NON-WOVEN FIRE RESISTANT PUNCHING MATERIAL

摘要

The utility model relates to the textile industry, namely, nonwoven needle-punched materials that can be used as personal protective equipment for work associated with increased thermal risks of an electric arc, as well as heat and flame, in particular for firefighter's combat clothing (FBO). Nonwoven flame retardant needle punched fabric for clothing contains 100% by weight of pre-oxidized polyacrylonitrile fibers. The specified material is made with a linear density of 0.17-0.19 tex, an areal density from 60 g / m2 to 300 g / m2 and a thickness from 2 mm to 8 mm. Needle punching of the material is made on one side from above with a piercing depth across the entire thickness of the material, and the density of needling is 200-250 bonding points per SMS with regular distribution of bonding points in the material relative to each other. The technical result is achieved - an increase in the total thermal resistance of the non-woven fire-resistant needle-punched material while maintaining its fire resistance. 1 dwg, 1 tbl
