Abstract

The invention provides a preparation method of antibacterial polyphenylene sulfide fiber. The method uses polyphenylene sulfide antibacterial masterbatch to prepare antibacterial polyphenylene sulfide fiber. The polyphenylene sulfide antibacterial masterbatch is expressed in weight percentage , is composed of the following raw materials: 20%-30% antibacterial powder, 0.2%-0.3% antioxidant, 4%-7% dispersant, 62.7%-75.8% polyphenylene sulfide powder, and 62.7%-75.8% polyphenylene sulfide powder. The sum of the percentages by weight is 100%; the antibacterial powder, in percentage by weight, consists of the following raw materials: polymer-encapsulated CePO 4 Nano powder 80%, Ce(OH) 4 Nano powder is 20%. The antibacterial polyphenylene sulfide masterbatch prepared by the invention is used for spinning, and the spun antibacterial polyphenylene sulfide fiber has excellent mechanical properties and excellent antibacterial performance. The antibacterial fabric prepared by blending with ordinary polyphenylene sulfide fiber in a certain proportion has a high antibacterial rate, which can greatly reduce the production cost of antibacterial fabric.

Description

technical field [0001] The invention belongs to the field of fiber antibacterial modification, and relates to polyphenylene sulfide fibers, in particular to a preparation method of antibacterial polyphenylene sulfide fibers. Background technique [0002] In recent years, polyphenylene sulfide fiber has been widely used in the textile industry due to its good flame retardancy, chemical resistance, high temperature resistance and physical and mechanical properties. However, with the improvement of people's health awareness, the hygienic performance of textiles has also received more and more attention. Since the existence of human social activities, the widespread existence and spread of bacteria and other microorganisms has been an important threat to human health. The porous structure of textiles is more likely to become a breeding ground for bacteria and fungi, which in turn affects people's health. Therefore, the research and development of antibacterial textiles has pra...
