The first license for recycled yarns


With emerging climate change and environmental issues on the rise, the textile industry is now facing its own sustainability challenges. Only 1% of garments are recycled, while a staggering three quarters end up in landfill. However, the share of recycled fibers in short staple fibers has risen in recent years and is becoming increasingly important. Achieving high yarn quality with recycled fibers remains nevertheless a challenge.

Rieter expands Com4 brand: Introducing Com4recycling yarns

In response to the growing market demand for recycled yarns, Rieter extended the Com4 brand. Com4 is a globally registered trademark and stands for quality yarn that is spun exclusively on Rieter end spinning machines.

The following yarns containing recycled material can be licensed: Com4recycling-ring, Com4recycling-compact and Com4recycling-rotor. In 2023, our Turkish customer ORTA received the first Com4recycling-ring license – an achievement that was celebrated at ITMA Milan. 

To apply for a license, spinning mills must produce their recycled yarn on a Rieter card, draw frame and end-spinning machine. In addition, a Global Recycled Standard (GRS) certification is required.
