Meeting of the Scientific Advisory Board at TFI

On 14.06.2022, after two years of the pandemic, our Scientific Advisory Board was finally able to meet again in person. We were pleased about the helpful discussions and important tips from the participants on our research ideas. In addition, we were able to show how we were able to expand our infrastructure during the two years - despite the pandemic. We were also fortunate to be able to present our new website at the same time. For the user, we have revised and modernised our website in terms of design, structure and content, and integrated new features in which the customers can also actively participate.

TFI launches new research project

The development of a digital material twin builds on the results of the digital process twin and extends the tufting simulation to include the material components. For this purpose, the decisive material parameters (yarn/carrier material, stitch density, gauge, etc.) are identified, analyzed for their measurability, and then transferred to an AI model and evaluated. The aim is a resource-efficient use of machines and personnel to support the time- and cost-intensive development of new tufting products.
