Soft through-air dried facial tissue
Disclosed am multi-ply tissue products, particularly creped and through-air dried facial tissue products, having improved strength and softness. For example, the products have a geometric mean tensile strength (GMT) greater than about 1,2000 g/3″, a geometric mean tensile energy absorption (GM TEA) of about 20 g·cm/cm 2 or greater and a TS7 value less than about 16.0. In certain instances, the tissue products also have a low degree of stiffness and a relatively smooth surface, such as a Stiffness Index less than about 8.00 and a TS750 value less than about 15.0. The tissue products may be prepared from webs manufactured by a print-crepe process that deposits a latex polymer on at least one of the outer surfaces of the tissue web.
