Soft single-ply tissue having very low sideness

A process for the manufacture of a soft bathroom tissue product having a serpentine configuration and a low sidedness, which process comprises:

• providing a moving foraminous support;
• providing a stratified headbox adjacent said moving foraminous support adapted to form a nascent web by depositing furnish upon said moving foraminous support, said stratified headbox having at least two plena;
• 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 moving foraminous support and said wet pressing means and adapted to receive and dry the dewatered nascent web;
• one plenum of said headbox being adapted to deposit a Yankee-side stratum of furnish on said moving foraminous support such that, during drying of said nascent web, said Yankee-side stratum will engage said Yankee;
• another plenum of said headbox being adapted to deposit a distal stratum of furnish on said moving foraminous support such that, during drying of said nascent web, said distal stratum will be spaced from said Yankee;
• supplying a furnish to said one plenum comprising:
• cellulosic papermaking fiber chosen from the group consisting of hardwood, softwood, and recycled fibers, and cationic nitrogenous softener/debonder;
• supplying another furnish to said other plenum comprising:
• cellulosic papermaking fiber chosen from the group consisting of hardwood, softwood, and recycled fibers, and cationic nitrogenous softener/debonder;
• forming a nascent web by depositing said one furnish and said other furnish on said moving foraminous support, the overall concentration of cationic nitrogenous softener/debonder in said nascent web being controlled to between about 1 to about 8 lbs/ton on a dry fiber basis;
• the concentration of cationic nitrogenous softener/debonder in said Yankee-side stratum to from about 2% to no more than 75% of the concentration of said cationic nitrogenous softener/debonder in the distal stratum;
• 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 bathroom tissue product;
• and
• forming a roll of single-ply tissue;
• controlling the relative amounts of softwood fibers, recycle fibers, hardwood fibers, and cationic nitrogenous softener/debonder in each of said strata wherein said tissue comprising at least two differentiated strata which do not delaminate from each other such that said creped, dried tissue exhibits:
• a sidedness parameter of less than 0.3, a tensile modulus of no more than 32 grams/percent strain, a GM MMD friction of no more than about 0.225, and a cross directional dry tensile strength of at least 200 grams per 3 inches.
