摘　　要：采用壳聚糖纤维和聚酯纤维为原料,通过针刺工艺制备梯度结构的壳聚糖纤维敷料样品,并对样品的形态结构、吸液率和液体扩散特性进行观测,结果表明,随着保湿层中壳聚糖纤维质量分数从50%增大到70%,样品的吸液率从2 035%增大到2 232%;样品被液体浸润后,壳聚糖纤维形成凝胶并黏附于聚酯纤维表面,而聚酯纤维的三维杂乱排列结构为凝胶提供骨架支撑;样品与棉织物的液滴扩散面积有差异,表明壳聚糖纤维被液体浸润后形成凝胶,可以有效缩小液体在保湿层上的扩散面积。Chitosan fibers and polyester fibers were used as raw materials to prepare the samples of chitosan fibrous dressings with gradient structure by needle punching process.The morphological structure,liquid absorption and liquid diffusion properties of the samples were observed and tested.The results showed that,the liquid absorption rate increased from 2 035%to 2 232%as the mass ration of chitosan fibers in the moisturizing layer increased from 50%to 70%.After the samples were infiltrated by liquid,the chitosan fibers formed gels,which adhered to the surface of polyester fibers.The three-dimensional disordered arrangement structure of polyester fibers provided the framework support for the gels.The diffusion area of the samples and that of cotton fabrics were different,which showed that chitosan fibers formed gels after being infiltrated by liquid,which could effectively reduce the diffusion area of liquid on the moisturizing layer.
