How will you distinguish among wool, cotton, silk, and synthetic fibres?
There is basically three way to distinguish the textile fibre.
Wool- When it comes in contact with flame get shrink initially. Smell of burning hair. Flame didn't propogate. Leave black Crushable ash.
Cotton- propogate flame as cotton comes in contact with flame with yellow flame. Smell of burning paper. Leave grey white ash.
Silk- Burns slowly, but does not melt. It shrinks from the flame. Smell of charred meat (some say like burned hair).
Synthetic fibre- mostly synthetic fibre shrink when they come in contact with flame. Smell like burning coal tar. Dark black beeds leave after burnout.
