糸の開発が要望されていた。Conventional silk-like polyester filament yarn has a triangular cross-section similar to that of silk, and this cross-section and the combination of polyester alkali weight loss technology form the basis of the silk-like texture. In addition, as an application of this technology, in order to make polyester filaments that are more silk-like, composite spinning of filament yarns with different shrinkage rates, mixed fibers of filament yarns with different shrinkage rates, partial heat treatment of single shrinkage yarns, and filament yarns with different shrinkage rates can be applied. Although techniques such as partial heat treatment are beginning to make up the majority of silk-like knitted fabrics (including silk), they are still far from natural silk. Furthermore, many thick and thin threads have been developed to achieve the unevenness and appearance of silk threads. However, yarns like Thick and Thin generally have a high shrinkage rate of 30% or more, and -1: Because the hot water shrinkage rates of the yarns in the thick and non-thick areas are greatly different,
After the knitted fabric is finished, the heat during the dyeing process causes a υ"wrinkle" phenomenon, which causes wrinkles on the surface of the knitted fabric, which becomes a problem. In addition, yarns produced using these techniques are silk-like bodied IJ ester filaments that have straightness of bulk, fine unevenness, and uniform dyeability (satisfied with straightness of bulk and unevenness). There was a demand for the development of thread.

次に本発明の第2番目の発明(製造方法)について説明

ラス転位点以下の温度を用いることが不均一な延伸を行
なううえで重要である。ガラス転位点以上の温度の場合
は延伸点の固定化が起こり均一な延伸糸条となる。ND indicates the natural stretching ratio, and NA indicates the stretching ratio. In producing a polyester yarn with yarn unevenness, a small difference in hot water shrinkage rate, and excellent bulk properties as in the present invention, the important points are a method for imparting yarn unevenness and a heat treatment method for reducing hot water shrinkage unevenness. ,
These include bulky heat treatment methods. Pin 8 is important for controlling unevenness. In other words, it is necessary to eliminate vibration and to keep the stretching tension uniform and stabilized. The yarn 5 fed from the feed roller 7 contacts the pin at an acute angle or is wound around the pin several times, thereby making it possible to control unevenness. In other words, the stretching point of the thread 5 is the circumference of the pin.
Control by dispersing into two. If a heat roller or the like is used as the feed roller 7 without using the pin 8, it is impossible to control unevenness at all. It is important to use the temperature of the pins 8 at a temperature below the glass transition point in order to perform non-uniform stretching. When the temperature is higher than the glass transition point, the drawing point is fixed, resulting in a uniform drawn yarn.
熱板9は糸条の熱処理とさらに延伸のランダム化に必要
である。熱水収縮率差を2係以内の糸条とするだめには
熱板9の温度は結晶化開始温度プラス5℃(すなわち9

あるいはカサ高不足などの問題が起こる。延伸倍率はム
ラの付与伸度の適正化に重要なポイントであり、自然延
伸倍率ND以下では未延伸部、延伸部が混在する。The hot plate 9 is necessary for heat treating the yarn and further randomizing the drawing. In order to make yarn with a difference in hot water shrinkage rate within 2 coefficients, the temperature of the hot plate 9 should be 5°C above the crystallization start temperature (i.e. 9°C).
5°C) to 165°C is essential. If the hot plate temperature is lower than this, there will be problems such as excessive shrinkage, and if it is higher than this, problems will occur such as too low shrinkage or insufficient bulk. The stretching ratio is an important point in optimizing the degree of elongation that imparts unevenness, and at a natural stretching ratio of ND or lower, unstretched areas and stretched areas coexist.
しかしこの混在が染ムラに収縮率ムラとして表られれな
い延伸倍率(NA/ND)1.045〜1.241はム
ラ感、カサ高性に最も効果が良く、この範囲以外では両
者を満足することができない。However, a stretch ratio (NA/ND) of 1.045 to 1.241, where this mixture does not appear as uneven dyeing or shrinkage rate unevenness, is most effective in reducing unevenness and bulkiness, and outside this range both can be satisfied. I can't.

分とするコンジュゲ−1・繊維を使用する必要がある。In addition, in the method of the present invention, it is necessary to use fibers having the cross-sectional shape of the constituent fibers as illustrated in FIG. 7, or conjugate 1 fibers having the fibers as an inner layer component.

の条件の組み合わせにより微細なムラを形成させ易いか
らである。This is because when the raw yarn has such a multilobed shape and has a notch at the tip, drawing unevenness peculiar to the hot-drawn yarn is likely to occur, and the yarn can be made to resemble silk. It is still necessary that the raw yarn of the present invention be a highly oriented undrawn yarn. Such highly oriented undrawn yarn can be spun at a spinning speed of 2500 to 5000 m/
It refers to one with a birefringence of about 002 to 007. The reason why such a highly oriented undrawn yarn is employed is that it is easy to appropriately select the stretching ratio, and fine unevenness is easily formed by a combination of other conditions such as the stretching temperature.

As shown in Figure (A), the Worcester unevenness U% is relatively lower than that of silk (Figure 1 (C)), and yet it is large as shown in Figure 1 (C). Thread unevenness (
In contrast to A), yarn unevenness is a mixture of small yarn unevenness (B), whereas the conventional yarn has yarn unevenness (B) due to 7 un-done yarns, and even in the Worcester unevenness U%, there are 2 yarn unevennesses. The invented yarn is far from the form of silk. This is the most important feature for the yarn of the present invention. A C-turn due to uneven hot water shrinkage rate is shown in Figure 2. Hot water shrinkage rate difference 05-2.0%,
Table 1 shows the results of counting the number of pieces of 2.0 or more in the places marked with a circle as shown in Figure 2.

のために。Conventional normal yarns have 2 yarns/rn or less, conventional partial heat treatment yarns have 28 yarns/rn or more, and thick and thin yarns have 6 yarns/rn or more. However, the difference in hot water shrinkage rate is more than 2 cm:
For example, during the finishing process of textiles, a ``wrinkle'' phenomenon occurs, resulting in grains. This difference in hot water shrinkage rate of 20% or more is included in the partial heat treatment system of conventional yarns and knock-and-thin yarns.
This is a problem when finishing textiles. For this.

常の延伸糸の伸度65係あるいはそれ以下が好ましい。The bulk height of the yarn of the present invention is that the difference in shrinkage rate due to heat is small, so a uniform bulk of 6'' yarn can be obtained, similar to that obtained with silk. It is possible to obtain a bulk height higher than that of the invented yarn.However, this bulk height is a walnut-like bulk height that takes advantage of the difference in shrinkage rate due to heat among the yarns, and it is difficult to obtain silk-like knitted fabrics. It is not a desirable bulk height.The bulk density of the yarn needs to be 12 cc/g or more to obtain a silk-like knitted fabric, and it is difficult to obtain a silk-like knitted fabric with a bulk height lower than this. Conventional thick and thin yarns with high elongation and a high hot water shrinkage rate of 4 or more are difficult to handle in high-order processing. preferable.
