The paper studies the effect of high and low temperatures on the mechanical properties of fabrics, produced from Rusar threads. The mathematical models can predict the mechanical properties, depending on the duration of exposure to temperature and its size.

The paper studies the mechanical properties of fabrics from Rusar threads in dry and wet condition, as well as the number of layers. The authors describe methods for determining the puncture resistance, cutting and punching, defined breaking load and elongation at break, resistance to puncturing, cutting and punching fabric from Rusar threads, when tested in one and several layers of dry and wet.

The paper assesses the quality of fire-resistant fabrics for special clothing welders, describes new and improved existing methods for determining fire resistance and tissue resistance to sparks and molten metal splashes. The results of the tests give expert evaluation of the suitability of investigated fabrics for clothing welders.
