| 摘 要： | 壳聚糖与纤维素具有相似的分子结构,可改性制备抗菌纤维素纤维。微晶壳聚糖是壳聚糖的一种形式,具有易粉碎、水相分散稳定等优点,可制得平均粒径1μm的稳定体系,适用于纤维素的粘胶工艺。纺制的壳聚糖/粘胶纤维抗菌性能好,力学和染化性能可达到国家标准(GB/T 13758-92)优等品的要求。2-(2-氨基乙氧基)乙基壳聚糖是一种壳聚糖衍生物,其抗菌性和溶解性均优于壳聚糖,可与纤维素共溶于NMMO溶剂,适于制备抗菌Lyocell纤维。制得的纤维具有良好的力学性能和抗菌性能。

| Abstract: | With similar molecular formula and good antibacterial activity,chitosan suits as antibacterial agent for cellulose fiber.Microcrystalline chitosan,with special structure,can be smashed easily and dispersed steadily in aqueous body.Chitosan/Rayon,which spun from viscose containing microcrystalline chi- tosan with mean diameter 1μm,got good antibacterial activity and physical properties.To get antibac- terial fiber containing chitosan,2-(2-Aminoethoxy)ethylhexyl chitosan (AEECs)was synthesized with better antibacterial activity and solubility than chitosan.From the co-solution of AEECs and cellu- lose in NMMO,a antibacterial Lyocell fiber was spun with satisfying properties. |
