AATCC TM22, Test Method for Water Repellency: Spray t

 

Developed in 1941 by AATCC Committee RA63 (revised 2017).

 

1.  Purpose and Scope

 

1.1  This test method is applicable to any textile fabric, which may or may not have been given a water-repellent finish.  It measures the resistance of fabrics to wetting by water.  It is especially suitable for measuring the water-repellent efficacy of finishes applied to fabrics.

 

2.  Principle

 

2.1  Water sprayed against the taut surface of a test specimen under controlled conditions produces a wetted pattern whose size depends on the relative repellency of the fabric.  Evaluation is accomplished by comparing the wetted pattern with pictures on a standard chart.
