Abstract

LA INVENCION SE REFIERE A UNA HEBRA DE FIBRAS CORTAS Y MUY FINAS QUE TIENEN UNA RESISTENCIA A LA TRACCION, COMO MINIMO, DE 1 GPD Y UNA SUPERFICIE, MEDIDA CON EL METODO BET DE ADSORCION DE NITROGENO, MAYOR DE 2 M 2 /G. ESTAS FIBRAS CORTAS Y MUY FINAS ESTAN FORMADAS POR UN 20 % MINIMO, EN PESO, DE POLIETILENO Y POLIPROPILENO, EN DONDE EL POLIETILENO Y EL POLIPROPILENO COMPRENDEN, COMO MINIMO, UN 5 % EN PESO, DE CADA UNA DE ESTAS FIBRAS CORTAS Y MUY FINAS. TAMBIEN SE EXPONE UN PROCESO PARA FABRICAR TAL HEBRA QUE INCLUYE LAS SIGUIENTES FASES: SE FORMA UNA SOLUCION PARA HILAR DE POLIMEROS DE POLIETILENO Y POLIPROPILENO EN UN DISOLVENTE Y SE HACE GIRAR LA DISOLUCION A UNA PRESION DE GIRO SUPERIOR A LA PRESION AUTOGENA DE LA DISOLUCION DE HILADO, EN UNA REGION DE UNA PRESION SUSTANCIALMENTE INFERIOR, Y A UNA TEMPERATURA AL MENOS 50 (GRADOS) C POR ENCIMA DEL PUNTO DE EBULLICION ATMOSFERICO DEL DISOLVENTE.
