Abstract: An object is to provide an acid-type carboxymethylated cellulose nanofiber in which the viscosity is not excessively high at the time of preparing a dispersion liquid and the introduced carboxymethyl group is desalted to convert the acid type, and the acid-type carboxymethylated cellulose nanofiber has 0.01 to 0.50 of the degree of substitution with carboxymethyl group per glucose unit, wherein the B-type viscosity in an aqueous dispersion with a concentration of 0.95 to 1.05% by mass is 1000 mPa·s or more under the condition of 60 rpm and 20° C., and 7000 mPa·s or more under the condition of 6 rpm and 20° C.

Abstract: Densified textile aggregates are co-fed with a fuel into a partial oxidation gasifier. High solids concentrations in the feedstock composition can be obtained without significant impact on the feedstock composition stability and pumpability. A consistent quality of densified textile derived syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The densified textile derived syngas quality, composition, and throughput are suitable for produce a wide range of chemicals and polymers, including methanol, acetic acid, methyl acetate, acetic anhydride, and cellulose esters through a variety of reaction schemes in which at least a portion of the chemical or polymer originates with densified textile derived syngas.

Abstract: A process for forming a fiber tow, involves a wet spinning procedure comprising the steps of: dissolving cellulose pulp N in an alkaline aqueous solvent to form a cellulose spin dope composition, spinning the cellulose spin dope composition in a coagulation having a p H of more than 7.0, preferably a pH of at least 10, to produce a fiber tow, and passing the produced fiber tow through a sequence of consecutive stretching and washing steps in which the formed fiber tow is washed with a washing liquid by a counter-current flow washing procedure.

Abstract: The present invention is directed to a cellulosic fibre composition comprising regenerated cellulose and one or more additives, wherein
a) the cellulosic fibre composition is produced by injecting an aqueous alkaline spindope solution or suspension comprising dissolved cellulose in a concentration from about 5% to about 12% by weight of spindope and at least one of an additive and a nano-sized structured particulate filler through a nozzle into an alkaline coagulation bath forming cellulosic filaments; and
b) stretching or washing cellulosic filaments from a) in one or more stretching and washing baths forming a regenerated cellulosic fibre.
