摘要： The present invention is directed to a process for forming a plurality of multi-layered filaments from multiple thermoplastic synthetic polymers and an apparatus containing a melt spinning beam which comprises multiple polymer inlet passages each communicating with separate multiple coat hanger distribution manifolds, separate filters connected downstream of each coat hanger distribution manifold, a combining manifold connected downstream of the filters and containing channels to retard polymer flow across planar molten polymer flow streams and a spinneret comprising a plurality of spinneret exit orifices connected downstream of the combining manifold for spinning of the multi-layered filaments.
