Abstract
Highly textured tissue sheets, particularly suitable for use as bath tissue, are produced by throughdrying and have a low number and/or low amount of pinholes. The low number or amount of pinholes is provided by using a throughdrying fabric having parallel wide ridges with a height suited to the particular tissue sheet being produced.
