AATCC TM140-2018e, Dye and Pigment Migration in a Pad-Dry Process
Developed in 1974 by AATCC Committee RA87; reaffirmed 1976, 1977, 1980, 2006, 2011; editorially revised and reaffirmed 1985, 1990, 2001; editorially revised 1987, 1991, 1998, 2010, 2019 (with title change); revised 1992, (with title change), 1996 (with title change), 2018. Technically equivalent to ISO 105-Z06.
1. Purpose and Scope
1.1 This test method provides a means of assessing the migration propensity of a pad liquor system containing dyes or pigments, subsequently referred to as colorants, and which may also contain different types and amounts of migration inhibitors.
1.2 When drying conditions are not constant and/or uniform, uneven migration may occur, causing shade variations during a run, or shade differences between the face and back, or between side and center of the fabric.
