What does pilling mean on fabric?

Pilling on fabric refers to the formation of small, fuzzy balls or clusters of fibers on the surface of the material. This occurs when loose fibers become tangled and matted due to friction or wear over time. Pilling is common in various textiles, especially those made from wool, polyester, or blends, and can affect the appearance and feel of the fabric. Regular care, such as gentle washing and using a fabric shaver, can help reduce pilling.
