Test Method 140-2011
Dye and Pigment Migration in a Pad-Dry
Process: Evaluation of
in 1974 by AATCC Committee RA87
Purpose and Scope
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.
