Abstract

Fibras de polipropileno que comprenden una estructura de revestimiento-núcleo con una zona superficial que comprende una superficieexterna de la fibra que comprende una concentración elevada de material poliméricodegradado por escisión de cadena oxidativa en comparación con unaporción no degradada interna, y por lo menos 7% en peso de moléculas tienen un peso molecular superior a 5 x 10 Exponente 5. El procedimiento para prepararlas fibras comprende laextrusión del material que contiene polipropileno que tiene una amplia distribución de peso molecular para formar un extruidocaliente que tiene una superfice, y enfriar el extruido caliente en una atmósfera oxidativa para efectuar ladegradación por esci sión de cadenaoxidativa de la superficie para obtener una fibra que tiene un régimen de flujo de fusión promedio superior en comparación con el régimen de flujo de fusiónpromedio de una porción no degradada de la misma. Seprovee además un material no tejido formado por las fibras térmicamente fijadas entre sí y productoshigiénicos, tal como un panal que comprende el material no tejido formado por las fibras.
