Singapore-based Huntsman Textile Effects has introduced Eriofast® Navy M reactive dye for achieving navy and royal blue shades with good wetfastness on polyamide and polyamide/elastane blends including microfibers.
According to the company, the dye — which is suitable for premium sportswear, swimwear and lingerie applications — may be used as a self-shade or in combination with Eriofast Blue 3R or Eriofast Black M to provide intense royal blue, deep dull navy and bluish-black navy shades. Huntsman reports the dye process is short and simple; and that the dye used in combination with Eriofast FX exhausts smoothly and uniformly, providing fast, level and reproducible color. Other reported benefits include good color continuity under different light sources, durability, and the ability to achieve unique color blocking effects for blue and white or color-contrast styles.
Huntsman also reports that because the dye does not require hydrophobic fixing agents to improve fastness, the fabrics have a naturally soft, comfortable, moisture-absorbing hand.
Eriofast Navy M dye is certified to OEKO-TEX®, bluesign®, Responsible Care® and European Union textile standards; and complies with the Restricted Substances List requirements. It also has been registered as a novel dye under the United Kingdom’s Society of Dyers and Colourists Colour Index System and has been nominated for a SDC Innovation Award.
