Flame Resistant Fabrics

What are Flame Resistant Fabrics?

INHERENT and ENGINEERED are the two terms used most to distinguish between FR fabrics. The difference between engineered and inherently flame resistant fabrics relates to the process used in making the final product flame resistant and can be described as

INHERENTLY Flame Resistant Fabrics, like Nomex® Essentials and Westex® DH Antistat, are made using fibers that are innately flame resistant. The flame resistant properties cannot be degraded through regular use or laundering. Nomex® Essentials and Westex® DH Antistat fabrics are made from fibers that are not flammable, from an FR polymer base; these fabrics are flame resistant from the start and do not go through a treatment process to become flame resistant.

ENGINEERED FR Fabrics, like Avenger and UltraSoft® undergo a process during manufacturing to impart flame resistance onto the fabric fibers. Treated cotton and blended fabrics are given a flame resistant chemical application, which the originally non-FR fabric is immersed in after it is woven together. The treatment chemically changes the fabric, making it flame resistant for the life of the garment

Both types of fabrics offer comparable protection. What matters most to wearers is that the FR is guaranteed for the life of the garment, provided that laundering instructions are followed and that no bleach, fabric softener or starch is used during the laundering process since such contaminants can mask the FR properties of the fabric.
