1. Purpose and Scope1.1 This test method provides a laboratory procedure for:
2.2 Metal sensitivity of disperse dyes is determined by comparing control dyes and test dyes by a shown protocol.
- 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.
