Abstract
The present invention relates to a filler comprising calcium salt and cellulose derivative having a degree of substitution of net ionic groups up to about 0.65, wherein the filler is substantially free from fibres or fibrils of cellulose or lignocellulose. The invention also relates to a filler comprising calcium salt and a cellulose derivative having a degree of substitution of net ionic groups up to about 0.65, wherein the cellulose derivative contains cationic groups. The invention further relates to a method of producing a filler which comprises mixing a calcium salt-containing material with a cellulose derivative having a degree of substitution of net ionic groups up to about 0.65 in the substantial absence of fibres or fibrils of cellulose or lignocellulose. The invention also relates to a method of producing a filler which comprises mixing a calcium salt-containing material with a cellulose derivative having a degree of substitution of net ionic groups up to about 0.65, wherein the cellulose derivative contains cationic groups. The invention further relates to a filler obtainable by the methods. The invention further relates to a papermaking process which comprises providing an aqueous suspension containing cellulosic fibres, introducing into the suspension a filler comprising calcium salt and cellulose derivative having a degree of substitution of net ionic groups up to about 0.65, wherein the filler is substantially free from fibres or fibrils of cellulose or lignocellulose, and dewatering the suspension to form a web or sheet of paper. The invention also relates to a papermaking process which comprises providing an aqueous suspension containing cellulosic fibres, introducing into the suspension a filler calcium salt and cellulose derivative having a degree of substitution of net ionic groups up to about 0.65, wherein the cellulose derivative contains cationic groups, and dewatering the suspension to form a web or sheet of paper.
Claims (25)

18. The paper according to claim 17, characterised in that the total filler content of the paper is from 5 to 40 % by weight, based on dry paper.
19. A method of making a filler which comprises mixing a calcium salt-containing material with a cellulose derivative having a degree of substitution of net ionic groups up to about 0.65 in the substantial absence of fibres or fibrils of cellulose or lignocellulose.
20. A method of making a filler which comprises mixing a calcium salt-containing material with a cellulose derivative having a degree of substitution of carboxyalkyl groups up to about 0.65 wherein the cellulosic derivative contains cationic groups.
21. A filler obtainable by a method according to claims 19 or 20.
22. A process for the production of paper which comprises providing an aqueous suspension containing cellulosic fibres, introducing into the suspension a filler according to any one of claims 1-16 and 21, and dewatering the suspension to form a web or sheet of paper.
23. The process according to claim 22, characterised in that the filler is introduced into the suspension by adding a single composition containing the calcium salt and cellulose derivative to the suspension.
24. The process according to any one of claims 22 or 23, characterised in that the filler is added in an amount of from 5 to 30 % by weight, based on dry fibre.
25. The process according to claim 22 or 23, characterised in that it further comprises adding a cellulose-reactive sizing agent to the suspension.
