Research of fire resistance of textile materials treated with different flame retardants

Technological solution of the proposed research is based on the use of available raw materials, excludes the use of expensive reagents, high temperatures, pressure, special equipment. The article examines the flame retardant properties of textile materials treated with imported preparations: Nortex-X (cotton fabric), Nortex-KP (nonwoven fabric) and composition of guanidine hydrochloride and sodium phosphoric acid. Research objects: cotton fabric, nonwoven material from waste linen and wool fibers, as well as flame retardants and chemical preparations (NortexX (for cellulose fibers), Nortex-KP (for nonwoven material), guanidine hydrochloride and sodium phosphoric acid). During the research work, several complex research methods were used; combustion resistance of the material was determined in accordance with the requirements of GOST R 50810-95 standard. An scanning focused-beam electron microscope JSM-6490LA (Japan) was used to study the surface morphology of textile fibers. IR spectroscopic analysis was performed using a Spectrum 65 FTIR spectrometer (Perkin&Elmer). As a result of the study it was found that textile materials treated with a composition based on guanidine hydrochloride and sodium phosphoric acid acquire high flame retardant properties. Nonwoven fabric treated with Nortex shows improved flame retardant properties. However, cotton fabric treated with this preparation does not have flame retardant properties.
