摘要：
The present invention relates to a nonwoven material for use as an absorbent wipingmaterial produced by hydroentangling of a substrate web comprising at leastone layer of fibres selected from amongst synthetic fibres, regenerated fibresand natural fibres, wherein the nonwoven material (1) has a base level hwith protuberances (2, 3) on one side, wherein the protuberances (2, 3) form atleast a first and a second surface structure respectively in the form of first(2) and second (3) protuberances from the base level h, wherein thefirst protuberances (2) have a height h from the base level hand the second protuberances (3) have a height h from the base levelh, where h is higher than h, and each of the secondprotuberances (3) occupies an area of the surface of the base level at least 4 timesgreater than each of the first protuberances (2). The present invention alsorelates to a method for producing a nonwoven material (111), wherein hydroentanglingof a substrate web (101), which comprises natural fibres having a length of lessthan 10 mm, takes place on a surface-shaped carrier device (109) containing holeswhich form at least a first and a second pattern in the form of first and second holesrespectively, wherein the second holes are at least 4 times larger than the firstholes.
