HEAT RESISTANT FABRIC OF POLYMER FIBERS AND PRODUCTS MADE FROM THIS FABRIC Russian patent published in 2017 - IPC D02G3/04 D02G3/28 D03D15/12 D03D1/00 

FIELD: textile, paper.

SUBSTANCE: heat-resistant fabric is made by interlacing warp and weft yarns with a combined plain weave, with warp cord on the chain and with weft cord on the filling. The fabric is made of background warp on the chain and a mixed two-strand yarn consisting of equal parts of para-aramid fiber and polyoxadiazole 50×50 fiber. The resultant linear density of the fabric is 60 Tex. The fabric is reinforced on the chain and the filling by a double complex arimide thread 29.4 Tex × 2. The ratio of yarn to thread in the fabric is 75/25, and the surface density is 260 g/m². The fabric was further treated with at least one organofluorine preparation.

EFFECT: better combustion efficiency increased fire resistance, decreased stiffness and improved flexibility and draping characteristics in conditions of the Far North.
