Abstract
The present invention relates to a soft, thick, single-ply tissue having a serpentine configuration and to a process for the manufacture of such tissue product having a basis weight of at least about 15 lbs. per 3000 square foot ream and having low sidedness, said tissue exhibiting:a specific total tensile strength of between 40 and 200 grams per 3 inches per pound per 3000 square foot ream, a cross direction specific wet tensile strength of between 2.75 and 20.0 grams per 3 inches per pound per 3000 square foot ream, the ratio of MD tensile to CD tensile of between 1.25 and 2.75, a specific geometric mean tensile stiffness of between 0.5 and 3.2 grams per inch per percent strain per pound per 3000 square foot ream, a friction deviation of less than 0.250, and a sidedness parameter of less than 0.30.
