Abstract

Process for the production of curled continuous or swollen or recessed nonwoven web structures consisting of these yarns by melting polypropylene, extruding, removing and drawing the yarns at high speed, and deposition on a collection device, characterized in that polypropylene with an i5 melt index of 50 to 500, measured at 230º c, is spun from spinning holes with diameters of 0.5 to 1.5 mm. To form 5 to 20 denier threads, these are cooled in transverse air flow and are removed and drawn with a tensile stress of at least 0.05 g/denier through a pneumatically working withdrawal device that is arranged at a distance of 4 to 15 m below the spinning holes, with a yarn removal speed of 2,500 m/minute up to 09,000 m/minute, and then the yarns are deposited on an air permeable collection device, which is under a depression of at least 50 mm of water column.
