Abstract

1) Una fibra per tessuti non tessuti avente forza di termosaldatura uguale o superiore a 5 N e/o indice di flessibilità superiore a 800, comprendente un materiale polimerico, addizionato con fosfiti e/o fosfoniti organici, con HALS, ed eventualmente, con antiossidanti fenolici, detto materiale polimerico essendo scelto tra:1) omopolimeri del propene isotattico, avente un indice isotattico maggiore di 90;2) copolimeri random del propene con etene e/o con un'alfa-olefina C4-C8; e 3) miscele di polimeri (1) con copolimeri (2) e/o polimeri propilenici eterofasici, o loro combinazioni;detta fibra essendo ottenuta mediante un processo di filatura operando con portata foro da 0,1 a 0,6 g/minuto ed a temperatura di filatura da 260° a 320°C impiegando i polimeri (1) o (2) o le miscele polimeriche (3) aventi M.F.R. da 5 a 40 g/10 min.
