Description

  The present invention relates to a warp knitted fabric mainly used for apparel products, and more particularly to a warp knitted fabric knitted using a warp knitting machine equipped with a jacquard tack and a manufacturing method thereof.

  Conventionally, it is known to knit a warp knitted fabric having a pattern using a warp knitting machine having a heel having a jacquard function (hereinafter referred to as a jacquard heel).

  For example, in Patent Document 1, in a method of forming a pattern using a warp knitting machine using Jacquard, a pattern is obtained by wrapping a yarn having a color different from or different from that of the ground knitting, and wrapping it. And a method of performing knitting that is hidden in the knitting without wrapping in portions other than patterning is disclosed.

  Further, in Patent Document 2, knitting is performed using a Raschel machine equipped with one handle hook and three ground hooks, the front hook and the middle hook form a ground structure, and the handle yarn is inserted on the surface thereof. A knitted fabric is disclosed in which a pattern is formed and a back knitting yarn is inserted on the back surface to form a back pattern.

  Further, Patent Document 3 discloses a three-dimensional molded product that is manufactured by a double raschel machine and has a pattern formed by a combination of a convex portion formed by a loop formed by connecting yarn stitches and a concave portion by insertion, and a knitting method thereof. ing.

  However, in the methods of Patent Documents 1 to 3, the knitted fabric is thicker and heavier. In the pattern expression (color difference expression) due to the color difference of the knitting yarn at the time of pattern formation, the knitting is performed by knitting with other knitting yarns. Different colors were mixed on the ground, and the pattern was blurred.

  Further, Patent Document 4 discloses a raschel knitted fabric having a braided structure that is knitted by engaging a stitch of a base fabric structure with a loop of a tack warp, and describes that the form is stabilized by adding an insertion yarn. However, there is no mention of pattern formation using this.

  Patent Document 5 describes a knitted fabric knitted by a Raschel knitting machine using three pieces of ground cloth, which stabilizes the warp insertion yarn by sandwiching it with the ground yarn, and determines the exposed area of the warp insertion yarn by the way of knitting the ground yarn. Although it is disclosed that it can be adjusted, it is possible to adjust the exposed area of the warp insertion thread at a constant ratio as a whole, but it is impossible to form a complicated pattern.

  Next, embodiments of the present invention will be described with reference to the drawings.

  The warp knitted fabric of the present invention includes a double raschel machine having two rows of needles illustrated in FIG. 1, which has two rows of needles in the front and rear and a jacquard rod whose lateral movement is controlled by a jacquard device. Alternatively, the needle row is knitted by a warp knitting machine such as a single raschel machine. Here, “lateral swing” means underlap in the knitting width direction. In the following description, the case where it is manufactured by knitting with a double Russell machine will be described as an example.

  In FIG. 1, N1 and N2 are front and rear needle rows arranged in parallel in the knitting machine width direction, T1 and T2 are front and rear needle hooks (trick plates), and L1 to L6 are hooks used for knitting, respectively. Of these, L1, L2, L5, and L6 are grounds for knitting a chain structure or an inserted tissue in the ground tissue, and L3 and L4 are jacquard baskets. One warp knitted fabric A1 is knitted by the front needle row N1 with the heel L1 to L3, and the same warp knitted fabric A2 is knitted with the rear needle row N2 by the heel L4 to L6. At this time, out of the cages (ground rods) L1, L2, L5, and L6 for knitting the ground tissue, L1 and L6 can be used for knitting the inserted tissue, and L2 and L5 can be used for knitting the chain tissue. In addition, L2 and L5 can be used as wrinkles for knitting insertion tissues, and L1 and L6 can be used as wrinkles for forming chain structures. Y1 to Y6 indicate knitting yarns threaded through the guide portions G1 to G6 of the respective ridges L1 to L6, and B1 to B6 indicate beams of the respective knitting yarns.

