Abstract

The invention provides a nano-silver antibacterial fiber loaded with mesoporous zirconium phosphate and a preparation method thereof. The nano-silver antibacterial fiber loaded with mesoporous zirconium phosphate is characterized in that it includes a polymer matrix, and Ag@mesoporous zirconium phosphate is dispersed in the polymer matrix. The preparation method of the above-mentioned mesoporous zirconium phosphate-loaded nano-silver antibacterial fiber includes: preparing the silver@mesoporous zirconium phosphate sol precursor, and the above-mentioned silver@mesoporous zirconium phosphate sol precursor, terephthalic acid (PTA), two Polyhydric alcohols, stabilizers and catalysts are added in proportion to the polyester reactor for in-situ polymerization, and the polymerized products are granulated to obtain nano-silver antibacterial masterbatches, which are blended and granulated with nano-silver antibacterial masterbatches and polymers, dried, Mesoporous zirconium phosphate-loaded nano-silver antibacterial fibers were obtained by melt spinning. The method of the invention is simple in operation, high in efficiency, low in cost, durable in effect and broad in application prospect.

Description

technical field [0001] The invention belongs to the field of preparation of antibacterial fibers, in particular to a nano-silver antibacterial fiber loaded with mesoporous zirconium phosphate and a preparation method thereof. Background technique [0002] In today's society, the extreme environment, environmental pollution and other ecological environments have seriously deteriorated, and special living microenvironments such as confined spaces have led to an urgent need for functional protective textiles. At present, the fibers used to prepare textiles do not have antibacterial ability, and under certain conditions, they will provide an environment for bacteria to survive and reproduce, threatening human health. The main method to solve the antibacterial problem of fibers is to use antibacterial nanoparticles and polymer matrix for composite modification to prepare modified fibers with antibacterial effects. The fiber will gradually release antibacterial ingredients during...
