SOL-GEL COMPOSITION ON THE BASIS OF SODIUM SILICATE AND AMMONIUM POLYPHOSPHATE FOR OBTAINING FIRE-RESISTANT CELLULOSE TEXTILE MATERIALS

Abstract

The article gives a new method for producing fire-resistant cellulose textile materials using the sol-gel method, where the sol-gel precursor is sodium silicate. A new sol-gel method is proposed for the formation on a fiber of a functional coating based on sodium silicate and nitrogen-phosphorus-containing compounds. The effect of processing parameters on the fire resistance and on the discontinuous characteristics of the obtained materials was studied. The method of scanning electron microscopy was used to study the structure of the surface of treated fibers. The thermal stability and index of the limiting oxygen index of control and processed cellulose textile materials with a sol-gel composition were studied.
