knitting structure of fig. 12(b), and the rear jacquard guide bars JB6 and JB7 form the knitting structure of fig. 13 (b). Therefore, the front surface of the yarn portion 212 is white, which is the color of the yarn supplied from the back jacquard guide bars JB6 and JB 7. Since the front base fabric 1 and the rear base fabric 2 are connected, the insert yarn inserted by the guide bar GB5 is compressed. Therefore, the wire portion 212 does not bulge out and becomes a concave portion.

As described above, on the front surface of the warp knitted fabric 210, the pattern portion 211 is a convex portion which is orange and bulges out, and the line portion 212 is a concave portion which is white and does not bulge out. In this way, a jacquard pattern and unevenness corresponding thereto are formed on the front surface of the warp knitted fabric 210.

Further, on the surface on the rear side of the warp knitted fabric 210, the yarn that is not exposed on the surface on the front side is mainly exposed from the yarn supplied from the front jacquard bars JB3, JB4 and the yarn supplied from the rear jacquard bars JB6, JB 7. Therefore, a jacquard pattern is formed on the surface of the rear side, wherein the color of the jacquard pattern is reversed from that of the surface of the front side.

As described above, a jacquard pattern including the pattern portion 211 and the thread portion 212 is formed on the front base fabric 1 and the rear base fabric 2 of the warp knitted fabric 210, and further, the unevenness is formed in accordance with the jacquard pattern. The line portions 212 correspond to sewn portions in the quilted product.

(3) Effect

In a conventional general method for producing quilted products, a front fabric and a back fabric are produced individually, a core material such as cotton is sandwiched between the front fabric and the back fabric, and finally, sewing is performed at a predetermined position.

However, according to embodiment 3, the front base cloth 1 as the front side cloth and the rear base cloth 2 as the back side cloth are simultaneously knitted, the insert yarn from the guide bar GB5 is inserted as the core material simultaneously with the knitting, and the front base cloth 1 and the rear base cloth 2 are connected simultaneously with the knitting. Therefore, according to embodiment 3, a quilted product having dramatically improved efficiency can be produced as compared with the conventional one.

Further, since the hole can be formed in the quilted product while knitting is performed as described above, the quilted product having the hole, which is remarkably improved in efficiency compared with the conventional one, can be manufactured.

4. Modification example

The above embodiments are illustrative, and the scope of the present invention is not limited thereto. Various omissions, substitutions, and changes may be made to the above-described embodiments without departing from the spirit of the invention. A modified example of the above embodiment will be described below.

First, the warp knitted fabrics of the above embodiments can be used for various articles such as clothing such as outerwear, interior products, interior materials for automobiles, ceiling materials, automobile materials such as sheets, medical products such as sanitary materials, medical clothing, bedding, chairs, back supports of backpacks, shoulder straps, and the like, in addition to the already exemplified upper and the like.

The knitting examples 1 to 3 are merely examples, and various knitting methods other than the knitting examples 1 to 3 can be carried out by the warp knitting machine of the above embodiment.

In the above embodiment, 2-color yarns are prepared, 1-color yarn is supplied to the front jacquard guide bars JB3 and JB4, and the remaining 1-color yarn is supplied to the guide bars GB2, GB5, GB8, GB9, and the rear jacquard guide bars JB6 and JB 7. However, the number of types of yarns used and the manner of supplying these yarns to the jacquard guide bar and the guide bar are not limited to the above-described embodiments.

For example, 3-color yarns may be prepared, and 1-color yarn may be supplied to the front jacquard guide bars JB3, JB4, the other 1-color yarn may be supplied to the back jacquard guide bars JB6, JB7, and the remaining 1-color yarn may be supplied to the guide bars GB2, GB5, GB8, GB 9.

Further, for example, the front jacquard bars JB3, JB4 or the rear jacquard bars JB6, JB7 supply yarns of a plurality of colors in such a manner that the colors vary in the width direction of the jacquard bars. In this case, a jacquard pattern is formed in which the color varies in the width direction (weft direction) of the warp knitting fabric.

In each of the above embodiments, the weft yarn may be inserted as an insert yarn between the front base fabric 1 and the rear base fabric 2 by using the same structure as that of the weft insertion raschel machine. Thereby, the weft yarn and the insert yarn inserted by the guide bar GB5 are inserted between the front base fabric 1 and the rear base fabric 2, and therefore, the warp knitted fabric can be more greatly expanded. However, if a weft yarn is inserted between the front base fabric 1 and the rear base fabric 2, all the adjacent wales are connected to each other, and therefore, holes cannot be formed in the warp knitted fabric.

Further, 2 or more guide bars may be provided between the front pair of jacquard guide bars and the rear pair of jacquard guide bars.
