Abstract
A process for producing a filament assembly composed of a thermotropic liquid crystal polymer, which comprises melt extruding a thermotropic liquid crystal polymer through an orifice nozzle into a high-speed fluid to thereby hold filaments spun right under the spinning nozzle at a high temperature, so that the filaments are taken up at a high draft ratio by the frictional force of the high-speed fluid.
Claims7
A filament assembly comprising a plurality of mutually entangled long-fiber filaments of a thermotropic liquid crystal polymer wherein each of the filaments is flexed or curled and has an average radius of curvature of 50 mm or less.
