Let’s take a look at inherently fire-resistant fabrics. Before we start, it’s important to note that no fabric is fireproof; given enough time, it will burn. That being said, some materials out there resist fire more than others. For example, we all know that cotton burns easily and rapidly. However, wool and Kevlar inherently resist flames because of the fiber's structure. A tightly woven wool fabric will take longer to burn than cotton or linen.
Inherent vs. Treated
The first thing you should know about fire retardant fabrics is that there are two main types: Inherently or Chemically Treated. A fabric is inherently or chemically flame retardant, which matters when it comes to what you’re using the fabric for and how long you want it to last. Over time you can wash out chemicals, but if you take care of your fabric, it can last a long time. Remember, some fabrics are naturally more resistant to catching fire than others. Like tightly woven wool takes longer to burn than cotton.
Inherently fire-retardant fabrics are excellent for use in your home, especially for things like curtains and drapes. (This is one way to protect your home and family from fire and chemically treated materials). These fabrics can also be used in tents, health care fabrics, drapes, tarps, military applications, awnings, banners, and signs.
Finding the proper manufacturer for your fire retardant project/product is essential, especially when considering chemically treated fire retardant fabrics. That’s why Herculite Inc. offers customers a variety of products that are not only fire retardant but meets the National Fire Protection Association standards.
The NFPA is the world’s leading advocate of fire prevention and an authoritative source on public safety; NFPA develops, publishes, and disseminates more than 300 consensus codes and standards.
The application of flame-retardant fabrics is far-reaching. For example, Herculite Inc. offers the Sure-Chek® high-performance fire barrier fabric. The Sure-Chek® fire barrier fabric is flame resistant and self-extinguishes when removing a source flame. These products are manufactured and tested by accepted industry standards.

What are some of the significant testing standards for flame-retardant textiles?
Flame standards for textiles refer to regulations and testing methods that determine the flammability characteristics of textile materials. These standards assess the fabric's resistance to ignition, flame spread, and other fire-related behaviors. Compliance with flame standards ensures that textiles meet specific safety requirements and reduce the risk of fire hazards. Here are some commonly used flame standards for materials:
- NFPA 701: The National Fire Protection Association (NFPA) 701 is a widely recognized standard in the United States for flame propagation of textiles and films. It addresses the fire behavior of fabrics used in curtains, draperies, and similar applications. The test evaluates the fabric's response to a small-scale flame and measures parameters such as ignition time, flame spread, and after-flame duration.
- ISO : This International Organization for Standardization (ISO) standard is known as the "vertical flame test" or "vertical strip test." It assesses the flame resistance of textiles when exposed to a small flame applied vertically. It measures after-flame, after-glow, and damage length to determine the fabric's performance.
- BS : The British Standard is a flame-retardant test method used in the United Kingdom. It assesses the ignition resistance of upholstery materials used in furniture, including fabrics, foams, and fillings. Part 1 covers ignition sources for a cigarette and match flames, while Part 2 addresses using a gas flame as an ignition source.
- DIN : The German standard DIN evaluates the fire behavior of materials, including textiles. Multiple classifications, such as B1, B2, and B3, indicate different flammability levels. B1 is the highest level, meaning a material that is difficult to ignite and has limited flame spread.
- AS/NZS : The Australian/New Zealand Standard assesses the fire performance of building materials, including textiles. It comprises two parts: Part 2 measures the flammability properties, such as ignition time, flame spread, and heat release rate, while Part 3 evaluates the spread of flame on external walls.
These are just a few examples of flame standards for textiles. Different countries may have national or regional standards that manufacturers and suppliers must comply with to ensure the safety of textile products. It is essential to consult the relevant standards and regulations applicable to your specific region or intended market to make sure it is in compliance.
So what have chemically treated fire retardant fabrics?
Well, they are fabrics that have been coated with a fire-resistant chemical. Today, there are more than 175 different types of flame retardants, according to the International Association of Certified Home Inspectors (InterNACHI). These chemical types are brominated, chlorinated, phosphorus-containing, nitrogen-containing, and inorganic flame retardants. Flame retardant chemicals are also known as PBDEs or polybrominated diphenyl ethers.
Keep in mind that PBDEs are chemical, and you might have questions about their safety. Visit the Center for Disease Control’s Agency for Toxic Substances and Disease Registry’s Web site for more information at: http://www.atsdr.cdc.gov/toxfaqs/tf.asp?id=900&tid=183.
If you buy a treated fabric, remember that the chemical starts to wear down as you wash and use it. Inherently fire retardant fabrics don’t suffer from this issue. You may also consider that adding an FR treatment to a material may void the manufacturer's warranty.
