Superficial fibrous formation of three-dimensional structure, exhibiting high fluid absorption properties, method of obtaining same and application thereof

摘要

Three-dimensionally structured fibrous sheet material with high liquid absorption of at least 5 g of liquid per g of fibrous sheet material, a thickness of at least 0,8 mm and is regularly in relation to the sheetlike structure which occur in an alternating elevations and depressions, which is arranged as the outer layer comprising at least one staple fiber gauze and an attendant, shrunk fabric, wherein the connection between the staple fiber gauze and the shrunk fabric by means of welding is carried out, wherein the welding is perpendicular to the direction of the strongest shrinkage of the shrunk fabric in the form of regularly arranged lines is effected, and wherein between the at least one outer layer, which is arranged as a staple fiber gauze and the shrunken structure with the alternately occurring elevations and depressions have formed, spaces, which convey the liquid absorption of the flat structure.
