Why some T-shirts pill

Short answer: Pilling happens where fabric rubs against something else. Under the arms, on the stomach from a bag strap and on the back from a chair are the usual places. It is a sign of friction, not necessarily of poor quality.

Friction forms the bobbles

All knitted fabrics have short, loose fibre ends on the surface. When the fabric rubs against something, those ends roll together into small balls that stay attached. It happens in every material, including bamboo sweat clothes, but mostly where pressure and movement meet, such as under the arms or by a bag.

The usual places

Look at where the pilling sits and you can often see the cause. Under the arms, the sleeve rubs against the body with every step. On the stomach or hip there is a bag strap or a belt. On the back it is the chair or a backpack. Switching which shoulder carries your bag spreads the wear.

Remove them, do not throw it out

A fabric shaver takes the bobbles off in a minute, and the T-shirt looks almost new again. Lay the fabric flat on a table, hold it taut with one hand and move the shaver lightly in small circles. Do not press hard. This works for every style in the most popular styles.

How to limit them

Wash the T-shirt inside out so the outer side does not rub against other clothes in the drum. Skip the tumble dryer, which wears the surface more than a washing line. Do not wash it with Velcro, zips or rough fabrics like denim. See also the care advice for the bamboo sweatshirt for women.

A full drum does not help

Many people fill the machine to save water and power. But the more clothes in the drum, the more they rub against each other. For soft T-shirts, a half full machine on a gentle programme is best. That gives the clothes room to move in the water.

New pieces pill most at first

It is normal for a new T-shirt to pill the most in the first weeks. The loosest fibre ends come up first. After a few washes and one round with the shaver, the amount usually drops noticeably. It is not a sign that the fabric will keep pilling at the same rate.

What not to do

Avoid picking the bobbles off with your fingers or pulling at them, as that draws more fibres out of the fabric. Do not use scissors or a razor directly on a thin fabric either, since it can easily make holes. A proper fabric shaver or lint brush is safer and gentler.

Pilling and lifespan

A T-shirt with pilling is not worn out. The fabric is still whole, and after a quick treatment it looks neat again. Many T-shirts therefore have a long life even after pilling several times. Only when the fabric turns thin or see through in the exposed spots is it time to consider a new one.

Frequently asked questions

Is pilling a sign of poor quality

No. It is first and foremost a sign of friction. Even expensive fabrics pill where a bag or strap presses against the body all day.

Does pilling come back after removal

Yes, but usually less, because the loosest fibre ends are already gone. After a few rounds of washing and shaving, the surface calms down and stays neater.

Can you prevent it completely

No, but the right washing and less friction from bags, straps and harnesses help a lot. Washing inside out and air drying make the biggest difference day to day.
