Concetti Chiave
- Polyesters are synthetic fibers derived from petroleum products and are known for their strength and resistance to abrasion.
- They have low water absorption, making them quick-drying and easy to wash without being affected by heat.
- Polyesters are crease-resistant and can be permanently pleated, but they do not dye easily.
- Commonly used to add strength to wool or cotton, they maintain whiteness better than other synthetic fibers.
- Polyesters are widely used in clothing, bedding, and home furnishings due to their durability and warmth.
Characteristics of polyesters
Polyesters are products of complex series of chemical processes using petroleum products and other chemicals. Polyesters include Terylene, Dacron, Tergal, Diden, etc.
1. They are very strong.
2. They are resistant to abrasion.
3. They do not stretch very much.
4. They do not absorb much water. They therefore dry up easily.
5. They are easy to wash.
6. They are not harmed by heat.
7. They are crease resistant.
8. They can be permanently pleated.
9. They do not dye easily.
10. They are generally warm to wear.
11. White polyester tend to stay whiter in wear than other man-made fibres.
12. Polyesters are often used to add strength to wool or cotton. By this, polyester or cotton and polyester of woolly blends are produced.
Uses of polyester
Polyesters are used for varieties of dresses, bedsheets, pillow cases, home furnishings, etc.
The properties of polyesters are practically different from that of the wool which is an animal based fibre.
Properties of wool:
1. Wool is elastic and springy to touch. It does not crease.
2. It makes a very absorbent fabric.
3. It is stronger when dry than when wet.
4. Wool fabric has large number of air spaces between the fibres. It is therefore very warm to warm. It retains body heat.
5. It can also absorb moisture very well without appearing damp.
6. It felts or shrinks easily especially when treated with hot water. This means that it stops stretching and reduces in size.
7. It is really affected by bleach.
8. It is attacked by clothes moth and other insects.
9. It gives the smell of burning feathers when burnt.

- What are the key characteristics that make polyester a popular choice for clothing and home furnishings?
- In what ways is polyester utilized in textile production?
Polyester is favored for its strength, resistance to abrasion, and ease of care. It dries quickly due to low water absorption, is crease-resistant, and can be permanently pleated. Additionally, it is not harmed by heat and maintains its whiteness better than other synthetic fibers.
Polyester is widely used in making dresses, bedsheets, pillowcases, and home furnishings. It is also blended with wool or cotton to enhance the strength of these natural fibers, resulting in durable polyester-cotton or polyester-wool blends.
