Abstract: The course of ''Comfort and function of clothing and leather products'' delivered at Faculty of Textiles, Leather and Industrial Management, is dealing with the thermo-functional design of the clothing, which is a complex approach. The paper proposes a software application, the use of which facilitates the thermo-functional design of the clothing and can be exploit as a tool in teaching activity, as well in research activities (http://www.moodle.tex.tuiasi.ro). For the calculations, two groups of factors were taken into account: factors related to the destination (environmental factors and the state of the body) and factors related to the textile materials that are part of the analyzed clothing. The two groups of factors are synthesized in two thermo physiological indicators: the total heat transfer coefficient imposed by Kimp [Kcal/m2hoC] and the total heat transfer coefficient calculated on the basis of the Kcalc [Kcal/m2hoC] textile materials. A clothing product is considered thermo-functional when the Kimps - Kcalc difference is lower or the ideal case when the two indices have equal values. The calculations follow algorithms specific to the field of thermo physiological comfort and require high work and time. Two options are available for the users after opening the application, envisaging the two mentioned indicators. The application is conceived with the possibility of memorizing the working steps, as well as with the possibility of modifying them. Another advantage of the application is that starting from the knowledge of certain values of the textile materials characteristics, the thermo- physiological evaluation of the product clothing can be achieved.
