  • Patent number: 9580516
    Abstract: When a combination of pulps having different alkali metal hydroxide solution absorption rates is as a raw material, contact conditions such as a contact temperature and a contact time have to be changed frequently, depending on the absorption rate of pulps currently processed, thereby causing a problem of reduced productivity. For solving the problem, provided is a method for producing alkali cellulose, comprising at least the steps of: bringing two or more types of pulps having different alkali metal hydroxide solution absorption rates into contact with an alkali metal hydroxide solution to obtain a contact product; and draining the contact product, wherein the highest absorption rate is not more than 4.0 times as fast as the lowest absorption rate.
