• Reduction prevention for reactive dyes
• Prevention of facing in discharge printing
• Alkaline boiling assistant for vat dyed or printed materials
• Prevention of fixation of vat dyes in overprinting

 

Procedures

For reactive dyes, greenish-yellows and anthraquinone based blues are particularly susceptible to reduction. Inclusion of 1% Orcotol MN Powder™ in all formulas will prevent reduction.

0.5 – 1.5 oz/gal of Orcotol MN Powder™ assists in alkaline or kier boiling of vat dyed or printed materials before bleaching. Its use prevents reduction, stripping and/or marking off. It is not used in pressure kier boiling of colored materials.

Orcotol MN Powder™ prevents fixing of vat colors when they are over printed. This use needs a high concentration of 10 – 20% in the printing paste.

Orcotol MN Powder™ prevents doctor blade streaks and/or facing in discharge printing of colored goods. In this use, the depth of the ground color is maintained when there is carry-over of the discharge agent. A solution containing 0.5 – 1.5 oz/gal may be padded onto material to be discharged. Alternately, a 1.5 – 2.5 oz/gal solution may be applied on the print machine.
