The invention relates to hydrophilic, humectant, soft, pliant, single-ply or multi-ply absorbent papers in the form of a bathroom tissue. These humectant paper products are formed by supplying a furnish to headbox comprising: Cellulosic papermaking fiber consisting essentially of recycle fiber, hardwood fiber, softwood fiber, and mixtures thereof; and optionally up to 50% synthetic fibers and a softener which has a melting range of about 0°-40°C. wherein the softener comprises an imidazoline moiety formulated in organic compounds selected from the group consisting of alkoxylated aliphatic polyols, alkoxylated aliphatic diols, aliphatic polyols, aliphatic diols and a mixture of these compounds, wherein the process of adding the softener is controlled to retain a ratio of the average particle size of dispersed softener to the average fiber diameter in the range of about 0.01 to 15 percent: wet pressing said nascent web, creping said web from said Yankee, and recovering the paper products. These products are also suitably prepared using through drying methods with or without the use of a Yankee Dryer, and the products exhibit a unique combination of properties designed to appeal to consumer preferences. In many applications, these products not to be creped, and in that case they do not have the serpentine configuration.
A hydrophilic, humectant, soft, pliant single-ply or multi-ply absorbent through dried bathroom tissue to which an organic permanent or temporary wet strength agent has been added, said bathroom tissue formed from cellulosic fibers and optionally up to 50% synthetic fibers and 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 polyols, alkoxylated diols, aliphatic diols, aliphatic polyols, and a mixture of these compounds, 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, the amount of wet strength agent added per ton of furnish is about 1 to 20 pounds.
A hydrophilic, humectant, soft, pliant single-ply or multi-ply through dried absorbent bathroom tissue to which an organic permanent or temporary wet strength agent has been added, the amount of wet strength agent added is about 1 to 20 pounds per ton of furnish, said bathroom tissue having a serpentine configuration formed from cellulosic fibers and optionally up to 50% synthetic fibers and a softener having a melting range of about 0°-40° C., 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, 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 polyols, alkoxylated diols, aliphatic diols, aliphatic polyols, and a mixture of these compounds;
