Flame retardant and thermal protective clothing should have the performance requirements

In general, flame retardant and heat insulation protective clothing must have the following properties.

1. Heat-resistant performance

Heat-insulating protective clothing is mainly used in high-temperature operations, and must maintain its own physical and mechanical properties at high temperatures, without shrinkage, melting and brittle carbonization.

2. Flame resistance

In the use of thermal protective clothing, generally one side of the fabric to meet the flame, such as firefighting uniforms, in the firefighters in and out of the fire operation process, to a large extent, the outer side of the firefighting suit directly contact the flame, while the inner side is rarely in contact with the flame, which requires thermal protective fabric with the ability to resist the flame from one side of the burn through to the other side of the performance, so you need to consider the fabric to the flame burn through performance.


3. Heat insulation

In the actual use of thermal protective clothing, most users do not directly contact the flame, but the external heat in the form of heat convection, heat radiation, heat transfer to the human body, causing harm to the human body. Thermal protective clothing must have a good performance of slowing and stopping the heat transfer, to avoid the heat source to cause harm to the human body, to provide good safety protection for users of thermal protective clothing working in high temperature environments.

4. Anti-liquid transmission performance

It refers to the performance of thermal protective clothing to prevent high-temperature water, oil, solvents or other liquids from passing through the fiber material of the clothing, the pores in the fabric, the seams of the clothing, and the pinholes. Thermal protective clothing anti-liquid transmission performance and clothing with fiber material properties, fabric structure and clothing structure.

5. Taking performance and wearing comfort

Thermal protective clothing in addition to thermal protection performance, but also must have good performance and wearing comfort, such as a certain tensile strength, tear strength, abrasion resistance, dyeing fastness and washability, but also should have a certain heat and moisture transfer capacity, in order to facilitate the dissipation of body heat and sweat evaporation, with a low physiological load.

In addition, thermal protective clothing also requires light quality, easy to put on and take off, loose structure, no restrictions on running, climbing, jumping and other movements, not easy to cause hooking, in the parts prone to injury to take strengthening measures to meet the requirements of coordination and comfort, and improve efficiency.
