The present invention is directed to a method of making a laminate nonwoven fabric which entails integration of a continuous filament web with a web of cellulosic fiber material, typically wood pulp. In order to abate loss of cellulosic fiber material during integration by hydroentanglement, the present invention contemplates that the continuous filament web is first subjected to hydroentanglement, with the cellulosic fibrous material thereafter integrated, by hydroentangling, into the partially entangled continuous filament web.

La présente invention concerne un procédé de fabrication d'un tissu non tissé laminé qui implique l'intégration d'une bande filamenteuse en continu avec une bande de matière de fibre de cellulose, normalement une pâte de bois. Afin de supprimer la perte de matière de fibre de cellulose pendant l'intégration par enchevêtrement, la bande filamenteuse en continu est d'abord soumise à hydro-enchevêtrement, la matière de fibre de cellulose étant par la suite intégrée par hydro-enchevêtrement dans la bande de filament en continu partiellement enchevêtrée.
