Flame Retardant Fabric
- Apr 09, 2018 -

The first thing you should know about fire retardant fabrics is that there are two main types: Inherently or Chemically Treated.

Let's take a look at . Before we get started, it’s important to note that no fabric is actually fireproof; given enough time, they will burn. That being said, there are some fabrics out there that resist fire more than others. For example, we all know that cotton burns easily and rapidly. However, fabrics like wool and Kevlar resist flames inherently because of the structure of the fiber. A tightly woven wool fabric will take longer to burn than cotton or linen. 


A fabric is categorized as inherently fire resistant fabrics if woven with threads that yield a product that meets fire code standards, without being subject to any special processing or addition of chemicals.Inherently fire resistant fabrics fabrics are expected to remain flame retardant for their lifetime, even after repeated washings. The “inherently flame retardant” phrase has been used in this manner for nearly a century now.

Permanently Flame Retardant Fabrics vs. Treated Flame Retardant Fabrics

The good news is that the flammability of fabric can be drastically reduced through the use of fire retardants. Many natural fibers, including cotton, can be topically treated with a chemical that reduces the fabric’s flammability to the extent that it becomes nearly non-combustible. During a fire, the chemical reacts with the gases and tars generated naturally by the fabric, converting the gases and tars to carbon char, thus drastically slowing the fabric’s burning rate.


Some polyester fabrics are considered permanently flame retardant.
