1. Thermal radiation protection fabric: This type of fabric is mainly used in high-temperature radiation environments. The fabric is required to have a strong reflective clothing that can better reflect radiant heat. Generally, a metal film is coated on the surface of the fabric. It is selected for excellent melting at high temperatures , Interference, interference, fiber such as aramid, glass fiber and carbon fiber.
2. Protective fabric that is resistant to melting and splashing: the degree of casting and contact with molten metal from the metal processing plant next to the high-protection pouring station is as high as 650-1565 (. Living in this environment Ip. The fabric is required to be resistant to melting. Function. 3. Thermal insulation fabric: In some special occasions, people must be in contact with hot objects. In order to avoid burns and scalds caused by fi conduction, fabrics are required to have good thermal insulation properties.
4. Fireproof fabric: The protective clothing worn by firefighters requires Sichuan fireproof fabric. Therefore, the fabric is required to have good solar radiation and thermal insulation. The fabric used should have resistance and resistance to fusion. To avoid injury.
“Two) Principles of Thermal Protective Fabrics
1. Heat When there is temperature A inside the solid, the hot seam will transfer from high overflow to low temperature. The thermal site transferred by the unit is directly proportional to the thermal conductivity. The smaller the thermal conductivity, the smaller the thermal conductivity of the material. The purpose of thermal protection can be achieved.
2. Reflection According to the radiation mechanism, if the reflection coefficient of an object irradiates the hot spot of the object, it will all be reflected back. In order to improve the reflection of the fabric surface.
3. Increase the breathability of the fabric. In high temperature environments, it is easy to accumulate heat sites in the fabric and body surface. If the fabric’s breathability is not good, it will affect the comfort of wearing when the heat is severe. sex.
