A brief analysis of the performance characteristics of thermal insulation clothing.
2022-02-14
Heat-resistant clothingAlso known as thermal protective clothing, it is an important personal protective equipment that ignites itself upon contact with flames and hot objects, preventing flame combustion and smoldering. It is divided into protective clothing that protects the human body from various injuries, protective clothing used in high-temperature furnace operations in industries such as petroleum, chemical, metallurgy, and glass, and firefighting clothing used for fire fighting and forest fire prevention.
FireproofHeat-resistant clothingComposed of multiple layers of fabrics including an outer layer, insulation layer, and comfort layer. The materials of these combined components can be made into single-layer or multi-layer. The outer layer should use metal aluminum foil surface materials that reflect radiant heat, meeting the technical requirements for basic garment production and the performance requirements of corresponding standard attachments.
Heat-resistant clothingAs personal protective equipment, it is receiving increasing attention from the safety protection industry in various countries around the world. SoHeat-resistant clothingWhat performance should it have?
1. Flame retardant performance
Flame retardancy refers to the difficulty of burning or not burning when the fabric encounters particularly high temperatures or flames. When the fabric catches fire, it can prevent the spread of flames, and once the fire source is removed, it can extinguish itself immediately. The most serious incidents in a fire often occur at the parts of people's clothing that catch fire, soHeat-resistant clothingthe flame retardancy is very important. InHeat-resistant clothingthe usage process, one side of the fabric usually faces the flames. For example, in firefighting work, the outer part of most firefighting clothing directly contacts flames, while the inside rarely contacts flames. Therefore, it is required that the heat-resistant fabric can resist flames from one side to the other, and the flame penetration performance of the fabric needs to be considered.
2. Heat resistance
In a fire, the temperature can rise to 600 degrees within minutes. In a room that is directly on fire, the temperature is also around 300 degrees, and high temperatures that can melt plastic can cause harm.Heat-resistant clothingIt is mainly used for high-temperature operations, and it must maintain its various physical properties under high temperatures without shrinking, melting, or becoming brittle.
3. Comfort
Heat-resistant clothingIn addition to having thermal protection performance, it should also have certain tensile strength, tear strength, abrasion resistance, and other excellent wearing performance and comfort. The dyeing should be firm and washable, and it should have a certain thermal moisture transfer ability to assist in heat loss and sweat evaporation, with low physiological load, lightweight, easy to wear, loose structure, not easy to snag, and reinforced measures for easily injured areas, meeting the requirements for coordination and comfort, thereby improving work efficiency.
4. Insulation
InHeat-resistant clothingactual use, most users do not directly contact flames, and external heat is transmitted to the human body through thermal convection, thermal radiation, and thermal conduction, causing harm to the body. Heat-resistant clothing must have good deceleration and heat transfer performance to prevent heat sources from causing damage to the human body and to provide good safety protection for users working in high-temperature environments.Heat-resistant clothingInsulation is related not only to the thermal conductivity of the fiber materials of the thermal protective clothing but also to the design of the clothing and the fabric of the clothing. The structure of the material lining is also significantly related.
