2.  Nylon is the first man made synthetic fiber (pure
chemical fiber).
 Manufactured from petroleum derivatives and
extruded from the spinneret and draw in desired
length.
 Two varieties of nylon is used in apparel purpose –
nylon 6 and nylon 6.6
 Nylon 6 polymer is made under the pressure,
extruded, chipped into flakes and melt spun through
spinneret, then filaments are cold drawn.

3.  Strength – good tenacity. Strongest textile fiber.
Strength lost when wet. But has excellent abrasion
resistance.
 Elasticity – good elasticity. High elongation and
excellent recovery.
 Resilience – excellent resilience. Retains smooth
appearance and wrinkles from daily activities.
 Drapability – excellent draping qualities. Light weight
sheer nylon has high draping quality. Medium weight
can drape very nicely.

4.  Heat conductivity – nylon of open construction will
be cooler than closed construction ex net.
 Absorbency - low. Water remains on surface and
hence dries quickly. So its suitable for raincoats.
 Cleanliness and washability – easy care garments.
Dirt doesn’t cling and can be wiped with damp cloth.
As its thermoplastic fiber usage of hot water should be
avoided.
 Reaction to bleaches – nylon are white and doesn’t
need bleach. Graying nylon should be bleached with
oxidizing bleach like hydrogen peroxide.

5.  Shrinkage – retains shape after washing and doesn’t
shrink.
 Effect of heat – should be ironed in low temp. hot
iron would result in glazing and then melting of fabric.
 Effect of light – low resistance to sunlight. So not at
all suitable for curtains or draperies.
 Resistance to mildew – doesn’t get attacked with
mildew.
 Resistance to insects – doesn’t get attacked with
moths or insects.

6.  Reaction to alkalis – prolonged exposure to alkali
weakens the fabric. Or else its excellent resistance.
 Reaction to acid – less resilient to the action of acids
but id damaged by strong acids.
 Affinity for dyes – nylon can be easily died and has
good resistance to fading.
 Resistance to perspiration – nylon are resistant to
perspiration.

7.  Lingerie, suiting, blouses/shirts,
 knitwear, hosiery, children's wear, beachwear,
 raincoats, gloves,
 tights, fur fabrics,
 blankets, curtaining and upholstery,
 carpets, ropes,
 nets and tyre cords.

19.  When washing nylon – separate white and color
fabrics and can use cold to hot water.
 Dry nylon flat or in dryer on cool temperature.
 Iron can be done on reverse side of fabric or else only
little steam can be done.
 Dry cleaning nylon can be done but no bleaches.

20.  The basic manufacturing process includes the
petroleum derivatives which are extruded from the
spinneret and drawn in desired length.
 Nylon is a thermoplastic polyamide fiber composed of
carbon, hydrogen, oxygen and nitrogen.
 Basic raw material is coal
 They have excellent strength, resilience, resistance to
insects etc.
 Fabric has low absorbency making them suitable for
the rain wear.
