Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides an excellent deodorant property in a field where it is required to remove a malodor containing a plurality of components such as ammonia, hydrogen sulfide, acetic acid and the like, and provides a color fastness and durability. The present invention relates to an excellent deodorant fiber structure.

[0002]

2. Description of the Related Art With the diversification of living environments aiming at comfortable living, human interest in odors has been greatly increased. Under these circumstances, in order to remove malodor with a fibrous structure, a fiber material mainly comprising a thermoplastic polymer compound having a fiber forming ability and a deodorant is melt-spun (Japanese Patent Laid-Open No. 2-157040). (Japanese Patent Application Publication No. JP-A-Heisei 2-216875), a method in which a deodorant is applied via a polyurethane resin composition in post-processing (Japanese Patent Application Laid-Open No. 2-269875), or a method using a polyester resin (Japanese Patent Application Laid-Open No. Hei 7-216751)
Issue public relations).

[0003] However, in the former method of melt-spinning a fiber raw material mainly composed of a thermoplastic polymer compound having a fiber-forming ability and a deodorant, although the durability is obtained, the deodorant is used in the spinning step. There was no versatility in selecting a deodorant because of the problems of thermal stability and particle size.

[0004] On the other hand, in the latter deodorizing process, although the deodorant has versatility, the adhesiveness between a polyurethane resin or a polyester resin and a material fiber is weak.
In addition to the problem of durability, when the amount of binder is increased to increase the durability, the texture becomes hard.

[0005] When a urethane resin is used, the dyeing fastness such as transfer dyeing becomes poor. -It was very difficult to apply it to the field of clothing, etc., which requires high washing and dry cleaning properties, such as clothing.

[0006]

DISCLOSURE OF THE INVENTION The present invention solves the above problems and has excellent deodorizing properties, texture and good dyeing fastness, and also has excellent durability against washing and dry cleaning. It is intended to provide a polyester fiber structure.
