The spinneret, for the continuous melt spinning of a polymer, has a number of extrusion openings arranged in several identical fields. Each field has an asymmetry with a lateral shift of the far section (17) in relation to the remainder (18) of the openings. Also claimed is a spun filament, cooled and set after extrusion through the spinneret, from a polymer derived from lactic acid (PLA), to be used in a nonwoven. |
