AATCC Test Method 61-2013
Colorfastness to Laundering:  Accelerated

Developed in 1950 by AATCC Committee RA60 (Revised 2013)


1.  Purpose and Scope

1.1  These accelerated laundering tests are to evaluate the colorfastness to laundering of textiles which are expected to withstand frequent laundering.  The fabric color loss and surface changes resulting from detergent solution and abrasive action of five typical hand or home launderings, with or without chlorine, are roughly approximated by one 45 min test.

2.  Principle

2.1  Specimens are tested under appropriate conditions of temperature, detergent solution, bleaching and abrasive action such that the color change is similar to that occurring in five hand or home launderings.
