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 photocatalyst and a formula and a preparation method thereof. Under the irradiation of light, the added photocatalyst generates photocatalytic reaction similar to photosynthesis, and gradually produces and releases free hydrogen group with strong oxidation ability and reactive oxygen. The photocatalyst has strong light redox function, can oxidize and decompose various organic compounds and some inorganic substances, damage cell membranes of bacteria, cure viral proteins, kill bacteria, and break down organic pollutants into non-polluting water (H2O) and carbon dioxide (CO2); therefore, the photocatalyst has extremely strong bactericidal, deodorant, anti-mildew, anti-fouling, self-cleaning, formaldehyde removal and air purification functions. Compared to the non-woven fabric with photocatalyst coated on the outer layer, the photocatalyst of the invention has more lasting release time and more permanent sterilization purification function.

Description

Technical field [0001] The invention relates to the field of non-woven fabric processing, in particular to a non-woven fabric containing a photocatalyst and its formula and preparation method. Background technique [0002] With the gradual development of industrialization, environmental pollution has become more and more serious, especially atmospheric pollution, which is increasingly affecting our health. The severely polluted air makes the incidence of respiratory diseases increasing, while the existing ordinary Non-woven fabrics and protective masks made of activated carbon non-woven fabrics have deodorizing, self-cleaning and air purification functions far from meeting people’s needs today, so there is an urgent need for a non-woven with excellent self-purification and adsorption functions. Cloth to prepare protective masks. Summary of the invention [0003] In order to solve the shortcomings of the prior art, the present invention provides a photocatalyst-containing non-wove...
