Abstract: 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 fibers selected from amongst synthetic fibers, regenerated fibers and natural fibers, 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 fibers 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.

Abstract: A hydroentangled integrated composite nonwoven material, includes a mixture of randomized continuous filaments, splittable shortcut staple fibers, and optionally non-splittable staple fibers. The splittable fibers should be 3-16 mm long bicomponent fibers. Preferably there should be no thermal bonding points between the filaments. The nonwoven material has improved textile feeling and reduced two-sidedness. The continuous filaments should preferably be spunlaid filaments. Some of the staple fibers can be colored. A process of producing such a nonwoven material is disclosed.

Abstract: A hydroentangled nonwoven sheet material produced by a process including: 0) optionally providing a polymer web on a carrier; a) providing an aqueous suspension containing short fibers and a surfactant; b) depositing the aqueous suspension on the carrier; c) removing aqueous residue of the aqueous suspension deposited in step b) to form a fibrous web; b′) depositing aqueous suspension on a surface of the fibrous web formed in step c); c′) removing aqueous residue of the aqueous suspension deposited in step b′) to form a combined fibrous web; d) hydroentangling the combined fibrous web; and optionally e) drying the hydroentangled web, and/or f) further processing and finalizing the dried, hydroentangled web the web to produce the nonwoven end material. The hydroentangled non-woven sheet material obtainable by this process has a low degree of surface irregularity and contains low residues of surfactants.
