Flame Resistant Clothing and Apparel

DRIFIRE® is engineered to be inherently flame resistant, providing an additional layer of protection when you need it most. Unlike garments with flame resistant treatments, DRIFIRE's performance will not deteriorate over time and has no-melt or drip characteristics, which means it will not melt into your skin in high heat.

DRIFIRE provides a safe, effective performance undergarment solution for people that have the potential to be exposed to flame or flash fire.

Modacrylic is the predominate fiber in DRIFIRE garments. First created in 1949, modacrylic has a proven, well-documented flame resistance (FR) pedigree and has been used is a wide variety of everyday products. Modacrylic does not combust. And not only are the fibers difficult to ignite, but they will self-extinguish. Technically speaking, modacrylic is a synthetic copolymer fiber. Practically speaking, for all the reasons noted here, our application of modacrylic in DRIFIRE garments results in FR protection plus a wide range of additional benefits based on this fiber’s outstanding overall properties.

First, our patented application of modacrylic fiber in DRIFIRE garments is the key to our flame resistance technology. In short, FR is built in to the product. Since 85% or more of the fabric is woven from modacrylic and modacrylic does not burn sustainably – nor will it drip, melt and fuse to the skin when exposed to flame or intense heat – this FR protection is permanent. In contrast to FR agents that are added in or layered on to combustible fabrics, driFIRE’s FR feature is forever. It does not wash away or wear out. There are no caustic agents or dangerous chemical compounds in modacrylic, nor are any added to our garments before, during or after the process of garment manufacture.

Modacrylic's Other Astonishing Properties

While modacrylic’s chief feature is its ability to provide flame resistance, it achieves this with a relatively low fabric density. This means that exceptionally low-weight, high-comfort garments like ours can be produced. But that’s not where the benefits of this fiber end. Soft, strong, resilient, and dimensionally stable, modacrylic fibers show good press and shape retention and are quick to dry. They have outstanding resistance to chemicals and solvents, are not attacked by moths or mildew, and are non-allergenic. Fabric experts will also often note that modacrylic features relatively high durability comparable to wool, a moderate resistance to abrasion, and a very low tenacity. As a result, modacrylic-based blends are soft, warm, light and resilient and display high performance when it comes to appearance retention. The fibers do not wrinkle, they have great dimensional stability, high elastic recovery, and the overall ability to hold their shape.
