Synthesis of thermosensitive hydrogels and the application to breathable finishing of cotton fabric
Macromolecular dienes compounds is synthesized with polyethylene glycol and maleic anhydride as raw materials,and is used as cross-linking agent for the preparation of thermosensitive hydrogel poly (N-isopropylacrylamide) (PNIPAM) with net-like structure.The PNIPAM is applied to cotton fabric with pad-dry-crue process,the effect of type and amount of cross-linking agent on the size of PNI-PAM and the breathability of cotton fabric are investigated.The results show that PNIPAM can improve the breathability of cotton fabric under the controlled temperature.The moisture absorption and swelling ratio,as well as the breathability of the treated fabric are the best when thermosensitive hydrogel is synthesized with MA-PEG600-MA as cross-linking agent.
