Fire protection clothing consists of outer layer, waterproof and breathable layer, thermal insulation layer and comfort layer. Among them, the outer fabric has high flame retardant and thermal protection properties, and is resistant to fire and high temperature; The waterproof and breathable layer is located between the outer layer and the insulation layer, which plays the role of preventing water from infiltrating into the insulation layer and discharging water vapor at the same time; The heat insulation layer has the function of high temperature resistance and heat insulation to protect firefighters from high temperature and radiant heat; The main function of comfort layer is to make firemen more comfortable to wear.

The multi-layer structure makes the fire protection suit www.dehsm.com/goods-1555.html have better flame retardancy, heat insulation and radiation heat penetration resistance, but at the same time, the air permeability of the fire protection suit will be weakened, and with the increase of the weight of the fire protection suit, firefighters will generate more bio-heat. This extra heat makes the body temperature rise, which has an impact on the health of firefighters.
