These raw threads are used as leg threads or welt threads, knitted on a seamless circular knitting machine or raschel knitting machine, etc., then sewn into a stocking shape, dyed and finished, model set, etc., and then manufactured. be done. In recent years, the stocking knitting process has become faster with the aim of increasing production efficiency. For all seamless circular knitting machines, the rotational speed of the knitting machine used to be around 500 rpm, but now high-speed knitting machines with a rotation speed of 800 to 900 rpm are becoming common, and the rotation speed of the knitting machine is about 500 rpm. However, there remains a need to develop a raw yarn that can be knitted stably on high-speed knitting machines and has the elasticity, abrasion resistance, and transparency required for women's stockings.

ストッキングにならない欠点がある。On the other hand, polyamide-based elastic crimped or torque yarns have high-speed knitting properties, but they have the disadvantage of insufficient stretch recovery due to crimping or strong twist torque, and lack of elasticity. Yes. In addition, polyurethane-based covering threads reflect the stretchability of the polyurethane elastic material, resulting in women's stockings with excellent elasticity. Since the fibers are rolled up, the fineness of the yarn is large, which makes it difficult to make excellent women's stockings.

（耐摩耗性が低い）欠点が有る。On the other hand, many fibers have been proposed in which two components having different shrinkage properties are joined eccentrically within the cross section of the fiber. Among them, it has been proposed that self-crimping composite fibers made of polyurethane elastic material and polycapramide can be used to make women's stockings with particularly excellent elasticity and blindness.
Publication No. 10288,! Temple Publication No. 55-86725,
(Special Publication No. 55-23926). However, these yarns have the disadvantage that the adhesion between the polyurethane elastic body and the polycapramide is insufficient, and the two components peel off when the stockings are worn (low abrasion resistance).

ない欠点がある。As an improvement, a polycarbonate-based polyurethane elastic body with good adhesion to polyamide was used to make composite yarns (Japanese Patent Publication No. 55-22569, Japanese Patent Publication No. 55-22570, Japanese Patent Publication No. 57-84869, Japanese Patent Publication No. 57-84869, Japanese Patent Publication No. 57-84869, Japanese Patent Publication No. 57-84869) '1

Publication No. 5) has been proposed. However, when these raw yarns undergo dyeing processing or heat treatment such as mold setting after stocking knitting, not only does the knitted fabric shrink due to crimping, but the yarn also shrinks significantly in the fiber axis direction, resulting in sufficient product dimensions. There are disadvantages that cannot be avoided.

均一な製品を安定して得られない。In consideration of this drawback, Japanese Patent Publication No. 56-47281 proposes low-temperature finishing conditions. When this yarn is used as stocking leg yarn and knitted on a seamless nine-knitting machine, it can be knitted without any major trouble under the conditions of knitting machine rotation speed of 200 to 400 rl)m, with no knitting irregularities or skipped stitches. Although the product will not be uniform, the knitting machine rotation speed is 800 to 900.
Under high rpm conditions, thread breakage or skipped stitches occur, making stable knitting impossible. In addition, stockings manufactured through processes such as sewing, dyeing and finishing, 9M sets, etc. may have twitching or knitting spots. There are many drawbacks such as
Unable to consistently obtain a uniform product.

Although it is not clear why the product is not stable and uniform in comparison, it is thought to be due to the lower 1 Amariyama.

なる。1) A conventional composite fabric made of polyurethane elastic material and polycapramide is described in Japanese Patent Publication No. 10288/1988, as described in 1. - Self-i@ just by stretching after spinning and spinning alone
As Rx is expressed, the shrinkage force of the polyurethane elastic body in the chamber is extremely large, and stress is always acting on the polyurethane elastic body to cause it to contract even under normal room temperature conditions. Therefore, even after it is rolled up into a cot or cheese shape, shrinkage stress acts gradually over time, and as a result, the raw yarn in the inner layer of the cheese or cot is crimped, resulting in poor unwinding properties when it is rolled up. This causes thread breakage or skipped stitches during high-speed knitting.

に倦縮が発現する。2) When such a fiber is relaxed immediately after stretching, it immediately develops a spiral crimp, but the raw yarn wound into a cot or cheese shape, even when relaxed, as described in Japanese Patent Publication No. 10288/1988, Crimp does not develop immediately; crimping develops after 1 to 2 minutes.
従って、婦人用ストッキングへの編立て工程において捲

れる。Therefore, in the process of knitting women's stockings, the yarn is knitted as a flat yarn with no crimp at all.

が悪くなる。As is well known to those skilled in the art, for example, when polyamide flat raw yarn and polyamide crimped yarn are knitted at high speed, the polyamide crimped yarn can be crimped to compensate for slight fluctuations in raw yarn tension during the knitting process. It is superior in high-speed knitting performance than flat yarn because of its elasticity and smoothness due to its short length of contact with guides or knitting needles. Such conventional raw yarn wound into a cot or cheese has self-crimping properties, but in the process of knitting women's stockings, it is in the form of a flat yarn and has poor high-speed knitting properties.

