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.
Claims14
A tissue product comprising at least one multi-layered tissue web having a first outer layer, a second outer layer and a middle layer disposed therebetween, wherein the first and the second outer layers comprise unrefined non-wood cellulosic fiber and the middle layer is substantially free from non-wood cellulosic fiber, the tissue product comprising at least 10 percent, by weight of the product, unrefined non-wood cellulosic fiber and having a geometric mean tensile (GMT) of about 700 g/3″ or greater and geometric mean slope (GM Slope) from about 6.0 to about 10.0 kg.
