Abstract

The invention discloses an ultraviolet-resistant modified fibrilia fabric and a preparation method thereof. The preparation method of the ultraviolet-resistant modified fibrilia fabric includes: processing fibrilia fabric with a microbial modifier, and processing the modified fibrilia fabric with ultraviolet resisting ingredients. The microbial modifier comprises acidothermus, white rot fungi andacetobacter xylinum. The ultraviolet resisting ingredients comprise silk fibroin peptide and nanometer titania. The ultraviolet-resistant modified fibrilia fabric has the advantages that active groupsobtained from microbial biochemical reaction on the modified fibrilia fabric can be linked with the ultraviolet resisting ingredients, so that ultraviolet resistance of the fibrilia fabric can be improved remarkably, the active groups and the ultraviolet resisting ingredients are less prone to falling, and the modified fibrilia fabric can be applied in every field of textile and costume.

Description

technical field [0001] The invention relates to the technical field of textile products, in particular to an anti-ultraviolet modified hemp fiber fabric and a preparation method thereof. Background technique [0002] Hemp fiber is cellulose fiber, the basic chemical composition is cellulose, the content is about 75%, and other non-fibrous substances such as pectin, hemicellulose, lignin, fat wax. Cellulose is a natural polymer compound. The chemical structure of cellulose is composed of α-glucose as the basic structural unit, and its elemental composition is 44.44% carbon, 6.17% hydrogen, and 49.39% oxygen. The degree of polymerization of ramie fiber is between 2000 and 2500. Because hemp fiber is a natural material, its fabric has no stimulation and no side effects when in contact with the skin. Long-term wear is beneficial and harmless to the human body. The thermal conductivity is small so that the fabric has better thermal performance; the dyeing performance of the lin...
