Acid fixing agent MR-847
Acid fixing agent MR-847
Acid fixing agent MR-847 is anionic polymer, Which is suitable for color-fixing after dyeing with acid dyes for nylon, wool, silk fabric and so on, The fixer can improve the color fastness each item and prevent the dyeing stain on nylon from being dyed by reactive dye. When dyeing cotton brocade blend fabric,
Features and advantages:
1. The effect of color fixation is excellent, Which can obviously improve the washing color fastness and wet fastness for dyed fabrics or yarns and with water stains, sweat stains, sea water color fastness and so on.
2. Strong dispersion, Never produce solid spots when application.
3. With anti-dyeing effect on nylon-cotton blend with reactive dye and reduce stain on nylon fabric with reactive dyes.
