Pilling happens when loose fibers rub, tangle, and remain attached to the fabric surface. It cannot always be prevented completely, but reducing friction, choosing an appropriate cycle, and limiting unnecessary heat can slow it significantly, especially on knits and synthetic blends.
Separate abrasive items from pill-prone fabrics
Jeans, fasteners, hook-and-loop strips, and heavy garments increase abrasion. Wash sweaters, fine knits, and delicate fabrics with similar textures, and close zippers or hooks that could catch fibers.
Turn pill-prone garments inside out
Washing inside out reduces some visible abrasion on the outer surface. It can also protect prints and brushed finishes, although it cannot eliminate wear occurring within the fabric structure.
Use no more agitation than the fabric needs
Follow the care label and use a gentle cycle when appropriate. Overloading does not protect clothes; it can increase rubbing and also prevent water and detergent from circulating properly.
Limit unnecessary dryer heat and time
High heat and prolonged tumbling can speed wear in some fibers. Remove clothing when dry and use low heat or air drying when the care label and fabric call for it.
