Promising Nonwoven Materials Based on Heat-Resistant Fibers for Thermal Protection

The physical, mechanical, and thermal properties of new nonwoven materials based on heat-resistant fibers were studied. An analysis of existing nonwoven materials of various fibrous compositions, as well as effective water-repellent compositions, was carried out. A technique has been developed for the production of hydrophobized nonwoven materials using solutions of fluorine-containing latex. Bulk density values of samples were determined, thermogravimetric analysis was carried out, mechanical properties (values of breaking load and elongation at break), water absorption, and other technical characteristics of the developed material were studied, and an experimental batch was manufactured.
