At the conference held over three separate afternoons on September 30, October 1 and October 7, delegates learned that Sweden will be introducing Extended Producer Responsibility (EPR) for waste textiles and clothing in early 2022, before the adoption of a similar European Union. – global EPR system in 2025.
In Sweden, this is already leading to the establishment of advanced digital sorting and recycling infrastructures and, from a brand perspective, H&M is now a leader in the field both in addressing the circularity of its suppliers and minimizing its own waste. Swedish companies are also active in the development of new fibers derived from garment waste, building on the country’s historic leadership in pulp and paper production.
Members of the Textile Machinery Association of Sweden (TMAS) play a key role in the development of new sustainable processes for dyeing, finishing and decorating textiles. TMAS members Baldwin Technology and Coloreel both showcased solutions for sustainable finishing and decorating at the recent Sustainable Textile Finishing Conference.
At the Sustainable Textile Finishing Conference, however, it was said that any environmental gains made by these new sustainable fibers can potentially be negated in the further processing to which they are subjected – and particularly in dyeing, finishing. and conventional, resource-intensive decoration. TMAS said in a press release. Both Baldwin Technology and Coloreel have developed solutions to address this problem.
Baldwin’s vice president of global business development Rick Stanford told the conference that his company’s TexCoat G4 non-contact spray technology dramatically reduces water, chemical and energy use in the process. finishing. It sprays chemistry consistently and evenly onto a fabric surface and applies it only where needed, on one or both sides.
“Customers can expect no contamination of the bath during the finishing process, as well as minimal downtime during changeovers, which are facilitated by recipe management which includes automated chemistry and selection. coverage, ”he said.
TexCoat G4 also doesn’t waste chemistry during color, fabric or chemistry changes, and since only the required volume of chemistry is applied to the fabric, wet pickup levels can be reduced by up to 50 percent. , which leads to 50 percent less water and energy consumption compared to conventional finishing processes. In addition, several customers combine TexCoat Spray and rear coating as standard before the train. This simplifies the production process from two stages to one, providing both drying savings and increases in productivity.
Coloreel CEO Mattias Nordin described the advantages of his company’s technology which allows instant, high-quality coloring of a textile yarn on demand and can be paired with any existing embroidery machine without modification. . This makes it possible for the first time to achieve unique effects such as shades and gradients in an embroidery.
“Our technology is now commercialized and we are expanding our business globally,” said Nordin. “The foundation of the company was based on the idea that there were millions of varieties of spools of yarn, many of which would become obsolete and waste and that it would be easier to dye the yarn as you go. as you use it. This is what we have achieved.
Based on a CMYK ink system, Coloreel’s advanced rapid coloring software and high speed drive technology allow a single needle to perform what previously required several – and with much more consistent dot quality .
Additionally, existing yarn dyeing factories can add a single solid color to a yarn, but by instantly dyeing a white base yarn during production, Coloreel allows complete freedom to create unique embroideries without any limitation in use. colours. Color changes along the wire can either be made quickly from one solid color to another or gradually, to achieve smooth transitions or any desired coloring effect.
This offers great advantages in terms of durability. There is a significant reduction in wasted inks, while water consumption is minimized and production speeds are increased. The technology allows for reduced installation and delivery times as well as significant flexibility in production quantities, while eliminating the need for large inventories of yarns.
“It’s great to see TMAS members playing a pioneering role in what now promises to be a vital overhaul of the textile supply chain here in Scandinavia,” added General Secretary TMAS Thérèse Premler-Andersson. “All of these ideas are now gaining momentum and are likely to be adopted around the world. The result will be a more circular and sustainable industry, for the benefit of all. “
