Abstract

The invention provides a preparation method of a wormwood micropowder composite acrylic fiber polymer material fiber. The method comprises the steps of preparation of a modified polyacrylonitrile spinning solution and preparation, blending and spinning forming of wormwood micropowder. According to the wormwood micropowder composite acrylic fiber polymer material fiber, the breaking strength is 7.66-8.24 cN/dtex, the elongation at break is 56.8-59.2%, the breaking strength after 800-hour solarization is 7.12-7.95 cN/dtex, the rebound rate when the fiber is elongated by 20% is 82.5-94.0%, and the dry wear-resisting number is 1998-2011. The fiber has different degrees of inhibition effect on aspergillus niger, gold alpha-hemolytic streptococcus, diplococcus pneumoniae, corynebacterium diphtheriae, sonne bacillus, typhoid and paratyphoid bacillus, vibrio cholerae and the like; the moisture regain rate of a fabric prepared from the fiber is 1.98-2.01%, and the anti-pilling level of the fabric is higher than level 4.

Description

technical field [0001] The invention belongs to the technical field of textile materials and relates to a composite polymer material fiber, in particular to a wormwood micropowder composite acrylic fiber polymer material fiber and a preparation method thereof. Background technique [0002] Acrylic fiber, that is, polyacrylonitrile fiber, is known as artificial wool. It has the advantages of softness, easy dyeing and light resistance. The softening temperature of fiber is 190-230℃, it can resist acid, oxidant and general organic solvent, but its alkali resistance is poor. [0003] The invention of patent No. CN200810064708.8 provides a method for processing acrylic fibers, which dips acrylic fibers in a chemical bath for 10-15s at room temperature, then puts them into boiling water and washes them for 10-15s, then dries them, and then rinses them in 100-120 Drying at ℃ for 15-20min completes the modification of the acrylic fiber surface; wherein the chemical bath consists o...
