Abstract:
The present invention relates to a process for making a fibrous web comprising a plurality of first areas comprising hydroentangled fibers, the first areas being discrete in a machine direction and/or a counter-machine direction, the process comprises subjecting a fibrous web to a hydroentanglement process directing water jets from a water injection means on to the fibrous web, and blocking at least one of the water jets from the water injection means discontinuously using a first blocking member positioned between the water injection means and the fibrous web wherein the first blocking member comprises at least one aperture, or at least one recess on its surface, and is rotatable about an axis perpendicular to a z-direction.
