FIELD: textile industry.
SUBSTANCE: invention relates to technology of manufacturing flame retarded textile materials, which may be used as filler when manufacturing flame retarded composites and decorative and finishing textile materials. Method of invention comprises applying burning retardant, namely Antipyrene T-2 (methylphosphonamide ammonium salt) onto polycaproamide or polyethylene terephthalate fiber, retardant being used in the form of 5-7% aqueous solution. Fiber is the additionally exposed for 25-30 sec to 350 W CO2-laser emission. Treated fiber contains 22-25% Antipyrene T-2 and is characterized by oxygen index: 35% (polycaproamide) and 42.5% (polyester fiber). Strength of fibers is slightly increased.
EFFECT: substantially increased fire resistance of textiles.
