Abstract

The invention relates to an antigen fibrillated cellulose fiber and a preparation method thereof. The preparation method comprises the following steps of extruding, solidifying, drawing and washing acellulose fiber spinning solution through a spinning nozzle to prepare a washed silk, and rinsing and drying after processing the washed silk with a crosslinking agent water solution to prepare the antigen fibrillated cellulose fiber, wherein the washing temperature is larger than 90 DEG C, the temperature of the processed crosslinking agent water solution is 65-90 DEG C, and the rinsing temperature is 20-40 DEG C, and a crosslinking agent comprises more than one of a group capable of forming a covalent bond with cellulose hydroxyl, a group capable of performing a self-crosslinking reaction and a group capable of forming a hydrogen bond with the cellulose hydroxyl. The prepared antigen fibrillated cellulose fiber mainly comprises a cellulose fiber matrix and a crosslinking agent dispersedin the cellulose fiber matrix. The preparation method is simple in process and gentle in condition, and the prepared antigen fibrillated cellulose fiber is excellent in mechanical performance, and excellent in washing resistance.

Description

technical field [0001] The invention belongs to the technical field of fiber production, and relates to an anti-fibrillation cellulose fiber and a preparation method thereof. Background technique [0002] Cotton and hemp fibers in cellulose fibers have been used as important textile raw materials for a long time because their products have good thermal performance. Because of its advantages of being renewable, non-toxic, comfortable fabrics, hygienic and healthy, degradable waste and no white pollution, it has been the most important raw material for textiles for a long time. With the development of society, although Polyester fiber has replaced its role to a certain extent, but it is still the mainstream raw material for textiles. However, with the continuous development of the market, the demand for cellulose fibers is increasing day by day, and the output of natural cellulose fibers such as cotton and hemp is limited, and it is difficult to meet the growing consumer dema...
