Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing river lace in which fraying does not occur at cut ends.

(Prior Art) As shown in FIG. 4, river lace is made of bobbin thread 1. The front warp 2 and the back warp 3 are twisted and intertwined to form a large number of twisted strings 4, and at this time, a part of the front warp 2 is made to protrude like a weft thread and is connected to the adjacent twisted string 4 to form a net-like ground. Formed and braided. Note that backwarp 3 is omitted.

A similar net-like ground may be formed by braiding using only the bobbin thread 1 and the front warp 2. When creating a pattern, prepare a thick pattern thread (not shown) and traverse it from side to side between the bobbin thread 1 of the twisted string 4 and the front warp 2 or back warp 3 at the required locations. It was tied and fixed. In addition, if a edging was required, a thick edging thread was run along the edge of the pattern, and fixed by wrapping it around the bobbin thread 1 together with the front warp 2 and pattern thread at the position where it overlapped with the above-mentioned twisted string 4. . In addition, the above-mentioned bobbin thread 1, front warp 2, bobbin thread 3. For pattern threads and edging threads.

Ordinary fiber yarns such as spun yarns and filament yarns made of natural fibers or synthetic fibers were used.

(Problem to be solved by the invention) The conventional river lace has 1 bobbin thread and 2 front warp threads.
．． The back warp 3, the pattern thread, the edging thread, etc. are braided using non-adhesive ordinary fiber threads, and the loop-shaped weft tip 2a of the front warp 2, the pattern thread, the edging thread, etc. are twisted strings. Since it is fixed by simple twisting of the twisted string 4, the cut end of the twisted string 4 tends to untwist and unravel. When the book is gripped by the horizontal edge 2a and pulled in the vertical direction, the twisted string 4 is untwisted and the horizontal edge 2a, pattern threads, hemming threads, etc. can be easily pulled out. For this reason, when the river lace is sewn along the width direction or the inclination direction during the manufacture of clothing, there is a problem in that the seam misalignment occurs along the seam, and sometimes it frays and separates from the seam.

The present invention provides a river lace that does not cause the cut ends or seams to fray.

(Means for solving the problem) A net-like ground structure including warp-direction twisted strings is braided by at least the front warp and the bobbin thread of the front warp and the back warp, and pattern threads and When forming a pattern by twining edging threads etc. with the above-mentioned twisted strings, heat-adhesive threads soluble in a specific liquid are arranged at arbitrary intervals, and the heat-adhesive threads are made to run in a straight line or zigzag pattern. At the same time, the braid is made so that it is entwined with this twisted string at the intersection with the above twisted string.

As the above-mentioned thermally rational yarn, polyester yarn with a low melting point that is soluble in an alkaline solution as a specific liquid, polyamide yarn with a low melting point that is soluble in warm water as a specific liquid, etc. are used, and in particular, nylon 6゜Nylon 66, nylon 12
A terpolymer copolymer with a melting point of 110 to 120°C is preferable. Braiding is performed by simply inserting the thread through a guide bar for the pattern thread. In addition, bobbin yarn, front warp, back warp, pattern yarn,
It goes without saying that for the edging thread, etc., a thread that does not dissolve or is difficult to dissolve in the above-mentioned specific liquid and has a higher melting point than the thermoplastic thread is used. Further, the arrangement intervals of the thermally rational threads may be either equal intervals or irregular intervals, but the preferred interval is 20 or less twisted cords.

After the above-mentioned braiding, heat treatment is performed at a temperature at which the above-mentioned heat-adhesive threads are melted to bond the yarns in the portions where the heat-adhesive threads are entangled, and then the heat-adhesive threads are heated to a specific liquid in which the heat-adhesive threads are dissolved. A part of the thermally rational yarn after melting and solidification is dissolved and removed by dipping.

(Function) When the heat-adhesive thread is melted by heat treatment, the bobbin thread, front warp, back warp, pattern thread, hemming thread, etc. that sandwich the heat-adhesive thread will melt at the part where the heat-adhesive thread is entangled. While they are adhesively fixed to each other, in the areas where the heat-adhesive threads are exposed without being sandwiched by other threads as described above, the heat-adhesive threads simply melt and form film-like, granular, etc. defects. It is deformed into a regular shape and fixed by cooling. In this case, since the heat-adhesive threads are arranged in a straight line or zigzag shape at predetermined intervals, the portions of the multiple twisted strings located on any width direction line are arranged in the above-mentioned arrangement of the heat-adhesive threads. They are bonded at intervals determined by the interval and their linear or zigzag arrangement.

Next, when immersed in a specific liquid, the heat-adhesive yarn in the exposed part that has solidified into an irregular shape dissolves relatively quickly. Because it is covered.

