Thermal
comfort is one of the most important parameters of comfort that shows the
satisfaction of the physiological, psychological, and physical harmony between
the human body and the environment. Thermal comfort is related to the heat and
moisture permeability properties of clothing. The warming properties of
clothes, in other words, the thermal resistance values of the fabrics, can be
made by numerous variations in fabric construction. However, the fabrics
produced that can be produced to make the person feel cool are much more
limited. Among these, thin fabric production by using cool-feeling yarns is the
most widely applied one. This study aims to design, produce and examine the
performance of knitted fabrics that provide active cooling using a
thermoelectric module. A vest was chosen as the garment in which the cooling process
would be carried out. 1x1 rib, ottoman, tubular, and plain knit structures were
used locally in fabric production. During the production of the back part of
the vest, a silicone hose was placed in the gaps of the ottoman knit structure.
The thermoelectric module was used as a cooling unit. An aluminium water/liquid
cooling block was placed on the cooling side of the thermoelectric module, and
the water was circulated using a dc pump motor. The cooling surface temperature
was controlled with the thermostat circuit, and the system was enabled to
operate within the desired temperature range. Thermal camera measurements
revealed that the garment's temperature decreased from 41,0oC to
21,6oC within 20 minutes. It can be concluded that knitted garments
can provide active cooling using thermoelectric modules and auxiliary
equipment.
