Process for simultaneously and continuously strengthening and coating a fleece fabric

Abstract

Abstract 1. A process for continuously consolidating a nonwoven and simultaneously coating it with a binder and with an adhesive composition, in which process the binder is synchronously counter-printed from one side against the adhesive composition, printed on from the other side, in the form of matching part-surfaces, the part-surfaces being spaced apart from one another, characterised in that a binder crosslinkable by ultraviolet radiation is printed onto the nonwoven from the underside by means of a relief-printing, planographic printing or gravure-printing cylinder having a soft, resilient rubber covering, that a thermoplastic adhesive composition ist printed onto the nonwoven from the upper face by the powder dot or screen printing process and that subsequently the nonwoven is irradiated with light which contains 10 to 30% of its total energy in the form of ultraviolet radiation, the total power being so chosen that the binder becomes crosslinked and the geometrical distribution of the adhesive composition becomes intrinsically stabilised, after which the nonwoven receives a final treatment by drying and/or sintering of the adhesive composition.
