Abstract

The invention provides a nanometer fabric finishing agent prepared from the following components in percentage by weight: 70-95% of a solvent, 1-10% of a ultraviolet light screening agent, 0.1-10% of a surface treating agent, 0.01-1% of antimicrobial auxiliaries, 0.05-5% of a slurry stabilizing agent and 0.1-10% of a film forming agent. A preparation method of the nanometer fabric finishing agent comprises the following steps: firstly, preparing the solvent; then, sequentially adding the ultraviolet light screening agent, the surface treating agent, the antimicrobial auxiliaries, the slurry stabilizing agent and the film forming agent into the solvent to obtain a mixture; uniformly stirring and dispersing the mixture. The nanometer fabric finishing agent provided by the invention is used for treating the surface of a piece of fabric and ensuring that the fabric has ultraviolet light screening, antimicrobial and anti-mold properties.

Description

technical field [0001] The invention relates to a chemical composition, in particular to a nanometer fabric finishing agent and its preparation method and application. Background technique [0002] With the destruction of the atmospheric ozone layer by human activities, ultraviolet radiation has become one of the great threats to human health, increasing the chance of human beings suffering from skin cancer. Nowadays, the sales of anti-ultraviolet cosmetics and daily necessities have surged, but their protective ability, protective area and action time are limited after all. Therefore, it is an important direction to use textiles with larger area and better protective effect to block the excessive damage of ultraviolet rays to the human body and become a barrier to protect the skin from ultraviolet rays. [0003] According to different protection mechanisms, the types of UV shielding agents used can be divided into two types, one is inorganic UV reflectors, such as titanium...
