Claims

[Scope of utility model registration request]

It consists of a combination of a lower metal plate having a group of discharge holes for the composite flow and an upper metal plate having a group of capillaries provided with discharge holes for the core component, and the capillary is inserted substantially tightly into the inner wall of the discharge guide hole for the composite flow. In a concentric type core-sheath composite fiber spinning spinneret, which has grooves on the outer periphery of the capillary that serve as passages for two or more sheath components, a group of capillaries is arranged in an annular region, and the sheath components are passed from the inside and outside of the spinneret. A gap is provided between the lower cap plate and the upper cap plate to serve as a passage for the sheath components in a wider area than the group of capillaries, so that the flow of the sheath components into the composite flow discharge guide hole, and a sheath opening in the gap is provided in the upper cap plate. A spinneret for spinning concentric core-sheath composite fibers, characterized by having component introduction holes.
