Abstract (en)

[origin: DE10009280A1] Material comprises a microfilament fleece of 50-200g/m<2> based on melt spun, stretched multi-component, continuous filaments with a weight/unit length of 1.5-5dtex. After >= 80% solidification the continuous filaments are split and simultaneously solidified to form micro continuous filaments with a weight/unit length of 0.1-1.2dtex. A thermoplastic material is then injection molded onto the fleece. An Independent claim is also included for a process for manufacturing the composite material in the fleece from continuous filaments, partially solidified and then subjected to high pressure fluid jets which complete the solidification and simultaneously split the filaments into micro filaments before backing with thermoplastic.
