Which fiber type is characterized as synthetic and known for its versatility in textiles?

Polyester is a synthetic fiber that is well-known for its versatility in textiles. Its production process allows for a variety of textures, strengths, and finishes, making it adaptable for numerous applications, including upholstery, clothing, and home furnishings. Polyester is resistant to stretching, wrinkling, and fading, which enhances its functionality in everyday use.

This fiber can be blended with other materials to improve characteristics such as durability and comfort, further demonstrating its versatility. Its ability to wick moisture away from the skin also makes it popular in activewear and performance fabrics. The other options, while valuable fibers, are either natural (like wool, cotton, and silk) or lack the extensive adaptability found in polyester, thus highlighting polyester's unique standing as a synthetic and versatile textile material.
