Abstract
There is provided a method of making absorbent sheet including the steps of: (a) an aqueous cellulosic furnish on a foraminous support; (b) at least partially dewatering the furnish to form a nascent web; (c) applying the nascent web to a rotating cylinder and drying the web to a consistency of from about 30 to about 90 percent solids; (d) creping the web at the consistency of from about 30 to about 90 percent while maintaining a narrow creping shelf effective width; and (e) drying the creped web to form an absorbent sheet, wherein the absorbent sheet exhibits a Void Volume of at least about 3.5 gms/gm. The process is advantageously applied to absorbent sheet having a thickness of from about 0.003 inches to about 0.010 inches while utilizing a creping blade having a creping surface with a ledge width of from about 0.005 inches to about 0.025 inches.
