Abstract
This invention relates to spinnerets having orifices of unique cross-sections, the spinnerets being useful for extruding therethrough filaments having "U" and "E" shaped cross-sections with stabilizing legs. The use of strategically placed stabilizing legs allow the filaments to maintain the desired shape. The "U" shaped filament cross-section provides improved drainage over previous filament cross-sections.
