Knowra Nylon 6,6 Nylon 6,6 Nylon 6,6 is a synthetic polyamide made by reacting hexamethylenediamine with adipic acid. Its repeating units contain six carbon atoms from each monomer.
Polycondensation : A polymerization process in which monomers join while releasing small molecules such as water. Nylon 6,6 forms when its monomers link and release water.
Nylon stockings : Sheer hosiery made from fine synthetic fibers, especially nylon. Nylon 6,6 helped make durable, lightweight stockings a mass-market product.
Nylon 6 : A synthetic polyamide commonly made by ring-opening polymerization of caprolactam. Nylon 6 uses one monomer, unlike nylon 6,6's diamine-and-diacid route.
Wallace Carothers : An American chemist who led DuPont's polymer research and helped develop nylon and neoprene. Carothers's polymer research produced the chemistry underlying nylon 6,6.
Synthetic fiber : A manufactured fiber made from chemically produced polymers rather than natural materials. Nylon 6,6 helped establish synthetic fibers as competitors to silk, cotton, and wool.
Hexamethylenediamine : An organic diamine with six carbon atoms between two amino groups. This monomer supplies the diamine half of each nylon 6,6 repeat unit.
Nylon tire cord : High-strength nylon fibers embedded in rubber to reinforce tires. Nylon 6,6 tire cord resists fatigue and impact under repeated road loading.
Polyester : A polymer whose backbone contains recurring ester linkages. Polyester fibers compete with nylon 6,6 in apparel and industrial textiles.
DuPont : An American chemical company founded in 1802 that became a major industrial materials producer. DuPont developed nylon 6,6 and organized its commercial production.
Nylon riots : Public disturbances around the return of nylon stockings to American stores after World War II. Pent-up demand for nylon hosiery produced dramatic crowding and unrest in 1945.
