Inherent fire retardant (IFR) and back-coated (NDFR), are the two standards for fire retardant fabrics. With IFR being durable and NDFR being non-durable.
For inherent fire retardant (IFR) the fabric is woven using modern day fire retardant yarns, rated for durable, hard wearing, repetitive commercial uses; where washing is key criteria for not losing the fire retardant standards required.
Not all fabric qualities can achieve IFR standard due to the practical availability of IFR yarns, in this instance, we can back-coat and spray any fabric with chemicals to fire ratings. Fire retardant sprays are 100% durable for up to 10 washes maximum, however, they have the advantage of being applied to any fabric. Continue reading “Fire Retardant Fabric Explained”
