Even if one of the ground yarns constituting the tuft part is frayed, the other yarn is prevented from fraying, for example, by crossing the yarns in each place or alternately forming stitches for every other course. Exhibits a wedge effect. Even when the elastic yarn is knitted in the warp knitted lace fabric, the knitting of the insert knitting in the tuft portion prevents fraying, and a stable tuft can be obtained.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an anti-raveling structure for a tuft in a warp knitted lace fabric.

[0002]

[Prior art]

 Conventionally, the changing net effect of large and small mesh structures has been required for the ground of warp knitted lace fabrics for clothing such as shawls, outerwear and innerwear. A chain knitting in which the ground yarn acts on one knitting needle is optimal for the ground structure for forming the gland of the change net.

[0003]

[Problems to be solved by the device]

 However, if the chain knitting is used to form the tufts of the warp knitted lace fabric, the cut chain knitting tends to fray in the starting direction from the cut point when the tassel is cut in the finishing process. Therefore, there is a problem in terms of quality, and especially in elastic warp knitted lace fabrics in which elastic yarns are inserted, the chain knitting tends to become loose due to the expansion and contraction of the elastic yarns, so that the chain knitting is significantly frayed. However, deterioration of quality was inevitable during washing.

In order to solve the above-mentioned problems, a method has already been known in which a chain knitting forming a tufted portion is provided with a dense portion for driving, and the portion is cut to prevent fraying ( Japanese Utility Model Publication No. 57-4154). The method relates to a plain double-sided warp knitted fabric knitted by a double Raschel machine, not to a warp knitted lace fabric, and the tuft of the plain double-sided warp knitted fabric avoids changes in texture due to increase or decrease in the shot density. However, a densely packed portion is uniformly formed in the width direction of the tuft.

Therefore, if it is attempted to form the root of the tuft by shifting the position in the knitting direction of the warp knitted fabric, a densely-punched portion will also be formed in the fabric main body of the warp knitted fabric, so that it actually occurs. Was impossible. In addition, since a driving density conversion device is required to form a densely packed portion even when forming a normal tuft, the manufacturing cost of the knitting machine is high, and the driving density conversion device does not have a dense driving density. The work to set various parts is also necessary and has not been realized until now. An object of the present invention is to provide a structure for preventing fraying of a tuft in a warp knitted lace fabric that can solve the above problems.

[0006]

[Means and Actions for Solving the Problems]

 In a warp knitted lace fabric comprising a main body portion and a tuft portion connected to the main body portion, the ground yarns forming each tuft portion are at least two of the ground yarns constituting the main body portion, and It is configured to form a stitch, which causes some external force to be applied to the tufts during use, so that even if one of the ground yarns forming the tufts is pulled in the direction of knitting, other fabric The thread exerts a wedge action and effectively prevents fraying.

Since the ground yarns forming the tufts cross each other to form a stitch row, an external force is applied to one of the ground yarns forming the tufts, and when one tries to fray in the knitting start direction, this Other yarns that intersect with the yarns are caught up, and the progress of the fraying is suppressed by the entanglement in the stitches that the yarn itself composes.

By forming the stitch rows by alternately forming the stitches of the ground yarns forming the tufts in every alternate course, an external force is applied to one of the yarns constituting the tufts, and the knitting start direction is increased. When a fray is attempted, this ground yarn is caught in and entangled with the stitches of another ground yarn that is forming a stitch in the next course, and the progress of the fray is stopped.

Since the elastic yarn is knitted by the insertion knitting in the stitch row forming the tuft portion, even if the elastic yarn has a fraying action in the tuft portion due to the stretching force of the elastic yarn, two ground fabrics are knitted. Due to the mutual anti-fraying action of the threads, the elastic threads are stably held in the tufts and the shape of the tufts is not destroyed.

【Example】

 The present invention will be described below with reference to the drawings. FIG. 1 is a knitting organization diagram of an embodiment of a fray stop preventing structure of a tuft in a warp knitting lace fabric of the present invention, and FIG. 2 is an example of a warp knitting lace fabric having a tuft knitted by the organization of FIG. 1 or 3. Fig. 3 is a plan view showing an overview of Fig. 3, Fig. 3 is a knitting organization diagram of another embodiment of the fray-stopping structure of the present invention, and Fig. 4 is an overview of an example of a warp knitted lace fabric having a tuft knitted with the organization of Fig. 3. FIG. 5 is a plan view showing various shapes of the warp knitted lace fabric with a tuft having the anti-raveling structure of the present invention. Black dots in FIGS. 1 and 3 represent the position of the knitting needle in each knitting course.

1 and 2 of FIG. 1, which is a knitting organization chart of a warp knitted race place according to one embodiment of the present invention, are 1-in-1-out and 1-out-1-in in a race Raschel machine manufactured by Carl Meyer Co., Ltd., respectively. The ground thread passed through the reed L1 and the ground reed L2 (both not shown) is shown. In the area A, the ground yarn 1 and the ground yarn 2 each knit a chain knit, and together with the jacquard yarn and the handle yarn (both not shown) form the main body of the warp knitted lace fabric 3. In the area B, the ground yarn 1 and the ground yarn 2 are knitted so that the 1 × 1 tricot structures intersect each other to form a stitch row of the tufts of the warp knitted lace fabric 3. In the area C, each of the ground yarn 1 and the ground yarn 2 again knits a chain knitting for several courses to form a stitch row of the cut margin portion of the tuft portion.

The knitted warp knitted lace fabric 3 is cut in the width direction along the line X-X in the center of the area C in the post-process, and is cut into the main body 4 as shown in FIG. A unit of warp knitted lace fabric 30 having a tuft 5 is produced. In the areas B and C, the jacquard thread and the pattern thread are knitted with an insertion structure that does not connect the stitch rows.

