Method for Producing Paper, Paperboard and Cardboard in the Presence of Water-Swellable Polymers

Abstract

A process for the production of paper, board and cardboard in the presence of a water-swellable polymer by adding the water-swellable polymer to a fiber suspension, the fiber suspension comprising water-swellable polymers being beaten.

1 . A process for the production of paper, board and cardboard in the presence of water-swellable polymers by adding the water-swellable polymer to a fiber suspension, wherein the fiber suspension comprising water-swellable polymers is beaten. 
     
     
         2 . The process according to  claim 1 , wherein the water-swellable polymer can absorb at least 1% of its own weight of water. 
     
     
         3 . The process according to  claim 1 , wherein the water-swellable polymers are superabsorbent polymers. 
     
     
         4 . The process according to  claim 1 , wherein paper process chemicals are added after the beating of the fiber suspension comprising water-swellable polymers. 
     
     
         5 . The process according to  claim 1 , wherein the water-swellable polymer is added as a gelatinous suspension to the fiber suspension. 
     
     
         6 . The process according to  claim 1 , wherein the water-swellable polymer is introduced into the fiber suspension by spraying. 
     
     
         7 . The process according to  claim 1 , wherein from 0.1 to 20% by weight of a water-swellable polymer are added to the fiber suspension. 
     
     
         8 . (canceled) 
     
     
         9 . A paper, board or cardboard produced by the process according to  claim 1 . 
     
     
         10 . The paper according to  claim 9 , characterized in that it is tissue paper, hygiene or sanitary paper, packaging paper or multilayer paper.
