COMPOSITION FOR FIRE-PROOF FINISHING OF POLYACRYLONITRILE FIBRES Russian patent published in 2015 - IPC D06M15/673 D06M101/28 C09K21/12

Abstract RU 2565185 C2

FIELD: chemistry.

SUBSTANCE: composition for fireproof finishing of polyacrylonitrile fibre includes phosphorus-containing compound and water. As phosphorus-containing compound composition contains (wt %) phosphorus-, nitrogen-, chlorine-containing compound diammoniumchloride salt of diamidomethylphosphonic acid (7.5-15.0), additionally contain phosphorus-, nitrogen-containing compound N-methylol (O,O-dimethylphosphopropioamide (7.5-15.0) and urea (2.0-3.5) and water (the remaining part). Urea is used to fix fireproof composition components in fibre structure and to increase fireproof effect after wet processing.

EFFECT: invention makes it possible to reduce combustibility of polyacrylonitrile fibre to satisfy increased fire resistance requirements to manufacturing of textile materials.
