する方法が数多く提案されている。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for producing thick and thin polyester yarn, and more specifically, it is made of filaments with uneven thickness in the longitudinal direction, and is easy to post-process. The present invention relates to a method for producing thick and thin polyester yarn that is extremely easy to handle.゛・ (Prior art) Conventionally, Japanese Patent Publication No. 41-6615 and Japanese Patent Publication No. 43-19
As shown in Japanese Patent No. 627 and the like, many methods have been proposed for producing undrawn IJ ester-based multifilament yarns into unrestricted drawing (extremely thick and fine yarns).
これらの方法で製造された太細糸は、殆んどジョーゼッ
トなどの強撚織物分野に向けられている。Thick and fine yarns produced by these methods are mostly used in the field of highly twisted textiles such as georgette.

時に糸の太糸部(未延伸部)の劣fヒ。After the woven fabric is subjected to alkali weight loss processing, it is dyed and finished to become a finished product, but during this alkali weight loss process, the thick yarn portion (undrawn portion) of the yarn becomes inferior.

Since it is not carried out, the hot water shrinkage rate of thick and thin yarn is 520 to 5.
The result is a large difference in yarn quality between the inner and outer layers of the twisting cylinder when the twist is set after one strong twist.

On the other hand, the outer layer yarn shrinks, resulting in a large difference in hot water shrinkage rate and Denny/I difference between the inner layer yarn and the outer layer yarn, such as rounding, uneven width of the fabric, and wrapping steps. disadvantages arise. This necessitated the use of complicated notifications, making production process control extremely difficult and resulting in poor yields.

- Since the texture was also very poor, a highly twisted textured fabric with a luxurious feel could not be obtained. Therefore, in order to eliminate such drawbacks, we have conducted extensive research into molds, and as a result we have arrived at the present invention.

50X10−3と規定しているのは。Next, the physical properties of the supply system are very important, and the present invention is limited to the following. That is, the birefringence △n of the thick yarn part of the polyester multifilament yarn is 15X10"3~
It is specified as 50X10-3.

で本発明の条件にて延伸する必要がないからである。Threads with a diameter of less than 15 x 10-3 and those exceeding 50 It is less than %,
This is because there is no particular problem with the handling notes during twisting and setting, so there is no need to stretch the yarn under the conditions of the present invention.

で本発明から除外されるのである。In addition, when the polyester multifilament yarn serving as the supply system has a UR value of less than 40% and a P value of less than 4 wires/m and is stretched under the conditions of the present invention, the UR value is 20% or less,
When the P value is 3 digits/m or less, the contrast becomes unclear and no characteristics can be expressed, so it is excluded from the present invention.

The maximum value (CH) and minimum value (CH) for the yarn length of 5 m on the obtained chart were measured.
The difference from (H) to the value corresponding to the yarn length of 20 m (4 values) is calculated and averaged to obtain the value.

次に、これらの条件を満足するポリエステル系マルチフ
ィラメント糸の延伸条件の設定方法について説明する。Next, a method of setting stretching conditions for a polyester multifilament yarn that satisfies these conditions will be described.

握供出来るのである。Strong twisting, no need to separate the inner and outer layers of the twisted yarn cylinder during setting, leaving untwisted torque, and in order to obtain a yarn with good width and texture in the fusing process after weaving, hot water shrinkage of the yarn is necessary. It has been known from past experience that it is sufficient to keep it below tlO%. For this reason, while maintaining the contrast of the shading of the yarn, when heat setting the yarn, the hot water shrinkage rate t-
If the K is set to 10% or less, there is no need to separate the inner and outer layers of the twine cylinder when setting the yarn, and it is possible to easily hold thick and fine yarns with width and texture during weaving and relaxing. .
このような糸を得るための延伸、熱セットするときの延
伸倍率であるが、1.02〜1.06倍、好ましくは1
.03〜1.05倍の延伸倍率で延伸する必要がある。The stretching ratio during stretching and heat setting to obtain such a yarn is 1.02 to 1.06 times, preferably 1.
.. It is necessary to stretch at a stretching ratio of 0.03 to 1.05.

足する延伸倍率に設定してやる必要がある。If the draw ratio is less than 1.02 times, the thread tends to sag, the thread becomes unstable, and the heat set tends to vary. Most of the thick yarn part is stretched, and even if dyed, the contrast will be small, so it is necessary to set a stretching ratio that satisfies this range.

る。Next, regarding heat setting conditions, it is necessary to set the temperature of the heating element that the yarn comes into contact with at 110 to 140°C. If the temperature of the heating element is less than 110°C, the heat setting effect will be small;
The hot water shrinkage rate of the yarn cannot be kept below 10%, and if the temperature exceeds 140°C, the thick yarn portion of the yarn will undergo thermal deterioration, resulting in a significant decrease in the strength of the yarn. .

力などの面で問題が生じ易い。The setting time of the thread, that is, the contact time of the thread with the heating element is 0.5 x 10-3 to 2.5 x 10-3.
It is necessary to set it to 3 (minutes). This is because if the contact time of the thread with the heating element is less than 0.5 x 10-3 C minutes), sufficient heat setting effect cannot be given at the heating element temperature range of 110 to 140°C. It is not possible to reduce the water shrinkage rate to less than 10%, and 2.5X10
Even if the yarn is kept in contact with the heating element for a time exceeding C minutes), the heat setting effect will be saturated, and no further effect can be expected; on the contrary, the equipment will become larger and the yarn processing speed will decrease. It is slow, the operation is complicated, the processing cost is high, and problems tend to occur in terms of the strength of the thread.
