Textile fiber is a basic unit of material used to create fabrics and textiles. These fibers can be natural, such as cotton, wool, and silk, or synthetic, like polyester and nylon. The properties of these fibers, including strength, elasticity, and moisture absorption, determine the characteristics of the final fabric. Fibers are spun into yarns, which are then woven or knitted to produce various textiles. The choice of fiber affects the texture, durability, and appearance of the fabric, making it essential in industries like fashion, upholstery, and home textiles. Understanding textile fibers is crucial for selecting the right materials for specific applications.
