摘要
The O-carboxymethyl chitosan sodium salt, NaCMCh, was initially synthesized and analyzed with better antibacterial activity than chitosan. Then NaCMCh was dissolved in the N-methylmorpholine-N-oxide, NMMO, solution with cellulose for spinning of the lyocell fiber. The results showed that the lyocell fibers modified with over 2 wt%NaCMCh has good antibacterial activity in against the E.coli and with NaCMCh content below 6 wt% has considerable mechanical properties.
