Archroma is introducing two new metal and halogen-free* acid dyes, Navy S-3R and Black S-3N to its Nylosan S range. Especially developed for nylons and blends, these dyes meet long-standing market demands. As per an Innovation in Textiles report, the Nylosan S range offers alternatives to dyes generally used for nylon dyeing and contains metals. Both the new dyes offer a halogen-free option to traditional dyes.

The full Nylosan S range offers a wide range of colors, with the new dyes targeting the color matching and fastness specifications of the blacks and navies of major sportswear brands. These navy and black dyes display the same color constancy as the dyes used in many leading color standards. Both of them have high fastness and buildup, and a wide shading gamut for industry-leading metal-free acid dyes. They are REACH registered and bluesign approved.
