涂层织物耐非水液体性测定方法

Determination for Resistance of Coated Fabric to Non-aqueous Solvents

涂层织物耐非水液体性是涂层织物重要的性能指标之一。通过调研及实验,结合参照其他性能的测定方法,制定了本标准方法。将涂层织物试样浸渍于非水液体中,在室温下处理一定时间后,根据织物被侵蚀的情况评定分级。本法中的非水液体采用四氯乙烯、汽油、丙酮等七种试剂。本法分动态法（A 法）和静态法（B法）两种。

The resistance of coated fabric to non-aqueous solvents is an essential index to evaluate the fabric. On the basis of investigations and experiments along with reference to the testing of the other properties, two standard testing methods covering dynamic analysis (method A) and static analysis (method B) are drafted. During testing, the sample is impregnated in a non-aqueous liquid for a definite time under room temperature. The resistance of coated fabric to non-aqueous solvents used here are gasoline, tetrachloroethylene, acetone, methyl alcohol, methylben-zene,ether and acetic ether.
