The MaxiSoft engineering process imparts durable flame-resistant properties to cotton by producing an invisible, long chain flame-retardant polymer, impregnated into the core of every fiber. When flame comes into contact with MaxiSoft FR cotton, an insulating char is formed with no melting, dripping, smoldering or afterglow.
