Background

A person has his own isothermal zone where it can maintain its normal body temperature by physical adjustments. If the ambient temperature continues to rise, the heat dissipation capacity of the person is hindered and the thermal equilibrium cannot be maintained by physical regulation alone, at which point physicochemical regulation must be initiated. When none of these regulations is effective in maintaining the heat balance in the body, there is an abnormal change in the physiological functions of the human body, particularly the functions of thermoregulation, water and salt metabolism, blood circulation, etc. For example, a large amount of perspiration can put a heavy cardiovascular burden. If the high temperature exceeds the tolerance of human body, the work efficiency is reduced if the high temperature is low, the judgment is influenced, sunstroke can be caused if the high temperature is serious, sudden death can be caused if the high temperature is serious, and the cooling and cold accumulation protective clothing is suitable for transportation to solve the problems.

Most phase transition cooling clothes on the market all are through cold glue or phase change material as the cold source, inject this kind of material into or insert the protective clothing, can keep the cold volume for a certain time after freezing the protective clothing, but the biggest shortcoming of existence is exactly that the gel can harden after freezing, do not laminate the people's health, flexibility when seriously influencing the wearer action, simultaneously because of the temperature difference at the condensate water of material surface production and because of the poor human sweat that produces of dress gas permeability, the travelling comfort when seriously influencing the people and wearing.

To sum up, an urgent need exists for a cooling garment with good air permeability and wearable flexible phase change material, which can greatly improve the working efficiency of a wearer while enhancing the comfort of the wearer.
