For centuries man has gratefully accepted the protective qualities of wool. By the carefully crossbreeding of sheep, he has developed fibers of different lengths, diameters, and various degrees of softness and crispness. Wool is almost custom-made by nature to fit the needs of man. In its processing and manufacture, man takes up where sheep left off. But while new processes and treatments have made wool more versatile in its uses, man has not improved the fiber itself. Wool has a number of characteristic that make it an ideal material.
Wool is the only fiber possessing a natural crimp, or wave. It is the crimp which gives wool its resiliency and vitality. Wool can be stretch to 50 percent of its length and return to its original dimension without damage. It can be twisted out of shape and subjected to repeated strain under dry or wet conditions. The crimps will always return to their original position.
The outer scaly covering of wool sheds water, making it naturally rain resistant. The protein cortex, on the contrary, readily absorbs moisture. Like a sponge, wool cab absorb up to 30 percent of its weight in water or body vapor without becoming damp. This quality also enables woolen clothing to absorb normal perspiration. Wool provides the most warmth with the least weight. This is due to the millions of air spaces enclosed within its compression-resistant structure. In clothing, wool acts as a shield against cold and hot air. It regulates the lost or gain of heat and keeps the body at its normal temperature.
Wool is the most naturally wrinkle-resistant of all fiber. It spindle-shape molecules have and affinity for one another and a determination to remain folded together in their normal arrangement. Wrinkles cause by body movements during wear or compression in a suitcase displace and stretch the material. When the wool relaxes, it corrects any displacement and returns to its original position, eliminating the wrinkles. Wool
