Explanation:
In general, if the ash is soft and the odor is of burning hair or paper, the fabric is a natural fiber. Cellulosic fibers (cotton, linen and rayon) burn rapidly with a yellow flame. When the flame is removed, there is an afterglow, then soft gray ash.

Answer:
Fibers can also be identified through the smell of the smoke it gives off in burning, and the ash or melted bead that remains after it has burned. Some of the fabrics are blends, and the blend of fibers may make the burn test a rather unreliable test for fiber content.
