Abstract:
1. A process for producing a sheet product comprising: applying an aqueous polyolefin dispersion to a moving creping surface, wherein said aqueous polyolefin dispersion comprises at least one thermoplastic resin, water, and at least one dispersing agent, wherein said aqueous polyolefin dispersion has an average particle size in the range of from 0.05 μm to 5 μm and a pH in a range of from 7 to 11, and wherein said dispersion comprises more than 25 percent by weight of water; pressing a base sheet having an initial basis weight against the creping surface after the aqueous polyolefin dispersion has been applied, the aqueous polyolefin dispersion adhering the base sheet to the creping surface, wherein said base sheet comprises less than 50 percent by weight of cellulosic materials; and removing the base sheet from the creping surface, wherein the aqueous polyolefin dispersion transfers to the base sheet such that the basis weight of the base sheet increases by at least about 1 percent by weight.
