Abstract

The invention discloses an ultraviolet-resistant fabric and a preparation method thereof. The fabric comprises a fabric surface layer and an ultraviolet-resistant layer deposited on the fabric surface layer, wherein the ultraviolet-resistant layer is a blending layer of polyurethane, sodium alginate, hydroxyethyl methyl cellulose, hindered amine light stabilizers, hydroxyphenyl benzotriazole ultraviolet absorbents, nano ultraviolet absorbents and rare earth fluorescent compounds. The fabric is excellent in ultraviolet-resistant effect, excellent in moisture absorption property, simple in production process, has resistance to sunlight and perspiration and does not need to be washed with water; a lot of water and energy can be saved; the fabric coated with the ultraviolet-resistant coating is soft, tough, washable and durable, and is excellent in properties.

Description

technical field [0001] The invention relates to a fabric, in particular to an anti-ultraviolet fabric and a preparation method thereof. Background technique [0002] A large amount of data shows that ultraviolet radiation will not only harm plants and animals on the earth, but also the main cause of human skin cancer. The ozone layer is the protective layer of the atmosphere, but it has been thinning in recent decades, and even has holes, reaching the surface of the earth. The amount of solar ultraviolet radiation is increasing, so it is imminent to study and find ways to effectively protect the human body from ultraviolet rays. In this case, various sun protection products, such as sun protection clothing, parasols, beach facilities, tents, etc., have proposed anti-ultraviolet requirements. However, fabrics made of natural fibers or conventional chemical fibers generally cannot meet the requirements for anti-ultraviolet radiation. Therefore, research and development of a p...
