Enzymatic paper and process of making thereof

Abstract

The present invention includes a process for making paper. The process may include the steps of providing pulp fibers in a chest and adding an enzymatic material to the pulp fibers at a storing stage for decreasing cellulose crystals. Furthermore, the process may include adding a strength agent to the pulp fibers at the storing stage.

         1 . A process for making paper comprising the step of adding an enzymatic material at a storing stage of a papermaking process to modify the pulp.  
     
     
         2 . The process of  claim 1  further comprising the step of: 
 adding a strength agent to pulp at the storing stage.  
 
     
     
         3 . The process of  claim 1  wherein the enzymatic material further comprises cellulase and hemicellulase.  
     
     
         4 . The process of  claim 1  wherein the enzymatic material further comprises an enzyme selected from the group consisting of endo-glucanase, cellubiohydrolase, cellubiase, xylanase, and hemicellulase.  
     
     
         5 . The process of  claim 1  wherein the enzymatic material further comprises endo-glucanase, cellubiohydrolase, cellubiase, xylanase, and hemicellulase.  
     
     
         6 . The process of  claim 2  wherein the strength agent further comprises a dry strength agent.  
     
     
         7 . The process of  claim 6  wherein the dry strength agent is selected from the group consisting of starch, polyacrylamide, guar, locust bean gums, and carboxymethyl cellulose.  
     
     
         8 . The process of  claim 2  wherein the strength agent further comprises a wet strength agent.  
     
     
         9 . The process of  claim 8  wherein the wet strength agent is selected from the group consisting of polyamide-epichlorohydrin, polyacrylamides, styrenebutadiene latexes, insolubilized polyvinyl alcohol, urea-formaldehyde, polyethyleneimine, and chitosan polymers.  
     
     
         10 . A paper made from pulp modified by an enzymatic material at a storing stage of a papermaking process.  
     
     
         11 . The paper of  claim 10  wherein the pulp is further modified by adding a strength agent to the pulp at the storing stage.  
     
     
         12 . The paper of  claim 10  wherein the enzymatic material further comprises cellulase and hemicellulase.  
     
     
         13 . The paper of  claim 10  wherein the enzymatic material further comprises an enzyme selected from the group consisting of endo-glucanase, cellubiohydrolase, cellubiase, xylanase, and hemicellulase.  
     
     
         13 . The paper pf  claim 10  wherein the enzymatic material further comprises ebdi-glucanase. cellubiohydrolase, cellubiase, xylanase, and hemicellulase.  
     
     
         14 . The paper of  claim 11  wherein the strength agent further comprises a dry strength agent.  
     
     
         15 . The paper of  claim 11  wherein the strength agent further comprises a wet strength agent.  
     
     
         16 . A paper prepared from a pulp modified with an enzymatic material and having a greater solids content after being formed on a forming fabric than a paper not modified with an enzymatic material.  
     
     
         17 . A paper prepared from a pulp modified with an enzymatic material and having faster drop absorbency compared to a paper not modified with an enzymatic material.  
     
     
         18 . The paper of  claim 17  prepared from a pulp modified with an enzymatic material wherein the paper has a higher permeability than a paper not modified with an enzymatic material.  
     
     
         19 . The paper of  claim 18  prepared from a pulp modified with an enzymatic material wherein the paper has a higher Z wicking than a paper not modified with an enzymatic material.  
     
     
         20 . The paper of  claim 19  prepared from a pulp modified with an enzymatic material wherein the paper has a greater water capacity than a paper not modified with an enzymatic material.
