Recover, Rieter and Polopiqué are partnering to produce high quality and fine ring spun cotton yarns with a higher percentage of mechanically recycled fibres than has previously been possible.

The companies have already produced a high-quality Ne 30 compact yarn that contains an impressive 40% of recycled post-industrial fabric waste. Typically, a recycled fibre content of only 20% is used when producing recycled ring yarn.

The ring spinning process used for this project incorporates a Rieter comber and COMPACTdrum compacting device. Recover’s recycled cotton fibres were blended with virgin cotton at a 50/50 ratio with undesirable short fibres and neps effectively removed during combing, resulting in a significant enhancement in yarn quality and improved running performance of the ring spinning machine. Furthermore, the fibres removed by the comber are perfectly suitable for processing on Rieter rotor spinning machines. With these advantages in place, the process aims to be GRS Global Recycling Standard certified.

“We’re proud to team up with Recover and Polopiqué in a breakthrough effort that will pave the way toward a more sustainable future,” said Franziska Häfeli, Rieter’s head sales and marketing. “Our expertise in spinning recycled fibres will help achieve our shared goals and together we will make recycling mainstream.”

“By increasing the percentage of the recycled content in the yarn and final product, we can scale the adoption of sustainable fibres like Recover and make a lasting positive impact,” added Alfredo Ferre, CEO of Spain-based Recover

For Eduardo Guimarães, weaving director at Portugal-based Polopiqué, the aim is to continuously test, develop and create new products through the use of cutting-edge technology and raw materials.

“Coming together and sharing knowledge and know how has allowed us to reach our collective product objective, and we are excited about the impact that this will have on our industry,” he said.
