Patent ID: 7763339

Claim:
A three-dimensionally structured fiber fabric comprising: at least two nonwoven fabric layers; and a shrunk fabric bonded to the nonwoven fabric layers, a bond between each of the nonwoven fabric layers and the shrunk fabric produced by hot bonding at least perpendicular to a direction of greatest shrinkage of the shrunk fabric in the form of regularly arranged lines, cavities formed between the nonwoven fabric layers and the shrunk fabric layer at alternately and regularly occurring elevations with reference to a fabric plane, the three-dimensionally structured fiber fabric having a high fluid absorption capacity of at least 5 g fluid per g of fiber fabric and a thickness of at least 0.8 mm, at least a first of the two nonwoven fabric layers attached to a side of the shrunk fabric layer and a second of the two nonwoven fabric layers attached to a second side of the shrunk fabric layer, wherein each of the at least two nonwoven fabric layers has an undulation spanning between bonds bonding the shrunk fabric and the at least two nonwoven fabric layers, a profile of said undulation defined by two peaks, wherein facing surfaces of the at least two nonwoven fabric layers approach the shrunk fabric in between the two peaks.
