Huntsman accelerates polyester dyeing

Huntsman Textile Effects has introduced UNIVADINE® E3-3D diffusion accelerant to help mills achieve high-performance dyeing of polyester, microfibers and blends in a way that complies with current and anticipated industry sustainability standards. UNIVADINE E3-3D diffusion accelerant is low-odor and free of benzyl benzoate and other hazardous substances. It uses Huntsman’s Active Diffusion Technology to enable high-speed dyeing with best-in-class leveling, retarding and migration properties. It has a high affinity to polyester, causing the fiber to swell and increasing the diffusion of the disperse dye, even at lower temperatures. Multiple leveling mechanisms then slow down the exhaustion rate to ensure safe, defect-free dyeing.
