Abstract
Rolled creped paper products, such as kitchen towels, can be provided with high roll bulk and a high degree of roll firmness by steaming the dry, creped paper sheet immediately prior to embossing the sheet between matched steel embossing rolls. The steaming preconditions the sheet such that the resulting sheet embossments maintain their shape and structural strength, thereby imparting greater bulk and firmness to the wound roll of product. In addition, the sheet experiences less cross-machine strength reduction as a consequence of the embossing.

A roll of single-ply creped paper having a roll bulk of 13 cubic centimeters per gram (cc/g) or greater, a roll firmness of 10 millimeters (mm) or less and a cross-machine direction (CD) tensile strength of about 2000 or greater grams per 3 inches of width (grams).
A roll of creped paper having a roll bulk of 13 cubic centimeters per gram (cc/g) or greater, a roll firmness of from about 6 to about 7.7 millimeters and a cross-machine direction (CD) tensile strength of about 2000 or greater grams per 3 inches of width (grams).
