发明名称 Nonwoven fabrics with high fluid absorption capacity and a regular structure, process for their production, and their use
摘要 A three-dimensionally structured fiber fabric has a high fluid absorption capacity of at least 5 g fluid per g of fiber fabric and elevations and depressions that occur alternately and regularly with reference to the fabric plane, which includes at least one nonwoven fabric layer and a shrunk fabric bonded to it. The bond between the nonwoven fabric layer and the shrunk fabric has been produced by hot bonding, and the hot bonding occurred at least perpendicular to the direction of the greatest shrinkage of the shrunk fabric, in the form of regularly arranged lines. Furthermore, spaces have formed between the nonwoven fabric layer and the shrunk fabric, at the alternately occurring elevations and depressions, which spaces promote the fluid absorption capacity of the fabric. These fabrics may be used as wiping cloths, wet wipes, as fluid dispensers for cleaning or for applying fluids, etc.
