Wool is the most natural fire retardant fabric. All fabrics will burn but some are more combustible than others. Untreated natural fibers such as cotton, linen and silk burn more readily than wool, which is more difficult to ignite and burns with a low flame velocity.
In terms of flammability:
SILK & COTTON – has a very high burning rate
SYNTHETICS - tend to be slow to ignite but once ignited, severe melting and dripping occurs
WOOL - is comparatively flame-retardant. If ignited, it usually has a low burning rate and may self-extinguish. |
