Abstract
The present invention provides a wet-laid tissue product comprising regenerated cellulose fibers that can provide 25% or less of the total weight of the wet-laid tissue product. The regenerated cellulose fibers can have a denier of less than 0.9 and a fiber length of less than 6.0 mm. The wet-laid tissue product can provide improvements in softness at a given strength.
Claims18
A wet-laid tissue product comprising regenerated cellulose fibers providing between 0.1% to 25% of the total weight of the wet-laid tissue product, the regenerated cellulose fibers comprising a denier between 0.1 to 0.9 and a fiber length of less than 6.0 mm;
- wherein the wet-laid tissue product comprises a durability of greater than 30 for a GMT between 700 g/3″ and 1300 g/3″.
A wet-laid tissue product comprising regenerated cellulose fibers providing between 0.1% to 25% of the total weight of the wet-laid tissue product and a TS7 value≤0.0066×GMT+8.0752, wherein the GMT is between about 700 g/3″ to about 1300 g/3″, wherein the regenerated cellulose fibers comprise a denier between 0.1 to 0.9 and a fiber length of less than 6.0 mm.
