Abstract
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.
