Inherent Vs Treated FR Fabrics

Inherent Vs Treated FR Fabrics

Jun 24, 2017

In a well-known marketing campaign, cotton was coined “The Fabric of Our Lives” largely because of its prevalence in many apparel choices. This extends to workwear and personal protective equipment (PPE), where cotton-based safety apparel is becoming the normally. While we often turn to cotton for our work clothing, it may not be the optimal material to protect lives when exposure to flame, extreme heat, molten metal, hot liquids, and arc flash are real possibilities.

Many workers who daily confront exposure to flame, extreme heat, molten metal, hot liquids, and arc flash routinely wear a simple cotton T-shirt and briefs as their “protective” base layer. They may also wear typical cotton “greens” or jumpsuits, shirts and coveralls that are chemical treated to be flame resistant. This common PPE combination is relatively inexpensive and permitted under current industry safety standards and regulations, but does it offer the level of protection required for the risk?

Most fabrics made of natural fibers, like cotton, and most synthetic fibers will burn or melt when exposed to a flame or electric arc. Flame-resistant (FR) fabrics ignite with difficulty, burn slowly when set on fire, and most importantly, self-extinguish when the heat source is removed. FR fabrics are produced in one of two ways: Either the fabric is made from inherently FR fibers or a non-FR fabric is chemical treated to provide FR properties.

Inherent FR fabrics are made of fibers in which the FR properties are naturally part of the polymer backbone and can never be worn away or washed out. The actual structure of the fiber itself is non-flammable; therefore, the flame trait is permanent.

Treated FR fabrics are created by applying a flame-retardant chemical finish to a fabric or by adding a chemical treatment to the fibers before they are woven or knitted into the fabric. The chemicals form a strong bond with the polymer chain that is difficult to remove by washing when the recommended laundering instructions are followed accurately. The chemical treatment alters the molecular structure of the polymer.

The chemical FR treated fabric is mainly used for oil & gas workwear,firefighting daily coverall, welding workwear, is ecnomic for mostly workers.

The inherent FR fabric used for pilot coverall,oil & gas workwear,firefighter workwear,etc, it is expensive,but the fireproof fabric performance is the best now.
