The article deals with Justification for the design of protective clothing against cold, the main means of calculation and design assessment which is mathematical modeling. Justification of pilot studies of influence of parameters of a matrix of fixing of the special soft polymeric edges forming the additional locally concentrated rigidity of external material of the warmed clothes of a special purpose is presented in article. Technical characteristics and standard restrictions for the textile material considered at the heart of the projected product taking into account the requirement of GOST and operational criteria are given. Data on modern ways of increase in resistance of an external cover of clothes to the deforming influences for the purpose of preservation of internal volume and, as a result, necessary thermal insulation of clothes are submitted. On the basis of established experimentally dependences of rigidity of the modified material on width and thickness of polymeric channels the way identification of extreme density of filling of polymers of the internal surface of integumentary material with it taking into account the requirement of hygienic and operational character is offered.
