    摘要: A process for the preparation of regenerated cellulose shaped bodies from inning dopes comprising solutions of methylol derivatives of cellulose in organic solvent selected from dimethylformamide, dimethylacetamide, dimethylsulphoxide and N-methyl-pyrrolidone is described. The cellulose derivative is coagulated from the spinning dope in a coagulating bath, the main component of which is a high-boiling alcohol capable of reacting with the free (para)formaldehyde and with the bound (para)formaldehyde of the methylol derivative to a degree varying with the temperature. It is possible to prepare filaments and yarns having excellent characteristics by starting from solutions having high CH.sub.2 O and cellulose concentrations and high MS ratios.

    摘要: A process for the dissolution of cellulose in organic solvents such as dihylformamide, dimethylacetamide, and N-methylpyrrolidone is described which comprises contacting the cellulose with an excess of paraformaldehyde and with the solvent at elevated temperatures, preferably higher than 115.degree. C. The amount of paraformaldehyde used preferably corresponds to at least 13 CH.sub.2 O units per anhydroglucosidic unit of the cellulose. The solution obtained can be rendered stable at room temperature by heating it under stirring to lower the paraformaldehyde content, preferably to not less than 8 CH.sub.2 O units per anhydroglucosidic unit. Formed bodies of regenerated cellulose can be obtained from said solutions by coagulating them in an aqueous bath, which may be alkaline or may be a mixture of water and the solvent of the solution, or even by evaporating the solvent.
