SINGAPORE – Textile dyes and auxiliaries business, Huntsman Textile Effects, has unveiled a new diffusion accelerant which, it claims, could change the way that the textile industry dyes polyester and blends while meeting stringent environmental standards. Univadine E3-3D is a next generation accelerant launched to help mills achieve the high-performance dyeing of polyester, microfibres, and blends in an environment-friendly way that complies with industry sustainability standards. Huntsman is a provider of high quality dyes, chemicals, and digital inks for the textile industry.

The diffusion accelerant is low-odour and free of benzyl benzoate and other hazardous substances. Part of Huntsman’s range of dyEvolution dyeing auxiliaries, it uses Huntsman’s active diffusion technology to enable high-speed dyeing with best-in-class levelling, retarding, and migration properties.

Said Kerim Oner, global marketing manager with Huntsman Textile Effects: “Univadine E3-3D diffusion accelerant delivers across three key dimensions, diffusion, levelling, and migration, for exceptional performance and environmental and economic sustainability. Its environmental credentials offer mills greater processing flexibility and an optimum price-performance ratio. We expect this latest offering to change the way that the industry dyes polyester and blends while meeting stringent environmental standards.”

The new accelerant is said to have a high affinity to polyester, causing the fibre to swell and increasing the diffusion of the disperse dye, even at lower temperatures. Multiple levelling 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.

Univadine can be used to successfully dye polyester fibres in tightly wound or high-density yarn/beam dyeing and is suitable for jet applications without the need for anti-foaming products.
