Abstract
Soft absorbent sheets, structuring fabrics for producing soft absorbent sheets, and methods of making soft absorbent sheets. The soft absorbent sheets have a plurality of projected regions and connecting regions that connect the projected regions. The projected regions include folds that are curved relative to a machine direction of the absorbent sheet, with ends of the curved folds being on opposite sides of the projected regions, and with apexes of the curved folds being positioned downstream in the machine direction of the absorbent sheet. The absorbent sheets can be formed by structuring fabrics that have angled lines of warp yarn knuckles.
