Abstract: This invention relates to a method of making a film-fabric composite (includinng a film-fabric laminate) wherein the fabric is characterized as having improved tensile elongation (without rupture). In particular, the invention pertains to a method of making a film-fabric laminate having structual elastic-like behavior wherein the fabric is a nonwoven thermally bonded fabric characterized as having improved high strain rate tensile elongation and comprises a plurality of fibers comprised of at least one polypropylene polymer and at least one ethylene polymer, wherein the method comprises stretching the laminate at a high strain rate. The improved farbic is characterized by higher high strain rate tensile properties and a broader bond window which is also shifted to substantially lower temperatures with regard to maximum tensile properties.

Abstract: A corotating multiple-screw extruder comprising first and second intermeshing screws of more than one flight. The first screw comprises first and second segments paired with first and second segments of the second screw, respectively. On the first segment of the first screw, the height of the first flight is less than the height of the second flight and on the second segment of the second screw, the height of the first flight is less than the height of the second flight and screws for use in such extruder.

Abstract: A multiple-screw extruder in which paired co-rating screws, or segments thereof, contain unequal numbers of flights; and a screw for use in such extruder.
