BIKOMPONENTENFASERN VOM MATRIX/FIBRILLEN-TYP, VERFAHREN ZU IHRER HERSTELLUNG UND IHRE VERWENDUNG

摘要

A conjugate polycarbonate fiber comprising 95% to 50% by weight of a polycarbonate component and 5 to 50% by weight of a polypropylene component wherein ultrafine fibers composed of the polypropylene component are dispersed and arranged in a bundle-like form in the polycarbonate component as the fiber matrix, whereby the crazing resistance and oil resistance are improved. The conjugate polycarbonate fiber can be made into fibrous sheets and non-woven fabrics. The non-woven fabrics are adapted to be used as insulating layers in electric power cables.
