摘要： The present disclosure describes a method for the production of a spinning dope composition, said method comprising a homogenization involving mixing a cellulosic pulp material in alkali solution, mixing implying supplying a power density to agitators used in the homogenization of at least 150 kW/m3 (KW supplied to agitators per mixed unit of liquid volume), and thereafter a dissolution involving mixing of the cellulosic pulp material in the alkali solution to obtain a spinning dope composition, wherein the power density supplied to agitators used in the dissolution step is maximum 75 kW/m3 (KW supplied to agitators per mixed unit of liquid volume); and wherein the cellulosic pulp material in alkali solution is kept at a temperature of less than 0° C. during the homogenization and during at least part of the dissolution. The present disclosure is also directed to a system intended for the production of a spinning dope composition.

摘要： Provided are: a cellulose fiber manufacturing method for suppressing the occurrence of thread breakage in a spinning step and unevenness in the physical properties of obtained fibers, thus enabling stable spinning; and cellulose fibers that are highly strengthened, in which fibrillation is suppressed, and that have a pleasant texture. The present invention provides a cellulose fiber manufacturing method including the following steps: a solution preparation step for dissolving cellulose in a mixed solvent of an aprotic polar solvent and a quaternary onium salt; a discharge step for discharging the obtained solution in a fibrous form through a spinneret, the moisture content of the solution at the time of discharging falling within the range from 0.05 mass % to 8 mass %; and a solidification step for solidifying the discharged fibers in a water-based solidification bath containing water and the mixed solvent.

摘要： A cellulose saccharification method including an introduction step of introducing water, a raw material containing cellulose, and a surfactant into a saccharification vessel so as to obtain a liquid mixture, an agitation step of agitating the liquid mixture due to rotation of an impeller portion, and a detection step of detecting a torque sensed by the impeller portion, wherein regarding the agitation step, after agitation is performed until an amount of the torque changed in a unit time period becomes less than or equal to a predetermined value, when the torque is more than or equal to a threshold value, the surfactant is additionally introduced into the liquid mixture, or when the torque is less than the threshold value, a pH adjuster and an enzyme are introduced into the liquid mixture.

摘要： The invention relates to separated, decompacted, cellulose-based fibres acquired from a vegetable raw material, wherein the separated, decompacted, cellulose-based fibres have an aspect ratio after soaking in water of longitudinal diameter to transverse diameter of 1:1 to 1000:1 and a water-binding capacity of >200 wt. % and a water retention capacity of >50%, and a method for acquiring and producing these separated, decompacted cellulose-based fibres. The purification method involves incubation of the vegetable material with an aqueous decomposition solution containing at least one dissolved amino acid and/or peptide with 2-50 amino acids to decompose the compacted cellulose-based fibres.
