Abstract
Various implementations include a spinneret plate defining a plurality of capillaries, including a first, second, and third capillary portions with a substantially hexagonal central area therebetween. The substantially hexagonal central area is joined to the spinneret plate by first and second legs being radially spaced apart and separate by a first apex of the substantially hexagonal area. A filament is formed by a polymer exiting the end of the capillary in three separate strands having the shape of the openings, and each strand bulges radially outwardly such that the strands merge together.
