Devan/Jeanologia: less water for antimicrobial and skincare finishes
To further reduce water consumption during the application of the Bi-Ome antimicrobial and R-Vital skincare range, the supplier of specialty chemicals Devan Chemicals NV, Ronse/Belgium, has been working together with the supplier of sustainable technologies for garment finishing, Jeanologia, Paterna/Spain.
With increased attention to climate change and limiting excess water consumption in textile production (whether denim or other textiles), the companies worked together to evaluate the application of Devan finishes onto garments using the patented e-Flow technology.
e-Flow technology can accomplish a considerable number of finishing effects with the highest quality, a minimal amount of water and zero discharge. The technology uses micronization and nebulization to substitute traditional abrasion process and deliver performance chemistry using nano-bubbles instead of water. It reduces the cost of application, saves the amount of water used and ensures that the correct amount of chemistry stays in the garment and not in the water. e-Flow is suitable for every industrial washing machine. This allows the application of Devan’s technologies in a more sustainable way than using traditional application equipment, even for smaller production runs and direct onto garments.
Ralph Lauren: zero wastewater cotton dyeing system
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.
Archroma: new water-saving dyeing process for denim with Jeanologia
The launch of ‘Pad-Ox G2 Cold’, a water-saving dyeing process at room temperature for casual looks, has been announced by the producer of dyes and specialty chemicals Archroma Management LLC, Reinach/Switzerland, and the supplier of sustainable technologies for garment finishing, Jeanologia, Paterna/Spain
Archroma initially introduced its eco-advanced Pad-Ox dyeing process for woven fabrics. By combining the oxidation and fixation steps, it is possible to shorten the dyeing process and thus realize substantial resource savings in water, wastewater, cotton waste, and energy.
Meanwhile, Jeanologia has been working on the technology side, with laser and eco-finishing solutions. Its G2 Dynamic was the first ozone treatment for continuous fabric that reduces the amount of water and chemicals used, thus saving costs further down the textile chain. This technology makes fabric more stable and consistent and prepares the fabric better for the use of other technologies like laser.
In their joint project, the 2 companies have come up with a way to apply the Pad-Ox dyeing process at room temperature, whilst still improving fastnesses and allowing higher contrasts after washdown. The new Pad-Ox G2 Cold dyeing process works thanks to the insertion of very small machinery into the existing finishing range process, using cold processing and thus operating with much less water, carbon footprint and energy than traditional finishing processes, whilst retaining the water and other resource savings offered by the Pad-Ox technology.
