Abstract:
1. A process for producing a tissue product comprising: applying an aqueous polyolefin dispersion to a tissue web, the tissue web having a bulk greater than 3 cc/g and containing cellulose fibers in an amount greater than 50% by weight, the aqueous polyolefin dispersion comprising at least one thermoplastic polyolefin resin, water, and at least one dispersing agent, the thermoplastic polyolefin resin, the thermoplastic polyolefin resin comprising an alpha-olefin interpolymer of ethylene or propylene and at least one comonomer, each comonomer being selected from the group consisting of octene, heptene, hexene, decene, and dodecene, the thermoplastic polyolefin resin having an average particle size in the dispersion in the range of from 0.05 microns to 5 microns and a pH in a range of from 7 to 11, the aqueous polyolefin dispersion comprising more than 25% by weight of water; and forming a discontinuous coating on at least one side of the tissue web from the aqueous polyolefin dispersion, the discontinuous coating defining openings that allow liquids to be absorbed by the tissue web.
