What is Nylon
 Nylon is a generic designation for a family
of synthetic polymers composed of
polyamides (repeating units linked by amide
links).
 Nylon is a silk-like thermoplastic, generally
made from petroleum, that can be meltprocessed into fibers, films, or shapes.
 Semi-crystalline and generally very tough
materials with good thermal and chemical
resistance and extremely elastic.
History Of Nylon
 Nylon was the first commercially
successful synthetic thermoplastic
polymer. ... DuPont began its research
project in 1927.
 The first example of nylon, (nylon 66), was
synthesized using diamines on February 28,
1935 by Wallace Hume Carothers at DuPont's
research facility at the DuPont Experimental
Station.
 Now its one of the fully synthetic fabrics, and
used for a high variety of things.
What Is Nylon Used For
 Clothing – Shirts, Foundation garments,
lingerie, raincoats, underwear, swimwear and
cycle wear.
 Industrial uses – Conveyer and seat belts,
parachutes, airbags, nets and ropes, tarpaulins,
thread, and tents.
 It is used to make a fishnet.
 It is used as plastic in manufacturing machine
parts.
How Is Nylon Produced
 Nylon is made when the appropriate monomers (the
chemical building blocks which make up polymers) are
combined to form a long chain via a
condensation polymerisation reaction. The
monomers for nylon 6-6 are adipic acid and
hexamethylene diamine. ... The polymer has to be
warmed and drawn out to form strong fibres.
 Nylon is made via a condensation polymerization
reaction and is formed by reacting di-functional
monomers containing equal parts of amine and
carboxylic acid. The amides form at both ends of the
monomer in a process analogous to polypeptide
biopolymers.

How Is Nylon Recycled
This waste is disposed of by land filling while small
portion is incinerated.
Depolymerisation of polymer into their
constituent monomer like Caprolactum,
hexamethylene diamine and adipic acid6 or other
useful oligomers.
For some reason locked deep in polymer chemistry,
nylon is more difficult to recycle than polyester. ...
Some of the recycled nylon we use comes
from post-industrial waste fiber, yarn
collected from a spinning factory, and waste
from the weaving mills that can be
processed into reusable nylon fiber.
