RECYCLING MIXED-FIBRE GARMENTS BECOMES A REALITY: RADICIGROUP, THE LYCRA COMPANY AND TRIUMPH TAKE CIRCULAR FASHION A STEP FORWARD
The process, which is both economically and environmentally sustainable, has enabled the production of an underwear set made from 100% recycled nylon and LYCRA® fiber in a closed-loop system.

Recycling of garments made from different types of fibers has always represented a major challenge for the textile industry. In the absence of a chemical or mechanical process capable of separating and recovering the individual materials, these garments have so far become waste destined for incineration or landfill.
Today, however, Radici InNova, the RadiciGroup division dedicated to research and innovation, has developed an innovative recycling process based on selective dissolution technology, capable of treating mixed textile waste — such as swimwear, tights and leggings — and recovering both nylon and LYCRA® fiber, making them available again for the production of new garments.
The collaboration with The LYCRA Company and Triumph, internationally-renowned lingerie brand, has made it possible to validate the process by using the recovered fibers to create a 100% recycled lingerie set.
The process, internationally patented, uses non-toxic, non-flammable and environmentally compatible solvents. It can be applied to the main types of nylon (PA6 and PA66) and is economically sustainable because it allows for the recovery of both nylon and LYCRA® fiber, regardless of their respective proportions in the fabric, as well as the solvent itself.
"Thanks to this project, textile recycling enters a new dimension, demonstrating for the first time that it is possible to recover fibers from mixed fabrics and reuse them to produce new garments. This is an unprecedented innovation that opens up revolutionary development opportunities for the textile industry. As RadiciGroup, we are proud to have conceived and achieved this important milestone together with our partners, and we are ready to take the next steps."

"This innovative project highlights the role that elastane can have in helping to advance circularity in the apparel industry. Working closely with Radici InNova and Triumph, The LYCRA Company has demonstrated that LYCRA® fibers can retain their renowned stretch and recovery performance — providing comfort, fit and ease of movement — even when reintegrated into the spinning cycle."

The project began four years ago, when Radici InNova launched the study of an innovative process for the dissolution and separation of mixed textile fibers. After the initial development phase, subsequent tests made it possible to recover samples of LYCRA® fiber from multi-material fabrics, which were then sent to The LYCRA Company to verify their recyclability.
The next step was to demonstrate the feasibility in practice: Triumph provided its own production surplus, a fabric containing 16% LYCRA® fiber. From this material, Radici InNova succeeded in recovering both LYCRA® fiber and nylon. The LYCRA® fiber was then re-spun by The LYCRA Company, while RadiciGroup processed the recycled nylon to produce new Renycle® yarn.
Using these recycled yarns (LYCRA® fiber and Renycle®), a 60-meter black fabric was created, which Triumph used to produce a coordinated lingerie set — bra and briefs — concretely demonstrating the possibility of closing the loop: from textile waste to new garments.
The result achieved so far by Radici InNova, The LYCRA Company and Triumph should be considered a prototype (concept garment) designed to prove the technical feasibility of recycling mixed textiles and lay the groundwork for its future industrialization.
"Although still in its early stages, Triumph is proud to contribute to this pioneering initiative and to explore the potential of this innovative recycling technology for future applications. Our next step will focus on developing a capsule collection, while also working on solutions to ensure product identification, traceability and circularity systems, so that garments can remain in use for as long as possible and, once they reach the end of their life, can be recycled in the most appropriate way. At Triumph, we are committed to promoting innovation and collaboration in the field of sustainability. Being part of this project strengthens our belief that circularity for garments made from mixed textile fibers is possible, and we are proud to help turn this vision into reality."
