织物透气性两种计算方法的对比

Comparison of Two Calculation Methods for Textile Air-permeability

文中对织物透气量的两种计算方法进行了对比分析。以压差式织物透气仪——IT-1型织物透气性测试仪为测试工具,分别采用公式计算和数据拟合两种方法对织物的透气量进行测定与计算。结果表明:这两种方法虽然是不同的数学方法,但测试结果相差不大,最大偏差仅为3.0%,说明这两种测试方法均是可行的。

In this paper, two calculation methods of textile air permeability are comparatively analyzed. Using differential pressure permeometer IT-1 type permeometer as testing tool, textile air permeability are calculated by formula-based computing method and data fitting method, respectively. The resuhs show that although these two methods are different, testing results between them are nearly the same and the maximum deviation is only 3%, which suggest that both of the two calculation methods are feasible.
