Acid red

Sunacid® dyes are water-soluble anionic dyes that are applied to fibers such as silk, wool, nylon and modified acrylic fibers using neutral to acid dye baths. Attachment to the fiber is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the fiber. Sunacid® dyes are not substantive to cellulosic fibers. Our Sunacid® Dyes such as Acid Black, Acid Red & Acid Yellow are free from all the prohibited Amines and Eco-Friendly. https://www.vipulorganics.com/acid-dye.htm
