摘　　要：制备不同石墨烯含量的石墨烯改性黏胶长丝,并测试对比其形态结构及性能。详细介绍原料选择、纤维成形工艺、石墨烯选择、共混纺丝液性能测试、石墨烯改性黏胶长丝制备工艺及在针织方面的应用。结果表明:由机械剥离法制备的石墨烯与黏胶纺丝液共混后共混纺丝液的熟成度及黏度变化趋势与常规黏胶纺丝液接近;不同片径的石墨烯对黏胶纺丝液的过滤性能有影响,选用片径≤0.3μm的石墨烯可满足纺丝需求;石墨烯改性黏胶长丝具有良好的抗菌性能,对白色念珠菌、金黄色葡萄球菌、大肠杆菌的抑菌率均超过国家标准要求。Graphene modified viscose filament with different graphene contents were prepared,and their morphology,structure and properties were tested and compared.The selection of raw materials,fiber forming process,graphene selection,properties testing of blend spinning liquid,preparation process of graphene modified viscose filament and its application in knitting were introduced in detail.The results show that the ripening degree and viscosity change trend of the graphene and viscose spinning solution were close to that of the conventional viscose spinning solution.Different particle sizes of graphene affect the filtration performance of viscose spinning liquid.It is proved that graphene with particle size≤0.3μm can meet the spinning requirements.The graphene modified viscose filament has good antibacterial properties,and the antibacterial rate to candida albicans,staphylococcus aureus and escherichia coli exceeds the national standard.
