Abstract

Cellulose pulp sheets treated with a saccharide yield less than 20 wt. % knots when fiberized under standard Kamas conditions. The fiberized sheets when airlaid produce fiber webs that exhibit desirable densification properties and softness properties.

Claims

exact text as granted — not AI-modified
1 . A cellulose pulp sheet comprising: 
 cellulose fibers; and    a saccharide, wherein the pulp sheet when fiberized under standard Kamas conditions yields less than 20 wt. % knots.    
     
     
         2 . The cellulose pulp sheet of  claim 1  having a density greater than about 0.3 g/cm 3 .  
     
     
         3 . The cellulose pulp sheet of  claim 1 , wherein the cellulose fibers are wood pulp fibers.  
     
     
         4 . The cellulose pulp sheet of  claim 1 , wherein the saccharide is a corn syrup.  
     
     
         5 . The cellulose pulp sheet of  claim 4 , wherein the corn syrup is applied at a solids content less than about 65 wt. %.  
     
     
         6 . The cellulose pulp sheet of  claim 4 , wherein the corn syrup includes solids that are present in an amount less than 10 wt. % based on the weight of dry cellulose fiber in the cellulose pulp sheet.  
     
     
         7 . The cellulose pulp sheet of  claim 1 , wherein the saccharide is a high fructose corn syrup.  
     
     
         8 . The cellulose pulp sheet of  claim 7 , wherein the high fructose corn syrup is applied at a solids content less than about 65 wt. %.  
     
     
         9 . The cellulose pulp sheet of  claim 7 , wherein the high fructose corn syrup includes high fructose corn syrup solids that are present in an amount less than about 10 wt. % based on the weight of dry cellulose fiber in the cellulose pulp sheet.  
     
     
         10 . A cellulose pulp sheet consisting essentially of: 
 cellulose fibers;    a corn syrup, wherein the pulp sheet when fiberized under standard Kamas conditions yields less than 20 wt. % knots.    
     
     
         11 . The cellulose pulp sheet of  claim 10  wherein the corn syrup is high fructose corn syrup.  
     
     
         12 . A method for producing a saccharide treated cellulose pulp sheet that when fiberized under standard Kamas conditions yields less than 20 wt. % knots comprising: 
 providing a cellulose pulp sheet; and    applying a saccharide to the cellulose pulp sheet.    
     
     
         13 . The method of  claim 12 , wherein the cellulose pulp sheet has a density greater than about 0.3 g/cm 3 .  
     
     
         14 . The method of  claim 12 , wherein the cellulose pulp sheet comprises wood pulp fibers.  
     
     
         15 . The method of  claim 12 , wherein the saccharide is a corn syrup.  
     
     
         16 . The method of  claim 15 , wherein the corn syrup has a solids content less than about 65 wt. %.  
     
     
         17 . The method of  claim 15 , wherein the corn syrup is applied to the cellulose pulp sheet so that the corn syrup solids content of the saccharide treated cellulose pulp sheet is less than 10 wt. % based on the dry weight of the cellulose fiber in the saccharide treated cellulose pulp sheet.  
     
     
         18 . The method of  claim 12 , wherein the saccharide is a high fructose corn syrup.  
     
     
         19 . The method of  claim 18 , wherein the high fructose corn syrup has a solids content less than about 65 wt. %.  
     
     
         20 . The method of  claim 18 , wherein the high fructose corn syrup is applied to the cellulose pulp sheet so that the high fructose corn syrup solids content of the saccharide treated cellulose pulp sheet is less than 10 wt. % based on the dry weight of the cellulose fibers in the saccharide treated cellulose pulp sheet.  
     
     
         21 . A cellulose pulp in non-sheet form comprising: 
 a mass of cellulose fibers, the mass having a density of at least 0.3 g/cm 3 ; and    a saccharide, wherein the cellulose pulp in non-sheet form, when fiberized under standard Kamas conditions yields less than 20 wt. % knots.    
     
     
         22 . An absorbent product comprising a fiberized cellulose pulp sheet of  claim 1  or  10 .  
     
     
         23 . An absorbent product comprising a fiberized cellulose pulp of  claim 21.
