History of Artificial Fibres

                  The world has, through out history, been limited to the use of fibres available in the natural world. Cotton and linen wrinkled from wear and washings. Silk required delicate handling. Wool shrank, was irritating to the touch, and was eaten by moths. Then, a mere century ago, rayon - the first manufactured fibre was developed. The secrets of fibre chemistry for countless applications had begun to emerge.
                  
                   Artificial fibres now are put to work in modern apparel, home furnishings, medicine, aeronautics, energy, industry, and more. Fibre engineers can combine, modify and tailor fibres in ways far beyond the performance limits of fibre drawn from the silkworm cocoon, grown in the fields, or spun from the fleece of animals.

The Early Attemps

                  The earliest published record of an attempt to create an artificial fibre took place in 1664. English naturalist Robert Hooke suggested the possibility of producing a fibre that would be "if not fully as good, nay better" than silk. His goal remained unachieved for more than two centuries.
                  
                  The first patent for "artificial silk" was granted in England in 1855 to a Swiss chemist named Audemars. He dissolved the fibrous inner bark of a mulberry tree, chemically modifying it to produce cellulose. He formed threads by dipping needles into this solution and drawing them out - but it never occurred to him to emulate the silkworm by extruding the cellulosic liquid through a small hole.

                   In the early 1880's, Sir Joseph W. Swan, an English chemist and electrician, was spurred to action by Thomas Edison's new incandescent electric lamp. He experimented with forcing a liquid similar to Audemars solution through fine holes into a coagulating bath. His fibres worked like carbon filament, and they found early use in Edison's invention.

                   It also occurred to Swan that his filament could be used to make textiles. In 1885 he exhibited in London some fabrics crocheted by his wife from his new fibre. But electrical lamps remained his main interest, and he soon abandoned work on textile applications.

First Commercial Project

                  French chemist Count Hilaire de Chardonnet achieved the first commercial scale production of a manufactured fibre. In 1889, his fabrics of "artificial silk" caused a sensation at the Paris Exhibition. Two years later he built the first commercial rayon plant at Besancon, France, and secured his fame as the "father of the rayon industry."
Several attempts to produce "artificial silk" in the United States were made during the early 1900's but none were commercially successful until the American Viscose Company, formed by Samuel Courtaulds and Co., Ltd., began its production of rayon in 1910.
                  
                   In 1893, Arthur D. Little of Boston, invented yet another cellulosic product - acetate - and developed it as a film. By 1910, Camille and Henry Dreyfus were making acetate motion picture film and toilet articles in Basel, Switzerland. During World War I, they built a plant in England to produce cellulose acetate dope for airplane wings and other commercial products. Upon entering the War, the United States government invited the Dreyfus brothers to build a plant in Maryland to make the product for American warplanes. The Celanese Company developed the first commercial textile uses for acetate in fibre form in 1924.

                   In the meantime, U.S. rayon production was growing to meet increasing demand. By the mid-1920's, textile manufacturers could purchase the fibre for half the price of raw silk. So began manufactured fibres' gradual conquest of the American fibre market. This modest start in the 1920's grew to nearly 70% of the national market for fibre by the last decade of the century.

Nylon - The Artificial Fibre

                  In September 1931, American chemist Wallace Carothers reported on research carried out in the laboratories of the DuPont Company on "giant" molecules called polymers. He focused his work on a fibre referred to simply as "66", a number derived from its molecular structure. Nylon, the "miracle fibre," was born.
                  
                   By 1938, Paul Schlack of the I.G. Farben Company in Germany, polymerized caprolactam and created a different form of the polymer, identified simply as nylon "6".
                  
                   Nylon's advent created a revolution in the fibre industry. Rayon and acetate had been derived from plant cellulose but nylon was synthesized completely from petrochemicals. It established the basis for the ensuing discovery of an entire new world of manufactured fibres.

An American Romance

                   DuPont began commercial production of nylon in 1939. The first experimental testing used nylon as sewing thread, in parachute fabric, and in women's hosiery. Nylon stockings were shown in February 1939 at the San Francisco Exposition - and the most exciting fashion innovation of the age was underway.

