It has excellent washing resistance and is used in a wide range of applications. Among these, polyester fibers used in woven and knitted fabrics such as sports clothing and nonwoven fabrics such as padded cotton are particularly required to have excellent stretchability and elastic recovery.

更に染色性に乏しい等の欠点がある。Up until now, as a method for imparting elasticity to woven or knitted fabrics, there has been a method of mixing or knitting rubber or polyurethane fibers with spun yarn coated with spun yarn, but rubber and polyurethane fibers are expensive. There are certain things, too much elasticity,
Furthermore, it has drawbacks such as poor dyeability.

っていない。In addition, synthetic fibers with high heat shrinkability are used as spun yarn,
There are examples of using yarn that has been subjected to a relaxing heat treatment after that, but the shrinkage is insufficient due to convergence resistance due to the twisting of the spun yarn, or the shrinkage ability is significantly reduced due to the untwisting heat treatment of the spun yarn, so it is difficult to obtain sufficient elasticity. However, it has not yet been possible to provide a woven or knitted fabric having the same characteristics.

めには原綿は良好な捲縮発現力、捲縮保持力および最適
な捲縮数を備えていなければならない。As a method of imparting stretchability to a nonwoven fabric, a method using a conjugate fiber having a three-dimensional structure and a coiled crimp has been proposed. That is, this is a method in which two or more types of polymers having different shrinkage properties are used and spun to produce composite fibers having latent crimp properties, and the composite fibers are blended with binder fibers to produce a nonwoven fabric. For example, there are many proposals such as composite spinning of polyesters with different degrees of polymerization, composite spinning of polyester copolymerized with bifunctional or trifunctional compounds, and homopolyester, etc. - For example, polyester copolymerized with isophthalic acid and homopolyester Composite yarns can be mentioned. In order to apply crimp development treatment to these composite fibers with latent crimp ability and use them as bulky yarns or bulky fabrics, the raw cotton must have good crimp development ability, crimp retention ability, and optimal number of crimp. There must be.

る。However, with conventional composite fibers that combine isophthalic acid copolyester and polyethylene terephthalate,
Although it has the ability to develop crimp, it has a high heat shrinkage rate, so the area shrinkage rate due to heat treatment during nonwoven fabric production is large, and the resulting nonwoven fabric is found to have poor elasticity and elastic recovery.

As disclosed in Japanese Patent Application No. 821, No. 4, there is also an example of a composite fiber in which a copolymerized polyester mainly composed of ethylene terephthalate and polyethylene terephthalate are combined by copolymerizing a structural unit having a metal sulfonate group. However, when the nonwoven fabric obtained from such a composite fiber is used as a base fabric for a poultice, for example, the nonwoven fabric has a copolymerized component of 5

発明に到達した。(Means for Solving the Problems) As a result of intensive studies to solve the above problems, the present inventors have developed an ethylene terephthalate based polyester composite fiber in which a specific amount of inexpensive pentaerythritol is copolymerized as a component of polyester composite fiber. When polyester is used, for example, crimp development and crimp retention capabilities equivalent to those of conventionally known polyester composite fibers made of polyester copolymerized with SIP can be achieved at a low modification rate. The inventors have discovered that a composite fiber suitable for use as a base fabric for poultices and the like can be obtained, and have thus arrived at the present invention.

A polyester (B) copolymerized with 2 to 1 mol %, the composite fiber has a latent crimp ability to develop coil crimp of 35 coils/25 mm or more, and is free shrink heat treated at 170°C. It is a polyester composite fiber characterized by a heat shrinkage rate of 10% or less.

It is a fiber with latent crimp ability that develops coiled crimp through relaxation heat treatment.

Further, in the polyester (B) copolymerized with pentaerythritol, the proportion of pentaerythritol in the copolymer is 0.

．． 3 to 0.8 mol%. If it is less than 0.02 mol %, crimp development power is insufficient, and if it exceeds 1 mol %, single filament breakage or yarn breakage is likely to occur during spinning, making spinning and winding difficult.

トが好ましい。The basic skeleton of this polyester (B) is not particularly limited as long as it is copolymerized with a specific amount of bentaerythritol as described above, but for example, a polyester consisting of ethylene terephthalate units or butylene terephthalate units can be used modified with pentaerythritol. In particular, when considering cost, pentaerythritol-modified polyethylene terephthalate is preferred.

ることができる。In addition, pentaerythritol as a copolymerization component is not only cheaper than the above-mentioned SIP, but also in order to increase the number of crimp after heat treatment, for example, 50/25 mm or more.
While SIP requires a modification rate of 3 to 6 mol % (Japanese Patent Application Laid-Open No. 62-782 No. 4), pentaerythritol can exhibit the same effect with a modification rate of 173 or less.

複合繊維が好ましい。Further, in order to obtain a stretchable bulky fabric or nonwoven fabric, it is necessary to have the ability to develop coil-like crimp of at least 35 pieces/25 mm in the raw cotton state. Such crimp occurs by subjecting the composite fiber consisting of the combination of (A) and (B) above to wet heat or dry heat treatment, but it is possible to control the number of loops to some extent by changing the heat treatment temperature. . In the present invention, 160
Preferably, the composite fiber has a number of crimps of 35/25 mm or more at a temperature of 35° C. or higher.

い。The composite fiber of the present invention can be produced by spinning and drawing in a conventionally known method using a conventional composite fiber melt spinning device, but it is possible to effectively impart latent crimp ability to the fiber. In order to
Preferably, it is desirable to set the temperature to 140 to 180°C.
本発明の複合繊維より得られる原綿−は、梳綿工程にお
いて未開繊部分やネップが発生しない方が好ましく、そ
のためには繊維に機械捲縮を付与することが望ましい。It is preferable that the raw cotton obtained from the composite fiber of the present invention has no unopened portions or neps during the carding process, and for this purpose, it is desirable to mechanically crimp the fiber.

してはスタッフィングボックス式、加熱ギヤー式等が採
用できるが、一般にスタッフィングボックス式がよい。Generally, the occurrence of unopened fibers and neps is closely related to the number of crimps and the effect of crimping.In mechanical crimping, the number of crimps is 7/25m.
If it is less than m, unopened portions are likely to occur, and 20 pieces/25 m
If it exceeds m, neps are likely to occur. Therefore, it is preferable to impart 7 to 20 mechanical crimps/25 mm to the latent crimpable conjugate fiber of the present invention. As a method for imparting mechanical crimp, a stuffing box type, a heated gear type, etc. can be adopted, but the stuffing box type is generally preferred.

であり良好な捲縮発現能を存していなかった。Reference Example 5 - Composite fibers consisting of polyethylene terephthalate with [η) of 0.54 and polyethylene terephthalate with [η) of 0.625] copolymerized with 03 mol% of sodium sulfoisophthalic acid were obtained in the same manner as in Example 1. , 160
The number of crimps after heat treatment for ℃XI minutes is 27/25InI11
Therefore, it did not have a good ability to develop crimp.
