Conventional sports textiles made from petroleum-based synthetic fibres are to be replaced in the future by sustainable, bio-based, cooling textiles. Polyethylene, previously used mainly in the packaging industry, is thus qualified for use in textiles and, as a bio-based drop-in solution, offers a cost-effective, sustainable alternative for the future.
TECNARO (Ilsfeld/Germany), BB Engineering (Remscheid/Germany), FALKE (Schmallenberg/Germany) and the Institut für Textiltechnik (ITA) of RWTH Aachen University have developed textiles from bio-based polyethylene (bioPE) in the bioPEtex project of the BIOTEXFUTURE Innovation Space.
TECNARO develops the bio-based PE compounds and handles their dyeing. ITA is concentrating on the process development for melt spinning (partially-oriented yarn, POY) and false-twist texturing (draw-textured yarn, DTY) of the bioPE yarns. BB Engineering implements the false-twist texturing on an industrial scale, and FALKE is developing the final T-shirt, which will be treated with a bio-based finish for improved elasticity.
The successful creation of a first T-shirt from the yarns developed in this project underscores their promising characteristics. This represents a key milestone and forms the basis for investigating potential market readiness in subsequent phases. Above all, the white BioPE T-shirt impresses with its pleasantly cool and soft touch. However, additional development, characterisation, and optimisation steps are necessary to make a market introduction possible.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
