CLOTHES FOR RESCUERS OPERATING UNDER EXTREME, SEISMICALLY DANGEROUS CONDITIONS COMBINED WITH RADIOACTIVE EMISSION

摘要

FIELD: personal use articles.;SUBSTANCE: clothes for rescuers operating under extreme, seismically dangerous conditions combined with radioactive emission consist of a jacket for protection against mechanical impacts, a bib overall, a vest and a rescuer headpiece. The protective jacket has a protective shell consists of a textile lining connected to the protective shells; fixed in the textile lining by means of belt fixtures are resilient framework posts with the protective shells mounted on the resilient framework posts; the protective shell consists of three layers; the first layer turned towards the environment surrounding the operator is designed in the form of interconnected rings made of stainless steel while the third layer turned towards the operator body is made of a perforated polymer material such as aramid fibre; the second layer positioned in between is made resilient, composed of ferromagnetic textile containing a base, a binding polymer substance and a ferromagnetic material powder. The textile base is woven by plain weave with warp and filling filaments alternatively represented by lavsan filaments and magnetically soft monofilaments, the number of filaments per 1 m equal to 5000÷7000; magnetically soft monofilaments arte made of supermalloy or molybdenum permalloy with cross section size equal to 0.05÷0.1 mm; lavsan filaments have linear density equal to 10÷20 tex; the ferromagnetic powder is represented by high-coercitivity alloy powder. The ration of components in the textile (wt %) is as follows: lavsan filaments - 10÷15; magnetically soft monofilaments - 20÷25; binding polymer material (acryl copolymers) - 10÷15; high-coercitivity alloy powder - 50÷55.;EFFECT: increased efficiency of protection under extreme, seismically dangerous conditions combined with radioactive emission by way of application of a ferromagnetic material with improved indices of radioactive emission absorption and scattering and increased strength.;8 dwg