                   American women had only a sampling of the beauty and durability of their first pairs of nylon hose when their romance with the new fabric was cut short. The United States entered World War II in December 1941 and the War Production Board allocated all production of nylon for military use. Nylon hose, which sold for $ 1.25 a pair before the War, moved in the black market at $10. Wartime pin-ups and movie stars, like Betty Grable, auctioned nylon hoses for as much as $40,000 a pair in war-effort drives.
                  
                   During the War, nylon replaced Asian silk in parachutes. It also found use in tires, tents, ropes, ponchos, and other military supplies, and even was used in the production of a high-grade paper for U.S. currency. At the outset of the War, cotton was king of fibres, accounting for more than 80% of all fibres used. Manufactured and wool fibres shared the remaining 20%. By the end of the War in August 1945, cotton stood at 75% of the fibre market. Manufactured fibres had risen to 15%.

The Post-War Industry

                  After the war, GI's came home, families were reunited, industrial America gathered its peacetime forces, and economic growth surged. The conversion of nylon production to civilian uses started and when the first small quantities of postwar nylon stockings were advertised, thousands of frenzied women lined up at New York department stores to buy.

                   In the immediate post-war period, most nylon production was used to satisfy this enormous pent up demand for hosiery. But the end of the 1940's was also using it used in carpeting and automobile upholstery. At the same time, three new generic manufactured fibres started production. Dow Badische Company (today, BASF Corporation) introduced metalized fibres; Union Carbide Corporation developed modacrylic fibre; and Hercules, Inc. added olefin fibre. Manufactured fibres continued their steady march.

                   By the 1950's, the industry was supplying more than 20% of the fibre needs of textile mills. A new fibre, "acrylic," was added to the list of generic names, as DuPont began production of this wool-like product.

                   Meanwhile, polyester, first examined as part of the Wallace Carothers early research, was attracting new interest at the Calico Printers Association in Great Britain. There, J. T. Dickson and J. R. Whinfield produced a polyester fibre by condensation polymerization of ethylene glycol with terephthalic acid. DuPont subsequently acquired the patent rights for the United States and Imperial Chemical Industries for the rest of the world. A host of other producers soon joined in.

A Wash and Wear Revolution

                  In the summer of 1952, "wash and wear" was coined to describe a new blend of cotton and acrylic. The term eventually was applied to a wide variety of manufactured fibre blends. Commercial production of polyester fibre transformed the "wash and wear" novelty into a revolution in textile product performance.

                   Polyester's commercialization in 1953 was accompanied by the introduction of triacetate. The majority of the 20th century's basic manufactured fibres now had been discovered, and the industry's engineers turned to refining their chemical and physical properties to extend their use across the American economy.
                  
                   In the 1960's and 1970's consumers bought more and more clothing made with polyester. Electric dryers replaced clotheslines, and the "wash and wear" garments they dried emerged wrinkle free. Ironing began to shrink away on the daily list of household chores. Fabrics became more durable and color more permanent. New dyeing effects were being achieved and shape-retaining knits offered new comfort and style.

Endless Possibilities

                   In the 1960's, manufactured fibre production accelerated as it was spurred on by continuous fibre innovation. The revolutionary new fibres were modified to offer greater comfort, provide flame resistance, reduce clinging, release soil, achieve greater whiteness, special dullness or luster, easier dyeability, and better blending qualities. New fibre shapes and thicknesses were introduced to meet special needs. Spandex, a stretchable fibre; aramid, a high-temperature-resistant polyamide; and para-aramid, with outstanding strength-to-weight properties, were introduced into the marketplace.

                   In the early 1960's, artificial fibre accounted for nearly 30% of American textile mill consumption. By 1965, the manufactured fibre industry was providing over 40% of the nation's fibre needs.

                   One dramatic new set of uses for artificial fibres came with the establishment of the U.S. space program. The industry provided special fibre for uses ranging from clothing for the astronauts to spaceship nose cones. When Neil Armstrong took "One small step for man, one giant leap for mankind," on the moon on July 20, 1969, his lunar space suit included multi-layers of nylon and aramid fabrics. The flag he planted was made of nylon.

                   Today, the exhaust nozzles of the two large booster rockets that lift the space shuttle into orbit contain 30,000 pounds of carbonized rayon. Carbon fibre composites are used in as structural components in the latest commercial aircraft, adding strength and lowering weight and fuel costs.
