Background
The high-temperature and hot environment such as outdoor operation, fire fighting, armed police, sanitation workers, mine, underground operation and the like greatly affects the human body, not only reduces the working efficiency, but also can bring long-term occupational hazards. For this reason, some cooling garments have been manufactured to be used in less than severe temperature change environments. For example, in the gulf war, army soldiers use cooling suits with liquid cooling coils and fans to combat the summer heat in the desert. However, such devices are cumbersome, consume a large amount of energy, and are inconvenient to move about after being worn.
Cooling garments exist which are made of phase change material, but such phase change cooling garments are inserted into pockets in the inner layer of the garment in a bag-like form which not only has poor flexibility but also greatly compromises comfort. Meanwhile, the air permeability of the cooling suit is affected, and the cooling suit does not have waterproofness. The outer layer of the temperature-reducing garment is not subjected to special functional treatment, and most of heat cannot be discharged outside the temperature-regulating garment. Therefore, a novel phase-change composite fabric and temperature-regulating clothes are provided.
