A composite can include cellulose fiber; and foam binding the cellulose fiber. A method for manufacturing a composite can comprise mixing a plurality of ingredients to form a pre-foam mixture; foaming the pre-foam mixture to produce a foam; mixing the foam with cellulose fiber to form a composite material; and curing the composite material.

A cleaning sheet includes a base paper sheet that is impregnated with an aqueous agent. The aqueous agent includes butyldiglycol that is a glycol ether.

A water-dispersible composite structure, which comprises one or more layers, and a method of producing the same. At least a part of the layers is formed by a fibrous web or sheet containing 50-90 parts by weight of wood fibers and 10-90 parts by weight of annual or perennial plant fibers and/or 10-50 parts by weight of synthetic short-cut fibers, and 0.1-20% by weight of a binder, calculated from the weight of the fibers, and at least a part of the binder being a water-soluble polymer and another part a water dispersible binder, and the fibrous sheet or web being produced by wet forming. By means of the invention, the fibers of the composite structure can be recovered and recycled by equipment conventionally used in the paper and paperboard industry.

A manufacturing method of a paper, board or the like having a grammage in a range of 125-600 g/m.sup.2, preferably 150-210 g/m.sup.2, including adding a paper sizing agent including maleated vegetable oil and an alkenyl succinic anhydride (ASA) to a fibre stock including at least 80 weight-% of recycled fibre material and having calcium concentration of at least 500 mg/l, expressed as CaO.
