Synthetic fibers are man-made materials used in textiles, including clothing, carpeting, and upholstery. These fibers are created through chemical processes, using petroleum-based or plant-based materials, such as polyester, nylon, rayon, and acrylic. Other synonyms to describe synthetic fibers include man-made fibers, artificial fibers, chemical fibers, and lab-created fibers. These fibers are known for their durability, strength, and resistance to moisture, making them popular for outdoor clothing and sportswear. While synthetic fibers have several advantages, they are often criticized for their negative impact on the environment and for their potential harm to human health.
