Which synthetic fibers are widely used in sportswear?

The choice of polyester and nylon as the correct answer is rooted in their unique properties that make them particularly suitable for sportswear. Both of these synthetic fibers exhibit excellent durability and resilience, which are essential for athletic garments that undergo significant stress and wear during physical activities.

Polyester is known for its moisture-wicking capabilities, allowing it to draw sweat away from the body and facilitate quick drying. This property ensures that athletes remain comfortable and dry, which can enhance performance during workouts or competitions. Additionally, polyester fabrics are resistant to shrinking, stretching, and UV rays, making them ideal for a variety of weather conditions.

Nylon, on the other hand, is valued for its strength and elasticity. It is lightweight yet incredibly strong, which allows for ease of movement and comfort. Nylon's smooth texture also adds to the comfort of garments, reducing friction against the skin, which is particularly beneficial during intense physical activity.

In contrast, the other materials mentioned such as cotton and wool, while natural and breathable, do not offer the same technical advantages for sports applications. Cotton absorbs moisture rather than wicking it away, which can lead to discomfort when wet. Silk and linen have different characteristics that do not align with the performance needs of sportswear, such as lower durability and
