The development of new tufting products is associated with high material, time and personnel costs. Development times average 6-7 months for known materials and over 12 months for unknown materials.
The aim of the research project Resource T-EXDIZ is to transfer expert knowledge for the development of tufting products into digital form. An experimental digital material twin is used for this purpose. It enables advance simulation to improve product development and thus a more efficient use of physical resources. The basis for the project is provided by the findings of a project recently finalized from the research partner TFI (IGF 21166N), in which an experimental digital process twin of a tufting machine was developed. In the current project, this is being extended to include parameters for material properties of yarns and backings. For this purpose, the corresponding material properties (e.g. elongation, backing type), process parameters (e.g. pile height, needle stroke) and product properties (e.g. basis weight, pile density) are determined.
