It also relates to an insulation material comprising a foam, and the cellulose fiber-based sheet, the layer comprising untreated pulp of which has a grammage of at least 50 g/m²; a food packaging material comprising the cellulose fiber-based sheet, the layer comprising untreated pulp of which has a grammage of 30 to 90 g/m²; and a corrugated packaging material comprising an inside and outside liner comprising the cellulose fiber-based sheet.
Cellulose fiber-based sheets are provided herein. The sheets are particularly useful for insulation, construction and/or packaging material. A cellulose fiber-based sheet comprises a layer comprising untreated pulp impregnated with cationized vegetable wax. The cellulose fibers can be provided with a cationized vegetable wax thereby modifying the sheet to the extent that a hydrophobic surface is formed. The cationized vegetable wax attaches to the fluffy, fibrous surface of the sheet and seals the surface so that the so-called lotus effect is observed. The material is environmentally friendly, sustainable and imparts water repellence and a water vapour barrier to insulation materials, construction materials, packaging materials and the like.

FILTER MATERIAL AND FILTER MATERIAL COMBINATION FOR SEPARATING LIQUIDS AND FILTER ELEMENTS PRODUCED THEREFROM
A filter material for separating liquids from fluid flows comprises a wet- or dry-laid nonwoven, woven fabric, or an open-cell foam. The two sides of the filter material are impregnated with two different binders in such a way that one side of the filter material has a higher amount of surface energy and thus a shorter drop sink-in time than the opposite side.
The invention relates to a method for producing impregnated filter material from a woven fabric, a dry-laid nonwoven or a wet-laid nonwoven and a particulate binder, and to impregnated filter material obtainable by this method.
