Which fiber is a synthetic polymer widely used for clothing due to strength and elasticity?

• A. Wool
• B. Cotton
• C. Silk
• D. Polyester

Answer: (D)

Synthetic polymers designed for fabrics offer strength and elasticity, making them common in clothing. Polyester is a classic example: it’s a synthetic polymer whose fibers have high tensile strength and good stretch, so garments resist wrinkling and hold their shape after wear. It also dries quickly and accepts dye well, which keeps colors bright and fabrics easy to care for. Because of these versatile properties, polyester is used widely—often on its own or blended with natural fibers to boost durability and elasticity. The other options are natural fibers derived from animals or plants, with different textures and care needs, but they don’t combine strength and stretch in the same consistent way as polyester.
