METHOD FOR PRODUCTION OF FIRE-RETARDANT POLYESTER FIBROUS MATERIAL Russian patent published in 2006 - IPC D06M13/288 D06M10/08 C09K21/12 D06M101/32

Abstract RU 2281992 C1

FIELD: fire-retardant ornamental textile materials, fillers for fire retardant composites.

SUBSTANCE: claimed method includes burn retardant into polyester fiber. As burn retardant 5-7 % dimethyl phosphonate aqueous solution is used. Additionally material is treated with CO₂-laser irradiation with power of 350 W, density of 5.3 W/cm, for 25-30 s up to dimethyl phosphonate content on fiber of 12-15 mass %. Fibers are characterized with oxygen index of 31.5-33 %, and fiber durability is narrow increased.

EFFECT: new flame-retardant materials.
