Question

Which of the following set of polymers are used as fibre?
(i) Teflon
(ii) Starch
(iii) Terylene
(iv) Orlon

• A. (i) and (ii)
• B. (ii) and (iii)
• C. (iii) and (iv)
• D. (i) and (iv)

Answer 1

The Correct Option is C

• Teflon (i) is a polymer used primarily for non-stick coatings and not as a fiber.
• Starch (ii) is a polysaccharide used primarily in food, not as a fiber.
• Terylene (iii) is a polyester polymer, also known as PET (Polyethylene Terephthalate), which is widely used in the manufacture of fibers for textiles and clothing.
• Orlon (iv) is a type of acrylic fiber, a synthetic polymer used for making fibers in fabrics.

Thus, Terylene and Orlon are used as fibers, making option (C) the correct answer.

Answer 2

• Teflon (PTFE) is a high-performance polymer used primarily for non-stick coatings and not for fibres.  
• Starch is a natural polysaccharide but is not used as a fibre in textiles.  
• Terylene (also known as polyester) is widely used as a synthetic fibre for textiles and clothing.  
• Orlon is a synthetic acrylic fibre, commonly used in garments and upholstery.  

Therefore, Terylene and Orlon are the polymers used as fibre in the textile industry.
