Abstract

The invention provides mesoporous zirconium phosphate-loaded nanosilver antibacterial polyamide fiber and a preparation method of the mesoporous zirconium phosphate-loaded nanosilver antibacterial polyamide fiber. The mesoporous zirconium phosphate-loaded nanosilver antibacterial polyamide fiber is characterized by being prepared from a polyamide substrate, wherein Ag-coated mesoporous zirconium phosphate antibacterial powder is dispersed in the polyamide substrate. The preparation method comprises the steps of preparing the Ag-coated mesoporous zirconium phosphate antibacterial powder; adding raw materials comprising the Ag-coated mesoporous zirconium phosphate antibacterial powder and a polyamide reactive monomer into a polyamide reactor for carrying out in-situ polymerization to prepare a mesoporous zirconium phosphate-nanosilver antibacterial composite material; drying; finally spinning the antibacterial polyamide fiber carrying nanosilver on mesoporous zirconium phosphate through a melt spinning method. The preparation method provided by the invention has the advantages that the operation is simple, effectiveness is realized, the cost is low, the effect is durable, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the field of preparation of antibacterial fibers, in particular to a mesoporous zirconium phosphate-loaded nano-silver antibacterial polyamide fiber 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. 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 durin...
