    • 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 h 0 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 h 0 , wherein the first protuberances (2) have a height h 1 from the base level h 0 and the second protuberances (3) have a height h 2 from the base level h 0 , where h 2 is higher than h 1 , 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.
    • 本发明涉及一种用作吸收性擦拭材料的非织造材料,所述非织造材料通过将包含至少一层选自合成纤维,再生纤维和天然纤维的纤维的纤维素水解缠绕而制得,其中所述非织造材料(1)具有 在一侧具有突起(2,3)的底部水平面h 0,其中所述突起(2,3)分别以第一和第二表面结构形式形成第一和第二表面结构, 第二突起(3)从基底水平h 0 0 的突起,其中第一突起(2)具有与基底水平h 0 的高度h 2> 2,其中h 2 <2>高于h 1 ,并且每个第二突起(3)占据基底水平面的面积比第一突起(2)中的每一个大至少4倍。 本发明还涉及一种用于生产非织造材料(111)的方法,其中在表面形状的载体装置上进行包括长度小于10mm的天然纤维的基材网(101)的水力缠结( 109)包含分别形成第一和第二孔形式的至少第一和第二图案的孔,其中第二孔比第一孔大至少4倍。
