Official abstract text for this publication.
The present disclosure is directed to creped tissue webs, and products produced therefrom. The creped tissue webs and tissue products made therefrom are soft and strong, such as having a TS7 value less than about 8.0. Moreover, the tissue of the present disclosure also preferably has low TS750 values such as less than about 7.0. Further, while webs prepared according to the present disclosure have low TS7, and in certain embodiments low TS750 values, they are also strong enough to withstand use.

We claim: 1. A creped multi-ply tissue product comprising at least one creped tissue ply having a first and a second side, wherein a water-soluble creping composition selected from the group consisting of a polyether, a polyamide, a polyvinyl alcohol, a cationic starch, and a cationic polyamide-epihalohydrin and combinations thereof, is disposed on at least the first or the second side the tissue product having a basis weight of at least about 20 gsm, a GMT of at least about 600 g/3″, and a TS7 value from about 4.0 to about 8.0 dB V2 rms. 2. The creped multi-ply tissue product of claim 1 wherein the product has a GMT from about 600 g/3″ to about 1,000 g/3″ and a TS750 value less than about 7.0 dB V2 rms. 3. A multi-ply tissue product comprising at least one creped tissue web prepared by wet forming a fibrous web, applying a creping composition consisting essentially of a polyvinyl alcohol and a second component selected from the group consisting of a polyether, a polyamide, a water soluble cationic polymer, carboxymethyl cellulose, hydroxymethyl cellulose and hydroxypropyl cellulose to a dryer surface, transferring the fibrous web to the dryer surface and creping the fibrous web to remove the web from the dryer surface, the tissue product having a TS7value from about 4.0 to about 8.0 d V 2 rms and a GMT of at least about 600 g/3″. 4. The multi-ply tissue product of claim 3 wherein the water soluble cationic polymer is a cationic starch, a tertiary aminoalkyl ether, a quaternary ammonium alkyl ether, a cationic polyamide-ephihalohydrin or a quaternary ammonium salt having the general formula: (R 1′ ) 4-b −N + −(R 1″ ) b X − wherein R 1′ is a C 1-6 alkyl group, R 1″ is a C 14-22 alkyl group, b is an integer from 1 to 3 and X − is any suitable counterion. 5. The multi-ply tissue product of claim 3 wherein the fibrous web comprises a first and a second layer, the first layer comprising hardwood kraft fibers and the second layer comprising softwood kraft fibers. 6. The multi-ply tissue product of claim 3 further comprising the step of calendering the creped fibrous web. 7. The multi-ply tissue product of claim 3 further comprising the step of treating the creped fibrous web with a polysiloxane. 8. The multi-ply tissue product of claim 3 further comprising the step of treating the creped fibrous web with a mineral oil, aloe extract, vitamin-E or a lotion. 9. The multi-ply tissue product of claim 3 wherein the GMT is from about 600 to about 1,000 g/3″ and a basis weight greater than about 25 gsm. 10. The multi-ply tissue product of claim 3 wherein the tissue product has a TS750from about 4.0 to about 6.0 d V 2 rms. 11. A multi-ply tissue product comprising at least one creped tissue web prepared by wet forming a fibrous web, applying a creping composition consisting essentially of two or more components selected from the group consisting of polyethers, polyamides, polyvinyl alcohol, carboxymethyl cellulose, hydroxymethyl cellulose, hydroxypropyl cellulose, and water soluble cationic polymers to a dryer surface, transferring the fibrous web to the dryer surface comprising the water soluble creping composition and creping the fibrous web to remove the web from the dryer surface, the tissue product having a TS7 value from about 4.0 to about 8.0 d V 2 rms and a GMT of at least about 600 g/3″. 12. The multi-ply tissue product of claim 11 wherein the water soluble cationic polymer is selected from the group consisting of cationic starch, tertiary aminoalkyl ethers, quaternary ammonium alkyl ethers, cationic polyamide-ephihalohydrin, and quaternary ammonium salts having the general formula: (R 1′ ) 4-b −N + −(R 1″ ) b X − wherein R 1′ is a C 1-6 alkyl group, R 1″ is a C 14-22 alkyl group, b is an integer from 1 to 3 and X − is any suitable counterion. 13. The multi-ply tissue product of claim 11 further comprising the step of calendering the creped fibrous web. 14. The multi-ply tissue product of claim 11 further comprising the step of treating the creped fibrous web with a polysiloxane. 15. The multi-ply tissue product of claim 11 further comprising the step of treating the creped fibrous web with a mineral oil, aloe extract, vitamin-E or a lotion. 16. The multi-ply tissue product of claim 11 wherein the GMT is from about 600 to about 1,000 g/3″ and a basis weight greater than about 25 gsm.
