The History of Nylon
6. Density 1.084 g/ml
Melting point 493 k
Caprolactum is a molecule used to synthesize nylon 6 by ring opening
polymerisation.nylon6 or polycaprolactum is a polymer developed by
PAUL SCHLACK. It is a semicrystalline polyamide unlike most other
nylon,nylon6 is not a condensation polymer but instead is formed by
ring opening polymerisation this makes it is a special case in the
comparision btw condensation and addition polymers. It has the
competition btw nylon 66 in the fibre industry. It is common in many
trade names.
7. preparation
1. Nylon 6 is prepared by ring opening polymerisation of
caprolactum.It is heated about 533k in an intert
atmospheric nitrogen about 4-5 hrs.The ring breaks and
undergo polymerisation,the molten mass pass through
spinnerts to form nylon 6

9. Applications
1. Used as thread in bristles for tooth brushes
2. As gears ,fittings & bearings, automotive
industry
3. Threads, ropes, filaments , nets
4. Gun frames
5. Surgical sutures, strings for musical
instruments
6. In hosiery and knitted garments
11. Many people hang banners for holidays and special occasions,
such as birthdays or anniversaries. Creating your own banners allows
you to customize them to your particular event and taste. When
making banners to hang outdoors, nylon fabric can be used to stand
up to the elements. Nylon fabrics come in a variety of colors,
maintain their shape and resist fading over time.

14. Whether you are supporting your favorite sports team, drawing
attention to a political issue or just displaying your own personal
independence, making your own flag out of nylon is a fairly easy
process and is an inexpensive way to showcase your personal style.
Decorative nylon flags are very easy to customize, and they are more
durable and weather-resistant than cotton...and less expensive than
polyester.

16. Nylon Ropes:
Nylon ropes and cords are high strength and have
excellent UV and abrasion resistance. They are resistant to
mildew, motor fuels, oils, cleaning fluids and many other
chemicals. Do not float.

18. Nylon in Medical:
This is a synthetic polyamide material, which can be used in the
form of:
• Monofilament
• Multifilament
• Braided
The main disadvantage is that a triple knot must be tied.
19. Nylon Brush:
Nylon filled industrial brushes are suitable for a range of applications
from aggressive scrubbing to dusting, in both dry and wet
environments. Brushes with Nylon fill offer the following
characteristics in most applications: excellent fatigue life, good
abrasion resistance, low to moderate absorption of water (3% to 9%)
leading to only a temporary reduction in stiffness, an excellent bend
recovery rate, resistance to most common solvents, and suitability
for use in weak acids.
