Abstract

The present invention relates to a filler comprising clay and cellulose derivative having a degree of substitution of net ionic groups up to about 0.65. The invention also relates to a filler comprising clay and a cellulose derivative having a degree of substitution of carboxyalkyl groups up to about 0.65. The invention further relates to a method of producing a filler which comprises mixing clay with a cellulose derivative having a degree of substitution of net ionic groups up to about 0.65. The invention also relates to a method of producing a filler which comprises mixing clay with a cellulose derivative having a degree of substitution of carboxyalkyl groups up to about 0.65. 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 clay and cellulose derivative having a degree of substitution of net ionic groups up to about 0.65, 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 clay and cellulose derivative having a degree of substitution of carboxyalkyl groups up to about 0.65, and dewatering the suspension to form a web or sheet of paper.

Claims (19)

13. The process according to any one of claims 1 and 4 to 12, the filler according to any one of claims 2, 4 to 8 and 10 to 12, or the method according to any one of claims 3 to 8 and 10 to 12, characterised in that the filler has a clay content from 60 to about 80 % by weight, based on the weight of the solids of the filler.
14. The process according to any one of claims 1 and 4 to 13, the filler according to any one of claims 2, 4 to 8 and 10 to 13, or the method according to any one of claims 3 to 8 and 10 to 13, characterised in that the clay is a kaolin clay.
15. The process according to any one of claims 1 and 4 to 14, the filler according to any one of claims 2, 4 to 8 and 10 to 14, or the method according to any one of claims 3 to 8 and 10 to 14, characterised in that the clay is calcinated clay.
16. The process according to any one of claims 1 and 4 to 15, the filler according to any one of claims 2, 4 to 8 and 10 to 15, or the method according to any one of claims 3 to 8 and 10 to 15, characterised in that the clay is talc.
17. Paper comprising a filler according to any one of claims 2, 4 to 8 and 10 to 16.
18 18. The paper according to claim 16, characterised in that the total filler content of the paper is from 5 to 40 % by weight, based on dry paper.
19. The process according to any one of claims 1 and 4 to 16, characterised in that the filler is added in an amount of from 5 to 30 % by weight, based on dry fibre.
