Modacrylic staple fiber

Modacrylic fibers are produced from resins that are copolymers of acrylonitrile combined with materials such as vinyl chloride, vinylidene chloride, or vinyl bromide. These fibers can be manufactured using either dry spinning or wet spinning techniques. Inherently flame-resistant, modacrylic fibers possess intrinsic FR properties. They are often blended with other FR fibers like lyocell, aramid, or polyamide-imide to create durable fabrics that enhance comfort while maintaining excellent flame-resistant protection.

It exhibits exceptional charring properties when subjected to flame and high temperatures, without melting or dripping. The char formation acts as a barrier to prevent flame spread and extinguish burning once the flame source is removed. With no melting or dripping, it eliminates the risk of hazardous molten droplets that could adhere to the skin and cause severe burns, a concern commonly associated with polyester and other thermoplastic fibers.

When evaluating flame-resistant (FR) clothing, it’s essential to prioritize durability, comfort, and protection. Modacrylic fibers excel in all these areas, offering a synthetic fiber that is soft, robust, and resilient. This makes it highly suitable for protective clothing and technical FR fabrics. Below, you’ll discover why Modacrylic fibers should be a top consideration for your personal protective equipment (PPE) needs.
