The correct answer is option 3. Dacron.
Terylene is a polyester fiber that is also known by the trade name "Dacron." Let's delve into more detail:
Terylene/Dacron:
1. Chemical Composition:
Terylene is a type of polyester, and its chemical name is polyethylene terephthalate (PET).
The repeating units in its polymer chain consist of terephthalic acid and ethylene glycol.
2. Synthesis:
The production of Terylene involves a condensation polymerization reaction between terephthalic acid (or its dimethyl ester) and ethylene glycol.
This reaction results in the formation of long chains of polyester molecules with repeating units of the terephthalate ester.
3. Properties:
Terylene is known for its strength, durability, and resistance to wrinkles and abrasion.
It has good resistance to chemicals and is often used in fabrics for outdoor applications.
Terylene fabrics are easy to care for and have excellent wash-and-wear characteristics.
4. Applications:
Terylene is widely used in the textile industry for the production of fabrics and clothing. It is commonly blended with other fibers to improve certain properties.
Additionally, Terylene is used in the production of various products, including ropes, seat belts, conveyor belts, and insulation for electrical purposes.
5. Trade Name:
Terylene is a generic name for the polyester, but it is also known by various trade names depending on the manufacturer. One such common trade name is "Dacron."
Comparison with Other Trade Names
Orlon: Orlon is the trade name for acrylic fibers, not polyester. Acrylic fibers are synthetic fibers made from polymers of acrylonitrile.
Acrilan: Acrilan is another trade name for acrylic fibers, similar to Orlon.
Teflon: Teflon is a brand name for polytetrafluoroethylene (PTFE), which is a synthetic fluoropolymer of tetrafluoroethylene. It is known for its non-stick properties and is commonly used in cookware.
In summary, Terylene, also known as Dacron, is a polyester fiber widely used in the textile industry for its favorable properties, including strength, durability, and resistance to wrinkles. It is important to note that different trade names are associated with specific types of synthetic fibers, and in this case, Terylene is the trade name for polyester. |
