It Depends on the Fiber
Different materials have varying tendencies to pill:
- Wool (including cashmere, merino, alpaca) – delicate fibres are easily released, so even very expensive sweaters may pill.
- Cotton – the higher the cotton content, the lower the risk of pilling, but cotton garments can still form pills after several washes.
- Synthetic fibers (polyester, acrylic, nylon) – more prone to pilling than natural fibres.
- Blended fabrics – mixing fibers often accelerates pilling because of differences in fiber length and strength.
- More resistant fabrics – silk, viscose, linen, and denim tend to pill less thanks to their stronger fibre structure.
👉 The price or “luxury” status of a material does not guarantee a pill-free sweater. What matters most is fibre length, fineness, and structure—not whether the yarn is “expensive” or “cheap.”
Where Does Pilling Appear Most Often?
- underarms, sleeves, and sides.
- shoulders and back, under backpack straps.
- areas that come into frequent contact with other surfaces (handbags, jackets with Velcro, coarse fabrics).
How to Minimise Pilling
- Wash gently – by hand or on a delicate cycle, always inside out and ideally in a laundry bag.
- Use mild detergents – harsh chemicals weaken fibres.
- Reduce friction – avoid backpacks, rough surfaces, and abrasive fastenings.
- Rotate wear – let your sweaters rest between wears to give fibres time to recover.
How to Remove Pills
- Small scissors – carefully snip off pills, never pull them off by hand.
- Fabric shaver – the most effective and safe method for larger areas.
- Razor – can be used carefully, but risk of fabric damage is higher.

Pilling is a normal characteristic of knitwear, whether it’s luxury cashmere or everyday cotton. It’s not tied to price or quality, but rather to the natural behavior of fibres under friction. With proper care and regular maintenance, you can significantly reduce pilling, keep your sweaters looking great, and enjoy their comfort for many years.
