Problems solved by technology

[0002] The nano-anti-ultraviolet finishing agent uses a light-resistant stabilizer as the base material, and the light stabilizer enters the fiber in the form of nanoparticles through the baking method and is fixed on the fiber, so that the fabric has excellent anti-ultraviolet performance; the traditional anti-ultraviolet finishing agent uses nano The material is directly synthesized, which reduces the anti-ultraviolet performance, does not have antibacterial properties, is not conducive to user use, and is troublesome to make, time-consuming and laborious, which is not conducive to user production. At the same time, the raw materials of traditional anti-ultraviolet finishing agents are expensive, which increases production costs and is not conducive to processing and production; For these defects, it is necessary to design a preparation method of chitosan-based anti-ultraviolet finishing agent
