Abstract
The present invention provides multi-layered tissue webs, and tissue products comprising the same, the multi-layered webs comprising wood fibers and non-wood cellulosic fibers where the non-wood cellulosic fibers are selectively deposited in one or more outer layers of the multi-layered web. Surprisingly disposing non-wood cellulosic fibers in the outer layers, even in relatively modest amounts, alters the machine and/or cross-machine direction properties of the resulting web, such that MD:CD tensile ratio may be reduced.
