Method of manufacturing a soft, bulky single-ply absorbent paper having a serpentine configuration

A process for the manufacture of a soft, single-ply absorbent paper product having a basis weight of at least about 12.5 lbs./3000 square foot ream which process comprises:

• providing a moving foraminous support;
• providing a headbox adjacent said moving foraminous support adapted to form a nascent web by depositing furnish upon said moving foraminous support wherein the cellulosic fibers into the furnish comprise:
• (a) at least about 20% by weight of the fibers in the web have a coarseness exceeding 23 mg/100 m;
• (b) at least about 20% by weight of the fibers in the web have a coarseness of less than about 12 mg/100 m;
• (c) the weight average coarseness to length ratio of the fibers in the web is less than about 8.5 mg/100 m/mm;
• and
• providing wet pressing means operatively connected to said moving foraminous support to receive said nascent web and for dewatering of said nascent web by overall compaction thereof;
• providing a Yankee dryer operatively connected to said wet pressing means and adopted to receive and dry the dewatered nascent web;
• supplying a furnish to said headbox comprising cellulosic papermaking fiber chosen from the group consisting hardwood, softwood, and recycled fibers, and cationic aldehyde-containing cationic temporary wet strength agents and nitrogenous softener/debonder;
• controlling the overall concentration of the aldehyde-containing cationic temporary wet strength agent and the cationic nitrogenous softener/debonder in said nascent web to between about 1 to about 20 lbs./ton on a dry fiber basis, the weight ratio of the wet strength agent to the softener debonder being controlled to be within the range of about 0.5 to about 10.0;
• wet pressing said nascent web;
• transferring said nascent web to said Yankee dryer, adhering said web to said Yankee, and creping said web from said Yankee;
• recovering a creped, dried, absorbent, single-ply paper product having a Yankee side and an air side;
• and
• printing such absorbent paper product on the Yankee side, the air side or both sides and recovering a printed, single-ply, absorbent paper product;
• controlling the relative amounts of the temporary wet strength agent and the nitrogenous softener/debonder such that said printed, single-ply, absorbent paper product exhibits:
• a specific total tensile strength of between 40 and 200 grams per 3 inches per pound per 3000 square foot ream, a cross direction specific wet tensile strength of between 2.75 and 20.0 grams per 3 inches per pound per 3000 square foot ream, the ratio of MD tensile to CD tensile of between 1.25 and 2.75, a specific geometric mean tensile stiffness of between 0.5 and 3.2 grams per inch per percent strain per pound per 3000 square foot ream, a friction deviation of less than 0.250, and a sidedness parameter of less than 0.30.
