FR clothing, short for Flame-Resistant clothing, is an essential protective gear designed to minimize the risks associated with exposure to fire hazards and thermal incidents. But what is fr clothing made of? The materials used in FR clothing play a critical role in providing the necessary protection to individuals working in environments where flames, sparks, or electrical arcs are present.
So, let’s take a closer look at the materials that make FR clothing a vital component of personal protective equipment (PPE) in hazardous work environments.
Cotton-based FR Clothing
Cotton has long been a popular choice for clothing due to its comfort, breathability, and softness. When it comes to FR clothing, cotton is often used as a base material due to its inherent flame-resistant properties. However, untreated cotton is not sufficient to provide adequate protection against intense heat and flames.
To enhance the fire resistance of cotton, it undergoes a treatment process known as “FR treatment” or “FR finishing.” This treatment involves applying special chemicals to the fabric to create a protective layer that helps prevent the fabric from igniting, limits the spread of flames, and reduces the severity of burns. The FR-treated cotton fabric is commonly referred to as “treated cotton” or “treated FR cotton.”
Treated cotton FR clothing offers several advantages. It is comfortable to wear, lightweight, and allows for good breathability, making it suitable for a wide range of industries such as manufacturing, oil and gas, and utilities. Additionally, treated cotton FR clothing retains its flame-resistant properties even after repeated laundering, ensuring long-lasting protection for the wearer.
