SIDE-BY-SIDE TYPE CONJUGATED HOLLOW YARN, PINNING NOZZLE FOR PRODUCING IT AND PREPARING METHOD THEREOF

摘要

PURPOSE: Provided are a side-by-side type conjugated hollow yarn, a spinning nozzle for producing it and a preparing method thereof having excellent crimp property and compression resistance. CONSTITUTION: The spinning nozzle is characterized by containing more than one two-slit type nozzle which is formed with the first semicircular type slit(1) and the second semicircular type slit(2) having two discontinuous parts on discontinuous circular type. The preparing method is characterized by: extruding two classes polymer having different viscosity through the spinning nozzle; and passing the polymers through the slits, followed by conjugating.
