The present invention describes special cellulose compositions that allow a lyocell fiber with a reduced cellulose content to be produced on a stable industrial scale, as well as the lyocell fiber produced from it.

Fibrous structures that exhibit a pore volume distribution such that greater than about 50% of the total pore volume present in the fibrous structure exists in pores of radii of from about 101 m to about 200 m, and methods for making such fibrous structures are provided.

The process includes pretreating the biomass with a first basic solution such as sodium hydroxide and mechanically altering the fibers to provide a fluidized biomass. The fluidized biomass is then subjected to high frequency pulses and shear forces without denaturing the individual components of the biomass. The biomass is then subjected to compressive force to separate a first liquid fraction from a first fractionated biomass. The first fractionated biomass may again then be subjected to the same high frequency pulses and shear forces as previously, particularly if there are hemicellulose and/or sugars still present in the first fractionated biomass. Compressive forces are used to separate a second liquid fraction from a second fractionated biomass. The second fractionated biomass is subjected to oxidation such as with hydrogen peroxide at a pH of 8 to 12. The second fractioned biomass is then subjected to compressive forces to separate one or more water insoluble components of the biomass in water soluble form.

A label assembly including one or more dissolvable thermal direct adhesive labels and methods of assembly and use. According to one embodiment, each label includes a base layer, a thermal direct layer, an adhesive layer, and a barrier layer. The base layer, which has an upper surface and a lower surface, is water-dissolvable and may be made of a water-dissolvable paper. The thermal direct layer is positioned directly over the upper surface of the base layer and functions in the conventional manner to produce markings therein in response to heat. The adhesive layer is water-dissolvable and is positioned below the lower surface of the base layer. The barrier layer, which is positioned directly below the lower surface of the base layer and directly over the adhesive layer, serves to prevent migration of the adhesive layer through the base layer and into contact with the thermal direct layer.
