AATCC Test Method 119-2013

Color Change Due to Flat Abrasion (Frosting):

Screen Wire Method

Developed in 1967 by AATCC Committee RR29 (Editorially Revised and Reaffirmed 2013)

1.  Purpose and Scope

1.1  This test method is intended for evaluating the resistance of colored fabrics to change in shade caused by flat abrasion.  It can be used for all colored fabrics, but is especially sensitive to the colored fabrics, but is especially sensitive to the color change of durable press cross-dyed blend fabrics, in which one fiber is abraded away faster than the other.
1.2  The test method produces in an accelerated manner, a localized color change similar to that produced on some garments over relatively short periods of actual wear in which the garment is exposed to relatively mild abrasive action.

2.  Principle

2.1  The fabric specimen is mounted over a foam rubber cushion and rubbed multidirectionally against a wire screen mounted on a weighted head.  Any change in the color of the specimen is evaluated by comparison with the Gray Scale for Color Change.
