| 摘 要： | IntroductionThe spinning of cellulose fibers directly from asolution, e .g .N-methyl morpholine-N-oxide , NMMO,isusually regarded as the lyocell fiber . Generally ,this lyocellprocess is environmentally friendly and the fiber isbiodegradable with good physical properties and mechanicalparameters . However , several attempts have been madeable to modify the lyocell fibers with novel properties ,e .g .by adding other polymers in the process to change itsstructure and properties1,2].Chitosan …

| Abstract: | The O-carboxymethyl chitosan sodium salt, NaCMCh, was initially synthesized and analyzed with better antibacterial activity than chitesan. Then NaCMCh was dissolved in the N-mcthylmorpholine-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. |
