Chemicals manufacturer Huntsman Textile Effects says mills that have adopted its all-in-one Eriopon E3-Save textile auxiliary for polyester processing have collectively saved more than 130m litres of water.

The technology, which launched a year ago, was born out of the growing demand for polyester fabric due to a growing consumer appetite for sportswear and athleisure. Huntsman says dyeing of the fabric and its blends is traditionally resource intensive, time consuming and costly.

Eriopon E3-Save textile auxiliary was engineered to address these challenges. It eliminates the need for separate pre-scouring, allowing pre-scouring, dyeing and reduction clearing to be combined in a single bath. Mills that use it dramatically shorten the polyester dyeing process and save water, energy and cost, Huntsman says.

"Our innovations aim to help mills improve their productivity and competitiveness while also contributing to the textile industry's shift to more sustainable practices and a reduced environmental footprint," says Kerim Oner, global marketing manager, Huntsman Textile Effects. "With Eriopon E3-Save, we have harnessed the unparalleled technical expertise and application know-how of our research and field teams to develop a product that is proven to reduce costs for mills and that meets current and anticipated industry sustainability standards."

Dae Young Textile Vietnam Co. was an early adopter of the Eriopon technology. Results from bulk production show it has reduced process time by over 20% and water consumption by over 50%, delivering annual cost savings of up to 30%.

The polymer technology of Eriopon E3-Save promotes controlled exhaustion to ensure right-first-time level dyeing. It extracts oil and oil-based impurities from the fibre during processing and displays a high affinity to disperse dyes, enabling the rapid removal of unfixed surface dyes from the fibre during reduction clearing. The technology also enhances reproducibility and improves wet- and rub-fastness.
