    摘要： The present invention aims to provide cellulose-based fibrous materials for obtaining papers and sheets having low density, high surface quality, good dimensional 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 dimensional stability and high opacity can be obtained by using such fibrous materials.

    摘要： The first invention aims to provide a method for preparing stiffer bulky pulp at a freeness level comparable to that obtained by mechanical treatments to improve the bulkiness of product paper by searching for a method capable of adjusting freeness while suppressing damage to pulp fibers and internal fibrillation in a process for producing pulp. The second invention aims to strip contaminants deposited on pulp fibers and/or inorganic particles to reduce adhesion of the contaminants and decrease microorganisms in a treatment of process water containing long pulp fiber fractions used in a process for producing pulp and paper, thereby clarifying process water and thus preparing high-quality pulp and paper. According to the first invention, cavitation is generated in a pulp suspension preferably by a liquid jet and the resulting fine bubbles are introduced into the pulp suspension to adjust the pulp suspension to a desired freeness by means of the impact force induced by collapse of the fine bubbles in a process for producing pulp. According to the second invention, process water containing 50% by weight or less, based on total solids, of long pulp fiber fractions used in a process for producing pulp and/or paper is treated by cavitation generated by a liquid jet and then returned to the process for producing pulp and/or paper and reused.

    摘要： Object to attain:
    To offer a papermaking raw material processor capable of reforming pulp in papermaking process, thanks to cavitation.
    Means to solve the problem:
    First pump 5 jets jet liquid and second pump 6 jets suspension containing e.g. pulp fibers into a processing unit inside which cavitation is generated by generation of a jet stream. Inside processing unit 2, a jet stream generates cavitation to carry out a reforming processing in which ink or the like is removed from the fibers by a blast resulting from collapse of cavitation bubbles generated there. The liquid after reforming processing is returned to second tank 4, except for a part of it fed to downstream steps, while the suspension is processed, as circulated between processing unit 2 and second tank 6.
