However, since it has a slimy feeling peculiar to its texture and touch as compared with natural fibers such as cotton and silk, it is limited to a specific field in application development, and its range is limited as compared with natural fibers. Specifically, in the case of polyamide fiber, the water absorbency is poor, so that the slimy feeling at the time of sweating is disliked, and the application to underwear, outwear, kimono applications, etc. is extremely small.

For example, various methods have been proposed to remove the slimy feel peculiar to polyamide fibers by partially removing the polyester component from the mixed spun fiber of polyamide and polyester and forming streak-shaped fine pores in the length direction of the fiber surface.

させてもよい。In the present invention, it is important to use an aqueous emulsion as an oil agent for the obtained fiber. Even if a non-aqueous (straight) oil agent is adhered, the fiber surface is smooth and no change is observed. However, the use of an aqueous emulsion oil agent causes the surface to have irregularities. It can be considered that the formation of the unevenness is caused by the spherulites grown by the adhesion of water, because the unevenness is formed on the surface even when pure water is applied instead of the oil agent. Since the adhesion of water is an important point, a non-aqueous (straight) oil agent may be applied after the adhesion of water.

法があるが、その方法はそれ自体制限を受けない。The amount of the water-based emulsion oil agent adhered can be freely changed within the range in which the yarn can be formed.
The range of 12% is preferable. The higher the EPU, the more easily irregularities are formed, but if the amount applied is too large, the wound fiber may stick, which is not desirable. To apply the oil agent, there is a method of applying the spun fiber before winding the fiber with an oiling roller, measuring oiling or the like, but the method is not limited per se.

徴とする粗面化ポリアミノ繊維の製造方法。1. A formula (1) 200 ≧ [C · COOH] - [C · NH 2]> - 200 .. (1) [ where Shikichu, [C · COOH] and [C · NH 2] is Represents the gram equivalent (geq) amount of terminal carboxyl groups and terminal amino groups per 10 6 g of polyamide, respectively. To a polyamide satisfying the following general formula (2): [In the formula, R represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or an alkoxy group having 1 to 8 carbon atoms. ] A hindered amine compound having three or more substituents represented by the formula 0.3 to 5 per 100 parts by weight of polyamide is added.
A method for producing a roughened polyamino fiber, characterized in that the composition containing parts by weight is melt-spun, and the discharged yarn is provided with an aqueous emulsion to form irregularities due to protrusions of the polyamide itself on the fiber surface. .
