Abstract

The invention relates to the technical field of improvement of ultraviolet resistance of silk fabrics, and particularly discloses application of camellia pigment to improvement ofultraviolet resistance of a silk fabric, the application is realized in a mode of dyeing the silk fabric through the camellia pigment, the dyeing method comprises the following steps: dissolving the camellia pigment in water, adjusting the pH range to be acidic, and then dip-dyeing the silk fabric to obtain the camellia dyed fabric. The camellia pigment is mainly applied to the field of food additives and brings natural color and safety. The inventor finds that the camellia pigment not only is firm in color, but also can enhance the ultraviolet resistance of the silk fabric in the research of dyeing the silk fabric by using the camellia pigment.

Description

technical field [0001] The invention relates to the technical field of improving the anti-ultraviolet ability of silk fabrics, in particular to the application of camellia pigment in improving the anti-ultraviolet ability of silk fabrics. Background technique [0002] Silk fabrics have good skin-friendly skin care properties for the human body, which is mainly due to the fact that the main components of silk are silk fibroin and sericin. Among them, sericin is a protein that constitutes the outer layer of silk fiber, which has affinity to the human body, natural moisturizing properties, antioxidant properties, antibacterial, antistatic effects, and safety and no side effects; the helical protein structure of silk fibroin contains affinity The water base not only absorbs water, but also forms a film to reduce water loss. The ethylene chloride in the silk peptide of silk fibroin will undergo photochemical reaction when it encounters ultraviolet rays, which can block the damag...
