Dianix XF2

The next generation of high wet fastness disperse dyes.bluesign_approved

Polyester is the most important textile fiber and consumption has continuously grown over the years. Polyester can only be dyed with disperse dyes and is used in a wide range of industry segments. The demands in fastness specifications for high wet fast sportswear, apparel and workwear from Retailers & Brands on critical fabrics like polyester microfiber, polyester/elastane, polyester/cellulosic and other polyester blends are challenging the textile industry. In addition the tightened environmental standards (Restricted Substance Lists – RSL’s) set by Retailers & Brands must be taken into consideration.

As the leading manufacturer of dyes and auxiliaries, DyStar responds to these requirements by continuously researching for new products. Over the years, the existing Dianix XF and Dianix SF range was extended with new high performance products and also completely new chemistry was used for development of the Dianix CW-SF dyes.  The latest development is the Dianix XF2 range, the next generation of high wet fastness dyes.
