　　Combustion characteristics: Both cotton fiber and linen fiber catch fire immediately when approaching the flame. They burn rapidly. The flame is yellow and emits blue smoke.

　　Difference in smell and ashes: The difference between the two in terms of the smell emitted during combustion and the ashes after burning is that cotton burns with a paper smell, and linen burns with a plant ash smell. After burning, cotton has very little powder ash, which is black or gray, while linen produces a small amount of grayish-white powder ash.
