Fibers are thin strands of material that can be natural or synthetic. They are used in a variety of products, including clothing, ropes, and textiles. Natural fibers come from plants, animals, or minerals, while synthetic fibers are made through chemical processes. Common examples of natural fibers include cotton, wool, and silk, whereas synthetic fibers include polyester and nylon. Fibers play a crucial role in the textile industry, influencing the texture, durability, and appearance of fabrics. They can be spun together to create yarn, which is then woven or knitted into various materials. The choice of fiber affects the final product's properties, such as breathability and moisture-wicking capabilities.
