    摘要： There is provided a fiber body manufacturing method including an accumulating step of forming the web by accumulating a material containing fibers and starch or dextrin on the first transport belt by a dry method; a transport step of transporting the web by peeling off a first surface of the web from the first transport belt, and by bringing a second surface of the web, which is a surface opposite to the first surface peeled off from the first transport belt, into contact with the second transport belt; a water-applying step of applying the water to the web which is in contact with the first transport belt or the second transport belt; and a heating step of heating the web by bringing the heating section into contact with the web peeled off from the second transport belt, and forming a fiber body by binding the fibers with the starch or dextrin, in which the web peeled off from the second transport belt is directly supplied to the heating section.

    摘要： A method to produce dried single-layer or multi-layer paper is disclosed. The method comprises, for a single-layer paper, preparing and spraying a partially dehydrated first fibrous web with a spray solution or suspension to give a sprayed partially dehydrated first fibrous web, and dehydrating the sprayed partially dehydrated first fibrous web by applying heat to form a dried single-layer paper; or, for a multi-layer paper, preparing and spraying a partially dehydrated layer compound with a spray solution or suspension to form a sprayed layer compound, and dehydrating the sprayed layer compound by applying heat to form a dried multi-layer paper. The spray solution or suspension comprises water and at least one water-soluble polymer P, which is obtained by polymerizing: (i) a monomer of formula H2CCHNHC(0)R1, where R1 is H or C1-C6- alkyl; and (ii) one or more ethylenically unsaturated monomers different from monomer (i).
