NOVEL ELASTIC WARP KNITTED FABRIC WITH PERFORATION
Technical University of Liberec
The aim of this project is to create novel elastic knitted materials with improved comfort for medical products. In this context, warp knitted structures were produced using different weft threads laying in. The elastic warp knitted fabric produced with transverse weft threads for the whole width was used as a reference sample. It is widely used in medical products. Laying in weft threads with a partial set according to a certain repeat allows us to get structures in which there is no connection in adjacent wales in certain places. This leads to the formation of through holes in the structure. As a result of increased permeability, comfort properties are improving. The structure, functional and comfort properties of developed and reference elastic warp knitted fabrics were investigated. It was found that novel elastic fabrics have higher values of comfort indicators and provide the necessary functional properties.
