1. Purpose and Scope
1.1 This test method provides a laboratory procedure for:
- Determining the effectiveness of chelating agents in disperse dyebaths for inactivating heavy metals which can cause shade change.
- 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 a shown protocol.
