METHOD FOR PRODUCING FIBRIL-EXHIBITING HIGH-PERFORMANCE CHOPPED FIBERS, FIBRIL-EXHIBITING HIGH-PERFORMANCE CHOPPED FIBERS, AND ARTICLES CONTAINING THE SAME

摘要

A method for producing fibril-exhibiting high-performance fibers comprising the stepsa) providing an organic, high-performance filament yarn having a breaking tenacity of at least 10 g/dtex and a modulus of elasticity in extension of at least 150 g/dtex,b) fibrillation of the high-performance filament yarn in a dry yarn state, through which a fibril-exhibiting high-performance filament yarn results, andc) cutting the fibril-exhibiting high-performance filament yarn resulting from step b) into fibril-exhibiting high-performance chopped fibers of substantially the same length,fibril-exhibiting high-performance chopped fibers of substantially the same length, an article comprising said fibers and one or more fillers, and a method for producing such an article are presented.
