Nylon Manufacturing Process
Description
Production
of
nylon
is
a
complex
art
requiring
super
cleanliness
and
rigid
control
of
temperatures
and
pressures
. In the
manufacture
of
yarn
at the
textile
fiber
plants
, the
nylon
salt
solution
is
first
piped
into
evaporators
where
much
of the
solvent
is
removed
to
form
a
more
concentrated
solution
. This
flows
into an
autoclave-like
a
giant
pressure
cooker-where
small
molecules
link
up
to
form
long
chain-like
molecules
.
When
this
is
completed
, the
nylon
is
a
molten
syrupy
material
.
It
flows
from a
slot
in the
bottom
of the
autoclave
onto the
surface
of a
broad
,
slowly
revolving
casting
wheel
. A
shower
of
water
hardens
the
polymer
into a
translucent
milk
white
ribbon
,
which
is
then
chipped
up
into
small
flakes
. The
nylon
chips
from
several
autoclaves
are
blended
and
poured
into
hoppers
.
Grids
melt
the
flakes
and a
carefully
designed
pump
forces
the
viscous
molten
nylon
through
the
fine
holes
of a
spinneret
to
form
the
yarn
filaments
,
which
solidify
as they
hit
the
air
. The
filaments
are
gathered
into a
yarn
and
wound
on
bobbins
(above)
. The
yarn
is
later
stretched
, or
drawn
to
increase
its
strength
. The
DuPont
Company
makes
the
yarn
but
does
not
manufacture
fabrics
,
hosiery
or
other
finished
products
from
nylon
.
It
sells
the
yarn
to
other
companies
which
transform
it
into the
competed
consumer
products
.
