Problems solved by technology

[0004] However, there are still many problems in these deodorizing methods, such as: the deodorant fiber obtained by blend spinning will cause the fiber strength to decrease and the hand feel is not good; the photocatalyst will destroy the fiber strength while deodorizing, and the metal in the fiber The complexation of ions with ammonia, hydrogen sulfide, etc. will affect the fiber color, etc.

Abstract

The invention discloses a preparation method of deodorant cellulose fiber, and belongs to the technical field of fiber production. Firstly, cellulose fiber is subjected to pretreatment by alkali liquid; impurities such as grease on the fiber surface are removed; meanwhile, swelling treatment on the fiber is completed; secondly, soft water is injected, AMPS and AA are added; after uniform stirring,SDS is added; the preparation of a copolymerization mixed liquid is completed; the preparation is convenient; the copolymerization mixed liquid is more uniform; the process control is realized; finally, the treated cellulose fiber and the copolymerization mixed liquid take copolymerization reaction under the initiating effect of ceric ammonium nitrate; a deodorant cellulose fiber product is finally obtained. The deodorant product is prepared by a copolymerization grafting method; the damage to the fiber by the method is small; the fiber strength reduction cannot be caused; the hand feeling ofthe fiber cannot be destroyed; the deodorant fiber can be cyclically used for many times; the characteristics of the color, the texture and the like of the fiber cannot be changed; the market requirements are greatly met, so that the life quality of people is improved.

Description

technical field [0001] The invention relates to a method for preparing fibers, in particular to a method for preparing deodorized cellulose fibers, and belongs to the technical field of fiber production. Background technique [0002] With the improvement of the quality of life, in addition to food, clothing and healthy living requirements, people's demand for a hygienic, fresh and environmentally friendly lifestyle is also increasing. In daily life, people will sweat at any time, especially in a high temperature and airtight environment, there will often be some peculiar smell, that is, sweat smell, sweat smell is due to the secretion of sweat, some organic substances in the sweat release ammonia, acetic acid, odor Valeric acid etc. [0003] At present, there is also a lot of research on deodorant fibers, and there are many deodorant fabrics on the market. The deodorization principles of these products are different: 1. Add physical adsorption materials during fiber spinni...
