1.Purpose and Scope
1.1This test method provides a laboratory procedure for:1.1.1Determining the effectiveness of chelating agents in disperse dyebaths for inactivating heavy metals which can cause shade change.1.1.2Evaluating the sensitivity of disperse dyes to metal induced shade change during dyeing.
2.Principle
2.1The effectiveness of chelating agents in sequestering metals in a dyebath, thereby preventing metal-induced shade change, is determined by the protocol in Fig. 1.2.2Metal sensitivity of disperse dyes is determined by comparing control dyes and test dyes by a shown protocol.
