Different Types of Flame Retardancy

Hospital Cubicle Curtains are required to be flame retardant (aka fire retardant or shortened as FR). There are different types of flame retardancy.

Temparory flame retardancy (TFR) is maintained by post-woven chemical treatment, either through a flame retardant back-coating or dipping the fabric into a chemical solution, which absorbs into the fibres, creating a barrier between the fibre and the flame. Should the fabric catch fire, the chemicals applied during the fabric treatment process are activated by the heat, triggering a chemical reaction which extinguishes the flame. However, most flameproofing chemicals are water soluble and will also dissipate through dry cleaning. The flame retardancy of TFR (temparorily flame retardant) fabric tends to fade away with washing.

A second type is called Inherently Fire Retardant (aka Inherently Flame Retardant, or shortened as IFR) or Permanently Fire Retardant (aka Permanently Flame Retardant or shortened as PFR). IFR or PFR fabric is woven from flame retardant fiber and therefore the feature lasts for the lifetime of fabric and does not diminish by washing.

The cubicle curtain fabric LONGWAY supplies is permanently flame retardant (PFR), aka inherently flame retardant (IFR). It is tested according to  BS 5867-2:2008 Type C standard both before washing and after 50 cycles of standard washing (in accordance with BS EN ISO 10528: Automatic machines (Type A) at 75+/-3 degC in ECE detergent with sodium perborate, tumble dry).
