Abstract (en)
[origin: WO2004081267A1] The method of making modified cellulose fibers from cellulose solution in N-methylmorpholine-N-oxide, which involves mixing ccllulose with aqueous N-methylmorpholine-N-oxide, evaporating and filtration of the spinning solution subsequently forced through the holes in the spinning nozzle into the aqueous spinning bath, finally rinsing, drying and conditioning, is described by the fact that modifying substances such as ceramic oxides, metal oxides or their mixtures, if necessary containing additional surfactants, carbon, if necessary modified with silver, bactericidal agents, acid-base indicators, thermo chromic dyes with nano- or supra molecular break-up are added into the cellulose, the solvent or the spinning solution.
