ABSTRACT:
A web comprised of lyocell fibers. The web may be a homogeneous blend of fibers with lyocell fibers having a length of less than about 6 mm as a portion of the blend. The web may be a multi layered single ply with lyocell fibers in one or more layers. The web may be composed of multiple plies, with component plies composed of multiple layers. The length and proportion of the lyocell fibers in the respective layers of the component plies may vary intentionally from layer to layer.
