<p>Only fibers or filaments with a weight of 1-15dtex are included in the tuft carrier. The weight/unit area of the tuft carrier is 70-110g/m<2>, density 0.18-0.28g/m<3> and the 5% modulus value in the processing direction is NOTLESS 60N/5cm and is preferably NOTLESS 0.6N/g/m<2>. An Independent claim is made for a process for production of the tuft carrier from a spun fleece of thermoplastic fibers or filaments. Fibers weighing 6-15dtex are needled together and those weighing 1-5dtex are hydrodynamically treated to consolidate. Prior to drying and setting the fleece is stretched longitudinally by NOTGREATER 30%, the relative movement of fibers being improved by addition of oil or other lubricants. Preferred Features: Preferred fiber or filament weight is 3-12dtex and 5% modulus value is 70-100N/5cm and NOTLESS 0.7-1.0N/g/m<2>.</p> |
