不同细度羊毛的吸湿性能研究

Study of moisture absorption property of the wool with different finess

通过对66、80、90、100支不同细度羊毛做吸湿、放湿实验,得出不同细度羊毛的吸湿放湿曲线及拟合方程,通过统计与计算可以得出支数越高,纤维越细,则纤维的吸湿回潮率、放湿回潮率均提高,且每种纤维的放湿回潮率均大于吸湿回潮率;在吸湿的起始阶段纤维越细吸湿速率越大,经过一段时间后,较粗纤维吸湿速率大于较细纤维的吸湿速率;在放湿过程中,100支羊毛的放湿速率由开始阶段的最慢变为一段时间后的相对最快。

Through the moisture absorption and desorption experiments for the 66, 80, 90 and 100 S wool, it gots the moisture absorption and desorption curve and the fitting equation. Through statistical and compute it, the result that higher quality, finer fiber, and the moisture absorption and desorption regain rate were all increased, and the desorption regain rate of each fiber were greater than the absorption regain rate. The finer fibers＇ rate of the moisture absorption in the initial stage was greater, and through period of time, coarse fibers＇ moisture absorption rate was greater. In the desorption process, in the initial stage 100 S wool fibers＇ desorption rate was the slowest, and through period of time it was the fastest.
