Which of the following best describes synthetic fibers?

Synthetic fibers are best described as fabrics manufactured from chemical processes using materials like wood pulp, petroleum, or natural gas. These fibers, such as nylon, polyester, and acrylic, are created through the manipulation of inorganic and organic compounds, which allows for a wide range of properties, including durability, elasticity, and resistance to moisture. Since they are not derived from natural sources, they stand in contrast to natural fibers, which come from plants and animals.

While the other choices refer to natural materials or specific applications, they do not accurately capture the essence of synthetic fibers, which are fundamentally about the use of man-made processes and non-natural raw materials. Thus, understanding the production process and sources of synthetic fibers is key to recognizing their identity within the textile industry.
