摘要
为研究木棉纤维润湿、吸湿及织物湿传递性能,对木棉纤维接触角、表面自由能、吸放湿回潮率及含木棉纤维织物的芯吸高度、水扩散面积等指标进行了测试分析。结果表明,木棉纤维和棉纤维对去离子水的静态接触角都较大,表面润湿性差,两种纤维都属于低能表面材料,木棉纤维极性分量较棉纤维略小,表面疏水性略强。木棉纤维吸、放湿曲线规律与棉纤维相似,前者的回潮率和吸、放湿速率及吸、放湿性均较棉纤维好。木棉含量高时织物芯吸高度大,扩散面积大,并且二者均与木棉纤维含量呈线性相关,含木棉织物较棉织物具有更好的液态水传递性能。
In order to investigate wettability, moisture absorption and moisture transfer property of kapok fiber fabric, the contact angle, surface free energy, moisture regain of kapok fiber and wicking high, water diffusion area of fabric with kapok fiber are tested and analyzed. The results show that kapok fiber and cotton fiber have poor surface wettability with high static contact angle for deionized water, they both belong to low surface energy materials, but kapok fiber is more hydrophobic than that of cotton fiber, and its polarity component is smaller than that of cotton fiber. Kapok fiber and cotton fiber are similar in the sorption and desorption curves, but the hygroscopicity of the kapok fiber is better, and its moisture regain and the rate of sorption and desorption are higher. Compared with cotton fiber, kapok fiber fabrics have better moisture transfer property, and kapok fiber content demonstrates good linear relationship with diffusion areas and wick high.
