APMP PULPS FROM NONWOOD FIBER PART 1: KENAF AND STRAW

摘要

Results from the present investigation have demonstrated that using alkaline peroxide pretreatment followed by refiner mechanical pulping, both kenaf and straw fibers may be converted into pulps having strength properties comparable to aspen APMP. Kenaf fiber was relatively easy to bleach, and has potentials for applications similar to aspen APMP or market BCTMP, which is currently used in printing/writing, tissue and high bright paperboard grades. Compared to kenaf, straw was more difficult to bleach. Because of this, application potential of straw APMP pulp may be limited to low brightness grades such as newsprint and low brightness paperboard.
