Preparation and Application of the Soda Substitute for Medium Temperature Reactive Dyestuffs

Abstract:

Inorganic alkalis and pH stabilizers are employed to building a soda substitute MZ-M for dye fixing of medium temperature reactive dyestuffs. The influences of alkalis, buffers, alkalinity controller, additives and the ratio between them on its dye fixing properties are studied. Furthermore, the practicability of MZ-M for dye fixing of medium temperature reactive dyestuffs is appraised. The studies show that the dye depth K/S of samples treated with MZ-M is not less than the samples dye fixed with sodium carbonate, the color fastnesses are more than grade 4 and the dosage of MZ-M is only 8-10% of that of Na₂CO₃.
