Why do socks pilling?
Because the socks you bought are fiber, not pure cotton.

Pilling of socks is caused by short fibers or broken fibers on the fabric surface. Water-repellent fibers are easy to adsorb each other and not easy to fall off the surface of the fabric, so water-repellent fibers are easier to pilling than hydrophilic fibers.

100% cotton fabric hardly produces pilling, but polyester fiber and cotton blended clothes are easy to pilling after wearing for a period of time.
