Abstract: An apparatus for extruding molten polymeric material into a plurality of filaments. The apparatus includes a pack which has a distribution plate and a circular spinneret positioned below the distribution plate. A quenching head is carried within and below the circular spinneret and includes a plurality of concentric hubs carried on a cylindrical tubular main body. Each of the concentric hubs has an upwardly inclined wall adjacent an upper portion of the hub which defines an incline annular passage which extends upwardly towards the spinneret through which quenching air is fed from the cylindrical tubular body through the passages for cooling the filaments being produced by the spinneret.

Abstract: A multilayer fabric includes a first fabric and a second fabric superimposed onto each other. The first fabric is a non-woven fabric comprising a plurality of crimped filaments, the crimped filaments including a plurality of crimps. The first and second fabrics are constrained to each other at a plurality of constraining points or zones, wherein the surface of the second fabric has an area greater than the area of the first fabric. At least one portion of the second fabric disposed between adjacent constraining points or zones, has a plurality of bulgy zones, the bulgy zones protruding outward from the surface of the multilayer fabric.
