Abstract:
1. A method for producing a complex nonwoven fabric which consists in continuously producing a complex in which a fibrous web based on cellulosic fibers is sandwiched between two webs of continuous filaments, the method comprising: producing a first web of continuous filaments, wherein a bundle of extruded and drawn continuous filaments of the first web is received on a moving conveyor belt in the form of a nonbonded lap; depositing on the first web, by the airlaid technique, a second web of cellulosic fibers; depositing on the second web a third web of nonbonded continuous filaments wherein the depositing on the first web and the depositing on the second web forms a complex; transferring the complex onto a water-jet bonding unit and consolidating the complex by hydro-entanglement; and drying the nonwoven produced by consolidating the complex and taking it up in the form of a wound package.
