The structures of the salt was fully characterized by using FTIR, 1 H-N-MR and ^13C-NMR analysis. The effects of pH conditions of finishing baths, finishing time and temperature, and salt concentrations were investigated. ALPC could form ionic interactions with anionic groups on wool, which contribute to durable antimicrobial functions. The finished wool fabrics exhibited antimicrobial efficacy against Escherichia coll. The washing durability of antimicrobial functions on the finished wool fabrics was also studied.展开更多

Its tensile strength was 8.6MPa(wet state)and degree of swelling water was 60%～75% with higer ultimate elongation 300%. Rabbit corneas of collagen chitosan/GAG implantation samples in vivo for biodegradation showed that the inplantion samples was complets biodegrable and digested afere 120 day. There was enought time to maintain cell growth,immigrating and proliferation. This biomaterials scaffold can be used for cell culture and in various tissue engineering fields.展开更多
