Flame-retardant fabric is used for the inner lining of high-speed train seats to address fire safety issues in the carriage.

Pre-oxidized fiber woven fabric

1. Excellent flame retardancy and fire resistance:

It does not burn, melt, or drip when exposed to an open flame; it self-extinguishes after removal from the flame. The limiting oxygen index is typically as high as 55% or more, classifying it as a flame-retardant material.

Under high-temperature flames, it can maintain structural integrity for a long time, directly carbonizing to form an effective heat insulation barrier.

2. Excellent high-temperature resistance:

It can be used for extended periods at temperatures of 200-250°C.

It can withstand short-term, instantaneous high-temperature shocks of 500-600°C or even higher (such as welding sparks, molten metal splashes).

It does not soften or melt at high temperatures and exhibits good dimensional stability.

3. Good thermal insulation:

It has a relatively low thermal conductivity and can effectively insulate against heat transfer, protecting people or equipment from high-temperature damage.

4. Good chemical stability:

It is resistant to corrosion from most acids, alkalis, and organic solvents (except strong oxidizing acids), making it suitable for applications in corrosive environments such as chemical plants. [The above data is from online sources and laboratory tests]

5. Certain mechanical strength and wear resistance:

Its strength is higher than that of ordinary textiles; it has good wear resistance and tear resistance, resulting in a longer service life.

It is softer than carbon fiber cloth and is easy to cut, sew, and process into various shapes.

6. Low smoke and non-toxic:

At high temperatures or during combustion, it releases very little smoke and does not produce toxic gases, meeting stringent environmental and safety requirements.

7. Good conductivity (relative to ordinary fabrics):

Pre-oxidized fibers have a certain degree of conductivity (between ordinary fibers and carbon fibers), giving them anti-static properties and making them advantageous in situations requiring electrostatic protection. However, this also means it is not an insulating material.

8. Good dimensional stability:

It has a very low shrinkage rate in high-temperature environments and maintains a stable shape and size.

Application areas:

Personal protective equipment:

Firefighting suits: As a key material for the flame-retardant and heat-insulating layer, it protects firefighters from flames, high temperatures, and thermal radiation.

Industrial protective clothing: Welding suits, furnace worker uniforms, foundry worker uniforms, petrochemical worker uniforms, etc., protecting against welding sparks, molten metal splashes, high-temperature radiation, and hot surface contact.

Racing suits/racing car interiors: Areas with very high fire and flame retardant requirements.

Police uniforms: Used in special combat uniforms with fire and explosion protection requirements.

Industrial thermal protection and insulation:

Welding blankets/fire blankets: Covering the welding area to prevent sparks from igniting surrounding items or protecting precision equipment.

High-temperature pipe/equipment insulation layer/wrapping material: Reducing heat loss or preventing personnel from being scalded.

Kiln/oven curtains, sealing materials: High-temperature resistant, heat-insulating.

Molten metal protective curtains/baffles: Protecting against splashing molten metal in the foundry and metallurgical industries.

Engine compartment insulation: Fire, sound, and heat insulation for automobile, ship, and aircraft engine compartments.

Fire curtains/fire door core materials: Used for fire separation in buildings.

Aerospace and transportation:

Fire-resistant seat covers, wall panels, curtains, and carpet backing in aircraft, high-speed rail, and ships.

Fire-retardant and heat-insulating materials around engines.

Fire safety and emergency response:

Escape blankets (lighter than ordinary fire blankets).

Fire-resistant coverings for important equipment and artifacts.

Fire-resistant tents and fire-resistant storage materials.

Filter materials:

Used in high-temperature dust filter bags (such as coal-fired boilers, garbage incinerators, and cement plants), they are high-temperature resistant, corrosion-resistant, and flame-retardant.
