Abstract

Un textil no tejido para soporte de membrana semipermeable que comprende fibras sintéticas orgánicas como un componente primario, en el que una membrana semipermeable se apoya en una superficie del textil no tejido, caracterizado porque la fibra sintética orgánica consiste en una fibra de poliéster que tiene una longitud de 1 a 8 mm, el textil no tejido es un textil no tejido aplicado en húmedo sometido a un proceso de prensado en caliente, con una densidad de 0,5 a 1,0 g/cm3, un gramaje de 30 a 200 g/m2 y un espesor de 30 a 400 μm, una superficie recubierta a recubrir con la membrana semipermeable y una superficie no recubierta que es 10 opuesta a la superficie recubierta del textil no tejido tienen una lisura Bekk de 5 segundos, o más, en la que la lisura Bekk se basa en JIS P 8119: 1998, "Paper and Board Paper - Method for Testing Smoothness by Bekk Smoothness Tester", y el textil no tejido tiene una resistencia a la adhesión interna en una dirección transversal de la lámina en un intervalo de 0,4 a 0,8 N·m. en el que la resistencia a la adhesión interna se basa en el procedimiento JAPAN TAPPI para el análisis de papel y pulpa No. 18-2: 2000 "Paper and board paper - Method for testing internal bond strength, Part 2: Internal Bond Tester Method", cualquier superficie del textil no tejido puede recubrirse con la membrana semipermeable, las fibras que se pueden incorporar en el textil no tejido son solo fibras sintéticas orgánicas, y las fibras sintéticas orgánicas contienen una fibra constitutiva principal y una fibra aglutinante, y una relación de mezcla de la fibra constitutiva principal con la suma de la fibra constitutiva principal y la fibra aglutinante {fibra constitutiva principal/(fibra constitutiva principal + fibra aglutinante)} del 50% en masa, o más, e inferior al 100% en masa.
