Solution to maintain fibre length in mechanical recycling

20/08/2025
Textile Fiber Boost, a spin-off from Saxion University in the Netherlands, has successfully finalised initial testing of a technology that promises to preserve fibre length in mechanical recycling processes. This would enable the production of higher-quality recycled yarns. The tests were conducted on post-consumer polycotton waste (65% polyester / 35% cotton) and denim (100% cotton). 

The pre-treatment process is said to “optimise” fibres before mechanical recycling, “reducing damage during tearing and boosting both fibre yield and strength”. 

Along with nine companies and research institutes, Textile Fiber Boost is part of TEXPOWER, a Dutch government-funded research consortium. An acronym for Textile Polycotton Waste Evaluation and Recycling, TEXPOWER members include CELLiCON, a company developing a separation technology for polycotton blended textiles. Frankenhuis, Saxion University of Applied Sciences, SaXcell and Spinning Jenny are also involved in the project that has been awarded a €9 million budget over a five-year period. 

Textile Fiber Boost has also secured a loan from the Dutch research council (Nederlandse Organisatie voor Wetenschappelijk Onderzoek, or NWO) to further investigate the application of its pre-treatment technology on cotton.
