摘要： The present invention relates to a method for the continuous production of low thermal conductivity endless filament yarns with a compact, homogeneous structural morphology. The presently disclosed methods utilize safe and recyclable ionic liquids (IL) to produce carbon fiber precursors from cellulose. The fibers are produced by the carbonization of cellulose carbon fiber precursors. The precursor fiber filaments have an increased tear resistance with simultaneously sufficient elongation, a round or crenulated cross-section, and homogeneous fiber morphology. The filament yarns exhibit performance characteristics similar to those produced from traditional viscous rayon. The resulting fibers are especially suited for aerospace applications in composite materials used at the limits of high temperatures, for instance in structures found in rocket nozzles or atmospheric reentry heat shields on spacecraft.

摘要： The invention relates to molded cellulose bodies, in particular fibers, filaments, directly spun nonwovens, films, or foams which have flame-resistant properties. The fibers and filaments can be further processed as textiles into yarns, wovens, knitted fabrics, and nonwovens. The molded bodies are produced from solutions of cellulose and melamine cyanurate or cellulose and crosslinked or partially crosslinked melamine resin particles in an organic solvent. The melamine cyanurate or the melamine resin particles provide the molded cellulose bodies with flame-retardant properties. The molded cellulose bodies made of cellulose and melamine cyanurate or melamine resin particles can further contain flame retardants, in particular flame retardants which act synergistically, in a particulate form. The obtained textile fibers and nonwoven materials have a soft touch and can be processed or finished as filaments or yarns on conventional textile machines.

摘要： A method of producing regenerated cellulose and hemicellulose from a fibre pulp which is prepared by using chemical cooking. Hemicellulose and, correspondingly, cellulose is separated from the pulp, in order to form separate fractions, by dissolving them in such a solvent or an aqueous solution of it, from which they are precipitated by adding water, after which the regenerated hemicellulose and cellulose can be recovered. Hemicellulose-containing pulp, which for example is used as raw material of paper, can be efficiently fractionated into polymeric hemicellulose-rich fractions and very pure cellulose fractions, such as regenerated cellulose fibre, various cellulose particles or cellulose films.
