Abstract:
      The pulping of the mixture of non-wood materials and hardwoods was investigated in the paper.Three non-wood materials,miscanthus,switchgrass and corn stover were partially substituted for poplar wood chips and the mixture was subjected to typical kraft pulping experiments.The pulp was then bleached with an OD(EP)D sequence.The bleached pulp was refined and formed into handsheets to characterize their physical properties.The results showed that all pulps produced from the mixture raw materials had improved strength properties compared with the poplar pulp.Carbohydrate analysis of the pulps indicated that the strength increase was correlated with enriched xylan content in the pulp.Based on these results,cooking of hardwood mixing certain amount of non-wood materials contained high xylan content could produce high quality pulp.
