NONWOVEN MATERIAL AND METHOD FOR PRODUCING NONWOVEN MATERIAL

摘要

The present invention relates to a nonwoven material for use as an absorbent wiping material produced by hydroentangling of a substrate web comprising at least one layer of fibres selected from amongst synthetic fibres, regenerated fibres and natural fibres, wherein the nonwoven material (1) has a base level h₀ with protuberances (2, 3) on one side, wherein the protuberances (2, 3) form at least a first and a second surface structure respectively in the form of first (2) and second (3) protuberances from the base level h₀, wherein the first protuberances (2) have a height h₁ from the base level h₀ and the second protuberances (3) have a height h₂ from the base level h₀, where h₂ is higher than h₁, and each of the second protuberances (3) occupies an area of the surface of the base level at least 4 times greater than each of the first protuberances (2). The present invention also relates to a method for producing a nonwoven material (111), wherein hydroentangling of a substrate web (101), which comprises natural fibres having a length of less than 10 mm, takes place on a surface-shaped carrier device (109) containing holes which form at least a first and a second pattern in the form of first and second holes respectively, wherein the second holes are at least 4 times larger than the first holes.
