Temperature-sensitive type finishing agent as well as preparation method and applications thereof

Abstract

The invention discloses a temperature-sensitive type finishing agentas well as a preparation method and the applications thereof. The finishing agent mainly contains a copolymer formed by an N-alkyl acrylamide monomer and a functional monomer, has favorable temperature sensibility and reaction activity and can further react with crosslinkers (isocyanates, melamines or epoxies) when applied to textile finishing. The method is simple and practical, and the textiles have temperature sensibility, easy decontamination function at a low temperature and favorable durability.

Description

technical field

[0001] The invention belongs to the field of intelligent textile finishing, and in particular relates to a temperature-sensitive finishing agent and a preparation method and application thereof. Background technique

[0002] People have found that some gels will undergo reversible and discontinuous abrupt changes in their volume, strength, and hydrophilicity with changes in the environment such as temperature, pH, ionic strength, electric field, and light. Gels are known as environmentally sensitive gels. Therefore, there are many studies on polymers or their hydrogels with environmental responsiveness, especially temperature and pH responsiveness, and have been applied in the fields of drug controlled release, enzyme immobilization, separation and adsorption, and sensors. Similarly, this environmentally responsive substance has also been studied in the field of textiles. People hope to combine this environmentally responsive substance with textiles to obtai...
