Abstract:
To provide a method for producing pulp, by which all cellulose waste fiber materials can be used without needing a complicated chemical reaction operation such as the dissolution of the cellulose waste fiber material and without limiting the employment of the cellulose waste fiber materials due to color classification and dye kind classification.
This method for producing the pulp comprises immersing a cellulose waste fiber material in an alkali metal hydroxide solution and then crushing the waste fiber material in a state containing the alkali metal hydroxide solution. The paper is produced from the pulp, while using the pulp as at least one part of paper-producing materials.
