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 multiple tissue plies, such as two or more plies, that have been prepared by through-air drying and more preferably by through-air drying without creping. Moreover, the plies may be produced in a through-air drying process that utilizes 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.
