The focus is on simulation methods that enable efficient predictions of the behavior of woven and knit textiles. Important parameters to be considered are
- the mechanical attributes of the individual weaving yarns
- and a suitable description of the mesh geometry.
Challenge Coefficients of Friction between Yarn Types
While the elongation properties of the individual fibers can be quite easily determined experimentally, determining the coefficients of friction between the various fiber types requires a much greater effort. The necessary fiber parameters are usually defined by suitably equipped experimental textile institutes and then provided to ITWM.
In this case, the main application area is especially in technical and medical textiles, which must strictly adhere to certain performance specifications. Some examples include: bandages that are supposed to exert pressure when in contact with the patient’s skin or, perhaps, there is a need to find a material specifically made to provide maximum protection, for example, either for a bullet proof vest or for work clothes like cut protective trousers.
Generally, the work of the textile group does not end with a specific textile product, rather more in the advanced development of appropriate simulation tools that the customer then uses to run various simulations – with changing materials or geometric parameters. Besides the evaluation of a specific textile design by simulation, the tools also enable the optimization of the performance characteristics for different design variants.
Clients from Various Industries
Our clients are among others producer of:
- compression bandages
- auto textiles
- protective safety systems of all kinds
- occupational and protective clothing
Other potential customers include companies that produce textiles in the broadest sense for use in the construction industry; for example, the materials built into drainage systems that must be able to withstand a certain pressure. In addition to the current focus on mechanical attributes of fabrics, other characteristics such as fluids transport will be studied in the future.
