发明名称 Method for the production of nonwoven webs, the cohesion of which is obtained by means of fluid jets
摘要 The invention concerns a method for producing a nonwoven web formed at least partly with hydrophilic elementary fibers which consist in: producing by carding a textile layer (10) which is then compressed and moistened; subjecting it to a bonding treatment using water jets acting at least against one of its surfaces; and transferring said bonded layer to a unit (32, 33) to be dewatered and dried. Said method is characterised in that, after the bonding treatment (20) with water jets and before drying and delivery, the pre-bonded and moistened layer is transferred to a supplementary unit (28) to be treated by the action of one or several series of water jets, said unit comprising a mobile suction surface in the form of a drum covered with an open-work structure (30) consisting of a wire-mesh fabric, comprising successive raised and recessed zones.
