Staple fiber refers to textile fibers of discrete length, distinct from continuous filament fibers. These fibers can be sourced from natural materials like cotton and wool, or synthetic ones such as polyester. Their staple length, an average length of the fiber group, is crucial in yarn spinning. Longer staple fibers often result in smoother, higher - quality yarns, while shorter ones can be more challenging to spin and may produce hairier yarns. They are widely used in the textile industry for making various fabrics and products.