  The front and back warp knitted fabrics A1 and A2 are knitted by the heels L1 to L3 and the heels L4 to L6. The front and back warp knitted fabrics A1 and A2 can be knitted so as to be separable. The warp knitted fabric A1 is the front body of the clothing product, the warp knitted fabric A2 by the collars L4 to L6 is the back body of the clothing product, and the front and back warp knitted fabrics A1, A2 are connected at the required locations to form a cylinder. The warp knitted fabric can be knitted continuously.

  The present invention relates to the warp knitted fabric knitted by the heels L1 to L3 and / or the heels L4 to L6 as described above and a method for manufacturing the same, and has the following characteristics.

  The warp knitted fabric of the present invention is knitted with a structure as shown in FIG. 2A, for example, using at least three ridges L1 to L3 and / or L4 to L6 including one jacquard ridge L3 or L4. .

  Based on FIG. 2A, an example of the knitting organization and the knitting state by the three ridges L1 to L3 and / or L4 to L6 will be described, but the present invention is not limited to the following examples.

  Of the three ridges L1 to L3 (L4 to L6), the ridges (ground fences) L1 and L2 (L6 and L5) knit the chain structure and the insertion structure of the ground structure over the entire knitted fabric. That is, the knitting yarn for ground knitting is introduced by the heel L2 (L5), and the chain structure is knitted, and the insertion yarn is knitted to the heel L1 (L6).

  Then, in the plain part without a pattern, as shown in FIG. 2A (a), the jacquard knitting yarn is introduced by the jacquard rod L3 (L4), and the lateral swing width is made constant with respect to the ground structure. As shown in Fig. 2A (b), the jacquard L3 (L4) is oscillated appropriately by jacquard control according to the pattern and product pattern. While knitting while changing the width, it is knitted with a structure that forms an opening at a required location corresponding to the pattern or product pattern as described later.

  That is, the jacquard structure by the jacquard ridge L3 (L4) is, for example, with a 1 × 1 denbi structure in which stitches are alternately formed in adjacent wells as a basic structure, and the lateral swing width is appropriately changed by jacquard control. A 1 × 2 cord structure that forms a stitch loop over three wells and a chain structure that forms a stitch loop in the same well are appropriately combined to form a pattern ( Jacquard pattern).

  The present invention uses the above-mentioned jacquard structure. For example, in a portion that does not represent a color difference, such as a plain portion, a denbi structure as shown in FIG. 2A (FIG. 4A, FIG. 4C, FIG. 4D) described later. (Thin) or 1 × 2 cord structure (thick) as shown in FIG. 4B. Alternatively, the denby structure and the cord structure are combined so as not to form an opening (hole) (not shown).

  In addition, as shown in FIG. 2A (b), the pattern portion that expresses the color difference in the pattern portion is a chain structure (hole) at the required location according to the pattern and product pattern, and this chain structure and A knitted structure (thin fabric) and / or a cord organization (thick fabric) is appropriately combined and knitted to form a handle and to form an opening 2 by a hole in the chain structure. Thereby, in the said opening part 2, the thread | yarn (insert thread) of the said insertion tissue can be exposed so that visual recognition is possible.

  That is, in the knitting structure, with respect to the insertion structure by the insertion yarn guided by the ridge (ground) L1 (L6), for example, as shown in FIG. By inserting and swinging so as to be alternately positioned, the insertion thread 3 is visibly exposed on the side surface of the well W that defines the opening in the opening 2 portion of the chain structure.

  Therefore, the insertion yarn 3 knitted by one of the collars L1, L2 (L6, L5) is different in color or dyeing from the other knitting yarns other than the insertion thread. By using the thread, the insertion thread 3 is formed from the side surface of the opening 2, that is, from the side surface of the well W that defines the opening 2, in the opening 2 of the hole structure by the chain structure of the jacquard structure as described above. Is exposed, the insertion yarn 3 having a color different from that of the other knitting yarns can be visually recognized from the front side, so that the color difference viewed from the front side can be expressed in the portion expressing the pattern.

