Abstract

The invention provides a novel non-woven fabric with high bacteriostatic performance. The novel non-woven fabric is prepared from the following raw materials by weight: 100 to 120 parts of antibacterial polypropylene, 40 to 60 parts of nylon 6, 20 to 40 parts of titanium dioxide-cobaltous phosphate, 10 to 20 parts of a coupling agent and 30 to 50 parts of auxiliary agents consisting of antimony oxide, red phosphorus, aluminum oxide, an anti-oxidant, an ultraviolet absorbent and a plasticizer. The novel non-woven fabric prepared in the invention has more stable antibacterial properties, is non-volatile, long in service life and easy to process and store, does not penetrate into the epidermis of human beings or animals, shows excellent antibacterial effect on specific bacterial strains and has special effects on molds; and through synergism with an inorganic antibacterial agent, the novel non-woven fabric has good safety, heat resistance, sustained-release performance, a broad antibacterial spectrum and small possibility of generating drug resistance.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a novel non-woven fabric with high antibacterial properties. Background technique [0002] Non-woven fabric, also known as non-woven fabric, has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, low price, and recyclable. It is widely used in agriculture, wallpaper, handbags, medical and health, architectural decoration, Clothing, automotive interior decoration and other fields. Modern people have higher and higher requirements for the quality of life, and higher and higher requirements for the antibacterial and antibacterial effects of antibacterial non-woven fabrics. [0003] The main component currently used to prepare antibacterial non-woven fabrics is ordinary polyester fiber or polypropylene fiber. The production process is generally to soak the ordinary fiber in the immersion tank containing the drug,...
