法に関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention is directed to the manufacture of underwear,
The present invention relates to a polyester fiber that has an animal hair tone and is easily dyed with disperse dyes at normal pressure and is suitable for use in sweaters, etc., and a method for producing the same.

ある。However, when dyeing nylon, it is dyed in the same color as wool, making it difficult to dye it in a different color, and it is expensive. On the other hand, polyester fibers can be dyed in a different color from wool or acrylic fibers using disperse dyes. Furthermore, polyester fibers suitable for blending with wool or acrylic fibers can now be manufactured at low cost. Therefore, there is a tendency for fibers used in blends with wool or acrylic fibers to switch from nylon to polyester fibers.

Dyeing must be done under high temperature and pressure, which damages the wool and acrylic fibers that are dyed in the same bath, impairing the texture and appearance of the finished product. Therefore, the use of atmospheric pressure cation dyeable polyester fibers may be considered, but in this case, when blended with acrylic fibers, the 'leaving white' technique is used in dyeing, i.e., the acrylic fibers are dyed but the polyester fibers are not dyed. However, it is not possible to use dyeing techniques that leave the fabric as it is in the Japanese style, and it is not possible to dye it with an excellent appearance.
そのため、羊毛またはアクリル繊維との混紡に適した形

It consists of polyalkylene terephthalate in which 20 mol% is substituted with isophthalic acid groups, the single yarn fineness is 10 to 25 deniers, the number of crimps is 0.5 to 3/inch, and the coefficient of static friction of fiber/fiber on the fiber surface is 0.09 to 0.20, and is achieved by using polyester fibers whose cross-sectional shape is flat with a flatness ratio of 3 to 10.

性等の点から、イソフタル酸基に匹敵するものはない。The fiber of the present invention preferably consists of polyalkylene terephthalate in which 10 to 20 mol% of the terephthalic acid groups are substituted with isophthalic acid groups. Such polyalkylene terephthalate-1 has 10 to 20 terephthalic acid groups.
Examples include polyallene terephthalate or polybutylene terephthalate in which mol% is substituted with isophthalic acid groups, and the former is particularly preferred. Various types of dicarboxylic acid groups can be considered to replace the terephthalic acid group, depending on the availability of the 7-mer, the economical efficiency of the 7-mer, the spinnability of the 7-mer, and the spinnability of the 7-mer, especially as specified in the present invention. spinnability to obtain fibers with specific single yarn fineness, number of crimps, and friction coefficient, heat resistance when made into fibers, dyeability when made into fibers,
In particular, there is nothing comparable to isophthalic acid groups in terms of ease of normal pressure dyeing (1) when dyeing with disperse dyes, commercial productivity, etc.

This makes it difficult to dye wool and acrylic fibers under conditions that do not damage them, making it impossible to achieve the object of the present invention. on the other hand,
If the ratio is too large, problems such as poor threadability during spinning and failure to obtain homogeneous thread quality will occur.

好ましい。Polyalkylene terephthalates suitable for the fibers of the present invention are produced by a conventional method of polycondensing a fullylene glycol such as ethylene glycol or butylene glycol, terephthalic acid, and isophthalic acid. The proportion of terephthalic acid used is 80 to 90 mol% of the acid component, with the remainder being isophthalic acid. In polycondensation, part of the alkylene glycol may be replaced with diethylene glycol. In that case, it is desirable that the proportion of diethylene glycol used (proportion in the glycol component) is within a range in which the total amount including the mol% of isophthalic acid is 20 mol%. The polyalkylene terephthalate used in the present invention preferably has a degree of polymerization corresponding to a viscosity of 0.5 to 0.9 when measured in 0-chlorophenol at 25°C.
本発明のポリエステル繊維においては、単糸繊度、捲縮
数、静摩擦係数か特定の範囲にあり、特定の形状を有す

て得られた製品の触感が硬く不適当である。That is, the polyester fiber of the present invention needs to have a single yarn fineness of 10 to 25 deniers. If the fineness of the single filament is too small, it is difficult to obtain the texture and appearance of animal hair, such as difficulty in producing bristly properties or lack of stiffness. On the other hand, if it is too large, the product obtained by blending or blending with wool or acrylic fiber will have a hard feel and will be inappropriate.

