WHAT IS CLAIMED IS:

1. A tissue product comprising at least one tissue web, the tissue web comprising synthetic fiber having at least one cross-section dimension less than about 20 microns, the tissue product having a geometric mean tensile (GMT) greater than about 800 g/3" and a geometric mean slope (GM Slope) less than about 10.0 kg.

2. The tissue product of claim 1 wherein the tissue web is substantially free from cellulosic fibers having an average fiber length greater than about 2.0 mm.

3. The tissue product of claim 1 wherein the tissue web comprises from about 10 to about 30 percent, by weight of the tissue web synthetic fiber.

4. The tissue product of claim 1 wherein the synthetic fiber has a substantially circular cross section and a diameter from about 0.5 to about 10 microns.

5. The tissue product of claim 1 wherein the synthetic fiber has a substantially rectangular cross section with a width dimension that is greater than the height dimension and wherein the height dimension is from about 0.5 to about 10 microns.

6. The tissue product of claim 5 wherein the synthetic fiber has a width dimension less than about 25 microns.

7. The tissue product of claim 1 having a GMT from about 800 to about 1200 g/3" and a GM Slope from about 5.0 to about 8.0 kg.

8. The tissue product of claim 1 having a GMT from about 800 to about 1200 g/3" and a Stiffness Index from about 4.0 to about 6.0.

9. The tissue product of claim 1 , wherein the product is substantially free from latex binder and has an Absorbent Capacity greater than about 6.0 g/g and a CD Wet/Dry Ratio greater than about 0.40.

10. The tissue product of claim 1 having an Absorbent Capacity from about 6.5 to about 7.0 g/g and a CD Wet/Dry Ratio from about 0.42 to about 0.50.

11 . The tissue product of claim 1 wherein the tissue product comprises a single-ply multi-layered web having a first and second outer layer and a middle layer disposed there between.

12. The tissue product of claim 11 wherein the synthetic fiber is selectively disposed in the middle layer and comprises from about 10 to about 30 percent of the weight of the tissue web.

13. A tissue product comprising at least one wet laid multi-layered tissue web comprising a fiber furnish consisting essentially of synthetic fibers and short cellulosic fibers, the multi-layered tissue web having a first and second outer layer and a middle layer disposed there between where the synthetic fibers are selectively disposed in the middle layer and the first and second layers are substantially free from synthetic fibers, the tissue product having a GMT greater than about 800 g/3" and a GM Slope less than about 10.0 kg.

14. The tissue product of claim 13 wherein the synthetic fiber is n on -fibri Hated and has at least one cross-section dimension less than about 20 microns and an average fiber length from about

1.0 to about 5.0 mm.

15. The tissue product of claim 13 wherein the tissue web comprises from about 10 to about 30 percent, by weight of the tissue web, synthetic fiber.

16. The tissue product of claim 13 wherein the synthetic fiber has a substantially circular cross section and a diameter from about 0.5 to about 10 microns.

17. The tissue product of claim 13 having a GMT from about 800 to about 1200 g/3" and a GM Slope from about 5.0 to about 8.0 kg.

18. The tissue product of claim 13 having a GMT from about 800 to about 1200 g/3" and a Stiffness Index from about 4.0 to about 6.0.

19. The tissue product of claim 13 wherein the product is substantially free from latex binder and has an Absorbent Capacity greater than about 6.0 g/g and a CD Wet/Dry Ratio greater than about 0.40.

20. A method of forming a wet laid tissue web comprising the steps of:

a. Providing a first fiber furnish consisting essentially of short cellulosic fibers; b. Providing a second fiber furnish consisting essentially of synthetic fibers and short cellulosic fibers;

c. Depositing the first and second fiber furnish on a forming fabric to form a wet tissue web;

d. Partially dewatering the wet tissue web; and

e. Drying the tissue web, wherein the web has a GMT greater than about 800 g/3" and a GM Slope less than about 15.0 kg.

21 . The method of claim 20 further comprising the steps of (f) creping the tissue web and (g) plying two webs together to form a tissue product, wherein the tissue product has a GMT greater from about 800 to about 1 ,200 g/3" and a GM Slope from about 6.0 to about 12. Kg.

22. The method of claim 20 wherein the drying step comprises through-air drying the web, and wherein the web has a GMT from about 800 to about 1200 g/3" and a GM Slope from about 5.0 to about 8.0 kg.

23. The tissue product of claim 22 having an Absorbent Capacity from about 6.5 to about

7.0 g/g and a CD Wet/Dry Ratio from about 0.42 to about 0.50.

24. The method of claim 20 wherein the synthetic fiber has at least one cross-section dimension less than about 20 microns.

25. The tissue product of claim 20 wherein the synthetic fiber is a n on -fibri Hated polyethylene terephthalate (PET) fiber having a substantially circular cross section and a diameter from about 0.5 to about 10 microns.

26. The tissue product of claim 20 wherein the tissue web comprises from about 10 to about 30 percent, by weight of the tissue web synthetic fiber.
