Technical Textiles and Nonwoven

Modelling, simulation and optimization of the material behaviour of technical textiles and nonwovens are our core competences in this area. Our know-how consists in modelling and simulation of all possible technical textiles, i.e. warp and weft knitted, spacer fabrics, woven and nonwovens (e.g. made of stapled fibers, filaments, plastic (PET, PP, PA) or natural fibres (cotton, leather)).

We simulate their nonlinear thermomechanical properties: tension, bending, compression, visco-elastic, creep behavior and fatigue using homogenization and dimension reduction methods, reducing the problem complexity. In addition, we use simulations to evaluate the air permeability, acoustic absorption, moisture behavior or absorbency of textiles and nonwovens for any compression or deformation state.


Our Expertise Makes it Possible:

  • the accelerated development, virtual design and optimization of technical textiles and nonwovens
  • the qualified evaluation of the structure-property relationship and material properties of textiles
  • the automated textile machine control for the production of customized textiles
