| titleOfInvention | Method for producing sulfonated fine cellulose fiber and method for producing sulfonated pulp fiber |
| abstract | The present invention provides a method for producing a sulfonated pulp fiber excellent in handleability and a method for producing a sulfonated fine cellulose fiber excellent in transparency. A method for producing a pulp fiber in which a part of a hydroxyl group of cellulose is sulfonated from a pulp includes a chemical treatment step for chemically treating the pulp, and the chemical treatment step constitutes the pulp. A contact step of bringing a sulfonating agent having a sulfo group into contact with the pulp fiber and urea or / and a derivative thereof; a reaction step of introducing a sulfo group into a part of the hydroxyl groups of cellulose constituting the pulp fiber after the contact step; Therefore, a sulfonated pulp fiber excellent in handleability can be produced.
