Dealing with Pilling on Knits
Those little bobbles that gather on jumpers and soft fabrics are called pills, and they are normal rather than a sign of a bad garment. Knowing why they form makes them easy to prevent and remove.
What pilling actually is
Pilling is the name for those small balls of fibre, often called bobbles, that gather on the surface of knits and soft fabrics. They form where loose fibres work their way to the surface and tangle together into little knots under the friction of wear. It is one of the most common and most misunderstood things that happen to clothes.
The first thing worth knowing is that pilling is normal. It happens to many fabrics, including good ones, and does not mean a garment is poorly made or ruined. Better still, pills are usually easy to remove, so a bobbled jumper can be restored to looking fresh in minutes.
Why it happens
Pills form through friction. Wherever a fabric rubs, against itself, against a bag strap, against a seatbelt or another garment, the surface fibres loosen and roll up into little balls. This is why pilling appears most in the places that rub most.
- Under the arms and along the sides, where the body moves against itself.
- Where a bag or strap sits and drags across the shoulder.
- On cuffs and around the waist, which meet other surfaces constantly.
Pilling clusters exactly where friction is greatest. If you know where a garment rubs, you know where the bobbles will appear.
Understanding this makes prevention straightforward: reduce the friction, and you reduce the pilling.
Removing pills the right way
Removing pills is satisfying and quick, and there are a few good methods. The key is to work gently on a flat surface so you lift the pills without harming the fabric beneath.
A dedicated fabric shaver or de-pilling tool is the easiest option, gliding over the surface and cutting the pills away cleanly. A fabric comb, drawn lightly across the fabric, catches and lifts pills for a more careful, controlled result on delicate knits. Whichever you use, lay the garment flat, work in one direction, and go lightly rather than pressing hard, which risks catching the weave.
What to avoid
Some quick fixes do more harm than good. It is tempting to pull pills off by hand or snip them with scissors, but both can damage the fabric. Pulling can drag out a length of yarn and weaken the knit, while scissors can nick the surface and cut a hole. A little patience with the right tool is far safer.
- Do not yank pills off, as this can pull and thin the yarn.
- Do not snip at them with scissors, which risks cutting the fabric.
- Do not scrub hard with an abrasive tool, which can damage the weave.
Gentle, deliberate removal keeps the garment sound while making it look new again. It helps to work in good light on a firm, flat surface, so you can see the pills clearly and keep the fabric taut rather than bunched, which is where accidental nicks tend to happen.
Preventing pills in the first place
Since pilling comes from friction, you can slow it down with a few habits in how you wear and wash a garment. Reducing rubbing during laundering makes a real difference, because the tumble of a wash is one of the biggest sources of surface friction.
Turn knits inside out before washing, so the friction falls on the inside rather than the visible surface. Wash them gently, on a soft cycle in cool water, and avoid crowding the machine, which increases rubbing. Air drying rather than tumbling also spares the surface. In wear, being mindful of where bags and straps drag can reduce the worst of it.
Fibre and pilling
Different fabrics pill to different degrees, and knowing this helps set your expectations when choosing. Fabrics with shorter or looser fibres tend to pill more, because those fibres escape the surface more easily, while tightly spun, longer-fibre fabrics hold together better and pill less. A denser, firmer knit generally resists bobbling more than a loose, fluffy one.
This does not mean avoiding fabrics that pill, since some of the softest and most comfortable knits are also the ones that bobble. It simply means knowing that a soft, fuzzy jumper may need occasional de-pilling to stay looking its best, and that this is upkeep rather than a fault. Keeping a de-pilling tool somewhere handy makes the whole thing effortless, so you can lift a few bobbles the moment you notice them rather than letting a favourite jumper slide from fresh to tired. Armed with the right tool and a little care, you can keep any knit looking fresh, and pilling becomes a minor, manageable part of owning clothes you love.
