Curtains includes eyelet curtain, wave curtain, hospital curtain, PVC curtain, stage curtain, etc. Flame retardant (FR) fabrics are created by applying flame retardant chemicals. Flame retardant chemicals are dissolved in water and then applied to the fabric through dipping or spraying. When the fabric becomes dry from this process of application, flame retardant chemicals adhere to the fabric fibers which make the fabric Flame Retardant on an impermanent basis. Humidity and airborne dust and oils can also diminish the endurance and effectiveness of the flame retardant chemical.
A fabric is categorized as IFR if woven with threads that yield a product that meets fire code standards, without being subject to any special processing or addition of chemicals. IFR fabrics are expected to remain flame retardant for their lifetime, even after repeated washings. The “inherently flame retardant” phrase has been used in this manner for nearly a century now.
A small amount of preparation can save you from a ton of headaches in the long run!
