SPUN ISOTROPIC PITCH-BASED CARBON FIBER YARN, COMPOSITE YARN AND WOVEN FABRIC MADE BY USING THE SAME, AND PROCESSES FOR THE PRODUCTION OF THEM

摘要

A process for the production of a woven fabric of spun isotropic pitch-based carbon fiber yarn which comprises the step of winding a water-soluble polymer fiber on the surface of spun isotropic pitch-based carbon fiber yarn to form a composite yarn, the step of weaving the composite yarn into a composite yarn fabric, and the step of dissolving the water-soluble polymer fiber and thereby removing the polymer fiber from the composite yarn fabric to form a woven fabric of spun isotropic pitch-based carbon fiber yarn.