Since the tuft portion 5 is knitted by the ground yarn 1 and the ground yarn 2 so as to intersect each other in a 1 × 1 tricot structure, for example, even if the stitch knitted by the ground yarn 1 is likely to be frayed, Since the stitches knitted by the ground yarn 2 are hard to stop, the phenomenon of fraying in the knitting start direction of the arrow F from the cut ends d1, d2 ... dn of the tuft portion 5 is prevented. It should be noted that the direction of overlapping of the ground yarn 1 should be such that the relationship between the ground yarn knitted with the overlapping fabric and the jacquard yarn or the handle yarn knitted with the insertion fabric is a direct hook in each knitting course. The direction of over-lapping of the ground yarn 2 is always in the same direction.

6 and 7 of FIG. 3 showing another embodiment of the present invention, in a race Raschel machine manufactured by KARL MAYER, each of the ground reed L1 and the ground reed L2 (both not shown) is fully threaded. Shows the ground yarn. The ground yarns 6 and 7 are knitted in a links knitting structure that alternately overlaps every other course, and together with the jacquard yarn and the pattern yarn (both not shown), the main body of the warp knitted lace fabric 3-1. It forms parts and tufts. In the tress, the jacquard yarn and the handle yarn are woven with an insertion structure that does not connect the stitch rows.

A warp knitted race having a tufted portion 5 and a main body portion 4 as shown in FIG. 2 by cutting the tufted portion of the warp knitted race ground knitted with the ground yarn 6 and the ground yarn 7 at the center. When the base 30 is manufactured, the tufted portion 5 is knitted with the links knitting structure by the ground yarn 6 and the ground yarn 7. Therefore, even if a fray is generated in the stitch knitted by the ground yarn 6, Since the knitted stitches are hard to stop, the phenomenon of fraying in the knitting start direction of the arrow F from the cut ends d1, d2 ... dn of the tuft portion 5 is prevented. It should be noted that the overlapping of the ground yarn 6 should be performed so that the relationship between the ground yarn knitted with the overlapping fabric and the jacquard yarn or the handle yarn knitted with the insertion fabric is a direct hook in each knitting course. The direction of overlapping of the ground yarn 7 with respect to the direction is always opposite.

The ground yarns 8-1, 8-2 ... 8-n are examples of the knitting structure of each of the n jacquard yarns forming the warp knitted lace fabric 3-1 together with the ground yarn 6 and the ground yarn 7. is there. Ground yarns 8-1, 8-2 ... 8-n are knitted with an insertion structure that does not connect each stitch row, and the roots of the tufts are displaced in the knitting direction in the areas D and E. As a result, the warp knitted lace fabric 30-1 having the main body portion 9 and the tuft portion 10 is manufactured as illustrated in FIG.

The warp knitted lace fabric 30-1 is cut by the YY line and the ZZ line along the center points of the area D and the area E in the post-process.

As shown in FIG. 5, a garment 13 such as a shawl having a tufted portion 12 formed by shifting the root in the knitting direction is manufactured. By the structure similar to the above, the respective garments 14, 15, 16 such as shawls having the tassel portions 121, 122, 123 which can freely incline or meander with respect to the knitting direction are manufactured. .

The tufts 12, 121, 122, 123 are knitted with the ground yarn 6 and the ground yarn 7 in a links braid, so that even if the stitches knitted with the ground yarn 6 are frayed, Since the stitches knitted by the yarn 7 are hard to be stopped, the phenomenon of fraying in the knitting start direction from the cut ends of each of the tassels 12, 121, 122, 123 is prevented.

In the knitting structure diagram of FIG. 1, the ground yarn 1 and the ground yarn 2 do not necessarily have to intersect each course in the area B forming the tuft portion, and the cut margin portion is formed. The area C does not necessarily have to be formed.

Further, since the stitch row of the main body portion of the warp knitted lace fabric knitted with the ground yarn 6 and the ground yarn 7 of FIG. 3 has a fray-stopping structure like the tuft portion, a cut of the main body portion, When sewing is performed, the phenomenon of fraying from the cut end of the main body in the knitting start direction is prevented.

Due to the structure of the warp knitted lace fabric 3 and the warp knitted lace fabric 3-1, the stitch row knitted with the ground yarn 1 and the ground yarn 2 in FIG. 1 and the ground yarn 6 and the ground yarn 7 in FIG. Even when a yarn (not shown) is knitted with the insertion structure knitted in one stitch row, the chain knitting of the tufts 5 and 10 does not occur due to the expansion and contraction of the elastic yarn.

[0023]

[Effect of device]

 According to the structure for preventing fraying of the tufts in the warp knitted lace fabric of the present invention, it is possible to prevent the phenomenon of fraying from the cut end of the tufts in the knitting start direction. It is possible to manufacture a warp knitted lace fabric having a tufted portion, or a warp knitted raced fabric having a tufted portion of any shape such that the root of the tufted portion is inclined or meanders in the knitting direction. This solves the problem that the tassels tend to fray in the knitting start direction in conventional clothing such as shawls, outerwear, and innerwear. Further, even in the elastic warp knitted fabric in which the elastic yarn is knitted with the insertion structure, the occurrence of the fraying is similarly eliminated, so that the deterioration of the quality at the time of washing can be prevented. Therefore, it is possible to prevent the phenomenon of fraying in the direction to start knitting from the cut end of the main body of the warp knitted lace fabric with the tufted portion, and with the tufted portion having various decorative effects due to sewing work and the like. Will be able to freely create clothing and other items.
