摘要
The invention concerns a method for producing a complex nonwoven fabric which consists in continuously producing a complex wherein a first web of cellulosic fibres (4) is continuously sandwiched between two webs of spunbonded filaments (2, 7), and which consists in: producing a first web of spunbonded filaments (2), the bundle of extruded and drawn filaments being received on a mobile conveyor belt (3) in the form of a non-bonded lap; depositing on said web (2) by airlaid process a second web of cellulosic fibres (4); depositing on the textile web (4) a second web (7) of non-bonded continuous filaments; transferring the resulting complex onto an installation (9) 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 (18).
