摘　　要：为了提高涤纶织物的单面亲水性,通过静电纺丝法直接将聚乙烯醇(PVA)/海藻酸钠(SA)电纺纤维沉积在涤纶织物表面。讨论了PVA质量分数、SA质量分数、PVA和SA体积比、静电纺丝时间对电纺纤维形貌、改性涤纶织物亲水性能、抗静电性能、力学性能和透气性能的影响。结果表明,当PVA与SA质量分数分别为10%和2%,PVA与SA体积比为9∶1时,织物表面形成的电纺纤维分布均匀。改性涤纶织物的亲水性能和抗静电性能显著增强;断裂强度和断裂伸长率得到提高;并且保持了织物原有的柔软性。增加电纺时间,改性涤纶织物的力学性能没有明显变化,但电纺纤维层的形成导致改性涤纶织物的透气性能显著降低。In order to improve the hydrophilicity of polyester fabric, polyvinyl alcohol(PVA)/sodium alginate(SA) electrospun (E-spun) fibers was deposited directly on the surface of polyester fabric by electrospun method. The effects of polyvinyl alcohol concentration, sodium alginate concentration, volume ratio of polyvinyl alcohol and sodium alginate, and E-spun time on the morphology of E-spun fibers, modified polyester fabric(M-PET)′s hydrophilicity, antistatic property, air permeability and mechanical properties were discussed. The results show that when the PVA(10%)∶SA(2%)=9∶1, the E-spun fiber on the modified polyester fabric has uniform distribution morphology. The hydrophilicity and antistatic properties of modified polyester fabric increase considerably. Elongation at break and breaking force of the modified polyester fabric are enhanced,and its softness is maintained. Further increasing E-spun time has no obvious alterations in the mechanical properties. However, the formation of E-spun fiber layer lead to a significant decrease in the air permeability of modified polyester fabric.
