ABSTRACT:
The present invention is directed to a method of forming a heteroconstituent nonwoven web including a mixture of different filament types simultaneously formed into the same web. The filament types may differ as to polymer composition, additive loadings, fiber size, fiber shape, and/or degree of crimping. The invention is also directed to a method of forming a multilayered nonwoven structure in which different filament types constituting different layers are simultaneously formed.
