Problems solved by technology

[0002] With the gradual development of the level of industrialization, the pollution of the environment is becoming more and more serious, especially the pollution of the air, which is increasingly affecting our health. The seriously polluted air makes the incidence of respiratory diseases increase day by day, while the existing common Non-woven fabrics and protective masks made of activated carbon non-woven fabrics, the functions of deodorization, self-cleaning and air purification are far from meeting people's needs, so there is an urgent need for a non-woven fabric with excellent self-purification and adsorption functions. Cloth to prepare masks with protective functions

Abstract

A non-woven fabric containing a photocatalyst and its formulation and preparation method. By adding photocatalyst materials, the photocatalyst will produce a photocatalytic reaction similar to photosynthesis under the irradiation of light, and gradually generate and release free hydrogen with strong oxidation ability. Oxygen and active oxygen have a strong photoredox function, can oxidize and decompose various organic compounds and some inorganic substances, can destroy bacterial cell membranes and solidify virus proteins, can kill bacteria and decompose organic pollutants, and organic Pollutants are decomposed into non-polluting water (H20) and carbon dioxide (C02), so it has strong functions of sterilization, deodorization, anti-mildew, anti-fouling, self-cleaning, removal of formaldehyde, and air purification. Compared with the non-woven fabric coated with photocatalyst on the outer layer, the photocatalyst of the present invention has a longer release time and a longer sterilizing and purifying function.

Description

technical field [0001] The invention relates to the field of non-woven fabric processing, in particular to a photocatalyst-containing non-woven fabric and its formula and preparation method. Background technique [0002] With the gradual development of the level of industrialization, the pollution of the environment is becoming more and more serious, especially the pollution of the air, which is increasingly affecting our health. The seriously polluted air makes the incidence of respiratory diseases increase day by day, while the existing common Non-woven fabrics and protective masks made of activated carbon non-woven fabrics, the functions of deodorization, self-cleaning and air purification are far from meeting people's needs, so there is an urgent need for a non-woven fabric with excellent self-purification and adsorption functions. Cloth is used to prepare masks with protective functions. Contents of the invention [0003] In order to solve the deficiencies of the pri...
