| titleOfInvention | Dissolving pulp sheet |
| abstract | PROBLEM TO BE SOLVED: To provide a dissolving pulp sheet useful as a raw material for producing viscose rayon or a cellulose derivative, particularly a dissolving pulp sheet having excellent filterability of a viscose solution. SOLUTION: The dissolved pulp sheet is characterized in that the area of undissolved pieces of 1 mm or more and 10 mm or less in the dissolved pulp slurry prepared under the following conditions is 30% or less with respect to the total area of the dissolved pulp sheet. (The following: Dissolving pulp sheet cut into 1 cm squares is put into an aqueous solution of sodium hydroxide at 20 ° C. and a concentration of 18.2% so as to have a solid content concentration of 4%, and the pulp is dissolved by stirring at 500 rpm for 60 minutes. A pulp slurry is prepared, and after neutralization, undissociated pieces of 1 mm or more and 10 mm or less are collected, and the ratio of the total area of the undissociated pieces to the total area of the dissolved pulp sheet is calculated.)
