Do you know about flame retardant fabrics?

Fire-resistant fabrics, as a type of textile material with special protective properties, can effectively suppress combustion when exposed to flame, slow down the spread of fire, or quickly self-extinguish after leaving the fire source. They are widely used in a variety of applications that have stringent fire safety requirements.Required FieldsBased on various manufacturing processes, flame retardant mechanisms, and application scenarios, flame retardant fabrics can be broadly classified into three categories: modified fibers, chemical finishing, and composites.

1. Fire resistant fiber modified fabrics.

This type of fabric provides a fire retardant effect mainly by changing the structure or composition of the fiber itself. For example, polymer compounds containing fire-retardant elements such as phosphorus, nitrogen and silicon are used to synthesize new fire-retardant fibers such as aramid (Nomex), polyphenylene isophthalamide (PBI), etc. These modified fibers burn difficult even at high temperatures and have good thermal stability, are able to maintain structural integrity for a long time and prevent leakage of the melt due to the ignition of other substances. Fire-resistant fiber-modified fabrics are often used in firefighter suits, flight suits, racing suits and other applications where an extremely high level of protection is required.

2. Fire-resistant fabrics with chemical treatment.

Chemically treated flame retardant fabrics are made by post-treating conventional fabrics, that is, using flame retardants to line, coat or spray their surfaces so that the fabrics can acquire temporary or semi-permanent flame retardant properties. Commonly used flame retardants include inorganic flame retardants (such as phosphates, aluminum hydroxide, etc.) and organic flame retardants (such as halogen, phosphorus, nitrogen, etc.). The finished fabric can form a heat-insulating protective layer during the combustion process, absorb heat, release inert gas, and dilute the concentration of combustible gas, thereby achieving the purpose of fire resistance. This type of fabric has a relatively low cost and is suitable for industrial protective clothing, hotel curtains, theater curtains, home decoration fabrics and other uses.

3. Composite fire-resistant fabrics.

Composite flame retardant fabrics combine the above two methods, including modified flame retardant fibers and chemical finishing treatment, to obtain better flame retardant effects as well as washability and durability. For example, blending flame retardant polyester with cotton and adding a flame retardant finish not only brings out the long-term flame retardant properties of polyester, but also maintains the comfort of cotton fabrics. It is suitable for making high-strength fabrics. -ultimate workwear, military equipment, ship interiors, etc.

Fire-resistant fabrics are widely used:

1. Fire safety: Firefighter protective clothing, rescue ropes, fire blankets and other products should be made of high-performance flame-retardant fabrics to ensure the safety of personnel in fire conditions.

2. Military and national defense: Military tents, camouflage uniforms, pilot uniforms, ship interiors, etc. must have fire-retardant properties to prevent secondary damage caused by fire sources during combat.

3. Industrial production area. For workwear in industries such as electrical power, chemicals, metallurgy and petroleum, as well as for personal protective equipment such as miner's hats and welding gloves, the use of flame retardant fabrics can effectively reduce the risk. professional fires.

4. Transport sector. The use of fire-resistant fabrics in aircraft, train and automobile interior materials such as seat covers, carpets, curtains, etc. can help improve fire safety standards in transportation.

5. In the field of architectural decoration: the use of fire-resistant fabrics for soft upholstery materials such as curtains, wall coverings and ceilings in public places such as hotels, theaters, schools and hospitals can help improve the overall level of fire protection. and follow fire safety regulations.

6. Home life: Children's pajamas, bedding, kitchen utensils and other household items are made of flame retardant fabrics, which can become a fire barrier in daily life.

To summarize, flame retardant fabrics play a vital protective role in many applications due to their unique flame retardant properties. With the development of science and technology and the diversification of market demand, future research and development of flame retardant fabrics will pay more attention to the combination of environmental protection, comfort and multi-functionality to meet the individual protection needs of various industries and industries. environment.
