[Excerpt] In the present experimental research, the thermal insulation of an outdoor sports’ shirt was evaluated considering constant heat flux simulating exercise. The shirt was produced using a seamless weft knitting machine by combining different yarns and knitting structures in different parts of the shirt (Figure 1). The tests were conducted by a thermal manikin and the manikin regulation mode was chosen as constant heat flux (CHF) mode. The thermal manikin is divided in 20 thermally independent body sections. The tests were set according to “ISO 15831: Clothing - Physiological effects - Measurement of thermal insulation by means of a thermal manikin”. The manikin was slightly above the floor (0,10 m) in a standing position during the measurements. The dry heat flow from the manikin´s skin surface area through the clothing into the ambient air was measured. [...]
