Wide Fabrics Choice For Today’s Tire Maker When the Firestone company was founded in 1900, women had little variety to choose from in fabrics for clothing and home use. Tire makers, too, had little choice in fabrics for the primary structural or reinforcing material for their tire. In fact, the only choice for pneumatic tires was square-woven cotton fabric. Today, women enjoy a great variety of versa tile fabrics for different purposes. So do tire makers have variety. In 1915 the first experiments were conducted in the use of cord fabric for tires, consisting of a number of long-staple cotton cords lying parallel to each other and held together by an occasional yarn of small diameter. The same type of cord fabric construction was used in 1933 when the company first used man-made rayon in tires. Later nylon, steel wire and polyester cord were introduced. BY LATE 1963, Firestone was on the threshold of another exciting development in tire cord—fi berglass. It was announced that fiberglass cord is particularly promising for use in a new type of tire in which the cords run directly across the tire body instead of at an angle of 34 to 38 degrees from the circumferential direction as in con ventional tires. Fiberglass tire cord is made from the same tiny glass fibers for which there are now so many applications in both home and industry. Tires originally were of solid rubber, fastened around a carriage, bicycle, automobile or other wheel in various ways. But a softer ride was in demand and the idea of riding on air encased in a rub ber tube was developed. Robert William Thompson, an Englishman, built the first pneumatic tire in 1845. He used leather, both to cover and protect the rubber air tube and to give the tire strength. His tire met with little success. In 1888, John Boyd Dunlop of Belfast, Ire land, built his first pneumatic tire, consisting of a rubber air tube enclosed in a linen jacket. Flaps of the jacket were cemented to a wooden bicycle rim and the outside surface was covered with rubber sheeting. SQUARE-WOVEN COTTON, considered as a reinforcement about 1900, was the first reinforce ment material used that actually adhered to the rubber. This fabric was much like canvas and was used for 15 years until specially-designed cotton cord fabric was introduced. As transportation grew and motor vehicles traveled greater distances at ever-increasing speeds, more and more was demanded of tires. They had to be strong enough to withstand se- EVOLUTION OF TIRE CORD is represented here, as girl ai left wearing typical cotton costume of the early 1900s holds sample of square-woven cotton tire fabric and displays early Firestone Non-Skid tire.

Improved tire cords, along with better rubber compounds, made remarkable progress possible. Rayon appeared for tire cord about 20 years after cotton cord fabric. It was quickly accepted and from 1939 to 1949 gained 75 per cent of the tire market. During World War II rayon achieved universal use because it had the heat resistance necessary to withstand the higher-running tem peratures of the new synthetic rubber tires. Soon nylon was challenging rayon because it also had this characteristic. First used in aircraft tires during World War II, nylon became popular for off-road and heavy- duty truck tires; then penetrated the passenger- tire market. Makers of rayon cord met the competition by increasing strength, durability and adhesion of their products. Nylon cord makers also improv ed their cord by doubling its resistance to heat fatigue and greatly increasing durability, ad hesion and strength. PNEUMATIC-TIRE SALES now are split about evenly between nylon and rayon, in the overall original-equipment and replacement mar kets for trucks, buses and passenger cars. Steel wire cord provides the answer in many applica tions. Challengers have appeared for these tire cord materials, just as they have in women’s fashions and home furnishings. Each challenger has its own advantages and potentialities. In 1959 Firestone announced successful testing of tires made with cord fabric of polyester fibers, such as Dacron and Terylene, and recently the company announced testing of fiberglass cord. As in every field, the old standbys remain and continue to be improved in the textile field, but exciting new materials offer much promise for the future on the highways, as well as at home. 190.J SOUABf COTTCm FABRIC fabric Edison Biographer Mentions Firestone “Edison—that veritable dyna mo of genius and invention— typifies more than any of his peers the American dream. His education was limited to three months in a Port Huron, Mich., school. But the fires burned brightly within the lad who was, successively, a railroad newsboy and a telegraph operator, but who always found time to ex periment in his spare time. “Deafened at an early age, he forged on in an ever-growing world of silence, to give man kind, among other things, the electric light and the phono graph. The farm boy from Ohio (Milan was the original family home) brought light and music into the lives of millions.” SO BEGINS a review on the jacket of the new biography of Inventor Thomas Edison, written by Rex Beasley and published Feb. 11 by Chilton Books. “In Rex Beasley’s exciting book,” continues the review, Blood Donors —From page 1 McCurry, Cramer McDaniel, Edith McGinnis, William Mc Ginnis, Erma McNabb, James McNabb, Roxie McNabb, Jerry Mitchell, John Mitchell, Isaac Moss, Paul Neal, Roxie Newton, William O’Neal, William Page, Dillard Palmer.
