Results are presented from a study on the prediction of the insulation abilities of outerwear clothing for cold protection from the point of view of the thermophysiological comfort of the wearer. The Required Clothing Insulation (IREQ) index is used to simulate the abilities of 14 assemblies of layers designed for the production of winter jackets to protect the body in different cold environments. The calculations allow to assess the limits of applicability of the garments in terms of the thermophysiological comfort assured, the activities performed and the weather conditions. Discussions are presented on the correspondence between ISO11079:2007 and the online JavaScript code for calculation of IREQ based on it. The results predicted and their analysis have a practical use, as they allow to estimate the cold protection effectiveness of the textile layers used in an assembly at the design stage, thusgiving room for necessary changes depending on the conditions of its use.

Wykorzystano wskaźnik IREQ (required clothing insulation – wymagana ciepłochronność odzieży) do symulacji zdolności termicznej 14 zestawów warstw przeznaczonych do produkcji kurtek zimowych chroniących organizm w niskich temperaturach. Obliczenia te pozwalają ocenić ograniczenia zastosowania odzieży przy założeniu wymaganego komfortu termofizjologicznego, przy określonej aktywności użytkowników i w danych warunkach pogodowych. Uzyskane wyniki badań skorelowano z obowiązującymi normami. Wyniki badań mają praktyczne zastosowanie, gdyż pozwalają ocenić skuteczność ochrony przed zimnem danych zestawów warstw tekstylnych na etapie projektowania ubioru, przed sprawdzeniem gotowego wyrobu w praktyce.
