Abstract: The invention is based on the discovery that the wood of certain trees having genetically modified lignins has plastic properties far greater than that of trees of the general population of the same species. In particular, trees have been found to have significantly increased plasticity in which the lignin is of a less crosslinked or more linear type, of lower molecular weight, of a relatively higher content of lignin precursor monomers or oligomers, or is more readily extractable by the usual methods. Wood from these trees can be readily molded by pressure and heat into two or three dimensional articles. The ability to be molded can be significantly enhanced by the addition of plasticizers.

Abstract: The present invention is directed to methods of making lyocell fibers. In particular, the process includes reducing the average degree of polymerization of a pulp to about 200 to 1100 without substantially reducing the hemicellulose content of the pulp, and reducing the copper number to less than 2.0.

Abstract: The present invention provides compositions, useful for making lyocell fibers, having a high hemicellulose content, a low copper number and including cellulose that has a low average degree of polymerization (D.P.) and a narrow molecular weight distribution. Further, the present invention provides processes for making compositions, useful for making lyocell fibers, by contacting an alkaline pulp having a high hemicellulose content of at least about 7% with an oxidant sufficient to reduce the average degree of polymerization to about 200 to 1100 without substantially reducing the hemicellulose content or increasing the copper number of the pulp.

Abstract: The invention is a shipping container blank whereby all surfaces and edges are sealed by an overlying a plastic film material. A container subsequently made from the blank is rendered highly water resistant. The film material is applied to both sides of the blank and severed from the supply source. The covered blank is then heated above the softening point of the film. The film becomes bonded to the surfaces of the blank and sags around the edges and into any openings so that the film on the two sides of the blank come into contact and are sealed to each other. The edges and any slits and cutouts are then trimmed, as by a die cutter, while preserving the seals along the edges. Containers made by the process can generally be recycled, in contrast to wax or resin impregnated corrugated board.

Abstract: The present invention is directed to a lyocell fiber having a high hemicellulose content. The fibers are readily cut into staple lengths and can be spun into yarns with excellent knitting and weaving characteristics which dye exceptionally well. The fibers have a cotton-like denier.

Abstract: The present invention is directed to a pulp useful for making lyocell fibers. The pulp has a degree of polymerization from about 300 to about 1000; an alpha cellulose content of less than about 90% and in one instance can be made in a roll form. The degree of polymerization can be modified by acid hydrolysis, steam explosion; or alkaline enzymate degradation.

Abstract: The present invention provides lyocell fibers made from compositions having a high hemicellulose content of at least 5% by weight, a low kappa number of less than 2.0 and including cellulose that has a low average degree of polymerization (D.P.) value of about 200 to 1100, and a narrow molecular weight distribution (R) of less than 2.8.

Abstract: A method and media for producing bacterial cellulose under agitated culture conditions resulting in sustained production over an average of 70 hours of at least 0.1 g/liter per hour are achieved. A unique reticulated cellulose product is produced using the methods and conditions claimed, and may be converted to of a sheet characterized by substantial resistance to densification and great tensile strength when produced by sheet forming means. Acetobacter strains are identified as stable under agitated culture conditions and exhibit substantially reduced gluconic and keto-gluconic acids production.

The water-borne binding agent may be a starch, a modified starch, a polyvinyl alcohol, a polyvinyl acetate, a polyethylene/acrylic acid copolymer, an acrylic acid polymer, a polyacrylate, a polyacrylamide, a polyamine, guar gum, an oxidized polyethylene, a polyvinyl chloride, a polyvinyl chloride/acrylic acid copolymer, an acrylonitrile/butadiene/styrene copolymer or polyacrylonitrile. A method for making the paperboard is disclosed.

Abstract: The invention is lyocell fiber characterized by a pebbled surface as seen at high magnification and having a variable cross section and diameter along and between fibers. The fiber is produced by centrifugal spinning, melt blowing or its espunbonding variation. The fibers can be made in the microdenier range with average weights as low as one denier or less. The fibers have inherently low gloss and can be formed into tight yarns for making fabrics of very soft hand. Alternatively, the fibers can be formed into self bonded nonwoven fabrics.
