Synthetic fiber is a type of material made from chemical processes, rather than natural sources like plants or animals. Common examples include polyester, nylon, and acrylic. These fibers are often used in clothing, upholstery, and various industrial applications due to their durability and resistance to wrinkles and shrinking. The production of synthetic fibers typically involves the polymerization of small molecules into long chains, creating a strong and flexible material. They can be engineered to have specific properties, such as moisture-wicking or UV resistance, making them versatile for different uses in fashion and technology.
