Abstract:

Antimicrobial chitosan guanidine hydrochloride was synthesized by reacting chitosan guanidine sulfite with concentrated hydrochloric under microwave irradiation. The structures of guanidinylated chitosan were characterized by FT-IR and 13CNMR. Chitosan guanidine hydrochloride was applied to the antimicrobial finishing of  wool fabric and the the infouences of finishing conditions including antimicrobial agent mass concentration, curing temperature and curing time on the antimicrobial effect and physical mechanical properties were researched. The results show that antimicrobial chitosan guanidine hydrochloride was synthesized successfully under microwave irradiation. The optimal procedure parameters for finishing agent on wool fabric are as followed: mass concentration of chitosan guanidine hydrochloride of 10g/L, curing temperature of 130℃ and curing time of 5min.

Key words: chitosan guanidine hydrochloride, wool, antimicrobial finishing, microwave irradiation
