Acid Blue 260 is mainly used for the dyeing and printing of wool, nylon and silk, and also for the coloring of leather. It can be used as a special dye for nylon, suitable for dyeing dark colors on nylon.
Acid Blue 260 is highly effective on protein fibers such as wool and silk, and also provides consistent results on polyamide fibers like nylon.
For optimal dyeing, maintain acidic pH conditions (typically pH 4–5), use controlled temperature rise, and add appropriate electrolytes to ensure even levelling and vivid color development.
Yes, Acid Blue 260 blends well with other acid dyes, allowing for customized shades without compromising fastness or uniformity.
It exhibits good wet-fastness and moderate light-fastness, with variations depending on the fiber type and depth of shade applied.
Store in a cool, dry place, away from strong oxidizing agents. Keep containers tightly closed to maintain stability and prevent caking.
