In this DFG project we analyze warp knited spacer fabrics. Warp knitted spacer fabrics are double knit textiles, in the form of plates or shells that consist of two separate layers of knit fabrics joined by vertical spacer filament yarn. They are used in various products, the areas of application include, for example, the materials used in mattresses and seats.
Through the textile production process and the selection of the thread material the properties of the warp knitted spacer fabrics are variable and adjustable. Up to now the appropriate dimensioning has been possible yet by means of an extremely time-consuming and cost-intensive experimental technique. Furthermore, deformations of the structure generated by reprocessing and using will not be considered at present. This results in problems in fitting accuracy and changed insulation and flowing behaviour of the 3D fabrics as well as the ready-madefunctional components or products.
