PROTECTIVE JACKET Russian patent published in 2015 - IPC A41D13/00 

FIELD: personal use articles.

SUBSTANCE: protective jacket 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 resilient mesh elements. The density of the mesh structure of the resilient mesh elements is within the optimal range of 1.2 g/cm³…2.0 g/cm³; the resilient mesh elements wire is made of Grade EI-708 steel, such wire diameter varying with the optimal range of values from 0.09 mm to 15 mm; the jacket top fabric is represented by a fibrous textile material with bioprotective qualities based on natural or chemical fibre including biologically active polyester fibre produced by way of fibre modification in the process of crazing, with linear density equal to at least 0.33 tex while linear density of the natural or chemical fibre is 0.33÷0.51 of the latter's linear density, the components ratio (wt %) being as follows: natural of chemical fibre - 70÷95, biologically active polyester fibre - 5÷30. The material absorbing radioactive emission is represented by material containing a filler represented by lead oxides (lead II, IV oxide) and a binding agent represented by polyvinylbutyral, ethyl acetate, di-(alkylpolyethyleneglycol) phosphate ester of the formula where n=6, R - alkyl group containing 8-10 carbon atom and ethylcellulose at the following components ratio, wt %: lead II, IV oxide - 30.6-56.8, polyvinylbutyral - 3.8-10.2, ethyl acetate - 14.3-26.5, di-(alkylpolyethyleneglycol) phosphate ester - 0.2-0.4, ethylcellulose - balance; the new composition of the binding agent ensures complete compatibility with lead oxides and allows to obtain materials with a high lead equivalent and flexibility degree; the material has good adhesion to metals, concrete and bricks; the material is represented by highly concentrated suspension quickly hardening in the air; the material viscosity is 20-70 Pa·s which renders it suitable for casting varied thickness films with the help of a die or extruder, application onto surfaces with a brush, pouring over or pouring into different cavities, cracks and channels.

EFFECT: enhanced effectiveness of operator protection against mechanical impacts.
