Sustainable athletic wear made from bio-based Polyethylene

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.

Small tolerances, big impact and a recyclable alternative to elastane

ITA Master's student Janne Warnecke investigated tension differences over the fabric width in the weaving process and thereby contributed to quality assurance; ITA Bachelor's student Jasmin Roos found a basis for the development of recyclable yarns and textiles. For these developments, they were awarded the Walter Reiners Foundation's Promotion and Sustainability Prizes on 27 November. Peter D. Dornier, Chairman of the Walter Reiners Foundation, presented the awards at the Aachen-Dresden-Denkendorf International Textile Conference (ADD-ITC) in Aachen, Germany.

Aachen Summer School: Strengthening German-Korean cooperation in 4D and robotics

The Aachen Summer School has established itself as an important platform for promoting cooperation between RWTH Aachen University and Seoul National University. The focus is on practice-oriented research projects in the field of 4D and robotics technologies, which have been successfully implemented for years at the Institut für Textiltechnik of RWTH Aachen University.

Innovation center for textile circular economy inaugurated

Just over eight months after the foundation stone was laid, the new Innovation Center for Textile Circular Economy was officially inaugurated today at TITK Rudolstadt. Thuringia's Minister President Mario Voigt, TITK Director Benjamin Redlingshöfer, and other guests of honor cut the ribbon to the modern building complex and viewed the premises, which are now ready for occupancy. The “DICE – Demonstration and Innovation Center for Textile Circular Economy” is TITK's largest single investment to date. The Free State of Thuringia supported the total cost of €11.5 million with €8 million in GRW and FTI funding.

Sustainable design of Geosynthetics and roof underlayments made from recyclates

Is it possible to recover plastic recyclates from previously unused waste streams in order to produce high-quality fibers and films? How can bio-based polymer fibers be manufactured so as to allow adjustable biodegradability? These are the questions being addressed by researchers from the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE in the Zirk-Tex project.

More safety and comfort for protective clothing thanks to auxetic fabrics

When everyday materials are pulled, they stretch or elongate in the direction of the pull and become narrower in cross-section. We can also observe this property in two-dimensional textiles. Auxetic structures behave differently here. They have the striking property of not changing under tensile stress or even increasing their width or thickness. These properties are advantageous, for example, in protective textiles or textile filter media. The DITF are researching auxetic fabrics for various applications.

Fraunhofer CCPE presents the “Monomaterial Design Set” – Innovative solutions for circular product design

Composite materials made from different types of plastic often extend the lifetime of products but make recycling more difficult in the circular economy. That is why Fraunhofer CCPE has developed the “Monomaterial Design Set”. This new approach helps to reduce the variety of plastics used in durable products and offers circular solutions for designers and product developers.

B.I.G. Yarns achieves EcoVadis Platinum Rating, ranking among top 1% of companies worldwide

B.I.G. Yarns, the carpet yarn brand of B.I.G. and a leading manufacturer of polyamide (PA), polypropylene (PP) and polyester (PET) yarns for contract, automotive, and high-end residential applications, has been awarded the EcoVadis Platinum Medal, placing the company among the top 1% of more than 130.000 companies assessed globally.

Mimaki upgrades TS330 series for vibrant and seamless dye sublimation printing

The TS330 Series now provides users with an extended colour gamut, offering the flexibility to serve different markets profitably from one solution – from fashion to décor to signage – with improved colour vibrancy, fidelity and accuracy. Mimaki also introduces a larger solution to the TS330 Series, the TS330-1800, able to accommodate single-piece, wide textile fabrics, ideal for larger home décor applications.

Storm Creek achieves bluesign® PRODUCT status

Storm Creek (ASI#/PPAI#) is proud to announce a meaningful sustainability milestone: the company has achieved bluesign® PRODUCT status: becoming the first US-based supplier in the promotional products industry to earn this globally respected certification. While this marks an industry first, for Storm Creek, it represents something far more important: a continuation of doing what they believe is right.
