Abstract
The present invention provides tissue webs and products that are manufactured by non-compressive dewatering and/or drying methods, such as through-air drying, where the webs and products comprise cross-linked fiber. The non-compressively dewatered tissue webs and products have improved sheet bulk and z-direction properties. For example, in one embodiment, the invention provides through-air dried tissue products having good sheet bulk and resiliency, such as a sheet bulk greater than about 15 cc/g and Compression Energy (E) greater than about 1.30 N/m. Surprisingly the foregoing products have sufficient strength to withstand use, such as a GMT greater than about 600 g/3″, but are not overly stiff, generally having a Stiffness Index less than about 12.
