Abstract

FIBRAS Y FILAMENTOS DE UNA POLIOLEFINA DE PSO MOLECULAR MUY ALTO, QUE TIENEN UN VOLUMEN DE HUECO MAYOR QUE 20 % APROXIMADAMENTE Y SON HUMECTABLES. LA HUMECTABILIDAD ES PROPORCIONADA A LAS FIBRAS Y FILAMENTOS INCORPORANDO UNA CARGA A LA COMPOSICION QUE ES HIGROSCOPICA, TIENE UN TAMAÑO DE PARTICULA MENOR QUE 10 (MU) DE DIAMETRO APROXIMADAMENTE Y UN AREA SUPERFICIAL MAYOR QUE 30 M2/G APROXIMADAMENTE. LAS CARGAS PREFERIDAS SON LAS QUE TIENEN GRUPOS SILANOL SUPERFICIALES. LAS FIBRAS Y FILAMENTOS SE FORMAN PREPARANDO UNA MEZCLA DE LA POLIOLEFINA DE PESO MOLECULAR MUY ALTO, CARGA Y PLASTIFICANTE, INTRODUCIR LA MEZCLA EN UN EXTRUSOR, CALENTAR Y AMASAR LA MEZCLA EN EL EXTRUSOR, PASAR EL EXTRUIDO A UN TROQUEL TIPO HILADOR, EXPRIMIR EL EXTRUIDO A TRAVES DE LAS ABERTURAS DEL TROQUEL PARA FORMAR FIBRAS Y FILAMENTOS Y EXTRAER UNA PARTE DEL PLASTIFICANTE EXTRAIBLE POR LO MENOS PARA PROPORCIONAR LA POROSIDAD DESEADA. LAS FIBRAS Y FILAMENTOS SE PUEDEN TRANSFORMAR EN TELAS TEJIDAS Y NO TEJIDAS POR TECNICASDE TENDIDO AL AIRE Y EN HUMEDO. TALES TELAS SON ESPECIALMENTE UTILES COMO SEPARADORES DE ACUMULADORES.