Its dissolution is suppressed. Therefore, by appropriately setting the dipping time, only the heat-adhesive threads in the exposed portions are dissolved and removed, and the heat-adhesive threads in the bonded portions remain undissolved and maintain the bonded state. As mentioned above, these adhesive parts are arranged at predetermined intervals along any straight line in the width direction, so even if the parts other than the adhesive parts are pulled in the direction of the twisted string, the adhesive parts will be placed in the middle of the adjacent adhesive parts. Only a very slight misalignment occurs, and no misalignment occurs over the entire length between adjacent bonded parts.

(Example 1) As shown in FIG. 1, bobbin thread 11. front warp 1
A net-like river lace consisting of 2 and back warp 13 was braided. However, nylon multifilament thread (40 denier) is used for the bobbin thread 11, nylon multifilament thread (40 denier) is used for the front warp 12, and nylon multifilament thread (40 denier) is used for the back warp 13. A thermoadhesive yarn 14 (trade name "Elder", manufactured by Toshi Co., Ltd., 30 denier) made of a copolymer of nylon 6, nylon 66, and nylon 12 was attached to every other back warp 13.

That is, one heat-adhesive thread 14 was arranged for two twisted strings 15. However, the illustration of the back warp 13 at the position where the heat-adhesive thread 14 is arranged is omitted.

After braiding and scouring the above river lace, dry heat treatment is performed at 185° C. for 50 seconds using a heat setting machine to melt the heat-adhesive yarn 14, and then 9
Dyeing and heat-adhesive yarn 1 by immersing it in a dye solution at 0°C for 60 minutes
A portion of 4 was dissolved at the same time, and then dried and finished according to a conventional method.

The resulting product has almost the same texture and appearance as the conventional product, with the heat-adhesive yarn 14 in the exposed portions not covered by the bobbin thread 11, front warp 12, back warp 13, etc. disappearing. Moreover, since every other twisted string 15 is bonded in a dotted line shape by the heat-adhesive thread 14 of the portion covered by the bobbin thread 11, etc., it can be sewn along the width direction. Even when the lace fabric was pulled perpendicular to the seams, no misalignment occurred along the seams.

In addition, a washing test was carried out 10 times, but no peeling or shifting occurred at all.

(Example 2) As shown in FIG. 2, the bobbin thread 21. front warp 2
A net-like river lace consisting of 2 and heat-adhesive yarn 23 was produced. However, the bobbin thread 21 is a nylon multifilament thread (40 denier), the front warp 22 is a nylon multifilament thread (40 denier), and the heat adhesive yarn 23 is the heat adhesive yarn of Example 1. Using the same material as No. 14, the cords were arranged in every other twisted cord 24 and spliced to the front warp 22 for braiding.

Note that the front warp 22 at the position where the heat-adhesive yarn 23 is arranged is omitted from illustration.

When the above-mentioned river lace 22 was finished by the same treatment as in Example 1, a river lace with good appearance and feel as in Example 1 and which did not fray after being sewn or washed was obtained. However, in this Example 2, since the heat-adhesive yarn 23 was used as a splint with the front warp 22,
A loop-shaped protruding lateral tip portion 23a was formed, and while the portion to be dissolved and removed was increased compared to Example 1, the adhesive portion was dispersed and the texture was slightly soft.

(Example 3) As shown in FIG. 3, a patterned portion 34 was formed on a ground portion 32 made of twisted strings 31 similar to that of Example 2 using pattern threads 33, and bordered with hemming threads 35. However, the pattern thread 33 is a nylon multifilament thread (100 denier), and the edging thread 35 is a nylon multifilament thread (4 denier).
20 denier), and 1 of the above twisted string 31.
The same heat-adhesive thread 36 as in Example 1.2 is arranged for every 0 threads, that is, at equal intervals of about 1011 III, and the heat-adhesive thread 36 is arranged in a width spanning the 17 threads of the twisted string 31. Lead in a zigzag pattern, the folded end and the middle twisted string 3
It was braided so that it was wrapped around the twisted string 31 at least once at the intersection with 1.

After the above braiding, the same treatment as in Example 1.2 was carried out and the appearance and texture were almost the same as the conventional product.
River lace that does not fray when sewn or washed was obtained. In addition, in this Example 3, the arrangement density of the heat-adhesive threads 36 is coarser than in Example 1.2, and the heat-adhesive threads 36 traverse a wide range, so there are many threads in the bonded part. The texture was more flexible. Furthermore, in this Example 3, the heat-adhesive yarn 3
6 may be used by doubling a normal thread. In this case, the heat-adhesive thread 36 is reinforced, and after it is dissolved and removed, the normal thread forms a pattern.

(Effects of the Invention) The present invention is capable of forming heat-adhesive yarns by inserting heat-adhesive threads linearly or zigzagly at arbitrary intervals and entangling them around a twisted string, and by melting the heat-adhesive threads. Conventional products that do not use heat-adhesive threads because they adhere to the parts sandwiched between other threads and then remove the parts that do not contribute to the adhesion by dissolving the heat-adhesive threads. The appearance and texture are almost the same as that of the original, and it does not fray when cut or sewn along the edges of the pattern or along the widthwise lines, and has good adhesion even after repeated washing more than 10 times. No damage at all.
