• A. Nylon
• B. Polyester
• C. Acrylic
• D. All of these

Answer 1

The correct option is D

All of these

Explanation of correct answer

(D) All of these

Synthetic fibers

• The term "synthetic fibers" refers to fibers produced by humans.
• Small molecule polymers are produced and then used to make synthetic fibers.
• By polymerizing these substances, a chemical that links two nearby carbon atoms is created.

All of these

• Petrochemicals are petroleum-based materials that are used to make various types of fibers such as nylon, polyester, and acrylic.
• Different types of fibers, including nylon, polyester, and acrylic, are all made using petrochemicals, which are byproducts of the petroleum industry.
• Based on chemicals or petrochemicals, synthetic fibers are produced from basic sources like petroleum.
• Unlike nylon, which is a man-made/synthetic fiber, rayon is a regenerated cellulose fiber.

(A) Nylon

• Nylon polymers offer a wide range of commercial uses in textiles and fibers.

(B) Polyester

• Polyester is a form of polymer in which each repeat unit of the main chain has an ester functional group.

(C) Acrylic

• Acrylic fiber is commonly utilized in sweaters, tracksuits, boot and glove linings, as well as furnishing fabrics and carpets.

Explanation of incorrect answer

• All the options (A), (B) and (D) are correct.

Therefore, the correct option is (D) All of these
