Summary: | Cellulose fibre containing products in sheet or web form, such as paper and pulp sheets, are produced from a suspension of cellulose containing fibres, and optional fillers, to which is added anionic inorganic particles, such as bentonite and silica based particles, and a cationic carbohydrate polymer containing aluminium. The cationic carbohydrate polymers are cationic galactomannans or cationic starch. High cationized starch with a degree of substitution of at least 0.07 are especially suitable. |
