Crosslinked cellulose as low-cost precursor in production of high-grade cellulose derivatives and related technology

A pulp in accordance with a particular embodiment includes crosslinked cellulose fibers. The pulp can have high brightness, reactivity, and intrinsic viscosity. The pulp, therefore, can be well suited for use as a precursor in the production of low-color, high-viscosity cellulose derivatives. A method in accordance with a particular embodiment...

Methods of developing plant somatic embryos

Methods of developing plant somatic embryos include incubating the plant somatic embryos at a first temperature for a first period of time followed by storing the plant somatic embryos at a second temperature for a second period of time. The first temperature can be in the range of about 23°... Weyerhaeuser Nr Company

Modified fiber from shredded pulp sheets, methods, and systems

Methods of forming crosslinked cellulose include mixing a crosslinking agent with cellulose mat fiber fragments composed of hydrogen-bonded cellulose fibers and having a solids content of about 45-95% to form a substantially homogenous mixture of non-crosslinked, individualized cellulose fibers, drying the resulting mixture to 85-100% solids, then curing the dried...

Methods for improving plant embryo development

Provided is a method of improving plant embryo development and/or germination. The method comprises developing plant embryos in the presence of nitric oxide (NO). The method entails the step of incubating plant embryogenic suspensor mass (ESM) in, or on, a development medium containing a nitric oxide donor for a period... Weyerhaeuser Nr Company

Building products with fire-resistant claddings

A building product having improved fire resistance by virtue of solid fire-resistant cladding material attached to at least a portion of one or more surfaces of the building product. The solid fire-resistant cladding material includes wood fiber and binder. The building product can be a wood-based building product, and can... Weyerhaeuser Nr Company

Grafted crosslinked cellulose

Grafted, crosslinked cellulosic materials include cellulose fibers and polymer chains composed of at least one monoethylenically unsaturated acid group-containing monomer (such as acrylic acid) grafted thereto, in which one or more of said cellulose fibers and said polymer chains are crosslinked (such as by intra-fiber chain-to-chain crosslinks). Some of such... Weyerhaeuser Nr Company

Methods of improving germination of plant embryos

A method of improving germination of plant embryos is provided. The method entails treating a culture of plant tissue with a liquid multiplication medium comprising a plant non-metabolizable sugar. Also provided is a multiplication medium for liquid cultures of plant cells comprising isomaltulose.... Weyerhaeuser Nr Company

Thermally insulating low-density structural wooden composite

Wood-based composites, and methods for their manufacture, are provided. The composites include oriented wooden strands and cured bonding resin connecting adjacent strands. The composites are relatively low-density, having an average dry density of the wooden composites of about 15-28 pounds per cubic foot (pcf). The unique composition of the composites...
