Abstract

A wiping implement suitable for use as a bath tissue can be formed into sheets, each sheet comprising at least one ply of a paper web having a basis weight of at least about 25 lb/3000 square feet. The sheet can have a width of at least about 4.5 inches and temporary wet tensile properties. The sheet of the present invention can have an area of at least about 30 square inches. In a multiple ply embodiment, the sheet can have an optimized basis weight of at least about 42 lb/3000 square feet while maintaining nearly the same amount of actual total fiber usage per cleaning task as current premium bath tissues.
