Huntsman, a leading global provider of high-quality dyes and chemical, introduces Univadine E3-3D diffusion accelerant, specifically developed for high temperature dyeing polyester, microfibers and blends.
The Univadine E3 -3D accelerant is designed to enhance three-key dimension in the processing- Diffusion, On-tone leveling/retarding and Migration. It is low-odour and free of benzyl benzoate and other hazardous substances. It is incorporated with Huntsman’s Active Diffusion Technology, which enables high speed dyeing with best-in-class leveling, retarding, and migration properties.
The accelerant high affinity to polyester, swells up the fibre and therefore, increases the diffusion of the disperse dye, even at low temperature. The multiple leveling mechanism further reduces the exhaustion time ensuring the safe and defect-free dyeing. Finally, as the dye bath heats up, the strong support for disperse dye migration ensures the dye molecules are evenly absorbed.
This diffusion technology helps in the successful dyeing polyester fibres in tightly wound or high-density yarn/beam dyeing and is also suitable for jet applications without the need for anti-foaming products. Also, its active diffusion technology, further helps with the reduced exposure to high heat and minimize the potential to damage the elastane in polyester elastane blends which gives one tone dyeing of microfiber. The migration support of Univadine E3-3D diffusion accelerator is also said to increase reproducibility, allowing mills to dispense with additional leveling agents.
“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,” said Kerim Oner, Global Marketing Manager for Dyeing Auxiliaries at Huntsman Textile Effects.
The fabric treated with this diffusion accelerator fulfills the requirement of bluesign, and is also suitable for Standard 100 by Oeko-Tex and an approved input dyeing auxiliary chemical for GOTS (Global Organic Textile Standard) certified textile products.
