Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for producing warp-knitted lace without running.

(Prior technology) As a knitted fabric that does not produce runs,
This publication discloses a fabric in which two types of yarns with different softening points are twisted or aligned and knitted, and only the intersections of the yarns with low softening points are fused together. In addition, in Japanese Utility Model Publication No. 55-176389, a thermal adhesive yarn and a regular yarn are combined to form a warp, a chain stitch is knitted with this warp, and the bonded portion between the warp and the swing yarn is made of a thermal adhesive yarn. A warp-knit lace fabric bonded by melting is disclosed. In addition, Japanese Patent Application Laid-Open Nos. 60-39458 and 60-65162 disclose warp-knitted lace fabrics in which the warp yarns constituting the chain stitch are knitted while reciprocating between a plurality of wales;
That is, a method is disclosed in which the warp yarns knit several courses of chain stitch in one wale, then move to an adjacent wale, and knit this adjacent wale.

(Problems to be solved by the invention) Publication of Utility Model Publication No. 47-20306 and Publication of Utility Model Application No. 55-
As described in Japanese Patent No. 176389, low softening point yarns or heat-adhesive yarns are knitted by aligning or doubling with other yarns, and then heat-sealed to normal yarns. Alternatively, the heat-adhesive yarn adheres to the entire surface and the texture becomes hard, so it cannot be used for warp-knitted lace fabrics that require a flexible texture. Ranks were generated immediately when the threads were cut.

On the other hand, JP-A-60-39458 and JP-A-60
- As described in Publication No. 65162, the warp threads are traversed between adjacent wales, which has the problem of difficulty in obtaining the desired pattern as a warp-knitted lace, such as the limitations on knitting large hole structures. It was hot.

The present invention provides a warp-knitted lace that does not generate runs, has a soft texture, is easy to dye, and can have any desired pattern.

(Means for solving the problem) In Fig. 1, many chain stitches 7 are arranged in parallel.
and a ground thread insertion thread (not shown) and pattern thread (not shown) that connect these chain stitches 1.
When knitting a warp-knitted lace consisting of, etc., the above-mentioned chain stitch 1 is combined with a first yarn 2 made of ordinary fibers,
All wales and all courses are knitted using heat-adhesive yarns 3p formed by providing a low melting point synthetic resin layer on the surface of second yarns 3 made of ordinary fibers.
However, the above-mentioned first yarn 2 and thermal adhesive yarn 3
1 on one side of p (thermally adhesive yarn 3p in the example shown)
Only the main wale is knitted, and the other (first yarn 2 in the example shown) is made to reciprocate between a plurality of wales and knit a plurality of courses in each wale. Then, by heat treatment after knitting, the synthetic resin layer of the heat-adhesive threads 3p is melted, and the contact portions of the heat-adhesive threads are bonded together.

(Function) Since the heat-adhesive yarn 3p is the ordinary second thread 3 provided with a low-melting point synthetic resin layer, even after the low-melting point synthetic resin layer is melted, the heat-adhesive yarn 3p The normal second yarn 3 that constitutes the core of 3p remains in the lace ground. In other words, even after the synthetic resin layer on the surface of the heat-adhesive yarn 3p moves due to the fusing treatment and the subsequent finishing process, all of the multiple chain stitches 1 remain as the normal first yarn 2 and It is composed of two second threads 3. Therefore, when sewing, the first thread 2 or the second thread in the chain stitch
Even when one of the yarns 3 is cut, the other remains, so that even when the fused portion is peeled off, runs are prevented, and the chain stitch 1 maintains an uninterrupted appearance. Moreover, when both the first yarn 2 and the second yarn 3 are cut, run is prevented at the fused portion. Even if both the first yarn 2 and the second yarn 3 are cut and a strong external force acts to peel off the fused portion, the first yarn 2 and the second yarn 3 3
One of the two knits only one wale, and the other knits multiple courses of yarn and double chain stitch in each wale while going back and forth between multiple wales, so a run occurs temporarily. Even in this case, the run stops at the part where the other yarn moves through the wale, and there is no influence beyond that point.

