Abstract:

The possibility of using yarns of biodegradable polyester raw materials creates a new area of research works in knitted fabric technology. Because of the raw material characteristics and different properties of non-woven biodegradable materials, the knitted fabrics under investigation constitute a new generation of technological solutions. The research results presented above concern technological solutions for knitwear and dressing products made of a new generation of multifilament yarns of polylactide (PLA) and poly(glycolide-colactide) (PGLA). Due to the technological works a knitting technique was applied for the construction of the fabrics. Structural solutions for the fabrics were developed for medical dressings and hygienic dressing bands. The materials have biodegradable properties confirmed experimentally. The chemical purity of the materials was determined on the basis of medical product criteria.
