METAL APPLIED FABRIC FOR COVER OF THERMAL INSULATING AND HEAT REFLECTING SUIT Russian patent published in 1996 - IPC

FIELD: gas and oil extraction industry, to make cover of thermal insulating and heat reflecting suit for gas and oil fountain fighting workers in particular. SUBSTANCE: fabric has complex warp and filling threads based on aromatic polyamides and has metal applied film fixed by glue doubling method on right side. Fabric density on wrap and filling threads is 16 - 25 and 14 - 20 threads per 1 cm correspondingly. Void factor of weave is equal to 0.54 - 1. Supporting surface of fabric under specific pressure of 1 kg/cm on sample is 6.2 - 17 %. Complex threads have diameter of 0.15 - 0.40 cm and are twisted between each other with step of 1 - 3 flights/cm. EFFECT: fabric allows to increase tensile strength and resistance to impact, bending stability, durability, to decrease lengthening during during break, rigidity and tangential resistance factor. 2 cl, 2 tbl