  Since the opening 2 is formed by making the jacquard structure into a chain structure, when the chain structure is lengthened, the opening part is also opened longer and larger, so that a large amount of the insertion thread 3 is exposed. Therefore, the color of the insertion thread can be visually recognized darkly.

  The chain structure formed by the jacquard ribs L3 (L4) that form the opening 2 is usually continuous over 1 to 100 courses. Preferably, it shall be continuous over 1 to 80 courses. When it is continued over 100 courses, it becomes easy to hook the knitting yarn when used as a warp knitted product, and the dimensional stability is deteriorated.

  In addition, the insertion ratio of the insertion yarn in the knitting width direction by the collar (ground) L1 (L6), that is, the ratio of the insertion yarn to the loop is 30 to 100%. Specifically, the case of FIG. 2A is 100%, the case where the insertion thread is inserted into every other well W as shown in FIG. 2B is 50%, and the insertion thread is inserted every two wells as shown in FIG. 2C. The case of inserting into the well W is 33%. The insertion thread may be inserted regularly as shown in the figure, or may be randomly inserted as long as the ratio is within the above range. When the insertion ratio is less than 30%, the dimensional stability is deteriorated, and the color of the insertion thread is difficult to visually recognize.

  The insertion yarn can be inserted into 1 to 5 wells by swinging in the weft direction (knitting width direction). That is, on the knitting, the heel L1 (L6) for knitting the insertion yarn is appropriately inserted by being underwrapped from 1 to 5 needles. When underlap is applied to 6 or more needles and inserted into 6 or more wells, the insertion yarns overlap, and the knitted fabric tends to be thick, heavy and hard. Preferably, the underlap is repeated for one or two needles. FIG. 3A shows a case where a course is inserted into two wells per course.

  Furthermore, the horizontal swing width of the insertion yarn is not necessarily constant for each course, and an insertion structure in which the swing width of the underlap is changed in a required course as shown in the example of FIG. In addition, as shown in FIG. 2A, the insertion structure of the insertion thread is inserted so that it traverses the well every course as shown in FIG. 2A, or every 2 courses as shown in FIG. 4C, or every 3 courses. You can also insert it. The same applies to the case where the horizontal insertion is performed over a plurality of wells. This is schematically shown in FIG. 3B, in which the reference numeral 3 indicates an insertion thread and the reference numeral 4 indicates a chain stitch loop. It is preferable that the insertion yarn 3 is appropriately inserted every 1 course to 5 courses (not shown) in the warp direction (length direction) as shown in the figure. More preferably, it is every 1 to 3 courses. That is, if the interval of every 6 courses or more is set, the exposure of the insertion yarn becomes longer, which may cause the knitting yarn (insertion yarn) to be easily hooked when used as a product, or may deteriorate the dimensional stability. is there.

  4A, FIG. 4B, FIG. 4C, and FIG. 4D show an example of a knitted fabric of a plain portion that does not represent a color difference in the warp knitted fabric of the present invention described above, with the wrapping states of the ridges L1 to L6 broken down Yes. In FIG. 4A, the knitting by the jacquard heels L3 and L4 is a denbi structure, and the knitting by the heel (one of the ground) L1 and L6 is inserted into the same well while being swayed for each course. The other is that the knitting by L2 and L5 is a chain structure. In FIG. 4B, the knitting by the heels L1, L6 and L2, L5 is the same as that in FIG. 4A, and the knitting by the jacquard heels L3, L4 is a 1 × 2 code organization. In FIG. 4C, the knitting by Jacquard 筬 L3 and L4 is a denbi structure, the knitting by 筬 L2 and L5 is a chain structure, and in particular, the knitting by 筬 L1 and L6 is laterally swung to the same well every two courses. Insert tissue to be inserted. In FIG. 4D, knitting with jacquard 筬 L3, L4 and 筬 L2, L5 is performed in the same manner as in FIG. This shows a case where an insertion tissue in which the horizontal swing width is changed for each course and the horizontal insert is inserted over three wells is shown.

