Embodiment 1

[0039] The present embodiment provides a preparation method of antibacterial polyphenylene sulfide fiber, which is characterized in that the method adopts polyphenylene sulfide antibacterial masterbatch to prepare antibacterial polyphenylene sulfide fiber, and the polyphenylene sulfide antibacterial masterbatch is calculated by weight. In terms of percentage, it is composed of the following raw materials: 20% of antibacterial powder, 0.2% of antioxidant, 4% of dispersant, and 75.8% of polyphenylene sulfide powder.

[0040] The preparation process of polyphenylene sulfide antibacterial masterbatch is as follows:

[0041] First, the polyphenylene sulfide powder and antibacterial powder were vacuum-dried in a vacuum drying oven, first dried at 120 °C for 2 hours, then raised to 140 °C for 4 hours, and the vacuum degree was always maintained at 0.05~1.0MPa. After drying, polyphenylene The moisture in the sulfide powder should be less than 0.003%;

[0042] Secondly, after mixing t...

Abstract

The invention provides a preparation method of antibacterial polyphenylene sulfide fibers. According to the method, the antibacterial polyphenylene sulfide fibers are prepared from antibacterial polyphenylene sulfide master batch; the antibacterial polyphenylene sulfide master batch is prepared from raw materials including, by weight, 20%-30% of antibacterial powder, 0.2%-0.3% of an antioxidant, 4%-7% of a dispersing agent and 62.7%-75.8% of polyphenylene sulfide powder, and the sum of the weight percentages of the raw materials is 100%; and the antibacterial powder is prepared from raw materials including, by weight, 80% of polymer-coated CePO4 nano-powder and 20% of Ce(OH)4 nano-powder. The antibacterial polyphenylene sulfide master batch prepared with the method is used for spinning, and the spun antibacterial polyphenylene sulfide fibers have the excellent mechanical properties and the excellent antibacterial performance. Antibacterial fabric prepared through blending of the antibacterial polyphenylene sulfide fibers with common polyphenylene sulfide fibers in a certain ratio has the relatively high antibacterial rate, and the production cost of the antibacterial fabric can bereduced substantially.

Description

technical field [0001] The invention belongs to the field of antibacterial modification of fibers, relates to polyphenylene sulfide fibers, and in particular relates to a preparation method of antibacterial polyphenylene sulfide fibers. Background technique [0002] In recent years, polyphenylene sulfide fibers have been widely used in the textile industry due to their good flame retardancy, chemical corrosion 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 beginning of human social activities, the widespread existence and spread of microorganisms such as bacteria has always 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...
