On October 27, 1938, DuPont announces its new synthetic polyamide fiber will be called "nylon". From the article:
Nylon is a generic designation for a family of synthetic polymers, based on aliphatic or semi-aromatic polyamides. Nylon is a thermoplastic silky material[1] that can be melt-processed into fibers, films or shapes.[2]:2
Nylon was the first commercially successful synthetic thermoplastic polymer.[3] DuPont began its research project in 1930. The first example of nylon (nylon 6,6) was produced using diamines on February 28, 1935, by Wallace Hume Carothers at DuPont's research facility at the DuPont Experimental Station.[4][5] In response to Carothers' work, Paul Schlack at IG Farben developed nylon 6, a different molecule based on caprolactam, on January 29, 1938.[6]:10[7]
Nylon was first used commercially in a nylon-bristled toothbrush in 1938,[8][9] followed more famously in women's stockings or "nylons" which were shown at the 1939 New York World's Fair and first sold commercially in 1940.[10] During World War II, almost all nylon production was diverted to the military for use in parachutes and parachute cord. Wartime uses of nylon and other plastics greatly increased the market for the new materials.[11]
Nylon is made of repeating units linked by amide links[12] similar to the peptide bonds in proteins. Commercially, nylon polymer is made by reacting monomers which are either lactams, acid/amines or stoichiometric mixtures of diamines (-NH2) and diacids (-COOH). Mixtures of these can be polymerized together to make copolymers. Nylon polymers can be mixed with a wide variety of additives to achieve many different property variations. Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging).[13]
DuPont, founded by Éleuthère Irénée du Pont, first produced gunpowder and later cellulose-based paints. Following WWI, DuPont produced synthetic ammonia and other chemicals. DuPont began experimenting with the development of cellulose based fibres, eventually producing the synthetic fibre rayon. DuPont's experience with rayon was an important precursor to its development and marketing of nylon.[14]:8,64,236
DuPont's invention of nylon spanned a nine-year period, ranging from the start of the project in 1930 to its exhibition at the World Fair in New York in 1939.[14] The project grew from a new structure at DuPont, suggested by Charles Stine in 1927, in which the chemical department would be composed of several small research teams that would focus on “pioneering research” in chemistry and would “lead to practical applications”.[14]:92 Harvard instructor Wallace Hume Carothers was hired to direct the polymer research group. Initially he was allowed to focus on pure research, building on and testing the theories of German chemist Hermann Staudinger.[15] He was very successful as research he undertook greatly improved the knowledge of polymers and contributed to science.[16]
In the spring of 1930, Carothers and his team had already synthesized two new polymers. One was neoprene, a synthetic rubber greatly used during the war. The other was a white elastic but strong paste that would later become nylon. After these discoveries Carother’s team was made to shift its research from a more pure research approach investigating general polymerization to a more practically-focused goal of finding “one chemical combination that would lend itself to industrial applications”.[14]:94
It wasn’t until the beginning of 1935 that a polymer called "polymer 6-6" was finally produced. The first example of nylon (nylon 6,6) was produced by Wallace Carothers on February 28, 1935, at DuPont's research facility at the DuPont Experimental Station.[4] It had all the desired properties of elasticity and strength. However, it also required a complex manufacturing process that would become the basis of industrial production in the future. DuPont obtained a patent for the polymer in September 1938,[17] and quickly achieved a monopoly of the fibre.[16]
The production of nylon required interdepartmental collaboration between three departments at DuPont: the Department of Chemical Research, the Ammonia Department, and the Department of Rayon. Some of the key ingredients of nylon had to be produced using high pressure chemistry, the main area of expertise of the Ammonia Department. Nylon was considered a “godsend to the Ammonia Department”,[14] which had been in financial difficulties. The reactants of nylon soon constituted half of the Ammonia department’s sales and helped them come out of the period of the Great Depression by creating jobs and revenue at DuPont.[14]
DuPont's nylon project demonstrated the importance of chemical engineering in industry, helped create jobs, and furthered the advancement of chemical engineering techniques. In fact, it developed a chemical plant that provided 1800 jobs and used the latest technologies of the time, which are still used as a model for chemical plants today.[14] “The success of the nylon project thus had to do with its ability to achieve the rapid mobilization of a large number of DuPont’s chemists and engineers”.[14]:100–101 The first nylon plant was located at Seaford, Delaware, beginning commercial production on December 15, 1939. On October 26, 1995, the Seaford plant was designated a National Historic Chemical Landmark by the American Chemical Society.[18]"
