ABSTRACT:
The invention concerns a method for producing a complex nonwoven fabric which consists in continuously producing a complex wherein a first web of a cellulosic fibres is continuously sandwiched between two webs of spunbonded filaments, and which consists in: producing a first web of spunbonded filaments, the bundle of extruded and drawn filaments being received on a mobile conveyor belt in the form of a non-bonded lap; depositing on said web by airlaid process a second web of cellulosic fibres; depositing on the textile web a second web of non-bonded continuous filaments; transferring the resulting complex onto an installation for water-jet bonding and hydro-entanglement consolidation; and in drying the nonwoven mixed product and then recuperating it, for example in the form of a cloth wind-up.
