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.

digiTEX-PRO


09/2018 – 08/2021

Das Ziel dieses F&E-Vorhabens ist es, eine digital ansteuerbare flexible Ausrüstungstechnologie auf Basis von digitalen Verfahren aus der Druck- und Beschichtungsindustrie für die effiziente vollflächige und geometriegesteuerte Ausrüstung von textilen Flächen zu entwickeln. Mit Hilfe dieser Technologie wird es möglich sein mit Ressourcen rücksichtsvoller umzugehen, Umrüstaufwände an Ausrüstungsmaschinen zu reduzieren und kontaktlos Ausrüstungschemikalien präzise auf das Textil aufzubringen. Ein erster Maschinenprototyp wurde auf der ITMA 2019 in Barcelona vom Projektpartner Suchy Textilmaschinenbau GmbH vorgestellt.
