| titleOfInvention | PROCEDURE FOR OBTAINING FIBERS AND YARNS BASED ON CELLULOSIC COMPOUNDS. |
| abstract | A method is disclosed for producing cellulosic and/or polynosic fibres having flame-resisting properties, the improvement consisting in the fact that a composite viscose is spun in an acidic bath, said composite viscose being obtained by the association in an aqueous solvent, of cellulose xanthate with a phosphorus and nitrogen compound, dissolved in the same aqueous solvent and capable of being converted, while cellulose is being regenerated in said acidic bath, into a state of substantial insolubility. The phosphorus and nitrogen compound is a compound obtained by reacting a phosphonium derivative with aminoacids and amines and/or ammonia. A preferred compound is tetrakis-hydroxymethylphosphonium chloride. By so doing, an efficient flame-retarding protection is obtained for the fibre without sacrificing the physical properties thereof. Critical quantities, reaction conditions and test results are reported. |
