摘　　要：为赋予Lyocell纤维抗菌性,首先用N-甲基吗啉-N-氧化物(NMMO)水溶液溶解纤维素,制得纤维素含量6%的纺丝液,在纺丝液中添加3,3’,4,4’-二苯甲酮四甲酸二酐(BTDA)与抗菌纳米纤维素,通过干喷湿法纺丝制备抗菌Lyocell纤维。制得的纤维对金黄色葡萄球菌及大肠杆菌抑菌率均达到95%以上。随着BTDA的加入,纤维表面粗糙,断裂强度由62.7 MPa提高至89.1 MPa,断裂伸长率由9.48%降低至5.19%。加入抗菌纳米纤维素的Lyocell纤维力学性能及抗菌性均有提高。由此方法制备的两种抗菌Lyocell纤维耐水洗性能良好。In order to endow Lyocell fibers with antibacterial properties,cellulose was first dissolved in N-methylmorpholine-N-oxide(NMMO)aqueous solution to obtain a spinning solution with 6%cellulose content.3,3ʼ,4,4ʼ-benzophenone tetracarboxylic dianhydride(BTDA)and antibacterial nanocellulose were added to the spinning solution to prepare antibacterial Lyocell fibers by dry-jet wet spinning.The antibacterial rate of the prepared fiber against Staphylococcus aureus and Escherichia coli reached more than 95%.With the addition of BTDA,the surface of the fiber was rough,the breaking strength increased from 62.7 MPa to 89.1 MPa,and the elongation at break decreased from 9.48%to 5.19%.The mechanical properties and antibacterial properties of Lyocell fibers with antibacterial nanocellulose were improved.The two antibacterial Lyocell fibers prepared by this method have good washing resistance.
