Problems solved by technology

Although copper ions and silver ions themselves have a certain antibacterial ability, directly adding metal ions to textile materials will reduce the toughness and elasticity of textile materials, and the safety of human skin in direct contact with fabrics containing metal ions for a long time cannot be fully guaranteed.

Abstract

The invention provides an antibacterial textile material which is prepared from cotton fiber, regenerated cellulose fiber, vinylon, bamboo charcoal fibre and antibacterial composite polyester fiber, wherein the antibacterial composite polyester fiber is prepared from polyester fiber, chitosan fiber, polyacrylic ester and antibacterial microspheres, and the antibacterial microspheres refer to one or mixture of at least two of silver / shell powder / chitosan microspheres, copper / shell powder / chitosan microspheres, titanium dioxide / shell powder / chitosan microspheres. The antibacterial textile material has good toughness, good elasticity and excellent antibacterial performance.

Description

technical field [0001] The invention belongs to the field of synthetic fiber production, and in particular relates to an antibacterial textile material and a preparation method thereof. Background technique [0002] Traditional textile materials mainly refer to fibers, which are the basic unit of textile materials. Fibers are divided into two categories: natural fibers and chemical fibers. Natural fibers are divided into plant fibers, animal fibers and mineral fibers according to their source properties. According to different raw materials, processing methods and components, it can be divided into three categories: regenerated fibers, synthetic fibers and inorganic fibers. At present, chemical fibers dominate the market due to their excellent performance such as various forms and low preparation costs, but they have problems such as low safety, unfriendly to the environment, and difficult degradation. Natural fibers exist in nature and can be obtained directly. Natural f...
