The effect and principle of heat insulation clothing have a variety of pyrogen methods for the formation of adverse effects on the body, and the characteristics are not the same, so the fire-resistant function of heat insulation clothing is not the same. At this stage, the detailed methods of pyrogen include convection heat, touch heat, heat radiation, flames and welding metal materials gushing, high temperature vapor and hot vapor, high fever formed by electric arc, etc.

The heat insulation clothing is based on methods and methods to shield or weaken various heat conduction methods, thus completing the actual effect of heat insulation. Heat convection heat convection is accompanied by liquid (like water) or vapor (such as gas) and other liquid activities to transfer heat, liquid due to the uneven temperature of the liquid and exercise, so the method of transferring heat is called convection of course. There is of course convection between the body and the surface layer of the dress.
The thermal convection formed by the gas fitness movement formed by other external reasons is called mandatory convection. The heat-resistant convection characteristics of the fabric are closely related to the net weight, relative density and closed characteristics of the textile. Improving the quality of the fabric can delay the time it takes to cause a second degree burn. At the same time, the double-layer fabric has a stronger heat-resistant convection effect than the single-sided fabric.
Heat conduction means that the heat is transmitted along the object. Moving from high temperature objects to ultra-low temperature objects. This kind of relocation is mainly based on the continuous impact of the adjacent molecular structure center in the chemical substance. In the use of thermal protective clothing, heat conduction refers to the use of fire and welding metal material water jet as the preface, and clothing touch, according to the clothing will transfer heat to the body, and then cause damage to the body.
