Germany has come out with its first national test standards for spacer fabrics, developed by the Institut für Textiltechnik of RWTH Aachen University (ITA), in a joint project NormATex (Standardisation for Spacer Fabrics). The project has been funded by the Federal Ministry for Economic Affairs and Energy (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.Germany has come out with its first national test standards for spacer fabrics, developed by the Institut für Textiltechnik of RWTH Aachen University (ITA), in a joint project NormATex (Standardisation for 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. 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 or with conventional flat fabrics or non-textile materials cannot be made.
In the documents of this series of standards, the special properties of spacer fabrics are given special consideration. This ensures the standardised testing of these properties and objective comparisons between spacer textiles among themselves, spacer fabrics and flat 2D-textiles, and spacer fabrics and non-textile materials will be enabled.
The developed standardisation document, 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 in the DIN Textile and Textile Machinery Standards Committee under the chairmanship of ITA employee Christoph Peiner.
Documents on further standardised test methods for air permeability and thickness of spacer fabrics, and a publicly funded follow-up project focusing on further test procedures are being planned.
