ABSTRACT:
The present invention is directed to a method of making a substantially continuous filament web which includes providing a plurality of polymer extruders for supplying polymer streams of at least two different polymer compositions, and providing a spinneret assembly for receiving the polymer streams. The spinneret assembly includes a plurality of orifices from which the polymer streams are extruded for formation of substantially continuous filaments formed from the polymer compositions. The distribution of at least one of the polymer compositions within the spinneret assembly is selected to optimize selected physical characteristics of the resultant continuous filament web.
