Abstract

Polyolefin fibers and polyolefin yarns of high strength and elongation and textile fabrics produced therefrom. Polyolefin fibers and polyolefin yarns of high strength and elongation and textile fabrics produced therefrom, which consist of modified propylene polymers, unmodified propylene polymers and adjuvants, are produced by melting the polyolefin mixtures in the extruder, transferring the melt by extrusion pumps to the spinnerets and drawing off the extruded filaments by high-speed galettes and/or winders. The polyolefin fibers and polyolefin yarns of high strength and elongation and the textile fabrics produced therefrom are suitable for the production of textiles for the home, multilayered textiles, industrial textiles, nonwoven materials in medicine and hygiene and elastic hygiene articles.
