PROTECTIVE SHIELDING THERMORESISTANT FABRIC Russian patent published in 2018 - IPC D03D15/00 A41D31/00 

FIELD: individual protection means.

SUBSTANCE: proposed protective shielding fabric is designed to protect a person and technical equipment from the effects of such unfavorable factors as: thermal impact of the electric arc, electromagnetic field of industrial frequency, induced and step voltage, electromagnetic field of the radio frequency range, as well as the effect of an open flame (human) and the electromagnetic field of the industrial frequency. In protective shielding fabric, containing yarn of aramid and metal fibers, the yarn is made of a multicomponent of staple fibers, taken in the following relationship: 5–15 % – polyamide fiber, 20–41 % – aramid fiber, 44–70 % – metal fiber, the fabric structure consists of one weft and one main yarn. As aramid, meta-aramid, para-aramide or a mixture thereof is used. Metal fibers are made of stainless steel. They can be galvanized. Surface density of the yarn is in the range of 110–600 g/m². Fabric can be made of linen, twill, satin, warp satin or mixed weave. Size of staple fibers is 40–55 mm. Electrical resistance of the fabric is no more than 10 ohm.

EFFECT: fabric can be used for the manufacture of protection equipment for humans and equipment from the effects of unfavorable external factors.
