A Short History Of Nylon !
Nylon represents a family of synthetic polymers, a thermoplastic
material, invented in 1935 by Wallace Carothers at Dupont. The first product was
a nylon-bristled toothbrush (1938), followed more famously by women's stockings
(1940). It is made of repeating units linked by peptide bonds (another name for
amide bonds) and is frequently referred to as polyamide (PA). Nylon was the
first commercially successful polymer and the first synthetic fiber to be made
entirely from inorganic ingredients: coal, water and air. These are formed into
monomers of intermediate molecular weight, which are then reacted to form long
polymer chains. It was intended to be a synthetic replacement for silk and
substituted for it in parachutes after the United States entered World War II in
1941, making stockings hard to find until the war's end. Nylon fibers are now
used in fabrics and ropes, and solid nylon is used for mechanical parts and as
an engineering material.
During World War II, nylon replaced Asian silk in parachutes. It was also used
to make tires, tents, ropes, ponchos, and other military supplies. It was even
used in the production of a high-grade paper for U.S. currency. At the outset of
the war, cotton accounted for more than 80% of all fibers used, and manufactured
and wool fibers accounted for the remaining 20%. By August, 1945, manufactured
fibers had taken a market share of 25% and cotton had dropped.
Some people surmise that cannabis sativa was made illegal because the fibers
from the hemp plant, used for fabrics and ropes, were in strong competition with
nylon. But nylon fiber is more than twice as strong as hemp and weighs 25% less.
While hemp was originally used in climbing rope, this is no longer the case,
even in countries where cannabis is legal.
Some of the terpolymers based upon nylon are used every day in packaging. Nylon
has been used for meat wrappings and sausage sheaths.
Etymology (Where did the name NYLON originate?)
There is no evidence that nylon was named after New York and London. In 1940
John W. Eckelberry of DuPont stated that the letters "nyl" were arbitrary and
the "on" was copied from the names of other fibers such as cotton and rayon. A
later publication by DuPont (Context, vol. 7, no. 2, 1978) explained that the
name was originally intended to be "No-Run" ("run" meaning "unravel"), but was
modified to avoid making such an unjustified claim and to make the word sound
better. The story goes that Carothers changed one letter at a time until
DuPont's management was satisfied. There is another story (repeated in
James Burke's TV series Connections) that another one of the names considered
was to be Duparooh for DUpont Pulls A Rabbit Out Of a Hat. Nylon was never
