AATCC TM193, Aqueous Liquid Repellency: Water/Alcohol Solution Resistance Test

Developed in 2004 by AATCC Committee RA56 (reaffirmed 2012, 2017; editorially revised 2017; revised 2023).

1.  Purpose and Scope

1.1  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 fabricÕs resistance to wetting by a selected series of water/alcohol solutions of different surface tensions.

2.  Principle

2.1  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.
