Abstract

The invention belongs to the technical field of chemical fiber processing, and particularly relates to a preparation method of antibacterial polyester fiber. The preparation method comprises the following steps: (1), performing coating treatment to silver powder, wherein the used silver powder has the particle size of 1-15 microns; (2), performing drying treatment: drying polyester chips by a vacuum drying oven so as to enable the water content of the polyester chips to be 110ppm, wherein the drying temperature is set to be 100 DEG C; (3), preparing antibacterial functional particles to obtainpolyester particles doped with the silver powder; (4), spinning; (5), performing posttreatment: drafting, winding and doffing prepared filaments. Through coating treatment to the used silver powder,agglomeration of the silver powder is reduced, so that the antibacterial effect of the produced polyester fiber is better and the silver powder in the polyester fiber is unlikely to shed off.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of chemical fiber processing, and in particular relates to a method for preparing antibacterial polyester fibers, which utilizes the bactericidal properties of silver ions to prepare polyester fibers with antibacterial functions. [0003] Background technique: [0004] Polyester fiber has the advantages of high strength, high modulus, high elasticity, good shape retention and heat resistance, and has become the most widely used and most consumed fiber variety. Due to its good wearing performance, polyester fiber is widely used in the field of clothing. With the development of society and the improvement of people's living standards, traditional textile and clothing can no longer meet people's requirements for daily wear. Therefore, functional textile garments have emerged as the times require in recent years. Wearing textiles with antibacterial function can make people's travel and activities safer,...
