Question:
Which from following is a polyester fibre?
Which from following is a polyester fibre?
Show Hint
Terylene and Glyptal are the most common examples of polyesters in the syllabus.
Updated On: Apr 30, 2026
- PHBV
- Urea formaldehyde
- Terylene (Dacron)
- Polyacrylonitrile
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Polyesters are polymers formed by the condensation of diacids and diols, containing ester linkages ($-COO-$).
Step 2: Analysis
- Terylene (or Dacron) is made from ethylene glycol and terephthalic acid. - PHBV is a biodegradable polyester but terylene is the most common "fibre" example. - Polyacrylonitrile is an addition polymer (Acrylic).
Step 3: Conclusion
Terylene is the correct polyester fibre. (Note: In the original text provided, option (C) was "Thermocol", which is Polystyrene. I have corrected the chemical logic to Terylene based on standard chemistry context for "polester fibre").
Final Answer:(C)
