Why Does Cashmere Pill? Causes, Prevention and How to Remove Pills

Why does cashmere pill? It is one of the most common questions from anyone who owns a soft knit, and it is usually asked with a little alarm. You buy a beautiful cashmere sweater or scarf, wear it a few times and notice small balls of fibre forming on the surface. It is easy to assume you were sold something poor. In most cases, that is not true. Pilling is a normal behaviour of fine natural fibres, and understanding it makes it much easier to manage.

This guide explains what pills are, why cashmere is particularly prone to them, what really separates good cashmere from poor, how to remove pills safely, how to reduce them in future and when heavy pilling should make you suspicious. If you are shopping, see also our checklist on how to identify real cashmere.

What Is Pilling?

Pilling is the formation of small tangled balls of fibre on the surface of a fabric. Fabric is made of yarn, and yarn is made of many short fibres twisted together. Some fibre ends always work loose at the surface. When those loose ends rub against each other, or against something else, they tangle into small balls that stay attached to the fabric by a few anchoring fibres. Those balls are pills.

Pilling is not a defect in the sense of a manufacturing fault. It happens in nearly every fabric that is made from short, staple fibres, including cotton, wool, cashmere and many synthetics. It is a matter of degree and of how the pills behave afterwards.

Why Cashmere Is Prone to Pilling

Several qualities that make cashmere lovely also make it prone to pilling.

Fine fibres

Cashmere fibres are very fine, which makes them soft. Fine fibres are also more flexible, so they tangle easily when loose ends rub together. Coarser fibres are stiffer, and so they tend to poke out and break off rather than knit into pills.

Short fibres and loose ends

When fibre is short, more ends stick out of the yarn surface, and there are more opportunities for pills. Longer fibres are twisted more securely into the yarn and produce fewer loose ends.

Soft spinning and loose construction

A softly spun yarn or a loosely knit or woven fabric feels lovely and drapes well, but it leaves fibres freer to migrate to the surface. Many of the softest cashmere pieces are made this way.

Friction

Pilling occurs where fabric is rubbed: under the arms, at the cuffs, on the sides of a sweater where arms brush against the body, where a bag strap or seatbelt presses, and on scarves that rub against a coat collar. The more friction, the more pills.

The break-in period

New cashmere often pills more in the first few wears, because loose short fibres work their way to the surface and are removed. After they are combed off, the fabric usually settles and pills much less.

Does Pilling Mean Poor Quality?

Not necessarily. Some pilling is normal even in very good cashmere. What matters is how much and how fast.

Signs of good cashmere that pills lightly:
- A modest number of pills in the first few wears at friction points.
- Pills that come off easily and do not return in large numbers.
- A fabric that remains dense and even after de-pilling.

Signs of poor quality:
- Heavy pilling almost immediately, even on areas that are not rubbed.
- Pills that are tight, hard and form continuously.
- Thinning or bald patches where pills have been removed.
- A fabric that feels lifeless or limp after a few wears.

Heavy pilling in the first week usually points to short fibres, low-grade yarn or a blend with lower-quality fibres. Our article on cashmere quality explained describes what separates long-lasting cashmere from disappointing cashmere, and our comparison of cashmere vs merino wool explains why merino generally pills less.

How to Remove Pills From Cashmere

Remove pills gently. Aggressive handling removes fibre from the fabric itself and causes thinning.

Method 1: A cashmere comb

A cashmere comb is a fine-toothed tool designed for the job.

1. Lay the garment flat on a smooth, firm surface.
2. Hold the fabric taut with one hand.
3. Use light strokes with the comb in one direction, following the weave.
4. Empty the comb regularly.
5. Finish by smoothing the surface with your hand.

It is gentle, effective and inexpensive.

Method 2: A fabric shaver

A battery-powered fabric shaver cuts pills from the surface. It is quick, but use it with care.

1. Lay the garment flat and keep the fabric stretched slightly.
2. Move the shaver lightly in small circles without pressing.
3. Do not linger in one place, which can cut into the fabric.
4. Stop if you see the weave beneath the pills.

