FR fabrics are woven from threads that do not meet fire codes, but are topically treated with a flame retarding chemical so that the end product meets fire safety codes. Before the fabric is treated, it is defined as “NFR” or “non flame retardant.” Once the fabric has been correctly treated, it can be labeled “FR.”
The FR chemicals are dissolved in water and then introduced to the fabric by spraying or dipping. Once the fabric dries from this application process, the FR chemical remains adhered to the fibers of the fabric, making the fabric flame retardant, but possibly on a temporary basis. Any future wetting of the fabric will dissolve the chemical and likely remove all or portions of the chemical from the fabric. This renders all or portions of the fabric NFR. When this happens, the fabric should be thoroughly washed (with water) and then re-treated to restore the flame resistance.
