摘要： The present invention is related to a water dispersible paper, particularly for use in packages in the construction area. The dispersibility of the paper of the present invention is achieved due to the low wet resistance and high capillary absorption and basically consists of an unbleached cellulose-based paper aiming at the reduction of ingredients conventionally used, adding only defoamers and drainage aids in the formulation thereof. The paper of the present invention consists in the elimination of the use of disintegration aids (such as surfactants), gluing agents and dry resistance agents (such as starch). There is further described a manufacturing process for dispersible paper which allows obtaining a paper having low wet tensile strength and high capillary rise without the need for the chemical agents usually known for the manufacture of this type of paper. The present invention further foresees a package containing said paper for use in construction such as in packages for, lime, sand, cellulosic or synthetic fibers or powder pigments, among others.

摘要： A tissue product with at least four plies made of tissue paper base sheet or nonwoven comprises:
a first outer ply and a second outer ply and at least two inner plies between the first outer ply and the second outer ply, wherein
only one of the inner plies is un-embossed;
the outer plies comprise a micro-embossing pattern;
at least one of the outer plies comprises a décor embossing pattern; and
at least two adjacent inner plies comprise the un-embossed inner ply and one micro-embossed inner ply; wherein the density of the micro-embossed protrusions of the micro-embossed inner ply is different to the density of further embossed protrusions of the micro-embossing pattern of the outer ply which is adjacent to the micro-embossed inner ply.-

摘要： A raw-material feeding device includes: a storage section that includes a bottom section and a side wall standing from the bottom section and that stores, in a storage space surrounded by the bottom section and the side wall, small pieces of raw material constituted by a material containing fibers; a stirring section that is provided in the bottom section at a position facing the storage space, that includes a blade which rotates about a rotational axis extending in a direction in which the side wall stands, and that stirs the raw material in the storage space by rotating the blade; a first discharging section that is provided in the side wall so as to communicate with the storage space, that includes a first tubular body rotating about a first axis intersecting the rotational axis, and that discharges, upon rotation of the first tubular body, the raw material in the storage space to a processing section; and a second discharging section that is provided in the side wall at a position different from a position at which the first tubular body is provided so as to communicate with the storage space, that includes a second tubular body rotating about a second axis intersecting the rotational axis, and that discharges, upon rotation the second tubular body, the raw material in the storage space to the processing section.
