Since the products were not really run-proof, the vowels were swapped to produce "nuron", which was changed to "nilon" "to make it sound less like a nerve tonic". Most nylons are made from the reaction of a dicarboxylic acid with a diamine e. Frank All nylons are susceptible to hydrolysis , especially by strong acids , a reaction essentially the reverse of the synthetic reaction shown above. Category Commons. Incinerating nylons to recover the high energy used to create them is usually expensive, so most nylons reach the garbage dumps, decaying slowly. It Happened in Delaware.

Scientists explained this as a result of air pollution, attributing it to London smog in , as well as poor air quality in New York and Los Angeles. Due to the large number of diamines, diacids and aminoacids that can be synthesized, many nylon polymers have been made experimentally and characterized to varying degrees. In general linear polymers are the most useful, but it is possible to introduce branches in nylon by the condensation of dicarboxylic acids with polyamines having three or more amino groups.

Retrieved 23 May From scientific discoveries relating to the production of plastics and polymerization, to economic impact during the depression and the changing of women's fashion, nylon was a revolutionary product. Nylon was the first commercially successful synthetic thermoplastic polymer. However, it also required a complex manufacturing process that would become the basis of industrial production in the future. Se vuoi comprare delle vere calze di nylon , devi porre molta attenzione alla taglia, poiché, a causa delle caratteristiche del materiale, non sono elastiche.

New York Daily News. Cambridge: Woodhead. However, it also required a complex manufacturing process that would become the basis of industrial production in the future. Nylon can be used as the matrix material in composite materials , with reinforcing fibers like glass or carbon fiber; such a composite has a higher density than pure nylon. Conflicts in Chemistry: The Case of Plastics.

A smaller number have been scaled up and offered commercially, and these are detailed below. When being molded, nylon must be dried to prevent hydrolysis in the molding machine barrel since water at high temperatures can also degrade the polymer. DuPont began experimenting with the development of cellulose based fibers, eventually producing the synthetic fiber rayon.

If subjected to cold drawing afterwards, the fibers align further, increasing their crystallinity, and the material acquires additional tensile strength. The absorption of water will change some of the material's properties such as its electrical resistance. Its various properties also make it very useful as a material in additive manufacturing ; specifically as a filament in consumer and professional grade fused deposition modeling 3D printers. Eckelberry of DuPont stated that the letters "nyl" were arbitrary and the "on" was copied from the suffixes of other fibers such as cotton and Rayon.
