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/m, its density being 0.18 to 0.28 g/cmand the 5% modulus value in the machine direction being &#x3e;60 N/5 cm, but at least 0.6 Nm/g.

Tufted backing and method of manufacturing same

Spun nonwoven fabric and apparatus for the manufacture thereof

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.

Device for producing spunbonded nonwovens

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.
