Abstract

Der Werkstoff dieser Faser weist eine amorphe oder eine teilweise orientierte molekulare Struktur auf, wobei die Oberflächenstruktur Bestandteil einer geschäumten Schicht ist, welche einen Faserkern umhüllt, der im wesentlichen frei von Poren ist. Die Poren sind senkrecht zur Oberfläche orientiert, und ihr Querschnitt überdeckt bei einem Durch­ messer von 0,01 bis 0,5 µ 1 bis 99 % der gesamten Oberfläche. The material of this fiber has an amorphous or a partially oriented molecular structure, the Surface structure part of a foamed layer which envelops a fiber core that is essentially free of pores. The pores are perpendicular to the surface oriented, and their cross section overlaps at a through knife from 0.01 to 0.5 µ 1 to 99% of the total Surface.
