Pilling is the small fibre balls that appear on a blanket after a few weeks of use. It is the most common complaint about throws, and it is almost entirely misunderstood.
Pilling is friction, not poor quality
Fabric is made of fibres twisted into yarn. Some of those fibres are short, and short fibres work loose at the ends. Friction — a body moving against the blanket, a washing machine drum, a dryer — rolls those loose ends into balls that stay attached by whatever fibre is still anchored.
Expensive blankets pill. Cheap blankets pill. What changes is how fast, and that comes down to fibre length and construction, not price.
Which fabrics pill most
- Acrylic and polyester fleece — the most prone. Synthetic staple fibres are short, and synthetics are strong enough that the pill does not break off; it stays attached and accumulates.
- Wool blends — pill early, then settle. The pills tend to fall away on their own.
- Cotton — pills least. Long-staple cotton in a tight weave barely does it at all, and cotton pills break off easily.
- Faux fur and chenille — do not pill in the usual sense. They mat instead, which is a heat problem, not a friction one.
Counterintuitively, strong synthetic fibre makes pilling worse. On a weaker natural fibre the pill snaps off and disappears.
Preventing it
- Wash inside a duvet cover. The single most effective thing. It cuts friction against the drum and against everything else in the load.
- Skip the dryer. Tumbling causes more pilling than washing does. Air drying is where most of the benefit is.
- Wash less often, on gentle. Throws rarely need weekly washing. Every cycle is friction.
- Turn it inside out if the blanket has a clear face and back.
- Do not overload the machine. Crowded loads mean more rubbing against everything else.
Fixing it
Use a fabric shaver. A battery shaver with a mesh guard, moved in short strokes in the direction of the nap. It costs about fifteen dollars and works on every fabric here.
Do not use scissors. They cut the pile unevenly and leave a visible bald patch that is worse than the pills were.
A sweater comb or a fine-tooth comb works on loose knits where a shaver might catch. For a very loose knit, pick the pills off by hand rather than risking a blade near the yarn.
When pilling is actually a defect
Pilling in the first few weeks of normal use is expected on acrylic and fleece. What is not normal:
- Pilling on cotton within a few washes — that suggests short-staple fibre in a loose weave.
- Holes or thinning where pills were removed — the fabric was too loosely constructed.
- Matting on faux fur — that is heat damage, not pilling, and it is not reversible. See the care guide.
