ABSTRACT:
A regenerated cellulose composition having excellent adsorptivity and flame resistance prepared by a process in which viscose, a solvent-adsorbing active carbon in the form of an aqueous dispersion and a specific phosphorus flame retarder are extruded into a coagulation bath to regenerate cellulose which is dried at a temperature not lower than the boiling point of the solvent, whereby the adsorptivity of active carbon is maintained at a high level while a flame resistance is imparted to cellulose.
