Functionalisation/Chemical analytics

Technical Equipment

The STFI provides the whole development process: starting from developing formulations for functional dispersions and thermoplastics and their characterization to small-scale samples and the up-scaling to small-quantity manufacturing on semi-industrial pilot equipment.

An overview of our machinery equipment for surface functionalization and composite formation can be found here.

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.
