Abstract
The present invention relates to a method of treating cellulose fibres. The invention further involves the production of paper from said treated fibres and the paper obtainable therefrom. The invention also relates to the use of a cellulose derivative as an additive to an acidic bleaching stage.
Claims (14)
1. Method of modifying cellulose fibres comprising providing a pulp suspension of cellulose fibres, adding a cellulose derivative during the bleaching of said cellulose fibres to at least one acidic bleaching stage.
2. Method according to claim 1, wherein the cellulose derivative is added to a final acidic bleaching stage.
3. Method according to any of claims 1-2, wherein the cellulose derivative is a carboxyalkyl cellulose.
4. Method according to any of claims 1-3, wherein the cellulose derivative is carboxymethyl cellulose.
5. Method according to any of claims 1-4, wherein the final acidic bleaching stage is a chlorine dioxide stage.
6. Method according to any of claims 1-5, wherein the cellulose derivative is added in an amount from about 0.5 to about 50 kg/t dry cellulose fibres.
7. Method according to any of claims 1-6, wherein the dry content of the cellulose fibres in the suspension is from about 1 to about 50 wt%.
8. Method according to any of claims 1-7, wherein a wet strength agent is subsequently added to a bleached pulp suspension.
9. Method according to any of claims 1-8, wherein a dry strength agent is subsequently added to a bleached pulp suspension.
10. Method according to any of the claims 1-9, wherein the final bleaching stage is performed at a pH from about 2 to about 4.
11. Method of producing paper comprising providing a suspension of bleached pulp according to any of claims 1-10, dewatering said pulp suspension on a wire and forming a paper of said dewatered pulp suspension.
12. Paper obtainable by the method according to claim 11.
13. Use of a cellulose derivative as an additive to a suspension of cellulose fibres being treated in an acidic bleaching stage.
14. Use of a cellulose derivative according to claim 13, wherein the bleaching stage is an acidic chlorine dioxide stage.
