Publication number: 20110011545Abstract: An absorbent cellulosic sheet having variable local basis weight includes a papermaking-fiber reticulum provided with (i) a plurality of cross-machine direction (CD) extending, fiber-enriched pileated regions of relatively high local basis weight interconnected by (ii) a plurality of elongated densified regions of compressed papermaking fibers. The elongated densified regions have relatively low local basis weight and are generally oriented along the machine direction (MD) of the sheet and have an MD/CD aspect ratio of at least 1.5. The products are most preferably prepared by way of a compactive dewatering/wet crepe process.Type: ApplicationFiled: September 23, 2010Publication date: January 20, 2011Inventors: Steven L.

Publication number: 20100314059Abstract: The present invention is a method of making a near-premium quality paper product having good strength and absorbency characteristics and a product made by that method. The invention is also a method for retaining a high ash content within a paper web formed by conventional wet pressing. The present invention is also a method for retaining a high percentage of softening agent within a paper web that includes such an agent. Further, the present invention is a soft absorbent paper product having a high void volume. Finally, the invention is also a method for producing a soft, absorbent, and near premium paper product having a high void volume using an undulatory crepe blade having a multiplicity of serrulations in its rake surface which presents differentiated creping angles and/or rake angles as to the paper being creped.Type: ApplicationFiled: August 17, 2010Publication date: December 16, 2010Applicant: Georgia-Pacific Consumer Products LPInventors: Steven L.
