Abstract: A tufted backing and a method of manufacturing a tufted backing from thermoplastic polymer fibers or filaments that are processed to yield a spunbonded nonwoven are described, the spunbonded nonwoven containing only fibers or filaments having a titer of 1 to 15 dtex, the mass per unit area of the tufted backing being 70 to 110 g/m2, its density being 0.18 to 0.28 g/cm3 and the 5% modulus value in the machine direction being >60 N/5 cm, but at least 0.6 Nm2/g.

Abstract: A spun nonwoven fabric contains monofilaments and bicomponent filaments, the spun nonwoven fabric having, over its cross section, different quantities of the bicomponent filaments. The bicomponent filaments contain at least two outward-facing segments made of a binding component. The proportions of bicomponent filaments over the cross sectional planes of the spun nonwoven fabric can be in a range of approximately 1% to 100% by weight. The cross sectional planes of the nonwoven fabric containing the different proportions of bicomponent filaments transition into one another without detectable phase boundaries. The apparatus for manufacturing the nonwoven fabric contains at least one, and may contain up to forty or more, spinneret devices, such as rectangular spinneret plates or round spinneret disks. The spinneret devices may be arranged in rows or in staggered arrangement above a linearly moving collector belt.

Abstract: Rectangular or round spinning nozzle packs for extruding thermoplastic filaments each have both melt channels and orifices for the higher melting polymer compound and also melt channels with orifices through which is passed a polymer compound that melts at a temperature 5 to 50.degree. C. lower. Variously designed insulation channels thermally separate these melt channels, which are operated at different temperatures.

Abstract: The apparatus for manufacturing the nonwoven fabric contains at least one, and may contain up to forty or more, spinneret devices, such as rectangular spinneret plates or round spinneret disks. The spinneret devices may be arranged in rows or in staggered arrangement above a linearly moving collector belt. Spinning orifices on the spinneret devices are respectively dedicated to producing a monofilament or a bicomponent filament from a melt and, viewed in the direction of motion of the collector belt, are arranged with respect to one another so as to correspond in their totality to the cross sectional structure of different filament types in the nonwoven fabric.
