Abstract:
A single ply tissue paper comprising at least five layers joined in face-to-face relationship:two outer layers, each outer layer comprising greater than 50% relatively short papermaking fibers having fiber lengths of about 0.25 millimeters to about 1.5 millimeters, whereby said outer layers provide a soft tactile sensation to a user;two intermediate layers, said intermediate layers being juxtaposed with and between said outer layers; anda central layer, said central layer being disposed between and separating said intermediate layers, wherein one of said central layer and said intermediate layers comprises greater than 50% relatively long papermaking fibers having fiber lengths of about 2.0 millimeters or greater, said relatively long papermaking fibers imparting strength to said tissue paper, and the other of said intermediate layers and said central layer comprising greater than 50% low density, high bulking fibers selected from the group consisting of weakly bonded fibers. debonded fibers, curled fibers, and fibers combined with fillers, wherein said low density, high bulking fibers increase the bulk of said tissue paper.
