  • Papermaking process employing carboxylated cellulosic fibers
    Patent number: 8968518
    Abstract: A papermaking process includes, firstly, providing carboxylated cellulosic fibers with a carboxyl group content being in the range from 0.06 to 1.5 mmol/g. Then the carboxylated cellulosic fibers are employed to prepare mixing pulp including filler particles, wherein the content of the carboxylated cellulosic fibers in the mixing pulp is in the range from 40% to 100% by dry fiber weight of the mixing pulp. After that, paper is made employing the mixing pulp.

  • PROCESS FOR MAKING PULP
    Publication number: 20140305603
    Abstract: A process for making pulp includes providing plant fiber raw material. The plant fiber raw material can be wood fiber or gramineae plant fiber. The plat fiber raw material is cooked to make a pulp. A TEMPO catalytic oxidation system is added to the pulp to oxidize the pulp fiber. The oxidized pulp fiber is then bleached.
