Dow ECOFAST™ Pure: Sustainable Cotton Pretreatment

Dow is a global leader in textile auxiliary chemicals and related technical solutions. They are committed to delivering innovative and sustainable high-performance products, one of which is ECOFAST™ Pure. In short, the sustainable textile treatment enables cotton to have a higher affinity for dyes which is beneficial from a resource consumption and wastewater generation standpoint.  

Problem

The global fashion has a significant impact on our world – our culture, economy and planet. While this leading industry provides the population with colourful apparel, textile dyeing is the second largest cause of water pollution in the world. It consumes 5 trillion litres of water each year, which is nearly enough to supply all humanity with drinking water. 

Cotton in particular, requires more water than other textiles for dyeing with about 200 litres to produce 1kg of fabric. Typically, the greatest water consumption occurs during the post-washing rinse phase, which is necessary to remove dye that didn’t fix to the fibre.

Solution

ECOFAST™ Pure is an award-winning patented cationic treatment developed for the cotton dyeing process. It is suitable for knitted and woven fabric, denim and garments. It meets the ZDHC Roadmap to Zero Programme and Manufacturing Restricted Substances List (MRSL), to help brands achieve their sustainability targets and address important challenges like water pollution and water scarcity.

It is compatible with popular direct and reactive dyes and delivers comparable or enhanced colorfastness. ECOFAST™ is applied before the dyeing process; the pre-treated cotton subsequently acquires a permanent positive charge, which enables the cotton to have a higher affinity for negatively charged molecules such as dyes.

Outcome

90% less process chemicals including dyes, salt and other additives

50% less water with fewer rinses and faster cycle times 

50% less dye with improved uptake

40% less energy with room-temperature dyeing
