According to the company, 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.
The manufacturer explains, as a result of this diffusion technology, Univadine E3-3D diffusion accelerant 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.
Reducing exposure to high heat, its Active Diffusion Technology minimises the potential to damage the elastane in polyester-elastane blends and provides for on-tone dyeing of microfibers. The migration support of Univadine E3-3D diffusion accelerant is also said to expand reproducibility, allowing mills to allocate with additional leveling agents.
Kerim Oner, Global Marketing Manager for Dyeing Auxiliaries at Huntsman Textile Effects said that, â€œUnivadine E3-3D diffusion accelerant delivers across three key dimensions â€“ diffusion, leveling and migration â€“ for exceptional performance and environmental and economic sustainability. Its environmental credentials offer mills greater processing flexibility and an optimum price-performance ratio.â€ Also, â€œWe expect this latest offering to change the way that the industry dyes polyester and blends while meeting stringent environmental standards.â€
Univadine E3-3D diffusion accelerant has a high affinity to polyester, causing the fibre 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 productâ€™s strong support for disperse dye migration ensures the dye molecules are evenly absorbed.
Huntsman Textile Effects introduces Univadine E3-3D diffusion accelerant to help mills achieve high-performance dyeing of polyester, microfibers and blends in an environment-friendly way that complies with current and anticipated industry sustainability standards.
The company reports that the demand for polyester and man-made fibres is flourishing as sports and athleisure apparel markets expand swiftly around the world. At the same time, big-name brands that set trends in the sector continue to increase focus on sustainability and performance. As such, this is putting force on mills since the current industry standard involves chemically active diffusion accelerants that contain unwanted chemicals and require additional leveling agents and anti-foaming products that may be hazardous to people and the environment.
Univadine E3-3D diffusion accelerant is low-odour, free of benzyl benzoate and other hazardous substances, developed by Huntsman Textile Effects specifically to meet these challenges. Part of Huntsmanâ€™s range of dyEvolutiondyeing auxiliaries, it uses Huntsmanâ€™s Active Diffusion Technology to enable high-speed dyeing with best-in-class leveling, retarding and migration properties.
