AATCC TM161-2023, Color Change of Disperse Dyes Caused by Metals, with and without Chelating Agent

Developed in 1983 by AATCC Committee RR90; editorially revised 1985, 1988 (with title change), 2005, 2008, 2010, 2019; editorially revised and reaffirmed 1986, 1987, 1993, 2002, 2012; reaffirmed 2007; revised 2018, 2023..

1. Purpose and Scope

1.1 This test method provides a laboratory procedure for:

1.1.1 Determining the effectiveness of chelating agents in disperse dyebaths for inactivating heavy metals that can cause shade change.

1.1.2 Evaluating the sensitivity of disperse dyes to metal-induced shade change during dyeing.

2. Principle

2.1 The effectiveness of chelating agents in sequestering metals in a dyebath, thereby preventing metal-induced shade change, is determined by the protocol in Fig 1.

2.2 Metal sensitivity of disperse dyes is determined by comparing control dyes and test dyes by the protocol shown in Fig. 2.
