NOVELTY - Use of Smilax miltiorrhiza root extract in the preparation of anti-ultraviolet finishing agent, enhancing the anti-ultraviolet effect of the anti-ultraviolet finish, where cinnamic acid modified nano-titanium dioxide graphene composite is used as the main anti-ultraviolet component is claimed. USE - Smilax miltiorrhiza root extract in the preparation of anti-ultraviolet finishing agent, enhancing the anti-ultraviolet effect of the anti-ultraviolet finish, improving the washfastness of the ultraviolet-resistant finish, improving the ultraviolet-aging resistance of the ultraviolet-resistant finish, improving mechanical strength of fabrics finished with the UV-resistant finish, for use in anti-ultraviolet functional fabric (all claimed). ADVANTAGE - The root extract for use in the preparation of fabric finished with the anti-ultraviolet finishing agent has excellent mechanical strength and anti-ultraviolet performance, and at the same time, the anti-ultraviolet performance has good washing fastness and anti-ultraviolet aging resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) an anti-ultraviolet finishing agent, which comprises sarsaparilla root extract and modified nano-titanium dioxide graphene composite, and Smilax miltiorrhiza root extract is an aqueous phase concentrate that is dispersed in water after the smilax miltiorrhiza root is extracted with high concentration ethanol, and the modified nano-titania-graphene composite is a cinnamic acid-modified nano-titania-graphene composite; (2) a preparation method of the UV-resistant finishing agent, which involves: (a) uniformly dispersing Smilax root extract and cinnamic acid-modified nano-titanium dioxide-graphene composite in some solvents to obtain liquid A; (b) uniformly dispersing other components in the remaining solvent to obtain liquid B; (c) adding solution A to solution B slowly and mixing well; (3) an anti-ultraviolet functional fabric, which is surface-treated by the anti-ultraviolet finishing agent.
