    摘要: A fibrous material is bleached by hydrogen peroxide in a weakly acidic state at a pH of 5-7, and then in a weakly alkaline state at a pH of 8.5-1.1 by adding an alkaline agent to the hydrogen peroxide by one whole charge or continuously after the bleaching in the weakly acidic state and utilizing the remaining hydrogen peroxide. The bleached fibrous material has a soft handling and a high whiteness, and no bleaching unevenness.

    摘要: In a loading and unloading apparatus, a plurality of guide rails are disposed as directed in the horizontal direction on a front surface of a support plate for a main body of the loading and unloading apparatus, which support plate has a fork at its bottom portion, base portions of a pair of arms which can be arbitrarily opened and closed in the directions of coming close to and separating from each other for clamping and releasing an object, are movably supported by these guide rails, and at the tip end portions of the respective arms are provided hooks which can be arbitrarily moved in the back and forth directions of the arms.
