SOFT ABSORBENT SHEETS, STRUCTURING FABRICS FOR MAKING SOFT ABSORBENT SHEETS, AND METHODS OF MAKING SOFT ABSORBENT SHEETS

摘要

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.

主权项

1. An absorbent cellulosic sheet comprising:
a plurality of projected regions projecting from the absorbent sheet, wherein the projected regions are formed in 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 such that one of the ends of each of the curved folds is positioned downstream from the other end of the curved folds in the machine direction of the absorbent sheet, and with apexes of the curved folds being positioned downstream in the machine direction of the absorbent sheet; and connecting regions connecting the projected regions of the absorbent sheet.
