Problems solved by technology

[0004] According to the principle of capillary water absorption, the present invention provides a new method for preparing polyester fiber filaments with a large number of pores on the surface and inside. The fiber uses a mixed solution of polyester and chitosan as a spinning solution, and is spun by a dry method. Prepared by enzymatically decomposing chitosan, it can further improve the hygroscopicity of the existing special-shaped yarn, and greatly improve the defects of smooth fiber surface and poor hygroscopicity

Abstract

The invention discloses a hygroscopic polyester fiber and a preparation method thereof. The preparation method comprises the following steps: 1) preparing polyester through substitution reaction of terephthaloyl chloride and ethylene glycol, and mixing and dissolving the polyester with chitosan to obtain a spinning solution; 2) performing dry spinning; and 3) hydrolyzing chitosan blended in fiberfilaments by using cellulase and N-acetylglucosaminidase to obtain the fiber filaments with a large number of pore channels in the surfaces and the interiors. The defects of smooth surface and poor hygroscopicity of a PET fiber are overcome.

Description

technical field [0001] The invention belongs to the field of synthetic fibers, and in particular relates to a hygroscopic polyester fiber and a preparation method thereof. Background technique [0002] As the largest synthetic fiber, polyester is polyethylene terephthalate, or PET for short, which is formed by esterification polymerization of ethylene glycol and terephthalic acid. Polyester has many excellent properties, such as excellent stretchability and shrinkage resistance, high elastic modulus and breaking strength, good resilience, good thermoplasticity, heat and light resistance, stable size, and low price, so it is widely used in clothing industry. However, polyester has disadvantages such as poor dyeability, poor hygroscopicity, and smooth surface. Therefore, in order to improve the shortcomings of polyester, it is necessary to modify polyester. [0003] Carrying out hygroscopicity modification to PET can start from many aspects, prior art mainly carries out mod...
