YG461型织物透气仪的中压标定及织物透气量的探讨

Discuss on the medium pressure colibration of the instrument YG461 and the permeability of fabrics

本文主要论述了国产 YG461型织物透气仪的测试原理 ,并在中压条件下对不同透气量织物的透气性进行了大量的测试 .同时以实验数据为依据 ,给出了两室压差及透气量的数值对应形式的查数表供测试者使用 ,并对不同层数织物的透气量进行了相关分析 .

This paper mainly discusses the testing theory of the instrument for permeating air of fabrics (YG461),and under the medium pressure,a large number of experiments are done for permeability of different fabrics.At the same time,we offer testers the inquiry table of pressure difference and permeability of fabrics according to the experimental data so that testers can use it conveniently,and analyse the relations between various layers of fabrics and quantities of permeating air.
