る。2. Description of the Related Art Different shrinkage mixed yarns are used as a technique for expressing a swelling feeling when a woven knit is formed. Above all, it is common to use a polyester yarn obtained by copolymerizing isophthalic acid as the high shrink yarn, or use a spontaneously elongated yarn as the low shrink yarn. However, if the high-shrink yarn obtained by copolymerizing isophthalic acid is used as it is, the texture becomes stiff when a woven knit is formed. In addition, spontaneously stretched yarn is produced by drawing a semi-drawn yarn once at room temperature or by applying a relaxation heat treatment to the semi-drawn yarn as it is. However, there is a problem that the strength is reduced due to the alkali weight loss.

It is known that a complicated process is added during the production of spontaneously-extended yarn to make it thick and thin, to obtain random shrinkage characteristics, and to obtain a swelling feeling close to that of a natural material. However, these are generally complicated and unstable in the production process, and it is difficult to maintain stable quality.

In particular, it consists essentially of polyethylene terephthalate, which is polymerized so that the total mole number of ethylene glycol and terephthalic acid is 95 mole% or more based on the total mole number of the monomers constituting the polyester polymer. It is preferred to use polyester.

However, ethylene glycol and terephthalic acid are used in order to increase the difference in shrinkage. It is also preferable to use a polyester that is copolymerized with other dicarboxylic acid components and / or diol components. For example, isophthalic acid is used as another dicarboxylic acid component, and 2-2-bis [4

呈するため好ましい。Further, in order to obtain a natural heather appearance, it is preferable to employ yarns having different dyeing properties for at least one of the semi-drawn yarn and the fully drawn yarn.
A so-called cationic dye dyeable polyester or a normal pressure cationic dye dyeable polyester obtained by copolymerizing a metal sulfoisophthalic acid or the like is also preferable. In addition, conventional polyethylene terephthalate is conventionally said to have no color depth due to the refractive index of the material itself, but at least one of the semi-drawn yarn and the fully drawn yarn constituting the present invention has a woven or knitted fabric. It is also possible to use a polymer that forms microvoids on the fiber surface due to alkali loss after
It is preferable because it has the effect of reducing the regular reflection of light on the fiber surface and exhibits high color developing properties.

しい。The semi-drawn yarn is usually referred to as a highly oriented undrawn yarn, and has a birefringence (Δn) of 30 × 10 −3 or more and less than 70 × 10 −3 as measured by a polarization analyzer. It is preferable that the yarn has a breaking elongation of 90 to 200%,
The completely drawn yarn is preferably a yarn having the same birefringence (Δn) of 80 × 10 −3 or more and a breaking elongation of 20 to 50%.

い。It is important that there is a difference in the elongation at break between the semi-drawn yarn and the fully drawn yarn described above. This is because the half-drawn yarn is wound around the outside of the fully drawn yarn during false twisting and drawn, and a yarn length difference occurs when untwisted.Then, when heat treatment is performed, this yarn length difference is subjected to relaxation heat treatment. This is because the semi-drawn yarn becomes a spontaneously elongated yarn by producing the same effect as the spun yarn. Therefore, the difference in elongation at break is preferably such that the semi-drawn yarn is 40% or more larger than the fully drawn yarn, more preferably 50% or more, and further preferably 70%.
On the other hand, if it exceeds 180%, on the other hand, there is a large difference in yarn length after the false twist twister, which may cause a problem such as squeak kinep, which is not desirable because a problem in yarn quality occurs.

しい。When performing the above-mentioned false twisting, it is important to keep the heater temperature in the twisting zone at 120 ° C. or less. If the temperature exceeds 120 ° C., the yarn length difference between the semi-drawn yarn and the fully drawn yarn is too large to cause a nep or the crystallization of the half-drawn yarn proceeds, and it is not possible to express a sufficient swelling when woven and knitted. Or Although it varies slightly depending on the degree of orientation of the semi-drawn yarn, it is preferably 100 ° C. or lower, more preferably 80 ° C.
C. or lower, more preferably 70.degree. C. or lower. The lower limit is preferably room temperature or higher (for example, 20 ° C. or higher).

することとなる。After the false twisting, it is important to perform a heat treatment at 70 ° C. or higher. As described above, the semi-drawn yarn substantially drawn by this heat treatment has been subjected to relaxation heat treatment by the difference in yarn length, and has spontaneous elongation characteristics.

ましくは５％以下である。The heater used at this time is preferably a conventional saddle-shaped hot plate or tube heater. It is also preferable to slightly relax the semi-drawn yarn during the heat treatment in order to enhance the spontaneous elongation characteristics of the semi-drawn yarn, reduce the Young's modulus of the fully drawn yarn, and improve the texture of the obtained woven or knitted fabric.
However, this is a range in which the yarn can stably pass over the heater, and the feed rate is preferably 10% or less, more preferably 5% or less.

膨らみ感が強調されてよい。It is also preferable to carry out air entanglement before or after the false twisting. As a result, not only the process passability is improved, but also heat treatment unevenness occurs between the single yarns at the time of heat treatment, and the feeling of random swelling when forming the fabric may be emphasized.

It is also preferable that a real twist is applied.

By doing so, the shrinkage characteristics of fully drawn yarns and the spontaneous elongation characteristics of semi-drawn yarns vary minutely between single yarns, making it possible to construct a fabric and achieve a unique swelling feeling after heat treatment in the dyeing process.

%, And a relaxation heat treatment was performed using a tube heater at 150 ° C. and 500 m / min to obtain a spontaneously elongated yarn. The contraction rate of the spontaneously elongated yarn was -5.8%. However, the yarn at the time of the relaxation heat treatment ran at low tension and was very unstable. Next, the fully drawn yarn obtained in Example 1 was drawn and aligned, subjected to an air entanglement treatment at a feed rate of 2% and a pneumatic pressure of 2 kg / cm 2 to obtain a hetero-shrinkage composite yarn, and woven under the same conditions as in Example 1.
Dyeing and post-processing were performed to obtain a woven fabric.

施例１の織物には大きく劣るものであった。Although the woven fabric had a swelling, the surface was flat, the stiffness did not rebound, and the texture was significantly inferior to the woven fabric of Example 1.
