Flannel bedding pilling? What’s normal – and what’s not

In short: New Flannel bedding shedding is not a defect, but the result of the napping process: Loose fiber ends come loose during the first three to five washes, after which the fabric settles. Wash it before the first night, separately and without fabric softener. biberna makes its Flannel at 160 g/m² according to the original 1968 recipe.

When Flannel bedding sheds, it is the first shock for many customers after unpacking: fine lint on the pajamas, a light fluff in the lint trap, small fibers on the dark carpet. The good news upfront – this is not a quality defect, but the logical consequence of the very property for which you bought Flannel. As the inventor of Biber bedding (brushed cotton flannel), we will explain what happens in the fabric, how long the shedding lasts, and what steps you can take to significantly reduce it.

Why Flannel bedding sheds in the first place

Flannel is a cotton fabric whose surface is napped after weaving. During napping, fine fiber ends are pulled out of the yarn and stand up. These upright fiber tips form the soft, airy layer of fluff that makes Flannel so warm: they hold millions of tiny air pockets, and air is the best insulator. Our Flannel weighs around 160 g/m² – a rich, dense fabric with very high loft.

Napping inevitably also creates fibers that are only loosely held in the surface. They come loose during the first weeks of use and washing – that is the fluff you see. A fabric that does not shed at all either has no napped surface (then it is not Flannel) or contains synthetic fibers that make it feel harsh. In short: a little lint at the beginning is the price of real coziness. Read more about the construction of the fabric in our post What is Flannel bedding?.

How long does new Flannel bedding shed?

As a general rule, the shedding decreases significantly after the first three to five washes and almost completely disappears after that. What you find in the lint trap during this phase are the excess, loosely incorporated fibers. Once this excess is gone, the fluff layer remains stable – and the bedding gets softer rather than thinner with every wash. However, this requires a good basic quality with long, well-twisted cotton yarns. Short, poorly twisted fibers continuously slip out of the yarn – and then the shedding never stops.

And this is exactly the difference between original quality and cheap goods. Because stationary retailers have replaced high-quality Flannel qualities with cheaper alternatives in many places for price reasons, many people now consider permanent shedding to be normal. It is not. As the inventor of this quality, we make our Flannel according to the original 1968 recipe – 100% cotton, napped on both sides. This depth of manufacturing is the reason why our Flannel settles after the initial phase.

Which napped quality sheds like what – and how much does it cost?

How much fluff you see in the first few weeks depends on how heavily the surface has been napped and how well the yarns are twisted. Here is an overview of our napped cotton qualities – all four made from 100% cotton:

Quality	Surface and lint behavior	Ideal for	Price range
biberna Fine flannel (0006722)	Napped original quality at around 160 g/m² with very high loft: visible fluff in the first three to five washes, after which the fabric settles	Those who want real fluff in original quality	from approx. €49.95
Castell Fine flannel (0030988)	Napped cotton from our entry-level brand Castell, plain solid color: as with any napped fabric, the excess fibers come loose in the first few washes	Guest bed, second set, small budget	from approx. €25.95
biberna Melange-Flanell (0840500)	Our own further development of Flannel, even fluffier and softer to the touch, mottled look – here too, the excess fibers come loose at the beginning	Those who love the cold and everyone looking for the finest feel	from approx. €49.95
Castell Edelflanell (0080447)	Double-napped cotton in a 135x200 + 80x80 cm set, bold designs: initial phase like Fine flannel	Entry into warm winter bedding	approx. €29.95

If you want no fluff at all, choose a smooth-woven fabric without napped fabric – our Renforcé releases practically no fibers, but warms significantly less in winter.

5 tips: How to get shedding under control

1. Wash the bedding before the first night. The first wash removes most of the loose excess fibers – before they end up in your bedroom. For more details, see our guide Washing Flannel bedding – what temperature?.

2. Wash Flannel separately and inside out. Flannel releases lint and attracts it at the same time. Therefore, do not wash it with dark terry or fleece, but separately – and turn the pillowcases inside out to protect the napped side.

3. Avoid fabric softener. Fabric softener forms a film around the fibers, clogs the fluff layer, and ultimately takes away the very loft you bought Flannel for. Flannel gets soft all on its own.

4. Use the dryer – short and gentle. Flannel handles the dryer well. One cycle on the delicate setting raises the fibers again and reliably sends loose lint to the lint trap instead of into your bed. Empty the trap after every cycle.

5. Do not overload the machine. If the drum is overfilled, the textiles rub against each other more – releasing more fibers than necessary. Two-thirds full is ideal.

Shedding or pilling – they are not the same

It is important to distinguish: shedding is loose fibers that come loose from the fabric. Pilling is the small, solid little balls that form when loose fibers entangle into little balls and stick to the fabric. Pure cotton like our Flannel is much less prone to pilling than mixed fabrics with synthetic fibers, because the rubbed-off cotton fibers simply come loose during washing instead of sticking together. Read what helps against little balls under Bedding pilling and shedding.

If you like it even fluffier and at the same time even finer: our Melange-Flanell – developed by us and exclusively manufactured by us worldwide – is the further development of Flannel. Softer, gentler to the touch, also made from 100% cotton, at the manufacturer's direct price from around €49.95. If you prefer it smooth and lightweight all year round, you will find the low-shedding alternative in Renforcé.

Frequently Asked Questions

Is shedding a reason for a complaint?
Not in the initial phase – the release of excess fibers is typical for the material. However, if your Flannel bedding continues to shed heavily after five washes or the surface becomes visibly thin, it indicates inferior yarns. In that case, please contact us.

Do vinegar or baking powder help against lint?
No. Neither addresses the root cause and can additionally stress the fibers. Only separate washing, a mildly dosed detergent without fabric softener, and a short dryer cycle are effective.

Does Fine flannel shed less than Flannel?
Tendency yes, because Fine flannel is lighter and less heavily napped – but it also warms less. You can find the comparison under Fine Biber Flannel or Flannel?.

Why should I wash Flannel bedding separately and inside out?
Because Flannel releases lint and attracts it at the same time. Therefore, do not wash it with dark terry or fleece, but separately. In addition, turn the pillowcases inside out to protect the napped side. Only fill the drum two-thirds full, otherwise the textiles will rub against each other more.

What is the difference between shedding and pilling?
Shedding is loose fibers that come loose from the fabric; pilling is small, solid little balls that form when loose fibers entangle into little balls and stick to the fabric. Pure cotton like Flannel is much less prone to pilling than mixed fabrics with synthetic fibers, because rubbed-off cotton fibers simply come loose during washing.

The most important things in brief

• The shedding of new Flannel bedding is caused by loose fiber ends from the napping process and is not a quality defect.
• After three to five washes, the shedding decreases significantly and almost completely disappears after that.
• Washing before the first night, washing separately inside out, avoiding fabric softener, and a short dryer cycle noticeably reduce the lint.
• Permanent shedding indicates short, poorly twisted yarns – a characteristic of cheap goods, not real Flannel.
• biberna makes its Flannel at around 160 g/m² according to the original 1968 recipe – 100% cotton, napped on both sides.

Conclusion: A little fluff at the beginning is part of Flannel, permanent shedding is not. Those who opt for original quality will have a fabric after a few washes that remains cozy for years. Browse our entire bedding selection now – original quality directly from the manufacturer, always.
