Clothes purely made of synthetic fibres are not comfortable in hot and humid weather as they are water resistant and do not absorb sweat from the body. They catch fire easily and stick to the body and cause severe burns and injuries.Therefore, they are not suitable in kitchen and laboratories. On the other hand, clothes spun out of fibres made by a mixture of synthetic and natural fibres do not cause such problems. Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing.
