Description

  The present invention is an improvement of a rib warp knitted fabric knitted by a double russell machine, more specifically, a rib warp knitting that is excellent in stretch back of the fabric and can exhibit a clear color effect when stretched by the color of the knitting yarn It is about the earth.

  A cross-cut surface in the width direction like a rib knitted fabric (rubber knitted fabric) of a weft (horizontal) knitting method by integrating a plurality of wale knitted belts alternately with needle rows before and after the double raschel machine with a connecting thread Is corrugated, and a warp knitted fabric that greatly expands and contracts in the width direction is obtained.

  For example, in Patent Document 1, a string-shaped portion composed of one or a plurality of warp knitting wales is alternately knitted by front and rear needle rows, and the binding yarn is a wale in which the ends of the front and rear string-shaped portions are opposed to each other. A warp knitted fabric in which the knitted fabrics are alternately knitted and engaged has been proposed, and when the warp knitted fabric is stretched in the width direction by increasing the distance between the front and rear needle rows, at least the distance between the needle rows. Only the part can be enlarged larger than the knitting width, and is intended for widening, and stretchability and designability are not expected.

  Moreover, in patent document 2, based on the basic technique of the said patent document 1, the structure | tissue of a string-like part is limited to a Denby knitting, and the connection structure | tissue between string-like parts is limited to a double chain knitting or a double denby knitting. The rib-shaped front ridges curved on the front side and the rib-shaped back ridges curved on the back side due to the curl phenomenon of the denby knitting forming the string-like portions are alternately arranged to form a corrugated plate shape in the width direction. Warp knitted fabrics having high stretch properties have been proposed.

The end of the front ridge and the end of the back ridge of the same warp knitted fabric are tightly connected by forming a stitch while reciprocating the ends with double chain knitting or double denby knitting. Denby knitting in the ridges is hindered from curving, and the denby knitting itself that forms the ridges tends to curl, but it has a loose knitting structure, so it has low power when stretched and is used for clothing. Depending on the weight, it cannot be expected to be durable due to its weight.

In the same warp knitted fabric, the colors of the front and back ridges are different, so that only the color of the front ridge is visible when contracted, and the color of the back ridge is the front when extended. Although it has a design property that can appear between stripes and visually recognize a vertical stripe pattern, since the connecting yarn is stitched at both ends of the front and back ridges, For example, if the color of the connecting yarn is the same as that of the front ridge, it will be one color of the front ridge when contracted, but at the time of extension, the color and back of the connecting ridge in the wal stitch row of the connecting portion. It becomes a color mixed with the color of the strip. On the other hand, in the opposite case, there is a problem that colors are mixed in the wale stitch row of the connecting portion at the time of contraction and the color effect is not clear.

Japanese Patent Laid-Open No. 01-148854 JP 2010-285721 A

  The problem to be solved by the present invention in view of the above-mentioned problems is to provide a rib warp knitted fabric suitable for clothes having excellent stretch-back properties and design properties.

In order to achieve the above object, the warp knitted fabric of the present invention is formed by integrating the ends of belt-like bodies knitted alternately in a plurality of wales by a front needle row and a back needle row of a double raschel machine with a connecting yarn. A rib warp knitted fabric having a corrugated plate shape due to the curl phenomenon of each belt-like body, and the integration by the connecting yarn is knitted only on the front needle row side and on the back needle row side It is formed by the intersection of sinker loops of connecting yarns that are only knitted.

  In addition, the knitted structure of the band-shaped body may be a half structure composed of Denby knitting and cord knitting.

  In addition, a mesh structure can be adopted as at least one of the knitted structure of the belt-shaped body formed by the front needle row and the knitted structure of the belt-shaped body formed of the back needle row.

Furthermore, the colors of the knitting yarn knitted with the front needle row and the knitting yarn knitted with the back needle row can be different.

  In the present invention, the integration by the connecting yarn is achieved by the intersection of the connecting yarn sinker loop knitted only on the front needle row side and the connecting yarn sinker loop knitted only on the back needle row side. Therefore, the belt-like body is curved to the maximum without being affected by the connecting part, and becomes a rib warp knitted fabric with excellent stretch-back properties. Since high stretch-back property can be obtained irrespective of the above, various knitting yarns can be used, and warp knitted fabric products having a texture and appearance that meet market demands can be provided.

Even if the colors of the knitting yarn knitted by the front needle row and the knitting yarn knitted by the back needle row are different, the connecting yarn is stitched by only one of the two needle rows, so the connecting portion There is no color mixing and a clear color effect can be exhibited.

