Center of Excellence in Nonwovens

Processes, Technologies, Products

The Centre of Excellence in Nonwovens combines almost all nonwoven formation and solidification processes in the technology areas of nonwovens and extrusion fabrics. Comprehensive know-how and tailored pooling of excellence with other departments are important guarantees for successful processing of research and development work.

Voluminous filter media with high dimensional stability


09/2017-08/2019

The main task in a research project was to increase the dimensional stability of the filter material/pile fibre nonwoven fabric and to reduce the unbalanced strength and elongation behaviour towards MD:CD=1:1. This could be realised on the one hand by the additional spunlace layer applied to the mesh side of the Kunit nonwoven fabric, and on the other hand by the use of the Maliknit process, in which a crosswise laid fibre nonwoven is feeded into the Kunit machine (see Fig.). The testing of the filter materials in incineration plants on an industrial scale was carried out together with the project partners Institut für Luft- und Kältetechnik gGmbH, Dresden, and the company Endress Holzfeuerungsanlagen GmbH, Burgbernheim.
