Hydrophilic, humectant, soft, pliable, absorbent paper having wet strength agents and method for its manufacture

A process for the manufacture of a hydrophilic, humectant, soft, pliant single-ply or multi-ply absorbent napkin which process comprises:

• providing a moving foraminous support,
• providing a headbox;
• forming a nascent web by depositing furnish upon said foraminous support;
• providing partly through air drying means operatively connected to said moving foraminous support to receive said nascent web and for dewatering of said nascent web and partly through air drying the wet web and providing a Yankee dryer operatively connected to said wet pressing means and said air drying means and adapted to receive and dry the partially dried nascent web;
• supplying a furnish to said headbox comprising:
• cellulosic papermaking fiber consisting essentially of recycle fiber, hardwood fiber, softwood fiber, and mixtures thereof, and up to 50% synthetic fiber, and adding a softener having a melting range of 0-40° C. wherein the softener comprises an imidazoline moiety formulated with organic compounds having a weight average molecular weight of about 60 to 1500 selected from the group consisting of alkoxylated aliphatic polyols, alkoxylated aliphatic diols, aliphatic polyols, aliphatic diols and a mixture of these wherein the amount of softener added is about 1 to 10 pounds per ton of furnish but within these parameters the addition of the softener is controlled to achieve a ratio of average particle size of dispersed softener to average fiber diameter in the range of about 0.01 to about 15 percent;
• forming a nascent web by depositing said furnish on said moving foraminous support adding an organic permanent wet strength agent or a temporary wet strength agent, the amount of wet strength agent added per ton of furnish is about 1 to 20 pounds, provided that the wet strength agent having no charge is sprayed during or after drying while the wet strength agent having a charge is added during the wet end paper making process;
• partially through air drying the web;
• transferring said nascent web to said Yankee dryer, adhering said web to said Yankee dryer, creping said web from said Yankee dryer;
• recovering a creped, dried absorbent napkin having a serpentine configuration.

A process for the manufacture of a hydrophilic, humectant, soft, pliant single ply or multi ply absorbent bathroom tissue which process comprises:

• providing a moving foraminous support,
• providing a headbox;
• forming a nascent web by depositing furnish upon said foraminous support;
• providing partially through air drying means operatively connected to said moving foraminous support to receive said nascent web and for dewatering of said nascent web and partly through air drying the wet web and providing a Yankee dryer operatively connected to said wet pressing means and said air drying means and adapted to receive and dry the partially dried nascent web;
• supplying a furnish to said headbox comprising:
• cellulosic papermaking fiber consisting essentially of recycle fiber, hardwood fiber, softwood fiber, and mixtures thereof, and up to 50% synthetic fiber, and adding a softener having a melting range of about 0°-40° C. wherein the softener comprises an imidazoline moiety formulated with organic compounds having a weight average molecular weight of about 60 to 1500 selected from the group consisting of alkoxylated aliphatic polyols, alkoxylated aliphatic diols, aliphatic polyols, aliphatic diols and a mixture of these wherein the amount of softener added is about 1 to 10 pounds per ton of furnish but within these parameters the addition of the softener is controlled to achieve a ratio of average particle size of dispersed softener to average fiber diameter in the range of about 0.01 to 15 percent;
• forming a nascent web by depositing said furnish on said moving foraminous support adding an organic permanent or temporary wet strength agent, the amount of wet strength agent added per ton of furnish is about 1 to 20 pounds, provided that the wet strength agent having a charge is added during the wet end paper making process while the wet strength agent having no charge is sprayed on the Yankee after creping or just before creping;
• partially through air drying the web;
• transferring said nascent web to said Yankee dryer, adhering said web to said Yankee dryer, creping said web from said Yankee dryer;
• recovering a creped, dried absorbent bathroom tissue having a serpentine configuration.
