Which of the following is not a blended fibre ?
a). Tereylene
b). Terry-wool
c). Terry cot

Answer 2

Answer:

The answer is a) Terylene

Explanation:

• Fibers can be defined as polymers that exhibit strong intermolecular interactions between their chains. They appear crystalline due to the tightly-packed tremendous pressures. They are less elastomeric but have high tensile strength.
• Blended fibers can be made by mixing fibers, and the qualities of each fiber are thus incorporated into the mixture. They are also known as fiber mixes and combinations. Polycot is a blend of polyester and cotton, and Polywool is a blend of polyester and wool. Polycot is the most prevalent blended textile as it blends the features of natural and synthetic fibers.
• Terylene is a synthetic polyester fiber made up of the polymerization of ethylene glycol and terephthalic acid.  
• Terry wool is a blended fiber of terylene (polyester) and wool.
• Terry cot is a blended fiber of terylene and cotton.
• Hence, the answer is terylene because terylene is polyester, and the other terry wool and terry cot are blended fibers.