In addition, since the knitted structure of the belt-like body of the present invention is a half knitted structure that is easy to curl with a tight knitted structure, a high power is obtained at the time of stretching, and the stretch-back property is maintained even after repeated use.

In addition, since the mesh structure is adopted for at least one of the knitted structure of the belt-like body by the front needle row and the knitted structure of the belt-like body by the back needle row, if both are meshed, the whole can be made to be air permeable. If only the needle row is made into a mesh structure, it can have air permeability when stretched, and various uses are possible.

It is a knitting structure figure showing one example of a rib warp knitted fabric of the present invention. It is the schematic which shows the cut surface which shows one Example of the rib warp knitted fabric of this invention. It is an organization chart showing one example of the rib warp knitted fabric of the present invention. It is an organization chart which shows one Example of the rib warp knitting of this invention which employ | adopted the mesh structure.

  In FIG. 1, reference numeral 1 denotes a rib warp knitted fabric which is an embodiment of the present invention, and the main knitted fabric is a belt-like body knitted alternately by a plurality of wales by a front needle row and a back needle row by a double raschel machine. 1 are warp knitted fabrics integrated with connecting yarns, and reference numerals f1 to f6 in FIG. 1 denote wales (stitch rows) knitted by a front needle row, and each wale is a warp knitted fabric. The strips 4 are integrated to form a band 4, and the reference numerals b1 to b6 are wales knitted by a back needle row to form the strip 5 in the same manner as described above, and the strips 4 and 5 are alternately arranged. The wales at the ends of the bodies 4 and 5 face each other at the same position.

  The end wales of the belts 4 and 5 have a chain knitting with the connecting yarn 2 or 3, and the chain knitting with the connecting yarn 2 is knitted only with the front needle row, while the chain knitting with the connecting yarn 3 is the back. The knitted needles are knitted only, and the chain knitting underlaps of the connecting yarn 2 and the chain knitting underlaps of the connecting yarn 3 are interlaced to connect each of the belt-like bodies 4 and 5 alternately. Being connected.

The connecting method applied to the warp knitted fabric of the present invention in which the front and back needles opposite to each other are connected by crossing the underlaps of the two chain stitches is a front side warp guide for supplying yarn to the front needle row. A front side intermediate warp guide bar and a back side intermediate warp guide bar are provided for connection between the bar group and the back side warp guide bar group that feeds the back needle row. In the next cycle, the connecting needle is fed to the back needle, and the other connecting thread is fed to the front needle with the back side intermediate warp guide rod, so that the two connecting threads cross the front side and the back side. Since the stitches are formed while being knitted, the respective underlaps are connected in an interlaced state.

  In FIG. 1, strips 4 and 5 indicate six rows of wales. However, strips formed by knitting two or more wales in each needle row may be arranged alternately. For example, strips The number of wales forming 4 may be alternately arranged in 4 rows and 8 rows, or normal double raschel fabrics that are stable in shape may be included between the alternating arrays or at both ends of the rib warp knitted fabric 1. .

  As shown in the cut surface of FIG. 2, the belt-like bodies 4 knitted by the front needle row are ribs 4a curved by winding a sinker loop inward due to a curl phenomenon peculiar to a single knitted fabric. 4b and 4c are formed, while the band-like body 5 knitted by the back needle row forms ribs 5a, 5b and 5c which are curved in opposite directions to form a corrugated cross section.

The warp knitting structure forming the strips 4 and 5 is not particularly limited as long as it is a structure that easily curls in the width direction, but if it is a half structure composed of a denby knitting and a cord knitting, the cord knitting is formed on the outermost layer opposite to the stitch side. Since there is a long underwrap, reduce the runner length (supply amount) of the cord knitting yarn, or use a crimped yarn or elastic yarn to apply a tensile force to the cord knitting underlap. This increases the curling force and provides a rib warp knitted fabric 1 with excellent stretch back properties, which is a preferred embodiment.

The rib warp knitted fabric 1 of the present invention is a connecting method by crossing underlaps, so the connecting part has little resistance to bending like a hinge, so it is easy to bend and deform due to the curl phenomenon, and stretch back For example, nylon fiber, polyester fiber, acrylic fiber, cotton, rayon, wool, silk, high-performance fiber, or those without any restriction on the knitting yarn to be used. Various yarns such as blended yarns can be used.

In addition, the curl phenomenon of a single warp knitted fabric is due to the stress that the knitting yarn bent by the formation of the stitches is trying to recover, so a high-rigidity knitting yarn is used to obtain high stretch-back properties. Preferably, for example, a yarn having a high single fiber fineness is selected, or the same fiber yarn can be twisted or resin processed to increase rigidity.

