WHY WOOL Is WARMER Than LINEN THE main difference between wool and linen is that wool is animal and linen Is vegetable, and that the fiber of wool is Irregular, while that of linen is straight and regular. When the irregular fiber of the wool is woven it coutalns certain little cells which hold a neutral layer of air. The linen has no such cells. This layer of air which the cells make is like an invisible coat that keeps the normal heat of the body from leaving it and which at the same time keeps the atmosphere which is colder than the body temperature from entering it This layer of air is. as some writer has put it, a little gaseous armor. If woolen yarn is rendered straight and regular by some special treatment in the mill, and is woven like linen, it is only very little warmer than linen. That little is due to its being animal, which has always al-ways more warmth to it than vegetable product
