AATCC TM140-2011, Dye & Pigment Migration in a Pad-Dry Process: Evaluation of
Developed in 1974 by AATCC Committee RA87 (reaffirmed 2011)
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.
