SIDE BY SIDE TYPE POLYESTER CONJUGATED FILAMENT WITH EXCELLENT CRIMP PROPERTY AND PROCESS OF PRODUCING THEREOF

摘要

PURPOSE: A two-component hollow filament of side-by-side type and a method for fabricating the same are provided to ensure excellent bulk property and texture. CONSTITUTION: A method for manufacturing two-component hollow filament of side-by-side comprise: a step of separately supplying polyethylene terephthalate polymers and polytrimethylene terephthalate polymers to two extruders and melting; a step of extruding two kinds of polymers by a spinneret of two slit types; and a step of passing the polymer through a freezing unit and rolling.
