Chemicals manufacturer Huntsman Textile Effects has developed what it says is a new eco-friendly dyeing auxiliary that cuts the time and cost of dyeing polyester.

The new Eriopon E3-Save reduces time, water and energy by enabling pre-scouring, dyeing and reduction clearing in a single-bath.

Its introduction comes as demand for polyester and man-made fibres is booming as sports and athleisure apparel markets expand rapidly around the world, yet at the same time, brands, consumers and mills are increasingly focused on sustainability and performance.

In contrast, the traditional polyester dyeing process is costly, time consuming and resource intensive. 

"Eriopon E3-Save dyeing auxiliary delivers in all critical stages of polyester dyeing from pre-scouring to washing-off for exceptional performance and environmental and economic sustainability," says Oliver Gerlach, global marketing manager for process chemicals at Huntsman Textile Effects. "Its environmental credentials offer mills greater processing flexibility and an optimum price-performance ratio." 

Utilising polymer technology, the new auxiliary can be used to dye in jet applications without the need for anti-foaming products, and also allows mills to dispense with additional levelling agents.

The company adds that polyester, microfibres and blends treated with Eriopon E3-Save auxiliary comply with the requirements of Bluesign, Level 3 of the Zero Discharge of Hazardous Chemicals Gateway (ZDHC) and the Restricted Substances Lists of international brands, in addition to being suitable for processing of textiles in compliance with Standard 100 by Oeko-Tex and the Global Organic Textile Standard (GOTS).

The product is the latest addition to Huntsman's dyEvolution range.
