Abstract

Ein Spinnvliesstoff besteht aus Mono- und Bikomponentenfilamenten und enthält über seinen Querschnittsverlauf unterschiedliche Mengen an Bikomponentenfilamenten. Diese enthalten mindestens zwei nach außen weisende Segmente (2) aus dem Werkstoff der bindenden Komponente. Über den Verlauf des Querschnitts des Spinnvliesstoffs können die Gehalte an Bikomponentenfilamenten 1 bis 100 Gew.-% betragen. Die unterschiedliche Anteile an Bikomponentenfilamenten aufweisenden Querschnittsebenen des Vliesstoffs gehen dabei ohne erkennbare Phasengrenzen ineinander über.
Die Vorrichtung zur Herstellung des Spinnvliesstoffs enthält 1 bis 40 rechteckige Spinndüsenplatten (3) oder runde Spinnscheiben (4); sie befinden sich aufgereiht oder in gestaffelter Anordnung über einem linear bewegten Auffangband (7). Die Spinnlöcher (5), (6) auf den Spinndüsenplatten (3) oder Spinnscheiben (4) sind jeweils der Erzeugung eines Monofilaments oder eines Bikomponentenfilaments aus der Schmelze gewidmet und, in Laufrichtung des Auffangbandes (7) gesehen, in ihrer Gesamtheit entsprechend dem Querschnittsaufbau an unterschiedlichen Filamentarten im Vliesstoff zueinander angeordnet.

Figure 00000001
A spunbonded nonwoven consists of mono- and bicomponent filaments and contains different amounts of bicomponent filaments over its cross-sectional shape. These contain at least two outwardly facing segments (2) made of the material of the binding component. The contents of bicomponent filaments can amount to 1 to 100% by weight over the course of the cross-section of the spunbonded nonwoven. The different proportions of cross-sectional planes of the nonwoven having bicomponent filaments merge with one another without recognizable phase boundaries.
The device for producing the spunbonded nonwoven contains 1 to 40 rectangular spinneret plates (3) or round spinning disks (4); they are lined up or in a staggered arrangement above a linearly moving catch belt (7). The spinning holes (5), (6) on the spinneret plates (3) or spinning disks (4) are each dedicated to the production of a monofilament or a bicomponent filament from the melt and, viewed in the running direction of the collecting belt (7), in their entirety in accordance with the cross-sectional structure arranged on different types of filaments in the nonwoven.
