A method for preparing modified pulp

Abstract

A method is disclosed. The method may comprise adding a hydrophobization agent to wet pulp; drying the wet pulp, thereby obtaining dried pulp; wherein the dried pulp is intended for defibrillating into fibers, thereby obtaining the modified pulp; or the method further comprises defibrillating the dried pulp into fibers, thereby obtaining the modified pulp.

1 . A method for preparing modified pulp, wherein the method comprises adding a hydrophobization agent to wet pulp;
 drying the wet pulp, thereby obtaining dried pulp;   wherein the dried pulp is intended for defibrillating into fibers, thereby obtaining the modified pulp; or the method further comprises defibrillating the dried pulp into fibers, thereby obtaining the modified pulp.   
     
     
         2 . A method for preparing modified pulp, wherein the method comprises defibrillating dried pulp, thereby obtaining the modified pulp; wherein the dried pulp is obtainable by adding a hydrophobization agent to wet pulp and by drying the wet pulp. 
     
     
         3 . The method according to  claim 1 , wherein the modified pulp is modified defibrillated pulp or modified fluff pulp, and/or the dried pulp is dried fluff pulp. 
     
     
         4 . The method according to  claim 1 , wherein the pulp is defibrillated by shredding. 
     
     
         5 . The method according to  claim 1 , wherein the hydrophobization agent comprises or is a resin, wax, a wet glue resin, or any mixture or combination thereof. 
     
     
         6 . The method according to  claim 1 , wherein the hydrophobization agent is added to a wet pulp with a pH in the range of 2 to 6. 
     
     
         7 . The method according to  claim 1 , wherein the method is a method for producing an article, and the method further comprises forming an article of the modified pulp. 
     
     
         8 . Modified pulp, wherein the modified pulp is defibrillated and exhibits an absorption time of at least 20 seconds. 
     
     
         9 . Modified pulp prepared by the method according to  claim 1 , wherein the modified pulp is defibrillated and exhibits an absorption time of at least 20 seconds. 
     
     
         10 . The modified pulp according to  claim 8 , wherein the absorption capacity of the modified pulp is in the range of 7-12 g/g. 
     
     
         11 . The modified pulp according to  claim 8 , wherein the modified pulp is modified defibrillated pulp and/or modified fluff pulp. 
     
     
         12 . An article obtainable from or formed of the modified pulp according to  claim 8 . 
     
     
         13 . The article according to  claim 12 , wherein the article is a single use article or a single use item. 
     
     
         14 . A method for producing an article, the method comprising forming the article of the modified pulp according to  claim 8 . 
     
     
         15 . The method according to  claim 14 , wherein the article is a single use article or a single use item. 
     
     
         16 . The article of  claim 12 , wherein the article is form pressed. 
     
     
         17 . The article of  claim 13 , wherein the article is a container, a catering item, a casing, a tray, a cup, cutlery, a utensil, a plate, or a packaging article; a filter; or an insulator 
     
     
         18 . The method according to  claim 7 , wherein forming the article of the modified pulp comprises form pressing.