となる。The number of crimp should be in the range of 0.5 to 3 per inch. If the number is less than 0.5, the entanglement will be poor,
The spinnability is poor, and if there are more than three, it will be difficult to create an animal hair-like texture like mohair in the appearance of the final product.

より好ましくない。The fiber/fiber static friction coefficient on the fiber surface is 0.09 to 0.2
Must be 0. If the friction coefficient is larger than 0.20, the smoothness will be poor, and if it is smaller than 0.09, an excessive amount of silicone resin will be required, which is undesirable from the viewpoint of cost.
繊維横断面は、扁平形であることが必要である。The fiber cross section needs to be flat.

味するものである。Typical fiber cross sections are shown in Figures 1-4. In the present invention, as long as the aspect ratio is in the range of 3 to 10, the fibers may have a hollow portion as shown in FIG. It is difficult to obtain a hair-like appearance, and if the aspect ratio is greater than 10, the mechanical strength of the fiber itself will decrease or the fiber will become too soft, which is undesirable.The aspect ratio here is as shown in Figure 4. It means the ratio (L/M) of the maximum long side length L) and the maximum short side length (2).

ができない。Note that the polyester fiber of the present invention is easily dyed under normal pressure. In other words, it is preferable that the dyeing rate is 7096 or more, preferably 90% or more when dyed with a disperse dye of a color index, for example. If the dyeing rate is as low as that of ordinary polyethylene terephthalate homopolymer, the wool dyed in the same bath is easily damaged due to the high temperature dyeing, which has the disadvantage of damaging the surface appearance, so it is dyed under normal pressure. Is it possible to use cationically dyed polyester fibers?If you use normal pressure cationically dyed polyester fibers, if you use them in a blend with acrylic fibers, leave the polyester for one day at the time of dyeing and leave it as a white thread without dyeing it. It is not possible to use post-processing techniques such as acrylic fibers, and the yarn is dyed in the same color as the acrylic fibers, making it impossible to obtain a satisfactory appearance.

が望まれる。In addition, the dyeing rate here refers to the amount of dye adsorbed to the saturated amount when dyeing the fiber at a concentration of 1% by weight with disperse dyes such as Color Index, Tes Bars, and Red 88 at a bath ratio of 1:100 at 98°C. Adsorption amount of 10 to 100 phthalic acid groups
Polyalkylene terephthalate in which 20 mol% is substituted with isophthalic acid is spun, drawn, and crimped, and the single yarn fineness is 10.
It can be obtained by producing polyester fibers having a denier of ~25 denier, a crimp count of 0.5 to 3 crimps/inch, and a flat cross-sectional shape with a flatness ratio of 3 to 10, but in many cases, the static friction of the resulting fibers The coefficient is large. In that case, after adhering silicone resin to the obtained fibers in an amount of 1.5% by weight or less, preferably 3 to 1.2% by weight based on the fibers,
It is desired that the fiber/fiber static friction coefficient be in the range of 0.09 to 0.20 by heat treatment at a temperature of ~180°C.

てはクリンパ−による機械捲縮による方法が好ましい。The above polyalkylene terephthalate is spun, drawn, and crimped by conventional methods. In the present invention, spinning is carried out by a conventional melt spinning method, except that a specially shaped spinneret giving a flat cross section is used. Typical bases used include those shown in FIGS. 5 to 8. Stretching is carried out at a stretching ratio of 1.5 to 6. The crimp can be applied by various methods, but in the present invention, mechanical crimp using a crimper is preferred.

ンには帯電防止剤等の添加剤が含まれていてもよい。The amount applied is 1.5% by weight or less, preferably 0.5% by weight based on the fiber.
It is desirable to add 3 to 1.2% by weight. After applying the silicone resin, it is preferable to perform heat treatment in the range of 140 to 180°C. If the heat treatment temperature is low, the crosslinking reaction between the silicone resin and the polyester fiber will not proceed much, making it difficult to form a cured film on the fiber surface. On the other hand, if the heat treatment temperature is too high, problems such as discoloration of the silicone resin or base oil may occur, which is not preferable.
