Abstract:
A method of making a fibrous sheet includes providing a first furnish including a primary pulp having papermaking fibers, the papermaking fibers (i) having a weight-weighted average fiber length between about two and seven tenths millimeters and about three millimeters, (ii) a coarseness of about sixteen milligrams per one hundred meters or lower, and (iii) being at least eighty percent of the papermaking fibers of the first furnish, forming a nascent web having at least two layers, one of the at least two layers being (i) a surface layer of the nascent web and (ii) formed from the first furnish, dewatering the nascent web to form a dewatered web, applying the surface layer of the dewatered web to the outer surface of a Yankee drum of a Yankee dryer, and drying the dewatered web with the Yankee dryer to form a fibrous sheet.
