A spinneret for producing easily splittable plural-component fibers includes two passages (22, 26) for respectively delivery two incompatible polymers (A and B) to two sets of inclined capillaries (34-39, 46-51). The two sets of capillaries converge toward each other in a downstream direction and direct molten polymer streams to two respective rows of orifices. The centerlines of the polymer A capillaries lie along axes that, when extended beyond the spinneret, are offset and on-intersecting with axes along which the centerlines of the polymer B capillaries lie, such that the centerlines of the extruded polymer streams are directed along non-intersecting axes. The capillary angles and orifice arrangement cause the extruded polymer streams to extend toward each other in an interleaved fashion, with the polymer streams contacting each other in a generally tangential manner.
