| titleOfInvention | High purity stratified tissue and method of making same |
| abstract | A Foam-Formed nonlaminated stratified paper tissue and method of making the same includes a first zone of foam-formed paper tissue formed from a furnish which is relatively rich in hardwood fiber. A second zone of foam-formed paper tissue is formed from a furnish which is relatively rich in softwood fiber. The second zone is formed unitary and entangled with the first zone to form a nonlaminated stratified paper tissue. A high softness integument is defined adjacent to an outer surface of the first zone and a substratum is defined adjacent to a surface of the second zone spaced away from the integument. The integument on the outer surface of the first zone includes an enriched region wherein the hardwood fiber content is greater than that obtainable in the corresponding region of a tissue obtained from furnishes having the same compositions under the same conditions but employing water-forming instead of foam-forming. The substratum on the surface of the second zone includes a region enriched in softwood fiber. The enriched region of substantially pure hardwood fiber provides an extremely soft and smooth surface as detected by human somatic sensibility. |
