Abstract

Provided are tissue webs, and products produced therefrom, that are generally durable, flexible and have improved cross-machine direction (CD) properties, such as CD tensile energy absorption (CD TEA), CD stretch and CD modulus. The inventive tissue products generally comprise a single tissue ply that has been prepared by through-air drying and more preferably by through-air drying without creping. Moreover, the products may be produced using a transfer fabric positioned between the forming fabric and the through-air drying fabric where the transfer fabric imparts the nascent web with a high degree of CD strain.

First claim

What is claimed is:

1. A rolled tissue product comprising a single ply tissue web spirally wound about a core, the single ply web having a basis weight from 32 to 40 gsm, a Stiffness Index of about 5.0 or less, a cross-machine direction (CD) tensile greater than about 550 g/3″ and a CD Stretch greater than about 14.0 percent.

2. The rolled tissue product of claim 1 wherein the single ply web has a GMT from about 700 to about 1,000 g/3″ and a geometric mean stretch (GM Stretch) of about 15 percent or greater.

3. The rolled tissue product of claim 1 wherein the single ply web has a CD TEA of about 6.0 g·cm/cm 2 or greater.

4. The rolled tissue product of claim 1 wherein the single ply web has a GM TEA of about 10 g·cm/cm 2 or greater.

5. The rolled tissue product of claim 1 wherein the single ply web has a Stiffness Index from 3.5 to 5.0.

6. The rolled tissue product of claim 1 wherein the single ply web has a CD Tensile from about 550 to about 750 g/3″ and a CD Stretch from about 14.0 to about 17.0 percent.

7. The rolled tissue product of claim 1 wherein the single ply web has a sheet bulk of about 10.0 cubic centimeters per gram (cc/g) or greater.

8. The rolled tissue product of claim 1 wherein the single ply web is uncreped.

9. The rolled tissue product of claim 1 wherein the single ply web is through-air dried and uncreped.

10. A rolled tissue product comprising a spirally wound uncreped and through-air dried single ply tissue web having a basis weight from 32 to 40 gsm, a Stiffness Index of about 5.0 or less, a GMT from 700 to 1,000 g/3″ and a CD Stretch of about 14.0 percent or greater.

11. The product of claim 10 wherein the web has a CD Tensile from about 550 to about 750 g/3″ and a CD Stretch from about 14.0 to about 17.0 percent.

12. The product of claim 10 wherein the web has a CD TEA of about 6.0 g·cm/cm 2 or greater.

13. The product of claim 10 wherein the web has a GM TEA greater than about 10 g·cm/cm 2 .

14. The product of claim 10 wherein the web Stiffness Index from 3.5 to 5.0.

15. The product of claim 10 wherein the web has a CD Tensile from about 575 to about 650 g/3″ and a CD Stretch from about 14.0 to about 17.0 percent.

16. The product of claim 15 wherein the web has a CD TEA from about 6.0 to about 8.0 g·cm/cm 2 .

17. The product of claim 16 wherein the web has a CD Slope less than about 3.0 kg.
