Abstract
A method of making a fabric-creped absorbent cellulosic sheet with improved dispensing characteristics. The method includes compactively dewatering a papermaking furnish to form a nascent web, applying the nascent web to a translating transfer surface, fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a patterned creping fabric, the fabric-creping step occurring under pressure in a fabric creping nip defined between the transfer surface and the creping fabric, wherein the fabric is traveling at a fabric speed that is slower than the speed of the transfer surface, the web being creped from the transfer surface and transferred to the creping fabric, adhering the web to a drying cylinder with a resinous adhesive coating composition, drying the web on the drying cylinder to form a dried web, and peeling the dried web from the drying cylinder.
