What is Fire Retardancy? According to Wikipedia, Fire Retardant fabrics are textiles that are naturally more resistant to fire than others through chemical treatment or manufactured fireproof fibers.
So how is the flame retardancy of silk fabrics reflected? Silk fabrics also are textiles, so it is easy to ignite on the fire, but it burns very slowly and burns out automatically after a while.
It is also a way to distinguish if it is real silk. Take a silk tread form 100% silk products, if the fire is slow and will be extinguished automatically, then must be 100% silk fabric.
Due to this characteristic of the silk, it can be used for home textiles, bedding, cushions, and windows.
