Dissolved air de-bonding of a tissue sheet
Tissue papers and methods of making are disclosed herein. In one aspect, a tissue paper is substantially free of a chemical debonder and has a geometric mean tensile (GMT) in a range between about 500 and about 5,000 g/3 inches (g/3 in.) and a caliper in a range between about 50 and about 350 mils/8 sheets.
1. A tissue paper having less than 4 pounds per ton of a chemical debonder and having a geometric mean tensile (GMT) in a range between about 500 and about 5,000 g/3 inches (g/3 in.) and a caliper in a range between about 50 and about 350 mils/8 sheets;
wherein the tissue paper is formed by impregnating a fiber slurry comprising cellulosic fibers with a compressed water-soluble gas under a super-atmospheric pressure in a contained environment, and wherein the tissue paper is formed by a conventional wet press (CWP).
2. The tissue paper of claim 1 , wherein the chemical debonder is present in an amount of less than 2 lb/ton chemical debonder.
3. The tissue paper of claim 1 , wherein the tissue paper has a basis weight in a range between about 5 lb/3,000 ft 2 and about 45 lb/3,000 ft 2 .
4. A tissue paper void of a chemical debonder and having a GMT in a range between about 500 and about 5,000 g/3 in. and a caliper in a range between about 50 and about 350 mils/8 sheets;
wherein the tissue paper is formed by impregnating a fiber slurry comprising cellulosic fibers with a compressed water-soluble gas under a super-atmospheric pressure in a contained environment, and wherein the tissue paper is formed by a conventional wet press (CWP).
5. The tissue paper of claim 4 , wherein the tissue paper has a basis weight in a range between about 5 lb./3,000 ft 2 and about 45 lb./3,000 ft 2 .
6. The tissue paper of claim 5 , wherein the tissue paper has a basis weight in a range between about 8 lb./3,000 ft 2 to about 30 lb./3,000 ft 2 .
