ACIDIC DYE COMPOSITION, APPLICATION OF ACIDIC DYE COMPOSITION, AND DYEING METHOD OF NYLON FIBER USING ACIDIC DYE COMPOSITION

摘要

To provide an acidic dye composition capable of largely reducing dye waste liquid.SOLUTION: There is provided an acidic dye composition for dyeing a nylon fiber, containing an acidic dye and a water-soluble Cacompound, and having content of the water-soluble Cacompound in a range of 0.1 pts.wt. to 50 pts.wt. based on 100 pts.wt. of total amount of the acidic dye. The water-soluble Cacompound is CaCl, Ca(CHO), CaSO, or the like and can be used for a nylon microfiber substrate or the like.SELECTED DRAWING: None
