A laminate is claimed, having a first cover layer, a fabric with perforations as the middle layer, and a second cover layer, as are a method for its production and the use of the laminate as a fluid absorption and distribution layer made of a nonwoven fabric layer oriented in the Z direction, for absorbent hygiene articles. A three-dimensional form is achieved in that the fabric is present in the shrunk state in the middle layer, i.e. is brought into this state.
