Research on the design process and comfort optimisation path of functional clothing based on the principle of heat transfer

The function of heat and moisture transfer of garment fabrics plays a very important role in the regulation of microclimate inside the garment. The first step in improving clothing comfort research was to analyze the design needs of functional clothing based on the principle of heat transfer. Then, the functional garment test was proposed, six fabric fabrics were selected as experimental objects, and the thermal resistance value of fabrics in dry skin conditions and the total heat dissipation in sweaty and wet skin conditions were studied. At the same time, in 92% high humidity conditions, several common clothing fabrics made for human wearing experiments were assessed for their heat and humidity comfort in the high humidity environment. Finally, the optimisation of clothing fabrics, as an example of summer clothing, selected the maximum transient heat flux Q-max and selected the thermal conductivity K as a characterisation index to determine the optimal fabric organisation of the linen fabrics and cotton, and then On this basis, the design of summer garments is carried out. The main design of its loft and opening optimization has been carried out.
