Abstract

In a process for producing regenerated cellulose fibers, in which particles of a flame-retardant solid are incorporated into the fiber, the particles are placed into a mold, the dimension of which in a major axis of the particle is greater than in the two orthogonal minor axes of the particle, and the major axes of the particles in the fiber are aligned in a preferential direction parallel to the spinning direction thereof.
