description PROBLEM TO BE SOLVED: To provide a spinning nozzle and a spinning method with which polymers having a big difference in intrinsic viscosity are subjected to composite spinning and to carry out nonconventional high-crimp type stretch fiber spinning. SOLUTION: The method for composite spinning comprises independently feeding two kinds of polymers having different intrinsic viscosities to a spinneret, forming a conjugate flow at the upstream part of the discharge opening of the spinneret and discharging the conjugate flow from the discharge opening inclined by 10-45° to the side of a polymer having a smaller intrinsic viscosity in the direction vertical to a nozzle surface.
