A systematic investigation of structurally identical flame retardant viscose, modal and polyester blended fabrics and fibres was carried out in order to develop a chemical basis for more effective products based on organic and inorganic flame retardants. The oxygen indices and chemical compositions of phosphorus‐nitrogen flame retardants (P‐N) were used in efficiency and synergy evaluations. A new flame retardant viscose fibre containing silicid acid was included in the comparative evaluation procedure. Thermal gravimetry and X‐ray diffractometry were used for determine physical factors during pyrolyzing of fibres. Charred residues were analyzed by applying elementary and solid 13‐C NMR (CPMAS) spectrometry. The pyrolysis gas‐liquid chromatographer connected with a gas phase FT infrared spectrometer was applied to identify the decomposition products of P‐N‐containing fabrics.
