Investigations were made of the thermal stability of polyamide yarns modified with epoxy compositions. Single-walled carbon nanotubes «TUBALL Nanotubes» were deposited in epoxy compositions, astral and carbon. The analysis of the thermogravimetric characteristics of the samples is carried out (the temperature of the onset of thermal destruction and ignition of the substance, the thermal effect of the combustion reaction). Using atomic force microscopy, the structure of modifiers was studied. The results of the experiments confirm the possibility of using modified polyamide fibers due to their improved heat resistance indicators of firefighters protective clothing under conditions of hydrocarbon combustion.