  In any of these cases, since the structure of the jacquard ridges L3 and L4 is a denbi structure and / or a cord structure, the insertion thread is hidden in the ground structure. For example, if the insertion yarn is yellow and the knitting yarn other than the insertion yarn is brown, the insertion yarn (yellow) is hidden in the ground texture (brown), so the knitted warp knitted fabric is the color of the ground texture (brown) Will be visually recognized.

  5A and 5B show an example of the knitting structure of the pattern portion expressing the color difference in the warp knitted fabric of the present invention described above, in an exploded manner of the wrapping states of the ridges L1 to L6. In FIG. 5A, the knitting by the heels L1, L6 and L2, L5 is the same as in FIG. 4A, and the knitting by the jacquard heels L3, L4 is made into a chain structure with a required course based on the denbi structure. Further, in FIG. 5B, the knitting with the heels L2 and L5 and the jacquard heels L3 and L4 are the same as in FIG. Have an organization.

  Thereby, the structure (hole) having the opening is appropriately knitted, and the insertion thread can be visually recognized from the opening by the hole of the chain structure as described above. If the other knitting yarn is brown, the yellow color due to the insertion yarn can be visually recognized in the brown color due to the other knitting yarn in the opening, and as a result, the portion of the tissue having the opening is expressed with a color difference. .

  In this way, by using a knitted chain structure, denbi structure, 1 × 2 cord structure knitted by a jacquard kite, and an insertion structure by using an insertion thread different in color from other knitting yarns, a color difference is created at the opening of the jacquard structure. By combining this with the arrangement and length of the openings, an elegant design with unprecedented design can be formed.

  In the knitting of the knitting structure having the above-described configuration, the heel L1 (L6) that guides the insertion yarn and knitting the insertion structure is under-wrapped behind the knitting needle, thereby inserting the insertion yarn of the heel L1 (L6). Is inserted and locked in a shape sandwiched between a needle loop and a sinker loop of a chain knitting yarn of the collar L2 (L5) at a portion crossing the well. For example, in the case of knitting that overlaps yarns of a certain color, the insertion structure that underwraps as described above, although it becomes a blurred color overall by knitting with other knitting yarns of different colors Then, since the color of the insertion yarn can be visually recognized at the opening as described above without knitting with different-colored knitting yarns of other tissues, a clear color difference expression is possible.

  In addition, the insertion structure reduces the amount of use of the knitting yarn because the knitting yarn does not come out on the front side of the fabric compared to the overlapping knitting, so that a knitted fabric in which the fabric does not become thick and heavy can be obtained. Further, since the insertion yarn is hardly exposed on the surface of the knitted fabric other than the opening, in use as a warp knitting product such as clothing, the insertion yarn is rarely in contact with the skin surface, and the texture is not impaired.

  In addition, since the insertion yarn has a role of controlling the stretch by strengthening the loop connection in the warp direction (knitting direction), the knitting yarn is knitted against the tension during knitting of the knitted fabric or during processing such as heat setting or dyeing. It will stabilize the ground. Therefore, the dimensional stability at the time of finishing the product is excellent, the knitted fabric is less likely to be skewed and curved, and the yield is improved. Also, the burst strength is improved. In addition, in the case of an insertion structure in which the insertion yarn is swung into a plurality of wells, it also serves to connect the chain stitches of the ground structure.

  As for the above color difference expression, as described above, the interstitial yarn that can be dyed with different dyes (for example, acid dye and cationic dye) is used for the insertion yarn and the knitting yarn other than the insertion yarn. By performing post-dyeing of dyeing with a dye (for example, a cationic dye) capable of dyeing an insertion yarn after knitting and dyeing with a dye (for example, an acid dye) capable of dyeing a knitting yarn other than the insertion yarn, The insertion yarn and the knitting yarn other than the insertion yarn can be dyed separately for each color, thereby enabling color difference expression in the warp knitted fabric.