Note that the other thread 2, which knits a chain stitch by reciprocating between a plurality of wales, is thinner than one thread (second thread 3), which knits only one wale 1.
When a yarn of denier or less is used, the transition portion 2a from one wale to the other is not visually noticeable. Furthermore, when the tension of the other yarn 2 is set to be lower than the one yarn tension 3,
Since the transition portion 2a described above becomes more conspicuous, it becomes easier to form large holes such as net-like holes. In addition, the number of courses in which the other yarn 2 continuously knits a chain stitch with one yarn 3 in one way is as follows:
4 to 20 courses is preferable; if it is less than 3 courses, it becomes difficult to form a net, and if it is more than 21 courses, the run becomes long when two yarns are cut, which is not preferable. In addition, the synthetic resin layer is made of nylon 6, nylon
When made of copolymerized nylon of 66 and nylon 12, it is easy to coat nylon yarn, which is most often used as the second yarn for lace, and has almost the same dyeability, making finishing processing easy. Become. In this case, the amount of solid content adhered to the second yarn 3 is 1 to 30%, and if it is less than 1%, there is almost no effect, and if it exceeds 30%, the texture becomes hard. Particularly when the application is for inner wear, it is preferably 7% or less. Additionally, stretchable elastic threads can be inserted into each wale to give the lace elasticity. Ordinary chain stitches become more prone to unraveling when they are imparted with elasticity, but the lace obtained with this invention does not fray, so there is no problem even if stretchable elastic yarn is inserted to impart elasticity. It is. It goes without saying that the second yarn 2 may be used as one yarn, and the heat-adhesive yarn 3p may be used as the other yarn.

(Example) A 20 denier nylon multifilament yarn is used as the first yarn 2, a 15 denier nylon multifilament yarn is used as the second yarn 3, and the second yarn 3 is made of nylon 6, nylon 66 A low melting point synthetic resin layer (melting point 120°C) made of a copolymer of The second adhesive yarn 3p
The vertical lace shown in the figure was knitted. That is, along with the first yarn 2 and the heat-adhesive yarn 3p, a 3-denier nylon woolly yarn was used as the ground thread insertion yarn 4, and a spandex nylon covering yarn (210 denier) was used as the elastic yarn 5. Deploy. Then, the first yarn 2 is supplied to the first reed, and as shown in FIG.
By supplying heat-adhesive yarn 3p to the reed and continuously knitting chain stitches along one wale as shown in Figure 2b, chain stitches are doubled in all courses and all wales. Formed. In addition, the base thread insertion thread 4 is inserted into the third reed.
is supplied, and the wale is made to underlap to the adjacent wale every fourth course to form a net shape with holes. However, in addition to this, the ground yarn insertion yarn 4 was appropriately transferred to the adjacent wale by means of a francine. Further, the elastic yarn 5 was supplied to the final reed in the handle reed and inserted along each wale. In addition, the runner length of the first yarn 2 of the first reed (knitting yarn length required for knitting 480 courses) is 105.5.
cm, and the runner length of the heat-adhesive yarn 3p of the second reed was set to 103.5 cm, and the stitches formed by the first yarn 2 were formed to be slightly larger than the stitches of the heat-adhesive yarn 3p. Furthermore, the driving was set to 40 courses/inch (15.7 courses/cm) on the machine and 90 courses/inch (35.4 courses/cm) in the finish. After knitting, the above lace fabric is subjected to dry heat treatment at 190°C for 20 seconds to fuse the contact areas between the heat-adhesive yarns 3p,
Furthermore, finishing processing was performed according to a conventional method to obtain a warp knitted lace of an example.

The warp-knitted lace of this example has a soft texture with a small amount of a low-melting synthetic resin layer as an adhesive, and the heat-adhesive threads are fused together, so it cannot be cut with scissors. No fraying occurred from the cut end. When sewing, each chain stitch is composed of two threads, the first thread 2 and the second thread 3, so one of the first thread 2 and the second thread 3 is sewn using the sewing machine needle. Even if one was disconnected, the other remained and no run occurred.

(Effect of the invention) The lace obtained by this invention has two threads forming the chain stitch of each wale over the entire course, so the two threads are used during sewing. Even if one is cut, the other remains to prevent runs and maintain an uninterrupted appearance as a chain stitch.Also, if both are cut, the fused part will prevent runs; Even if an external force strong enough to cause the fused portion to separate is applied, one yarn knits only one wale, while the other yarn reciprocates between multiple wales and knits one yarn in multiple courses. Because it forms a double chain stitch, the run stops at the part where the other yarn moves through the wale, and as a result, no run occurs at all, and even when an elastic yarn is inserted, a run will not occur. can be almost completely prevented.
