Abstract

The invention discloses a method for realizing a textile intelligent cleaning function through a crosslinking temperature-sensitive copolymer. The method comprises the following steps of (1) using the temperature-sensitive copolymer, a crosslinking agent, a catalyst and a solvent to process a textile; (2) carrying out crosslinking reaction on the processed textile through heating and baking. According to the method for realizing thetextile intelligent cleaning function through the crosslinking temperature-sensitive copolymer provided by the invention, the cleaning efficiency of the textile during the washing process is improved, and the self-cleaning effect is achieved during the wearing process; the operation can be carried out conveniently without influencing the original whiteness and flexibility; a covalent bond is formed through reaction of a reactive functional group contained in an acrylate monomer with the reactive functional group at the tail end of a side chain in the temperature-sensitive copolymer and a reactive functional group on the surface of the textile with carboxyl contained in the crosslinking agent, and the temperature-sensitive copolymer is fixed on the surface of the textile, so that the modified textile has a function of hydrophily / hydrophobicity intelligent adjustment.

Description

technical field [0001] The invention relates to a method for realizing the intelligent cleaning function of textiles through a cross-linked temperature-sensitive copolymer. Specifically, it refers to cross-linking temperature-sensitive copolymers on the surface of textiles, using the characteristics that temperature-sensitive copolymers can independently undergo hydrophilic / hydrophobic transitions according to changes in the external environment temperature, so as to achieve a temperature lower than the transition temperature (TT) of the temperature-sensitive copolymers. ), such as in the textile washing process, the copolymer is in a hydrophilic state, and the textile has an excellent cleaning effect; when the temperature is higher than TT, such as in the daily wearing process, the copolymer is in a hydrophobic state, and the textile has a good self-cleaning effect, Therefore, the function of intelligently adjusting the performance of textiles according to different external ...
