Abstract
The present invention provides a treated fiber having reduced hydrogen bonding capabilities, which may be useful in the production of tissue products having improved bulk and softness. The treated fiber comprises a water-insoluble inorganic compound that is generated in situ by reacting at least one compound selected from the group consisting of a silicate, a silyl, a silane, and an alkaline metal and a precipitation agent in the presence of the fiber at or above the critical fiber consistency.
Claims4
A tissue product comprising at least one multi-layered tissue web having a first fibrous layer, a second fibrous layer, and a third fibrous layer, the first and third fibrous layers comprising untreated cellulosic fibers and the second fibrous layer comprising treated fiber comprising at least about 5,000 ppm water-insoluble inorganic selected from silicone, aluminum and zinc, wherein the treated fiber comprises at least about 5 percent of the total weight of the multi-layered web.
