1.目的和范围1。1本试验方法可用于通过评估织物对不同表面张力的选定系列水/酒精溶液的润湿性，来确定能够在所有类型织物上赋予低能表面的保护性整理剂的功效。2.原则2。1.在织物表面滴入由一系列水/乙醇溶液组成的标准测试液，溶液的表面张力不同，观察其润湿性、芯吸性和接触角。

1. Purpose and Scope1.1 This test method can be used to determine the efficacy of a protective finish that is capable of imparting a low energy surface on all types of fabrics, by evaluating the fabric's resistance to wetting by a selected series of water/alcohol solutions of different surface tensions.2. Principle2.1 Drops of standard test liquids, consisting of a selected series of water/alcohol solutions with varying surface tensions, are placed on the fabric surface and observed for wetting, wicking and contact angle.
