Huntsman said in a press release, “The diffusion accelerant is low-odor, free of benzyl benzoate, and other hazardous substances. Part of Huntsman’s range of innovative dyEvolution dyeing auxiliaries, it uses Huntsman’s active diffusion technology to enable high-speed dyeing with best-in-class leveling, retarding, and migration properties.”
Kerim Oner, global marketing manager for dyeing auxiliaries at Huntsman Textile Effects said about the product, “UNIVADINE E3-3D diffusion accelerant delivers across three key dimensions, diffusion, leveling, and migration, for exceptional performance and environmental and economic sustainability.”
“Its environmental credentials offer mills greater processing flexibility and an optimum price-performance ratio and we expect this latest offering to change the way that the industry dyes polyester and blends while meeting stringent environmental standards,” he added.
According to the press release, UNIVADINE E3-3D diffusion accelerant 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. Finally, as the dye bath heats up, the product’s strong support for disperse dye migration ensures the dye molecules are evenly absorbed.
As a result of this cutting-edge diffusion technology, UNIVADINE E3-3D diffusion accelerant can be used to successfully dye polyester fibers in tightly wound or high-density yarn/beam dyeing and is suitable for jet applications without the need for anti-foaming products.
Polyester, microfibers, and blends treated with UNIVADINE E3-3D diffusion accelerant comply with the requirements of bluesign®, in addition to being suitable for Standard 100 by Oeko-Tex and an approved input dyeing auxiliary chemical for GOTS (Global Organic Textile Standard) certified textile products, according to the company.
