Case Study

Acid Dye Composition and Dyeing Method Using Same

WO2014061568A1, 2013.

Generally speaking, when dyeing polyamide fibers with yellow, red, and blue primary color dyes, leveling acid dyes are used for dyeing, which have excellent dye migration and hiding properties, but poor wet fastness. In order to solve these problems, a uniform and reproducible high-performance acid dye composition and a dyeing method using the composition have been proposed.
Acid Dye Composition
· Combining specific red acid dyes, mixtures of red acid dyes, specific yellow acid dyes and/or specific blue acid dyes. By combining them, a dye composition was discovered that not only had strong fastness for each color, but also had well-balanced fastness among the three primary colors and uniform dyeing properties when dyeing.
· In the blue acid dye mixture (C), the blue acid dye represented by formula (4) is 30 to 70 wt%, the blue acid dye represented by formula (5) is 10 to 50 wt%, and formula 6) (C.I. I. acid blue 138). Acid blue 138 is 20 to 60 wt%.
Dyeing Method
· The fiber is immersed in an aqueous medium of acid dye composition and at a temperature of about 110 to 1.1 atm. Treat at -100°C for 30 minutes to 1 hour. Then, it is washed with water, dried with hot water if necessary, and dried to obtain a dyed product.
