Description

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.
