The article presents the data of the morphological study of textile materials based on cotton, flax and polyester, subjected to heat treatment. The morphological analysis of samples of fabrics made of cotton, flax and polyester was carried out, the dependence of the change in the structure of the fabric on the magnitude of the temperature effect was revealed. It has been shown that fabrics made of natural materials lose their color when heated, after which they partially carbonize with increasing temperature, and after reaching a temperature of 300 °C and above they begin to burn. It was found that a polyester fabric does not change when heated to 250 °C, and then begins to fusion, changing its structure.
