Check each fiber type against fire behavior. Cotton and jute (vegetable fibers) catch fire easily. Wool and silk (animal fibers) can char and burn, though wool resists flame better than cotton. Nylon and polyester (man made fibers) melt and burn when exposed to flame. Only fibers made from minerals, such as asbestos and fiberglass, are inorganic, so they cannot support combustion. $\boxed{\text{Mineral Based Fiber}}$
