  • Publication number: 20210032415
    Abstract: Provided is a method for producing cellulose particles or cellulose acetate particles. By a production method including: (a) dissolving cellulose acetate in an organic solvent and preparing a cellulose acetate solution; (b) obtaining an emulsion of the cellulose acetate solution and an aqueous medium using a porous membrane; and (c) precipitating cellulose acetate particles from the emulsion, cellulose acetate particles are produced. By further saponifying the cellulose acetate obtained by the production method, cellulose particles are produced.

  • Publication number: 20210032372
    Abstract: Provided is a method for producing cellulose particles or cellulose acetate particles. By a production method including: (a) dissolving cellulose acetate in an organic solvent and preparing a cellulose acetate solution; (b) obtaining an emulsion by passing the cellulose acetate solution and an aqueous medium through a gap between an outer cylinder and an inner cylinder arranged coaxially inside the outer cylinder and rotating at least one of the outer cylinder and the inner cylinder; and (c) precipitating cellulose acetate particles from the emulsion, cellulose acetate particles are produced. By further saponifying the cellulose acetate obtained by the production method, cellulose particles are produced.

  • Patent number: 7552917
    Abstract: A sheet processing apparatus includes: a buffer unit which stores plural supplied sheets with upstream edges in a conveying direction thereof aligned; a processing tray on which sheets discharged from the buffer unit are stacked; and an oscillation roller pair and a return roller which convey the sheet stacked on the processing tray to bring the sheet into abutment against a stopper for receiving the upstream edge of the sheet. The buffer unit is adapted to align the upstream edges of only sheets to be stored before a sheet to be supplied last among the sheets to be stored.
