What is pilling definition?

Pilling is the formation of tiny balls of fibers on the surface of fabric caused by abrasion or friction during wear or laundering. It is more common in synthetic fabrics such as polyester, acrylic, and nylon, but can also occur in natural fabrics like wool and cotton. Pilling can affect the appearance and texture of the fabric, making it look worn and shabby. Factors such as the quality of the fabric, the type of fabric, the construction of the garment, and the way it is laundered can all impact the level of pilling that occurs. Preventing pilling includes choosing high-quality fabrics, washing garments inside-out, using gentle detergents, and avoiding high-heat drying.
