Why should we not wear clothes made of synthetic fibres (like nylon or polyester) while working in the kitchen?

Synthetic fibres such as nylon or polyester are different from the natural fibres. They melt on heating. If the clothes made of synthetic fibres catch fire, it can be very dangerous. The fabric will melt and can stick to the body of the person wearing it. Hence, we should not wear synthetic clothes while working in a kitchen or working in a laboratory.
