摘　　要：文中对国标中纺织品水分蒸发速率的测试方法进行了探讨。指出:水分蒸发速率试验应与滴水扩散时间试验分别取样测试;另外,应使用固定0.2 mL移液器快速准确滴取0.2 mL三级水;自制了关于水分蒸发速率的测试装置;并建议采用SLOPE函数和STDEVP函数在Excel软件中绘制水分蒸发速率曲线,以STDEVP函数计算出的总体标准偏差来筛选趋近于直线部分的点。结果表明,所建议的测试方法可行性高,且对于同一试样测试结果的重现性好。Testing methods of textile moisture evaporation rate are investigated in this article. It points out that the samples for the experiment of textile moisture evaporation rate and for the experiment of water diffusion time should be prepared separately; meanwhile, 0.2 mL of pipette should be used to drop 0.2 mL of three grade water accurately and quickly. The devices for testing textile moisture evaporation rate are self-made; it is suggested that Excel software along with SLOPE function and STDEVP function should be used to draw curves of textile moisture evaporation rate, to be specific, standard deviation in population from STDEVP function is used to choose the spots where are tended to be straight. The results show that the suggested testing methods have high feasibility for differ- ent kind of samples and high reproducibility for the same kind of samples.
