Today, fire prevention is a national priority, particularly for companies that work closely with highly flammable materials. However, this concern is not limited to enterprises; at home, you may be surprised by the number of combustible materials surrounding you.
Fire safety precautions include identifying flame-retardant materials that can save your life and those flammable items that can hurt you. They can be anything from sofas to curtains, clothing, and furniture.
Polyester is the most extensively used fiber in the textile industry for various applications since it is a strong, durable, easy-to-dry, soft, and absorbent material. So it's likely that you'll encounter polyester in your house or business, but the question is: is polyester flame retardant?
At RDR Technologies, we want the best for our customers. That is why, in this edition of fire vs. materials, we will discuss polyester, its level of fire retardancy, and its treatment with fire retardant chemicals for added safety.
The Chemical Composition of Polyester
Polyester is a synthetic polymer made from polyethylene terephthalate (PET). This fabric is resistant to heat, shrinking, and mildew, so it is commonly used for garments.
We can find polyester in many items due to its versatility. It is used for clothing, furniture and upholstery, carpets and rugs, blankets, curtains and draperies, pillows, and many more.
The chemical composition of polyester is the cause of its flame retardancy, specifically due to two monomers: ethylene glycol and terephthalic acid.
These two monomers form the following structures - polyethylene terephthalate and polyester, a polymer containing both monomers.
The molecular structure is made up of individual strands of molecules that are tightly woven together.
The tightly woven structure also makes the fabric more resistant to heat, which is why it is often used for protection from heat and fire hazards.
Is Polyester Flame Retardant?
Many people who must deal with fire in their jobs question if polyester is flammable.
Polyester is considered one of the most flame-retardant materials available on the market because it is not inherently incendiary, meaning that it is difficult to ignite and is unlikely to catch fire.
When exposed to flame, the fabric does not burn easily. Instead, it chars and melts slowly.
The flame-retardant polyester fabric is not fireproof but provides an additional layer of protection. In addition to its flame-retardant properties, polyester is also resistant to chemicals and is strong enough to withstand wear and tear.
The Importance of Treating Fabrics With Fire Retardants
While polyester is inherently flame retardant, it is important to remember that some fabrics may require additional protection from flame or heat.
Fire retardants are chemicals applied to fabrics to reduce flammability and slow flame spread.
It is important to ensure that fabric is treated with fire retardants to provide maximum fire protection.
Can Polyester Be Treated With Fire Retardants?
Even though polyester is flame retardant, you can still treat it with fire retardants before and after fabrication. This increases the fabric's fire resistance and boosts its flame retardancy.
The procedure of applying fire retardants in polyester during fabrication consists of adding the chemical to the spinning solution of the fabric, thus incorporating the flame retardant into the material during its manufacturing process.
When applied after fabrication, the flame retardant is injected into the fabric using aerosol or spray methods.
