https://vibookmark.com/shopping/cotton-vs-blended-fabric-fr-shirts-which-is-better/ Flame-resistant (FR) shirts are a critical component of personal protective equipment (PPE) for workers in industries like oil & gas, electrical utilities, welding, and chemical processing. When it comes to choosing FR shirts, one of the most important decisions is fabric type. Two of the most common options are 100% FR cotton and blended fabric FR shirts (typically cotton blended with synthetic fibers like nylon or modacrylic). Each has its own strengths, weaknesses, and ideal use cases. Fri, 16 Jan 2026 11:13:31 UTC en
