Abstract: The present disclosure relates to a spinneret plate for extruding fibers. The spinneret plate comprises a plurality of apertures configured thereon. Each of the plurality of apertures has a plurality of elongated arcuate slots grouped around a central point of each of the plurality of apertures to form a capillary. The plurality of elongated arcuate slots extends in the outward direction from the central point of connection of the plurality of elongated arcuate slots, to subtend a pre-determined angle therebetween and enable the extrusion of the fibers of a non-uniform cross-section therefrom. The polymeric fibers extruded from the plurality of apertures have a better wicking tendency as compared to that extruded from a plurality of apertures having a circular cross-section, thereby absorbing a desired color efficiently during the dying process to obtain fibers of the desired color.
