Polyesters such as butylene terephthalate and copolymers or mixtures mainly of these are preferably used.

It is melt-processable at the following temperatures and is water-soluble or water-dispersible. As such a thermoplastic water-absorbing polymer, there is a cross-linked product of polyethylene oxide having a molecular weight of about 100,000 or less, which is commercially available from Sumitomo Seika under the trade name "Aqua Coke".

果が不十分となる。The proportions of polymer A and polymer B in the composition to be subjected to melt spinning are 90 to 99 parts by weight of polymer A and polymer B.
It is necessary to make it 10 to 1 part by weight. Since the polymer B does not have a good fiber-forming property, the polymer B
If the ratio is too large, the spinnability is poor and smooth spinning is difficult. On the other hand, if the proportion of the polymer B is too small, even if the elution treatment is performed, fine pore lines are not sufficiently formed on the fiber surface, and the modifying effect becomes insufficient.
【0010】また、紡出する繊維の断面形状は特に限定

面等の異形断面でもよい。The cross-sectional shape of the fiber to be spun is not particularly limited, and may be a circular cross section, or a modified cross section such as a triangular cross section or a star cross section.

For example, this composition can be used as a sheath component and a core-sheath type composite fiber having the polymer A as a core component. The polymer used for spinning may contain additives such as colorants and antioxidants, if necessary.

である。非水油剤としては、鉱物油を主体とし、平滑

れる。Although melt spinning can be carried out by a conventional method, it is necessary to use a non-aqueous oil agent as a spinning oil agent because the water-absorbing polymer is present on the fiber surface portion in the spun yarn. As the non-aqueous oil agent, an oil agent containing a mineral oil as a main component and containing a leveling agent, an antistatic agent, a sizing agent, etc. is preferably used.

ように選定することが必要である。The yarn to which the non-aqueous oil agent is applied must be wound at a high speed to obtain a highly oriented yarn, or drawn to be wound as a highly oriented yarn. In a method in which a low orientation undrawn yarn is wound and then drawn, it absorbs moisture before it is supplied to the drawing step, making it difficult to draw, and a good fiber cannot be obtained. It is necessary to select the winding speed in the case of winding at a high speed, the drawing speed in the case of winding after stretching and the draw ratio so that the obtained fiber has a strength of about 3 to 5 g / d suitable for clothing.
