英文摘要： In this project, high substantive and permanent effective anti-UV and antimicrobial functional macromolecules are designed and synthesized through the methods of structure modification of benzophenone and benzotriazole-type UV absorbers, grafting, and crosslinking by utilizing the excellent anti-UV performance of UV absorbers, the antimicrobial property and high substantivity to cotton fibers of cationic water-soluble macromolecules and the permanent stability of covalent crosslinking. And the relationship of the structures of the functional macromolecules and their properties and application were studied. In the project, the pertinence of the modified UV absorbers and their reactivity and anti-UV performance have been specified; the effect of the polymerization methods on the properties of the functional macromolecules was summarized; the change rule of the anti-UV properties of the macromolecules was determined and the antimicrobial properties were explored. The research showed that the fastness properties of the finished cotton fabrics with the macromolecular agents were excellent by utilizing supra-molecular interaction and multi-spot complex crosslinking between the agents and cotton fibers. It provides new notion for establishing finishing system of cotton and other fibers with functional macromolecules.
