Method for the production of fiber pulp

Abstract

In a method for the production of fiber pulp for subsequent use in the production of a fiber web, especially a paper or cardboard web, the fiber pulp that was produced in a pulp production process is first loaded with an additive by way of a chemical precipitation reaction. The loaded pulp is then dried and available for subsequent utilization or formulated into a suitable form for shipment.

What is claimed is:  
     
         1 . A method for the production of pulp for subsequent use in the production of a fiber web, including the steps of: 
 loading the pulp with an additive by way of a chemical precipitation reaction; and    drying the pulp for at least one of a subsequent utilization and a formulation for shipment.    
     
     
         2 . The method of  claim 1 , further including the step of bleaching the pulp.  
     
     
         3 . The method of  claim 2 , wherein the pulp is subjected to at least one bleaching agent.  
     
     
         4 . The method of  claim 3 , wherein said at least one bleaching agent is at least one of a peroxide, a chlorine, an oxygen and an ozone.  
     
     
         5 . The method of  claim 4 , wherein said bleaching step includes a plurality of stages, at least one said stage including said at least one bleaching agent.  
     
     
         6 . The method of  claim 1 , wherein the pulp after said drying step possesses a dry content greater than 80%.  
     
     
         7 . The method of  claim 6 , wherein said dry content is greater than 85%.  
     
     
         8 . The method of  claim 6 , wherein said dry content is greater than 90%.  
     
     
         9 . The method of  claim 6 , wherein said dry content is greater than 95%.  
     
     
         10 . The method of  claim 1 , further including a step of refining the pulp after said loading step.  
     
     
         11 . The method of  claim 1 , wherein the pulp is loaded with a precipitated calcium carbonate.  
     
     
         12 . The method of  claim 1 , further including the step of cooking at least one natural fiber.  
     
     
         13 . The method of  claim 1 , wherein the pulp is supplied in a form of at least one of bales and rolls for at least one of said subsequent utilization and said formulation for shipment.  
     
     
         14 . The method of  claim 1 , wherein the pulp is produced according to at least one of a sulfate process and a sulfite process.  
     
     
         15 . The method of  claim 1 , wherein said fiber web is at least one of a paper web and a cardboard web.
