▎ 摘　　要

NOVELTY - Down garment fabric with ultraviolet color-changing coating comprises a fabric main body and ultraviolet color-changing coating coated on surface of fabric main body, the ultraviolet color-changing coating comprises 90-95 pts. wt. aqueous polyurethane, 12-25 pts. wt. carbon diacetylene acid, 0.5-1 pts. wt. nano graphene oxide, 5-10 pts. wt. coupling agent, 5-10 pts. wt. antioxidant and 200-250 pts. wt. distilled water. USE - Down garment fabric with ultraviolet color-changing coating. ADVANTAGE - The UV color-changing coating has very uniform color changing effect after long-time cleaning and use, strong UV color changing ability, and long action time, cleaning and abrasion resistance. The method is simple and cost-effective. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a down clothes fabric with ultraviolet color-changing coating, involving: a. using the textile device to prepare the down fabric; b. preparing ultraviolet color-changing paint by mixing carbon diacetylenic acid, nano graphene oxide and coupling agent, stirring to obtain mixture A; c. adding the mixture A into the aqueous polyurethane, after reacting under stirring, then adding antioxidant continuously stirring to obtain the mixture B; d. adding the distilled water into the mixture B to obtain ultraviolet color-changing coating; and e. coating the ultraviolet color-changing coating on the surface of the fabric main body, drying to obtain product.
