Which of the fabrics made from silk, wool, cotton, and jute traps air the most? How does such trapped air affect the property of such fabric?
Among the mentioned natural fibers, wool is the natural fiber which has the highest air trapping capacity.
Air is a bad conductor of heat and hence woolen clothes are preferred for winter months as the trapped air helps to keep the body warm as it prevents the heat from the body to escape out. This is the major reason why woolen clothes are preferred in winter months.
