Abstract

The invention provides an antistatic antibacterial acrylic fiber and a preparation method thereof. The anti-static antibacterial acrylic fiber is mainly technically characterized in that a pore-foaming agent and a synergist are put into a spinning solution mainly composed of polyacrylonitrile, a solvent, an antistatic agent and an antibacterial agent. Due to adoption of the pore-foaming agent, thehygroscopicity of the fiber is improved, and the antistatic property of the fiber is facilitated; due to adoption of the synergist, the problem that the antistatic agent and the antibacterial agent are poor in compatibility with polyacrylonitrile stoste is solved, the antistatic properties and the antibacterial properties of the fiber are relatively greatly improved when being compared with thoseof single antistatic agents and antibacterial agents, and the physical mechanical properties of the fiber are not seriously affected. The preparation method comprises the following steps: mixing a base material, namely dried polyacrylonitrile powder, with an antistatic agent, an antibacterial agent, a pore-foaming agent, a synergist and a solvent, heating at certain dissolution temperature so asto obtain a spinning solution, further performing melt-blow spinning on the spinning solution in the air so as to obtain an acrylic fiber, and performing water washing and drying on the obtained fiber, thereby obtaining the acrylic fiber with dual functions of electrostatic resistance and bacterium resistance.

Description

technical field [0001] The invention relates to a dry-process acrylic fiber with dual functions of antistatic and antibacterial and a preparation method thereof. Background technique [0002] Due to its unique dog-bone structure, dry-process acrylic fiber has characteristics close to natural wool. The fabric made of it has good elasticity and light weight. The finished product has the advantages of warmth, comfort, luster and elegance, but dry-process acrylic fiber also has many disadvantages. Due to its hydrophobicity and insulating properties, it has poor hygroscopicity and is prone to static electricity; it has poor antibacterial performance and is prone to breed bacteria. In order to improve its shortcomings, relevant professionals at home and abroad have conducted a lot of research on the antistatic and antibacterial properties of acrylic fibers. Ren Liang introduced a variety of methods to improve the antistatic properties of acrylic fibers in "Methods for Improving th...
