AATCC TM159-2017e, Transfer of Acid and Premetallized Acid Dyes on Nylon

Developed in 1979 by AATCC Committee RA87; editorially revised and reaffirmed 1984, 1989 (title change), 1994, 1999; editorially revised 1985, 1987, 1997, 2004, 2010, 2019; reaffirmed 2006; revised 2011, 2017.

1. Purpose and Scope

1.1 This test method evaluates the transfer of acid (anionic) or premetallized dye from a dyed to an undyed nylon substrate under mock dyebath conditions. A general method of dyeing acid dyes on nylon is included for uniformity of dyeing procedure.

2. Principle

2.1 A test specimen of nylon fabric is dyed to 1/1 standard depth with the dye to be evaluated. Part of the dyed fabric together with an equal weight of undyed fabric is subjected to transfer in a mock dyebath.

2.2 Transfer is made at pH 4.5, 6.0 and 7.5, and at a temperature of 95ÁC.
