The present invention aims to provide cellulose-based fibrous materials for obtaining papers and sheets having low density, high surface quality, good size stability despite of high strength, and high opacity. Cellulose-based fibrous materials having external fibrils consisting of an assembly of scale-like microfibrils exhibit a higher fiber stiffness, a lower water retention value and a higher specific surface area as compared with fibrous materials having filamentous external fibrils at the same freeness. Papers and sheets having low density, high surface quality, good size stability and high opacity can be obtained by using such fibrous materials.

InactiveCN1421570AWell mixedChemical/chemomechanical pulpNon-woody plant/crop pulpLignin peroxidaseXylanase Y
The enzymatic straw material pulping process includes three stages of mechanical pre-treatment, enzyme treatment and chemical pulping or chemical-mechanical pulping. After being pretreated mechanically in a pulp grinder, the straw material is treated with hemicellulase liquid or mixed enzyme liquid comprising hemicellulase and lignin peroxidase at pH 3.5-6.5 and 40-60 deg.c for 1-10 hr. In chemical pulping, the material is presoaked with waste pulp-making liquor before extruding out wastes liquor and digested; and in chemical-mechanical pulping, the material is first treated with EDTA, NaOH and H2O2 at 40-80 deg.c for 30-120 min and then ground to form the pulp. The present invention is used in papermaking enterprises with straw as material and has the advantages of low pollution load, high, paper pulp quality, easy-to-process waste liquor, etc.

It also discloses a method of wood pulping having a significantly increased yield and providing fiber pulps with enhanced properties such as strength and stiffness. Wood chips are chemically pulped to a high kappa number, providing a rejects component and an accepts component. The rejects component is subjected to a substantially mechanical pulping process, optionally in a presence of bleaching agent, prior to blending back into the accepts component. The resulting fiber blend is washed, optionally bleached, and subjected to a papermaking process to provide paper or paperboard with enhanced strength and stiffness at low basis weight.
