羽绒纤维的吸湿性能

 羽绒单纤维的吸湿性对羽绒纤维和纤维集合体的热性能有很大的影响。主要讨论影响羽绒单纤维吸湿性能的主要因素,通过实验测试羽绒在不同情况下的吸湿性,并与其它天然纤维和合成纤维进行对比,分析纤维间产生这种吸湿性差异的本质原因。最后,利用Hailwood和Horrobin的吸湿理论,结合实验数据,总结建立了羽绒纤维吸湿性的等温模型。

Absorbent quality of down fibers

The absorbent quality of single down fibers has great impact on the thermal property of down fiber assembly. This paper discussed the primary factors affecting the absorbent quality of down, and tested its absorbent quality under different conditions. Through comparing with other natural fibers and synthetic fibers, the different absorbent qualities from fiber to fiber and the reason of producing this phenomena were expatiated. Finally, an absorbent quality isothermal model of down fibers was developed according to the Hailwood-Horrobin theories in combination with the experimental data.
