Estimating the term…
The present invention provides multi-layered tissue webs, and tissue product comprising the same, comprising long, high-coarseness wood pulp fibers selectively deposited in one or more outer layers of the multi-layered web. Surprisingly disposing long, high-coarseness wood pulp fibers in one or more outer layers, even in relatively modest amounts, may improve certain product properties, such as durability, without negatively affecting softness. In certain instances, both the softness and durability may be improved by selectively incorporating long, high-coarseness wood pulp fibers in one or more of the outer layers.
A tissue product comprising at least one multi-layered tissue web having a first and a second outer layer and a middle layer disposed there between, wherein the first and the second outer layers comprise from about 5 to about 20 weight percent (wt %) long, high-coarseness fiber having an average fiber length greater than about 2.0 mm and a coarseness of 20 mg/100 m or greater, the tissue product having a geometric mean tensile (GMT) from about 700 to about 1,200 g/3″ and a TS7 value less than about 12.0 dB V2 rms.
A method of forming a soft and durable wet laid tissue product comprising the steps of:
