Zero wastewater cotton dyeing system

Ralph Lauren

The water used for fabric dyeing alone is pollution about 20% of the world’s wastewater. Delivering the world’s first scalable zero wastewater cotton dyeing system, Ralph Lauren Corp., New York, NY/USA, has established Color on Demand, a multi-phased system.

Designed to help address water scarcity and pollution caused by cotton dyeing, Color on Demand is a new system composed of a set of technologies that will enable the recycling and reuse of all water from the dyeing process, establishing the world’s first scalable zero wastewater cotton dyeing system. In addition to significant water savings, this system reduces the amount of chemicals, dye, time and energy used in the cotton dyeing process. This will enable significantly shorter lead times for making product color decisions.
To implement this approach, Ralph Lauren brought together 4 leading innovators in their respective fields, including Dow Chemical Co. Midland, MI/USA, a leader in materials science; Jeanologia, Paterna/Spain, a leader in sustainable solutions for garment and fabric finishing, with high expertise in garment dyeing and close loop water treatment systems; Huntsman Textile Effects, Singapore, a global chemicals company specializing in textile dyes and chemicals; and Corob SpA, San Felice/Italy, a global technology leader in dispensing and mixing solutions, to reimagine each stage of the coloring process and join this shared mission to create a more sustainable and efficient system for cotton dyeing.
As part of the first phase of Color on Demand, Ralph Lauren optimized the use of Ecofast Pure Sustainable Textile Treatment, a pre-treatment solution developed by Dow for cotton textiles. When used with existing dyeing equipment, Ecofast Pure enables the use of up to 40% less water, 85% fewer chemicals, 90% less energy and a 60% reduction in carbon footprint compared to traditional cotton dyeing processes. Ralph Lauren is integrating this process into its supply chain and will launch product using this technology later this year.
