    摘要： A method of making a belt-creped absorbent cellulosic sheet. A paper making furnish is compactively dewatered to form a dewatered web having an apparently random distribution of papermaking fiber orientation. The dewatered web is applied to a translating transfer surface that is moving at a transfer surface speed. The web is belt-creped from the transfer surface at a consistency of from about 30% to about 60% utilizing a generally planar polymeric creping belt having a plurality of perforations, under pressure, in a belt creping nip defined between the transfer surface and the creping belt. The belt travels at a belt speed that is slower than the speed of the transfer surface. The web is creped from the transfer surface and redistributed on the creping belt to form a web having a plurality of interconnected regions of different local basis weights. The web is then dried.

    摘要： A method of making a fabric-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a nascent web. The nascent web is applied to a translating transfer surface and is fabric-creped from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric. The creping fabric travels at a fabric speed that is slower than the speed of the transfer surface. The nascent web is creped from the transfer surface and redistributed on the creping fabric to form a creped web with a drawable reticulum having a plurality of interconnected regions of different local basis weights. The creped web is dried to form a dried web, and the dried web is drawn. The drawing step includes drawing the dried web between a first draw roll and a second draw roll.

    摘要： A forming fabric for use in papermaking machines for making tissue products in which the fabric is a three-ply fabric. The upper ply has its machine direction (MD) filaments arranged in groups so that wide channels are provided through the ply between the groups and narrow channels are provided through the ply within the groups. Cross direction (CD) filaments in the upper ply provide CD knuckles spanning across the channels to provide a gridwork for supporting fibers separated from the water of the slurry deposited on the forming fabric, the fibers having a greater density in bands overlying the wide channels than in the intermediate bands overlying the narrow channels. The lower ply is a porous fabric which further controls the flow of the water discharged from the pulp through the upper ply. The two plies are interconnected by integrated binder filaments which cooperate to maintain the groupings of the MD filaments in the upper ply. The predominant CD knuckles on the paper side of the fabric provide topographic lines crossing the MD channels diagonally in both directions.
