Abstract

Se proporciona una lamina compuesta que incluye una primera capa fibrosa que tiene un primer lado y un segundo lado opuesto, y una segunda capa fibrosa unida al primer lado de la primera capa fibrosa. La primera capa fibrosa es una tela fundida de componentes multiples constituida de por lo menos 95% en peso de fibras fundidas que tienen un diametro efectivo promedio menor de 10 micrometros. La tela fundida esta constituida de 10% a 98% en peso de polietileno y de 90% a 2% en peso de un polimero que forma una fibra sintetica que tiene una temperatura de fusion mayor de 140°C a una temperatura de transicion vitrea de por lo menos 40°C. La segunda capa fibrosa esta constituida de por lo menos 95% en peso de una segunda capa de fibras que tienen un diametro efectivo promedio que es mayor que el diametro efectivo promedio de las fibras fundidas de la primera capa fibrosa. La lamina compuesta tiene un peso base menor de 120 g/m2, una resistencia a la traccion de sujecion de por lo menos 35 N, y una carga hidrostatica de por lo menos 10 cm.