Method 3: A pumice-style stone

Some people use a fine pilling stone. Move it gently over the surface. It works, but it is less controlled than a comb.

What not to do

• Do not pull pills off by hand. Pulling drags anchoring fibres out of the fabric and creates weak spots.
• Do not use scissors on the surface except to carefully snip a single large pill.
• Do not use razors. They cut too easily and can damage the weave.
• Do not de-pill a wet or damp garment. Fibres are weaker when wet.

How to Prevent Pilling

You cannot stop pilling entirely, but you can reduce it considerably.

• Rotate your pieces. Wearing the same sweater every day accelerates wear.
• Rest between wears. Rest lets fibres recover.
• Avoid friction points. Choose a bag with a soft strap or carry it on the opposite shoulder from your best scarf. Avoid rough jewellery or velcro near knitwear.
• Wear a smooth lining or layer under a cashmere sweater, such as silk or fine cotton, to reduce rubbing against rougher garments.
• Avoid wearing cashmere under rough coats or backpacks.
• De-pill regularly and lightly. Frequent gentle combing is better than an occasional harsh treatment.
• Wash carefully or dry clean. Rough washing increases pilling. Follow the label and read how to care for cashmere.
• Fold instead of hanging. Hanging stretches fibres and can make them loosen.
• Store clean and covered. See how to store woollens and prevent moth damage.

Does Washing Make Cashmere Pill More?

Rough washing does. Agitation, hot water and harsh detergents roughen the fibres and encourage loose ends to tangle. Gentle hand washing in cool water with wool detergent, or dry cleaning, minimises the risk. Never tumble dry.

At VANYRA ATELIER, our pieces are labelled dry clean only, and we recommend choosing a cleaner experienced with fine natural fibres.

Pilling in Different Types of Cashmere Pieces

Sweaters

Pills are most common under the arms and on the sides. Wear with care and de-pill regularly. The Ashfield Sweater rewards this kind of routine attention.

Scarves and wraps

Pills gather where the fabric rubs against coats and collars. Loosely woven pieces pill less than loosely knitted ones because the yarn is more securely held in the weave. See our advice on how to wear a shawl to reduce friction.

Throws and cushions

These generally see less friction, so pilling is usually mild.

Is Hand-Loomed Cashmere Less Likely to Pill?

Pilling depends mostly on the fibre, the yarn and the structure of the fabric. Hand-loomed cashmere woven from long, well-spun yarn in a balanced weave typically pills less than cashmere made from short, weak fibres. The loom by itself does not guarantee low pilling, but careful handling of fine yarn on a handloom, together with good materials, produces stable fabric. Our comparison of handloom vs powerloom fabric explains this in more detail.

When to Be Concerned

Contact the seller if:

• The piece pills heavily within its first few wears.
• Pills form across the whole surface, not just at friction points.
• The fabric becomes visibly thin after normal de-pilling.
• The label or the feel suggests a fibre other than what you paid for.

A reputable maker will discuss the issue openly. If you own a VANYRA ATELIER piece and have a concern, contact our team.

Frequently Asked Questions

Why does my new cashmere sweater pill?

New cashmere often pills in the first few wears as loose short fibres work their way to the surface. Removing them gently usually settles the fabric.

Does pilling mean my cashmere is fake?

No. Pilling is a normal behaviour of fine natural fibres. Excessive, rapid pilling can indicate lower-quality fibre, but light pilling alone does not mean the cashmere is fake.

How do I remove pills from cashmere without damaging it?

Lay the piece flat and use a cashmere comb or a fabric shaver with light strokes. Do not pull pills by hand or use razors.

Will pilling stop eventually?

Often, yes. Once loose short fibres have been removed, the surface usually settles and pills much less, though friction can cause new ones.

Does merino wool pill less than cashmere?

Generally, yes. Merino is a more robust fibre, and it usually pills less noticeably, although quality and construction matter greatly.

How often should I de-pill cashmere?

Lightly and regularly, whenever you notice pills forming, rather than waiting until they build up. Frequent gentle combing is kinder than occasional heavy treatment.
