What is Pilling in Fabric? कपड़े में गोलियां कैसे बनती है ? what is cotton fabric? what is polyester?

A pill, colloquially known as a bobble, fuzzball, or lint ball is a small ball of fibers that forms on a piece of cloth. 'Pill' is also a verb for the formation of such balls. Pilling is a surface defect of textiles caused by wear, and is generally considered an undesirable trait. It happens when washing and wearing of fabrics causes loose fibers to begin to push out from the surface of the cloth, and, over time, abrasion causes the fibers to develop into small spherical bundles, anchored to the surface of the fabric by protruding fibers that haven't broken. The textile industry divides pilling into four stages: fuzz formation, entanglement, growth, and wear-off. Pilling normally happens on the parts of clothing that receive the most abrasion in day-to-day wear, such as the collar, cuffs, and around the thighs and rear on trousers.
