Summary:PURPOSE: A side-by-side type conjugated hollow yarn, a spinning nozzle for producing it and a preparing method thereof are provided which have excellent crimp property and compression resistance. CONSTITUTION: The spinning nozzle is characterized by containing more than one single-slit type nozzle(10) having one discontinuous part(20) on circular type. The preparing method is characterized by: extruding two classes polymer having different viscosity through the nozzle; dividing the nozzle into one opening part containing the discontinuous part and the other opening part not containing the discontinuous part; extruding polymer having relatively high viscosity(Ph) through the one opening part containing the discontinuous part; and extruding polymer having relatively low viscosity(Pl) through the other opening part.
