Abstract

The invention relates to the technical field of textile fabrics, and particularly relates to an anti-ultraviolet textile fabric comprising a textile layer and an anti-ultraviolet coating layer coated on the textile, wherein the anti-ultraviolet coating layer comprises the following components in parts by weight: 30-35 parts of unsaturated polyester, 20-25 parts of hydroxyl-terminated polymethyl silicone oil, 2-5 parts of polyvinylpyrrolidone, 3-8 parts of an organic silicon emulsion, 0.1-0.5 part of a modified or unmodified melanin powder, 3-8 parts of a modified sea-foam stone powder, 0.2-0.5 part of titanium dioxide, 3-7 parts of lactide, and 5-20 parts of a solvent. The fabric is high-temperature-resistant, has good aging resistance, high structural strength and excellent toughness, can be used for a long time under direct sunlight, and has a good ultraviolet blocking effect for a long time.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to an ultraviolet-resistant textile fabric. Background technique [0002] Since the main part of solar ultraviolet radiation is absorbed by molecules such as ozone, oxygen and nitrogen in the atmosphere, ultraviolet radiation has been greatly weakened on the earth's surface. However, in recent years, a large amount of fluoride gas represented by Freon has been emitted, and the atmospheric ozone layer has been irreversibly damaged, thereby weakening the ozone layer's ability to filter and block ultraviolet rays. Scientific studies have shown that the destruction of the ozone layer is one of the main reasons for the rising incidence of human skin cancer. Because ultraviolet radiation will change the structure and function of cell components, when the cells are saturated with ultraviolet radiation, the cells will lose the ability to communicate with other cells and undergo apo...
