Producing regenerated cellulosic fiber, comprises mixing a viscose with a dispersion of particles of a flame retardant solid matter, in a dispersion medium with a specific ratio, and carrying out wet spinning of the obtained mixture according to specific spinning parameters, molding the particles, whose dimension in a particle major axis is greater than in the two orthogonal axes of secondary particles, and aligning the particle major axes in the fiber in a preferred direction parallel to their spin direction. An independent claim is also included for the cellulose regenerated fiber spun from viscose that is doped with flame-retardant particles, produced by the above method, where the decrease in a dry tensile strength of the cellulose regenerated fiber spun from viscose doped with flame-retardant particles with respect to an identical cellulose regenerated fiber produced from an un-doped viscose, is less than 28%, preferably less than 20%. |
