The invention relates to a fiber laminate comprising two supporting fleeces and an absorptive fiber material which is disposed between the two supporting fleeces and is strengthened by means of a hydroentanglement process. Also disclosed are a method and a device for producing such a fiber laminate. The inventive fiber laminate is provided with sufficient stability against delamination and great absorptive capacity. Zones with absorptive fiber material and zones in which the two supporting fleeces are in direct contact with each other are provided between the two supporting fleeces across the area of the fiber laminate such that zones are created in which the two supporting fleeces forming the outer layers are directly connected to each other.
L'invention concerne un stratifié de fibres comprenant deux supports non-tissés et une matière à fibres absorbante disposée entre ces deux supports, ce stratifié se solidifiant par enchevêtrement par eau. L'invention concerne également un procédé et un système pour produire ce stratifié de fibres. Le stratifié de fibres selon l'invention présente une stabilité suffisante vis-à-vis de la déstratification et un pouvoir absorbant élevé. A cet effet, ce stratifié de fibres présente sur toute sa surface des zones comprenant de la matière à fibres absorbante entre les deux supports non-tissés et des zones dans lesquelles les deux supports non-tissés se trouvent directement l'un contre l'autre, ce qui permet de créer des zones dans lesquelles les deux supports non-tissés qui forment les couches extérieures sont liés directement l'un à l'autre.
