摘要

Producing fabrics comprising woven fabrics with adjusted permeability of yarns, threads or filaments, comprises using the structure of the fabric with polyester-, polyamide- or polyolefin threads, -yarns or -filaments; thermally or chemically degrading the polylactide threads, -yarns or -filaments in the finished fabric; and removing the decomposition products from the fabrics.
