Abstract:
A method of making a fabric-creped absorbent cellulosic sheet. The method includes compactively dewatering a papermaking furnish to form a web, creping the web under pressure in a creping nip between a transfer surface and a structuring fabric, the structuring fabric including knuckles formed on warp yarns of the structuring fabric, with the knuckles being positioned along lines that are angled relative to the machine direction of the fabric. The angle of lines relative to the machine direction is between about 10° and about 30°. The method also includes drying the web to form the absorbent cellulosic sheet.
