Modacrylic Blend Fleece 

FR/AR Modacrylic blend fleece fabric delivers a high-performance combination of permanent, multi-hazard protection and everyday wearer comfort. By combining synthetic Modacrylic (55%) with complimentary Cotton (45%) in a brushed fleece knit, the fabric excels in harsh industrial environments. One of Modacrylic's most unique traits is its excellent blend compatibility. DRFIRE's 10oz FR/AR Modacrylic Blend Fleece is a heavy, high-performance protective fabric that combines permanent flame resistance with advanced moisture management. When exposed to flame or an arc flash, the built-in modacrylic fibres release a self-extinguishing gas to choke out the flames, creating a thick char that blocks extreme thermal energy.  

Waffle Liner

The Waffle Liner is an FR/AR insulating interior fabric lining used in heavy-duty industrial clothing. Unlike regular garment linings, it is woven into a three-dimensional grid or "waffle" pattern out of high-performance safety blends such as Modacrylic, Cotton or Nomex®. It is engineered to protect workers in electrical, utility and oil/gas sectors against extreme thermal arc flash and flash fire hazards. The recessed square pockets in the waffle trap pockets of air. This creates a lightweight, highly efficient thermal barrier that retains body heat in the cold and shields against sudden external radiant heat.