らない。8) The product dimensions of women's stockings are determined by applying a certain tension in the warp direction or the weft direction (1!lia). Therefore, the dimensions of the product are determined by applying a certain tension in the warp direction or the weft direction. , the knitting size must be increased.

く編立てなければならない。The polyamide crimped yarn has a linear shrinkage rate of 5 during water conduction treatment.
Although it has a low shrinkage rate of ~7%, such conventional raw yarn has a water-making linear shrinkage rate of 20% or more, and the dimensions at the time of knitting must be extremely large.

糸は高速条件下では安定して長時間編立て出来ない欠点
が有る。In the case of a seamless knitting machine, the dimensions during knitting are adjusted by changing the width of the vertical movement of the knitting needles, but with such conventional yarns, this vertical movement must be increased to make the stitches larger after knitting. However, the larger the width of the vertical movement of one stitch, the more likely it is that skipped stitches will occur due to random tension fluctuations, and this tendency is especially noticeable at high speeds of 4 seconds, and the previously proposed yarn is not stable under high speed conditions. It has the disadvantage that it cannot be knitted for a long time.

キング性能も良好なことを見出し、本発明に到達した。As a result of intensive research into composite filaments made of polyurethane elastomer and polycapramide in order to improve the above-mentioned drawbacks, the present inventors discovered that the composite filaments have a specific crimp type and do not spool even when unwound from a cot and cheese and loosened. We have discovered that a stocking yarn with little change in shrinkage shape has good high-speed knitting properties and also has good stocking performance for Sakaji products, and has thus arrived at the present invention.

ない。FIG. 1 is a diagram showing the crimped state of a conventional composite yarn made of polyurethane elastic material and polycapramide, and FIG. 2 is a diagram showing the crimped state of the raw yarn of the present invention. Conventional raw yarn is wound into a cot or cheese in the form of a flat yarn with no crimps, and when it is unwound from the cot or cheese, it gradually develops a crimped form as shown in Figure 1. . On the other hand, the raw yarn of the present invention is wound into a coppice or cheese with gentle wavy crimp as shown in FIG. Moreover, even if it is unrolled from a cot or cheese and discharged under normal temperature and humidity conditions, there is almost no change in the crimp form.

糸切れあるいは目飛びが発生する。The number of crimps, which is an essential requirement for the yarn of the present invention, is 5 crimps/cm or more,
The crimping width of 6 times or less of the fiber diameter indicates the above-mentioned gentle wavy crimping, preferably 8 crimps/cm.
The above is 2 to 4 times, and the crimp elongation rate after unrolling is 50% or less, which indicates that there is very little change in the crimp form even after unrolling from the dough or cheese, and it is preferable. is 4
It is 0% or less. Raw yarns with a crimp count of less than 5 crimps/cm, a crimp width greater than 5 times the rectangular fiber diameter, and a crimp elongation rate of more than 50% after release are unraveled during high-speed knitting. The tension fluctuation is large, and not only does the stocking become uneven,
Thread breakage or skipped stitches occur.

Due to the heat process after knitting, the product shrinks significantly, resulting in insufficient dimensions.
On the other hand, if the Fi content is less than 7%, sufficient shrinkage will not occur even if heat treatment is performed after knitting, and the stockings will lack elasticity.

望ましい。Relaxation heat treatment methods include a method in which the tube is heated by running inside a hollow tube heater using air as a heat medium, a method in which the tube is heated by running on a hot plate, and the like. The method using a hollow chimney heater has lower thermal efficiency than the method using a hot plate, and the heat efficiency is lower than that using a hot plate.
It is necessary to set the temperature at a high temperature of 0 to 70'C, and heat treatment spots are likely to occur. Therefore, the method of hot plate heating is most suitable for the raw yarn of the present invention since there is no uneven heat treatment. In the method of relaxation heat treatment using a hot plate, the hot plate length L (m
), the drawn yarn feeding speed V (m7 minutes) to the hot plate, and the surface temperature T ("C) of the hot plate are preferably set within the range of the following formula.

I can't get it. It is desirable to increase the length of the heater in order to lengthen the heat treatment time, but if the heater length exceeds 121, the rubbing force between the yarn and the heater increases, and uneven crimp of the yarn may occur. There is a tendency for this to occur.

ストッキングが得られる。(Effect of the invention) The raw yarn of the present invention can be used at a stocking circular knitting machine with a knitting machine rotation speed of 80.
Even under high-speed knitting conditions of 0 to 900 rpm, stable knitting is possible without yarn breakage or skipped stitches. Furthermore, knitting irregularities or variations in product dimensions due to fluctuations in unwinding tension occurring in the innermost layer of the soup or cheese do not occur. In addition, since the raw yarn of the present invention has already been crimped from the raw yarn stage, the stockings will shrink to a small size immediately after knitting, and as a result, the products will be pulled together in the process after knitting. It is less likely to cause choking. In addition, stockings with excellent elasticity, transparency, and durability can be obtained from the yarn of the present invention.
