METHOD OF TREATMENT WITH FLAME RETARDANT AND FIRE-HARDENED MATERIAL OF CELLULOSE FIBERS Russian patent published in 2013 - IPC D06M14/22 C09K21/10 C09K21/12 C09K21/14 

FIELD: textiles, paper.

SUBSTANCE: treatment method includes the stage of emission treatment with irradiation of cellulose fiber material with irradiation, the stage of treatment with phosphorus with addition of phosphorus compound capable to radical polymerisation to the material of cellulose fibers, and the stage of treatment with amine with addition of amine compound to the material of cellulose fibers. The phosphorus compound capable to radical polymerisation is a vynil-phosphate compound. The amine compound is a polymer containing amino group, which is capable to form an ammonium ion in water. The cellulose fiber treated with this method is used to obtain fire-retarding material. In the fire-retarding material the cellulose fiber is connected with the phosphorus compound capable to radical polymerisation by the additive reaction, and the amine compound is bound with ion bond to the phosphorus compound combined and capable to radical polymerisation.

EFFECT: material has sufficient flame proofing and excellent tactile perception of the fabric.
