Abstract

The invention relates to a method for improving papermaking or board making process. The method comprises forming a fibre stock, and leading the fibre stock to a headbox and feeding it to a wire to form a wet fibrous web. A at least one polysaccharide having 1,4-beta-anomeric configuration in linkages between saccharide units of the polysaccharide backbone or the main polysaccharide backbone is applied to the fibre stock after machine chest or on the wet fibrous web. The invention relates also to paper made by the method and to the use of polysaccharide.