Further, the rib warp knitted fabric 1 of the present invention can make at least one of the knitted structure of the band-like body 4 by the front needle row and the knitted structure of the band-like body 5 by the back needle row into a mesh structure,
In particular, the belt-like body 4 by the front needle row is a normal warp knitted fabric, and the belt-like body 5 by the back needle row is made into a mesh structure, so that at the time of contraction, only the rib group by the belt-like body 4 of the normal warp knitted fabric is formed. However, since the belt-like body 5 having mesh holes appears from between the belt-like bodies 4 of the normal warp knitted fabric when stretched, the rib warp knitted fabric is stretched by intense exercise when applied to, for example, sports clothing. Only when it is pulled out, the mesh can appear and air permeability can be obtained.

  The mesh structure may be any structure that has a mesh hole and is easy to curl, such as a tulle mesh structure or an applied tissue thereof. In a more preferable aspect, the mesh structure also has design properties due to the shape and arrangement of the mesh hole. is there.

The present invention includes a rib warp knitted fabric 1 in which the colors of the knitting yarn of the belt-like body 4 knitted by the front needle row and the knitting yarn of the belt-like body 5 knitted by the back needle row are different. In some cases, only the color of the belt-like body 4 is visually recognized, and at the time of extension, the design effect that the colors of the belt-like body 4 and the color of the belt-like body 5 are clearly visually recognized as a striped pattern is exhibited.
That is, in the rib warp knitted fabric 1 of the present invention, the connecting yarn 2 is knitted only by the front needle row, the connecting yarn 3 is knitted only by the back needle row, and the connecting yarns 2 and 3 are straddled across both needle rows. Since the stitches are not formed, different colors of the connecting yarn are not mixed at either end of the belt-like body 4 or 5, and the striped pattern at the time of stretching can be clearly seen.

  Using a 24-gauge double raschel machine made by KARL MAYER, the rib warp knitted fabric of the present invention was knitted by the following method with the structure shown in FIG.

The band-like bodies 4 and 5 are composed of eight belt-like bodies 4 and 9 having a half structure of the front needle row at the warp guide rods L2 and L3 and a half structure of the back needle row at the warp guide rods L6 and L7. The strips 5 were alternately arranged, and the wales at the ends of the strips were opposed to each other.

Then, a single chain knit connecting yarn is arranged on the warp guides L4 and L5 at the needle positions of the wales facing each other, and the front side warp guide bar L4 is used as a yarn for feeding to the back needle row. The guide rod L5 is fed to the front needle row, and the ends of the belts 4 and 5 are connected by the intersection of the chain knitting underwrap by the warp guide rod L4 and the chain knitting underwrap by the warp guide rod L5. The warp knitted fabric 1 is connected to the rib warp knitted fabric 1 with a single chain knitting of the warp guide rod L4 and the single chain knitting of the warp guide rod L5 joined with an inserted structure of the warp guide rod L1. A waled ear tissue that does not curl was formed.

In addition, the yarn usage inserted into each warp guide is as shown in Table 1, the density of the knitting course is 29 courses / inch, and the obtained rib warp knitted fabric has two colors on the end wales of the strips 4 or 5 The strips 4 and 5 were clearly visible at the time of elongation, and excellent stretch-back properties were also confirmed.

  As a result of knitting the rib warp knitted fabric of the present invention in the organization chart shown in FIG. 4 in which a mesh structure is adopted for the belt-like body 5 with respect to the rib warp knitted fabric of Example 1, the result is the same as the rib warp knitted fabric of Example 1. The stretch-back property is excellent, and a clear striped pattern due to the different colors of the belt-like bodies 4 and 5 at the time of stretching is visible, and at the same time, it can be confirmed that the warp knitted fabric has both air permeability and design by mesh fabric. .

  In Example 2, the connecting yarns knitted on the mesh structure side of the band-like body 5 are warp yarn guides L4 and L5 for the purpose of making the structure of the connecting yarn knitted on the left and right sides of the belt-like bodies 4 and 5 symmetrical. On the other hand, the connecting yarn knitted on the belt-like body 4 side is inserted into the warp guides L6 and L7 separately, the ear tissue is changed to a double denby knitting with the warp guides L3 and L8, and the thread use of each element is an example. Same as 1.

It has a design that exhibits a vivid color effect, so it can be applied to clothing, etc.Furthermore, by adopting a mesh fabric, breathability can also be given, so sports clothes that move rapidly It becomes a suitable material.
