From idea to transfer
Functionalisation/Chemical analytics
Processes, Technologies, Products
Technical textiles achieve their tailor-made properties by surface functionalization like finishing, coating, functional printing or laser structuring as well as joining technologies like lamination. Developing novel products is always an interaction of material selection, structure engineering and manufacturing process as well as a close look on ecology and chemical analytics. In cooperation with the STFI research and testing field "Textile Factory of the Future" manufacturing processes are being further developed regarding to the realization of a complete value chain.

Fields of application
MeInPak – Development of sustainable, multi-layer and reprocessable PPE for a "reusable infection control package"
The aim of this joint project is the development of a multilayer material composite consisting of at least one filtering functional layer (meltblown nonwoven, foam coating or nanomembrane) in partial combination with each other or in combination with a textile. The developed composites are to be used to manufacture individually adapted protective masks and gowns that can be washed several times and comply with the PPE Ordinance and also dual use as a medical device.

Further projects
CarboCopTex
The objectives of the project are the development of conductive carbon black (carbon) and copper (copper) based formulations, which enable the generation of electrically conductive, dissipative and sensory structures on textile substrates and represent a significantly more cost-effective alternative to silver-based systems. In addition, the focus is on the development of single-layer and multilayer structures, taking into account textile-ink interaction and film formation between copper and carbon black layers.
