The present invention is a method of making an ultra soft, multi-ply tissue using wet press technology and the product produced thereby.

Methods of making an ultra soft, high basis weight tissue and product produced thereby

Soft, bulky single-ply tissue having a serpentine configuration and low sidedness

Method of manufacturing a soft, bulky single-ply tissue having a serpentine configuration and low sidedness

Soft, bulky single-ply tissue having a serpentine configuration and low sidedness and method for its manufacture

Pattern for a paper product

The present invention relates to a soft, thick, single-ply tissue and to a process for the manufacture of such tissue product having a basis weight of at least about 15 lbs./3,000 square foot ream and having low sidedness, said tissue exhibiting: a specific total tensile strength of between 40 and 75 grams per 3 inches per pound per 3000 square feet ream, a cross direction specific wet tensile strength of between 2.75 and 7.5 grams per 3 inches per pound per 3000 square feet 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 1.2 grams per inch per percent strain per pound per 3000 square feet ream, a friction deviation of less than 0.225, and a sidedness parameter of less than 0.275.

A process for producing a creped sheet as well as a creping blade and creped paper product formed by such blade is set forth with the process including the steps of adhering a cellulosic web to a moving surface, providing a stepped creping blade disposed to crepe the cellulosic web from the moving surface and creping the cellulosic web from the moving surface forms a creped paper product having greater bulk and absorbency than previously prepared creped paper products. The stepped creping blade used in carrying out the process of the present invention includes an elongated body adapted to be engagable against, and span the width of, the moving surface, the elongated body having a cross section including a relief surface generally facing toward the moving surface, a back surface substantially parallel to the relief surface and generally facing away from the moving surface, a top surface adjacent both the relief surface and a recessed surface with the recessed surface being adjacent both the top surface and the back surface and forming a contact edge with the top surface such that the contact edge engages against the moving surface for creping the cellulosic web from the moving surface. The top surface and the recessed surface form a back step edge while the recessed surface and the back surface form a trailing edge. When utilizing such a blade configuration, the process further includes the steps of first contacting the cellulosic web conveyed by the moving surface with the contact edge, then optionally contacting the cellulosic web creped by the contact edge with the back step edge and subsequently contacting the cellulosic web creped by the contact edge with the trailing edge.
