Abstract

Provided is a mesoporous zirconium-phosphate loaded nano-silver antibacterial polyester fiber and method for preparation thereof. The mesoporous zirconium-phosphate loaded nano-silver antibacterial polyester fiber comprises a polyester matrix; said polyester matrix has dispersed therein a Ag@ mesoporous zirconium phosphate. The method for preparing the mesoporous zirconium-phosphate loaded nano-silver antibacterial polyester fiber comprises: preparing a silver @ mesoporous zirconium phosphate sol precursor; the described silver @ mesoporous zirconium phosphate sol precursor, terephthalic acid (PTA), a diol, a stabilizing agent, and a catalyst are added in proportion to a polyester reactor; performing in situ polymerization and oxidation-reduction reaction to prepare a mesoporous zirconium phosphate-nano-silver antibacterial composite material, and drying and performing melt spinning to make a mesoporous zirconium-phosphate loaded nano-silver antibacterial polyester fiber.

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 polyester 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...
