Nylon staining inhibitor for dyeing of nylon/cellulose blends
Neoleve NYC-D (direct dyes, neutral fixation type reactive dyes) and NYC-R (reactive dyes)
For dyeing method (1), adding Glauber's salt in portion is vital.
With dyeing method (1), Neoleve NYC-D can effectively inhibit staining on nylon. In one-bath acid/direct dyeing of nylon/cotton blends, the use of an anti-nylon staining agent is necessary as more nylon staining due to direct dyes is caused in acid.
The effects of anti-nylon staining agents are superior in the acid side, however, the use of an excessive amount may result in considerable acid dye staining on cotton. The addition of Glauber's salt in portion is effective for level dyeing of the cellulose side using direct dyestuff.
