Abstract

Es wird ein Verfahren zum Strukturieren einer Faservliesbahn durch einen Nadelungsvorgang beschrieben, bei dem die von den Nadeln ergriffenen Fasern der auf einem endlos umlaufenden Bürstenband abgestützten Faservliesbahn so tief zwischen die Borsten des Bürstenbandes gedrückt werden, daß die Haftreibungskräfte zwischen den Borsten und den zwischen ihnen befindlichen Fasern der Faservliesbahn ausreichend groß sind, daß ein Anheben der Faservliesbahn bei der Rückhubbewegung der Nadeln verhindert ist, so daß auf den Einsatz eines Niederhalters verzichtet werden kann. Die durch Erhöhung der Vorschubgeschwindigkeit hervorgerufene Verminderung der Einstichdichte in das Faservlies kann durch Vergrößerung der Bestückungsdichte am Nadelbrett kompensiert werden, wobei das Fehlen eines Niederhalters auch die Grenzen der Bestückungsdichte beseitigt (Fig. 1).

Figure 00000001
A method for structuring a nonwoven web by a needling process is described, in which the fibers of the nonwoven web supported on an endlessly rotating brush band, which are gripped by the needles, are pressed so deeply between the bristles of the brush band that the static friction forces between the bristles and those between them Fibers of the nonwoven web are sufficiently large that lifting of the nonwoven web is prevented during the return stroke movement of the needles, so that the use of a hold-down device can be dispensed with. The reduction in the puncture density into the nonwoven fabric caused by increasing the feed rate can be compensated for by increasing the placement density on the needle board, the absence of a hold-down device also eliminating the limits of the placement density (FIG. 1).
