Nonwoven fabrics having high liquid absorption and regular structure, a method for their preparation and their use

摘要

Disclosed is a three-dimensionally structured fibrous sheet material with high liquid absorption of at least five grams of liquid per gram of fibrous sheet material and is regularly in relation to the sheetlike structure which occur in an alternating elevations and depressions, comprising at least one nonwoven fabric layer and an attendant, shrunk fabric. The connection between the nonwoven fabric and the shrunken flat article is in this case takes place by welding, and the welding is at least at right angles to the direction of the strongest shrinkage of the shrunk fabric in the form of regularly arranged lines is effected. Also, between the nonwoven fabric layer and shrunk structure with the alternately occurring elevations and depressions spaces, which convey the liquid absorption of the flat structure. Dollars a the sheet materials of the invention can be utilized in particular as wiping cloths, moist wiping cloths or as a liquid dispenser for cleaning or for the application of liquids insertion.
