摘要 |
<p>A nonwoven material for use as an absorbent wiping material produced by hydroentangling of a substrate web including at least one layer of fibres selected from amongst synthetic fibres, regenerated fibres and natural fibres, wherein the nonwoven material has a base level h<SUB>0 </SUB>with protuberances on one side, the protuberances forming at least a first and a second surface structure respectively in the form of first and second from the base level h<SUB>0</SUB>. The first protuberances have a height h<SUB>1 </SUB>from the base level h<SUB>0 </SUB>and the second protuberances have a height h<SUB>2 </SUB>from the base level h<SUB>0</SUB>, where h<SUB>2 </SUB>is higher than h<SUB>1</SUB>, and each of the second protuberances occupies an area of the surface of the base level at least 4 times greater than each of the first protuberances. A method for producing the nonwoven material is also disclosed.</p> |