  In addition, it is also possible to express a color difference on a warp knitted fabric by using different colors of original yarn or dyed yarn for either or both of the insertion yarn and the knitting yarn other than the insertion yarn.

  The fiber material constituting the knitting yarn used for knitting is not particularly limited. For example, synthetic fibers such as polyester, polyamide, acrylic and vinylon, semi-synthetic fibers such as acetate and triacetate, and regenerated fibers such as rayon and cupra. , Natural fibers such as cotton, wool, silk and the like, and two or more of these may be combined. Of these, polyester and polyamide are preferred.

  The type of knitting yarn is not particularly limited, and examples thereof include spun yarn, processed yarn, monofilament yarn, filament yarn, and the like, and processed yarn is preferable. Further, functional yarns such as heat retaining yarns and antistatic yarns and design yarns such as lame yarns may be used as the insertion yarns.

  Moreover, it is preferable that the knitting yarn for jacquard structure knitted by the jacquard ridge is a polyurethane elastic yarn or a covering yarn using the same. The stability and strength performance of the fabric can be improved by using an elastic yarn such as a polyurethane elastic yarn or a covering yarn using the polyurethane elastic yarn. Moreover, when making it into a garment product, the expansion and contraction is good and the feeling of fitting when worn is also good.

  What is necessary is just to select suitably the fineness of the knitting yarn used for knitting in the range of 22 dtex-330 dtex.

  The warp knitted fabric produced according to the present invention may be subjected to functional processing such as deodorization processing and sweat absorption processing, various types of printing processing, and raising processing as necessary.

  The knitting structure and the knitting method described above can also be applied to a warp knitted fabric in which the front and back warp knitted fabrics having a jacquard structure are connected and knitted continuously in the knitting direction to form a tubular shape.

  That is, in the knitting by the double raschel machine equipped with the jacquard reeds, the warp knitted fabric by the reeds L1 to L3 is used as the front body of the clothing product, and the warp knitted fabric by the reeds L4 to L6 is used as the back body of the clothing product. A cylindrical warp knitted fabric that has been connected to form a cylinder is continuously knitted. As shown in FIG. 6, the tubular warp knitted fabric is formed by continuously knitting a tubular portion 5 having a predetermined length corresponding to a product pattern such as clothing in the knitting direction with the product pattern as one unit. Yes, both the front and back warp knitted fabrics form the front and back of the tubular portion 5. Reference numeral 6 in the figure denotes a front / back connecting portion that also serves as an outline of the product pattern, and reference numeral 7 denotes a front / back connecting portion between the cylindrical portions 5 and 5.

  As described above, a cylindrical warp knitted fabric is formed by continuously knitting a cylindrical portion of a certain length according to the product pattern by connecting the ground structure to a chain structure and an insertion structure. In this case, since the line to be cut is clear, it is easy to cut along the product pattern.

Measure the length to the mark with the load applied after 60 minutes (A), remove the load and measure the length to the mark after 30 seconds (B), leave it for 60 minutes, The length is measured (C).
The elongation recovery rate is calculated by the following formula.
Recovery rate after 30 seconds = (A−B) / (A−20) × 100
Recovery rate after 60 minutes = (A−C) / (A−20) × 100

(Declination)
Two lines DE and FG perpendicular to the knitting end (well line) are drawn in advance on the sample (about 30 mm × about 30 mm) before washing.
Wash according to JIS L 0217-103.
In the sample after washing, a line is drawn along the well line from approximately the center A point of the line DE, and a point that intersects the line FG is defined as a B point.
A line is drawn perpendicularly to the line FG from the point A, and a point that intersects the line FG is defined as a point C.
The skew degree is calculated by the following formula.
Skew degree = BC (mm) / AB (mm) × 100
It can be said that the smaller the dimensional change rate, the better the extension recovery rate (higher recovery rate), and the lower the skewing rate, the better the yield.
