Heat equations such as heat flux and thermal conduction were applied in this paper so that these values were obtained during heat setting. Cotton spandex woven fabrics have the properties of stretch ability like stretch, growth, elasticity etc. Due to controlling such types of properties heat setting is mandatory. The values of heat flux and thermal conduction would be beneficial to heat application the fabrics more accurately. A heavy weight stretched woven fabric of twill weave was used in this research. The width of the fabric was 60 inch and had a thickness of 2.5 millimeter. Fabric was heated in a stenter machine with adjusted industrial settings. Heat flux values and thermal conduction values of the clothes were investigated using equations stated in this paper. Overheat can damage the fabrics drastically and all the comfort properties are also influenced seriously. Using heat flux equation and thermal conduction equation, fabrics are heated preciously and all these things are practically analyzed, examined and investigated in this research. This research is trial based and the findings are useful to the employees functioning in textile factories who are in duty of heat setting the cotton spandex woven fabrics and to controlling of their all comfort characteristics.
