Worldfast NDF 2070 marketed by us, is a textile auxiliary used in the dyeing and printing industries to increase the colorfastness of dyed in cloth. It can generate insoluble colored substances with dye on the cloth, so improving the color of washing, sweat fastness, and occasionally sun fastness. Our Worldfast NDF 2070 is very effective and safe to use. When compared to traditional Formaldehyde-based dye fixing agents, it delivers far superior results in terms of tone/color shift and dye leakage.
Worldfast NDF 2070 is an excellent non formaldehyde dye fixing agent to the wash fastness of Reactive and Direct dyes
