摘要
文章测量和分析了几种中长涤粘仿毛机织物在相近厚度、不同透气量以及相近透气量、不同厚度情况下的透湿情况。研究发现,在相近厚度时,织物的静态透湿量随透气量的增大有减小趋势。由此得出一个假设,毛细管吸附作用在织物的静态透湿中起重要作用,透气量太大时单位面积内的毛细孔数减少,对水分子的吸附量小,所以吸湿量小。这个假设被水分蒸发的"量子"跳跃现象所证实。另外,在透气量相近时,透湿量随厚度增加而略有减小,这主要是由于织物微孔中纤维材料的表面积很大,水分子在传递过程中受到很大的吸附力,从而使得较厚织物的导湿能力下降。
The wool-like fabrics with different air-permeability and thickness have been tested for their moisture transmission. Through analyzing the results, it finds that, in static state, the moisture transmission decreases with the increase of air-permeability of fabric. Hence, the hypothesizes is put forward that the moisture transmission of fabric in static state is operate by the ~absorption of the capillary in the fabric. This description has been justified by the phenomenon that the moisture transmission of fabric is in the quantum leap way. In addition, the moisture transmission has been prolong by the fiber in the pores of fabric. Therefore, moisture transmission of thicker fabric is slower.
