New series of DIN standards enables comparability of spacer fabrics

Until now, spacer fabrics have not been tested according to separate test procedures. This meant that important characteristics were not taken into account in the tests.

The first national test standard for spacer fabrics has now been developed under the direction of the Institut für Textiltechnik of RWTH Aachen University, short ITA, in the joint project NormATex (Standardization for Spacer Fabrics), which is publicly funded by the Federal Ministry for Economic Affairs and Energy, short BMWi, within the WIPANO guideline.

Spacer fabrics are textile structures consisting of two textile cover surfaces and at least one spacer thread system. The cover surfaces are kept apart at a certain distance by the spacer thread. This structure gives spacer fabrics special properties that make them a substitute material for other, non-textile materials. As a result of their special properties, spacer fabrics differ from conventional, flat fabrics.

Up to now, spacer fabrics have been tested according to standards for flat fabrics or other, non-textile materials. However, these standards do not take into account the special requirements for testing spacer fabrics. Therefore, objective comparisons between spacer fabrics and each other or with conventional flat fabrics or non-textile materials cannot be made in all areas of application.

In the documents of this series of standards the special properties of spacer fabrics are given special consideration. This ensures the standardized testing of these properties and thus objective comparisons between

1. spacer textiles among themselves,

2. spacer fabrics and flat 2D-textiles and

3. spacer fabrics and non-textile materials

will be enabled.

The developed standardization document DIN 60022-1, Spacer textiles - Terms and definition, sample preparation, is the first standard of the new series of standards and contains specifications for the consistent marking and sample preparation of spacer fabrics. The document was prepared by the working committee NA 106 02 11 AA "Test equipment and test methods for spacer textiles" in the DIN Textile and Textile Machinery Standards Committee under the chairmanship of ITA employee Christoph Peiner.

Besides, documents on further standardized test methods for air permeability and thickness of spacer fabrics are planned. In addition, a publicly funded follow-up project focusing on further test procedures is planned. Please contact Christoph Peiner, e-mail christoph.peiner@ita.rwth-aachen.de, if you are interested in testing spacer fabrics and the standardised test procedures.

Aachen Summer School: Textiles become smart through 3D printing and origami

From 21 to 29 September 2026, the Aachen Summer School will transform Institut für Textiltechnik (ITA) of RWTH Aachen University into a laboratory of the future: over the course of a week, students will use origami folding techniques and 3D printing to develop active textile structures capable of performing programmable movements. This interdisciplinary event combines theoretical foundations with practical prototyping – from digital modelling right through to functional textile prototypes.

ITA has developed a washable digital smart jacket with real-time feedback and an AI-powered app for rehabilitation

As part of the PhysioTaix research project, the Institut für Textiltechnik (ITA) of RWTH Aachen University is developing a digital smart jacket with integrated sensors. The jacket is washable and reusable; it tracks movements during rehabilitation exercises in real time and transmits the data to an app.

DITF develops bio-based binding fibers for wood-fiber insulation materials

As part of the CelluWoodFlex project, the German Institutes of Textile- and Fiber-Research in Denkendorf (DITF) are developing bio-based cellulose ester fibers as alternative binding fibers for flexible wood fiber insulation materials. In addition to the spinning process and the production of suitable staple fibers, the institute is also investigating how wood and cellulose fibers can be separated and recycled at the end of their useful life.

POLYMERS-5B develops high-performance bio-based polyesters from agricultural waste

The European research project POLYMERS-5B is developing an integrated enzymatic biorefinery to convert agricultural by-products from Mediterranean food production into valuable raw materials for the food, cosmetics and bio-based plastics industries. Using tomato and olive pomace as feedstock, the process aims to recover several product groups from the same biomass stream. The consortium will present its latest technical developments and market findings at Ecomondo 2026 in Rimini on 3 November.

STFI showcases new Textile LAB Professional with focus on climate protection and sustainable technologies

The Sächsisches Textilforschungsinstitut e. V. (STFI) in Chemnitz is organising a themed day on 3 December 2026, focusing on climate protection and the environment. As well as showcasing current applications for green cities and natural fibres for lightweight construction, the event will feature machine demonstrations in the new Textile LAB Professional. Under the motto ‘Design meets Technology’, this networking event will also provide an insight into artistic student projects, thereby facilitating a professional exchange on creative perspectives and modern technologies for climate protection and the environment.

25 years of medical devices: ITVP combines experience with innovation

ITV Denkendorf Produktservice GmbH (ITVP) is celebrating its 25th anniversary. On October 1, 2001, ITVP was founded as a subsidiary of the German Institutes of Textile and Fiber Research Denkendorf (DITF), Europe’s largest textile research center. This spin-off company made it possible to consolidate expertise in medical technology and significantly expand production, which had previously been initiated mostly in the DITF’s cleanrooms.
