为推动再生纤维素纤维的多样化,研究新开发新丽赛纤维的形态结构与性能指标,采用扫描电镜、X射线衍射仪、电子单纤维强力仪、纤维比电阻测试仪等仪器,对比分析新丽赛纤维、粘胶纤维及原丽赛纤维的表面形态、结晶度、力学性能、摩擦性能、回潮率、抗静电性能、抗菌性能、耐碱性能等指标.指出:新丽赛纤维继承了原丽赛纤维良好的可纺性及优良的服用性能,纤维生物可降解;力学性能优于粘胶纤维,手感柔软,适合开发针织面料;结晶度介于粘胶纤维与棉纤维之间,强度高,吸湿性好,可应用于非织造布领域;抗菌性、耐碱性优良,可与棉混纺进行丝光处理.
In order to promote the diversification of regenerated cellulose fibers,the morphologi-cal structure and performance indexes of newly developed new richcel fiber are researched,the surface morphology,crystallinity,mechanical properties,friction properties,moisture regain,antistatic properties,antibacterial properties and alkali resistance of new richcel fiber,viscose fi-ber and original richcel fiber are compared and analyzed by using scanning electron microscope,X-ray diffraction,electronic single fiber tensile tester,fiber specific resistance meters and other instruments.It is pointed out that the new richcel fiber inherits the good spinnability and wear-ability of the original richcel fiber.The new richcel fiber is biodegradable,soft feel,is suitable for the development of knitted fabrics,and has better mechanical properties than viscose fiber.The crystallinity of new richcel fiber is between viscose fiber and cotton fiber.New richcel fiber has high strength,good moisture absorption,excellent antibacterial,alkaline resistance,and can be used in the field of nonwoven fabrics and blended with cotton for mercerizing treatment.
