Tissue products containing non-fibrous polymeric surface structures and a topically-applied softening composition
View Patent ↗Soft tissue products with a good rate of absorbency, such as facial and bath tissue, are provided by forming a tissue sheet with a non-fibrous polymeric surface structure and thereafter topically applying a softening composition comprising a polysiloxane, a fatty alkyl derivative and glycerin. The non-fibrous polymeric surface structure is created by applying an additive composition to the surface of a tissue sheet prior to or after drying. The additive composition can be an aqueous dispersion containing an alpha-olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The alpha-olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer.
1. A tissue sheet comprising non-fibrous polymeric surface structures and further comprising from about 0.2 to about 20 dry weight percent of a topically applied softening composition, said softening composition comprising, based on the total amount of actives in the composition, from about 5 to about 40 weight percent polysiloxane, from about 10 to about 50 weight percent of an fatty alkyl derivative, from about 20 to about 80 weight percent glycerin, wherein the tissue sheet has a geometric mean tensile strength of from about 600 to about 1300 grams per 3 inches.
2. The tissue sheet of claim 1 wherein the amount of the softening composition is from about 0.5 to about 10 dry weight percent.
3. The tissue sheet of claim 1 wherein the amount of the softening composition is from about 0.5 to about 5 dry weight percent.
4. The tissue sheet of claim 1 having an absorbent rate, as measured by the Water Drop Absorbency Rate, of about 40 seconds or less.
5. The tissue sheet of claim 1 having an absorbent rate, as measured by the Hercules Size Test, of from about 40 seconds or less.
6. The tissue sheet of claim 1 wherein the non-fibrous polymeric surface structures comprise a polymeric blend of an ethylene alpha-olefin copolymer and an ethylene-carboxylic acid copolymer.
7. The tissue sheet of claim 6 wherein the ethylene alpha-olefin copolymer is an ethylene and octene copolymer.
8. The tissue sheet of claim 6 wherein the ethylene-carboxylic acid copolymer is an ethylene-acrylic acid copolymer.
