ABSTRACT:
A tissue product containing a cellulosic fibrous material and less than about 10 wt. % of a superabsorbent material (e.g., fibers, particles, etc.) is provided. In some instances, the superabsorbent material can absorb between about 100 to about 350 grams of an aqueous solution per gram of superabsorbent material. In some embodiments, the superabsorbent material can be applied at the stock-preparation stage of a papermaking process, and can be provided in a dry or preswollen state.
