EDUCATION SOFTWARE FOR DETERMINING THE FUNCTIONAL THERMAL FIELD OF THE TEXTILE

Summary/Abstract: One of the most important issues that can be solved by using the numerical values of the thermo-physiological units (thermal resistance and resistance to the passage of the steam) is to establish the thermal field for using a textile product/apparel. The functional thermal field of a textile product/apparel is given by the variation range of the environmental temperature, situated between its minimum temperature tamax [oC] and the maximum temperature tamax [oC], when the wearer feels comfortable. This clearly indicates if the textile products/apparel corresponds to their scope of use. The scientific design of the textile materials/apparel aims for them to be functional in a wide range of environmental conditions and physical effort of the body, so that the wearer perceives them as comfortable. Then we can say that such textile material/apparel fulfills its thermal physiological function correlated to the requirements resulted from the field of use. The first part of this paper shows the theoretical calculation algorithm of the functional thermal field and a concrete example of determining it for 6 variants of layered jersey made of cotton and polypropylene, for sport, and the second part presents a software application for determining the functional thermal field. This software application has the role to simplify the workload and to reduce the time to determine the variation range of the thermal field, allowing the possibility to simulate, within a short time, the different situations referring to the condition of the body, the environmental conditions and the thermal and physiological characteristics of the analyzed textile materials.
