摘　　要：为设计开发新型医用非织造绷带,以涤纶和黏胶为原料,制备不同纤维原料配比和经不同工艺处理的非织造绷带基布。对非织造绷带基本进行表面形貌观察,并对其厚度、透气性、拉伸性能、顶破性能、弯曲性能、亲水性能及液体扩散性能进行测试分析。结果表明,60%黏胶/40%涤纶半交叉铺网非织造绷带基布和100%涤纶上浆半交叉铺网非织造绷带基布的综合性能更好,前者抗弯刚度达0.24 mN·cm,透气量达551 mm/s,断裂伸长率为51.60%;后者透气量达601 mm/s,断裂伸长率达83.94%,两者均适用于制作医用非织造绷带。In order to design and develop new medical non-woven bandages,polyester and viscose were used as raw materials to prepare non-woven bandage base fabrics with different raw material ratios and different treatment processes.The surface morphology of non-woven bandage base fabrics was observed,and their thickness,air permeability,tensile property,bursting property,bending property,hydrophilic property and liquid diffusion property were tested and analyzed.The results show that the 60%viscose/40%polyester semi-cross-layed non-woven bandage base fabric and 100%polyester semi-cross-layed non-woven bandage base fabric after sizing have better comprehensive properties.The former has a flexural stiffness of 0.24 mN·cm,a air permeability of 551 mm/s,and a elongation at break of 51.60%.The latter has a air permeability of 601 mm/s and a elongation at break of 83.94%.Both of the two are suitable for making medical non-woven bandages.
