The ability of a material not to change its properties when heated is an important characteristic of nonwoven and fibrous polymeric materials (VPM). The interaction of binder components, flax cellulose and non-cellulose impurities will largely determine their properties, including resistance to thermal oxidation. In this paper were used as objects of research cotton linen, samples of purified cellulose, extracted lignin, cotton fiber based on cotton linen, impregnated with polymer binders.
Enzyme-modified flax is obtained by effective fibration due to the selective hydrolysis of pectins and hemicelluloses, while structure-forming lignin has been preserved. The formation of VPM was performed by impregnation of undirected fibers located in the canvas with a binder based on 50% polyvinyl acetate emulsion and cyclic PA-6 oligomers (polymerization degree 6–11).
Fiber-polymer materials based on cottonin- flax with various types of binders were obtained, their thermal properties were studied on the Synchronous Thermal Analyzer – STA 449 F3 Jupiter®. Resistance to burning was evaluated according to standard 12.4.184. The effect of the introduction of natural aluminosilicates on the thermal properties of fibrous-polymeric materials has been studied.It was revealed that fibrous-polymeric materials with the inclusion aluminosilicate (from Malostupino) have low burnability.
