Concetti Chiave
- Nylon is a synthetic polyamide, produced through complex chemical processes involving coal or petroleum, water, and air.
- This thermoplastic material is strong, abrasion-resistant, elastic, and does not crease easily, making it suitable for various applications.
- Nylon is lightweight, easy to wash, quick-drying, and does not require ironing, enhancing its practicality for everyday use.
- Despite its many advantages, nylon can be uncomfortable in hot weather and is weakened by prolonged sunlight exposure.
- Common applications of nylon include garments like underwear, nightwear, stockings, as well as household items like curtains, carpets, and upholstery.
Nylon is the family name for all synthetic polyamides.

Production process
Nylon is made through a complex series of chemical processes, using coal or petroleum, water and air. It can be made into continuous filaments or short lengths (staple yarn). Nylon is a thermoplastic, silky material, it was first used commercially in a nylon-bristled toothbrushin 1938. Nylons are condensation copolymers, formed by reacting difunctional monomers containing equal parts of amine and carboxylic acid.
Characteristics of nylon
1. It is very strong. Strength is not affected by wetting.
2. It resists abrasion well.
3. It is very elastic and does not crease easily.
4. It does not absorb much water.
5. It has smooth surface. Therefore it is resistant to soiling.
6. It is easy to wash. It dries easily.
7. It is light in weight.
8. It requires no ironing.
9. It is durable.
10. It is resistant to mildew and moth.
Disadvantages of nylon
11. It is not comfortable to wear in hot weather.
12. It does not shrink.
13. White nylon may become grey or yellow with age.
14. It is weakened by prolonged exposure to sunlight.
15. It is often blended with wool or cotton.
Nylon tend to cling to the skin especially during harmattan or cold season. It is said to be electro-static.
