Abstract:
1. A method of making a belt-creped absorbent cellulosic sheet that has an upper surface and a lower surface, the method comprising: (a) compactively dewatering a papermaking furnish to form a dewatered web having an apparently random distribution of papermaking fiber orientation; (b) applying the dewatered web having the apparently random distribution of papermaking fiber orientation to a translating transfer surface that is moving at a transfer surface speed; (c) belt-creping the web from the transfer surface utilizing a generally planar polymeric creping belt provided with a plurality of perforations through the creping belt, the belt-creping step occurring under pressure in a belt creping nip defined between the transfer surface and the creping belt, wherein the creping belt is traveling at a belt speed that is slower than the transfer surface speed, and the web is creped from the transfer surface and redistributed on the creping belt to form a web comprising: (d) drying the web to produce the belt-creped absorbent cellulosic sheet.
