Flannel bedding in the dryer? What your quality can withstand

In short: Flannel bedding can go in the dryer – and becomes even fluffier there, because the brushed fibers stand up again in the drum. Choose a gentle cycle at a low to medium temperature and do not over-dry the laundry. biberna invented Biber bedding (brushed cotton flannel) in 1968 and still manufactures it in Germany from 160 g/m² of pure cotton.

Can Flannel bedding go in the dryer? The short answer is: yes – and for hardly any other quality is the dryer as useful as it is here. While many fabrics suffer in the dryer, Flannel bedding even benefits from it: The brushed surface stands up again in the drum, and the fabric comes out fluffier than it went in. However, the right program and a few rules that make the difference over the years are important.

Why Flannel bedding and dryers are such a good match

Flannel is a cotton fabric brushed. It is precisely these fine, upright fiber ends that create the air pockets that provide such pleasant warmth in winter. When washed, these fibers lie flat when wet – if the fabric is then dried flat on the line, it remains somewhat flatter and initially feels firmer. In the drum, on the other hand, the fabric is kept in constant motion, the fibers stand up, and the typical fluffy feel returns.

The fact that this works has to do with the material quality. biberna Flannel weighs 160 g/m² and consists of pure cotton – a fiber that tolerates heat and mechanical movement significantly better than synthetic fibers, which quickly harden or pill in the dryer. We invented Biber bedding (brushed cotton flannel) in 1968 and still manufacture it today according to the original recipe: 100% cotton, around 160 g/m², brushed. This depth of manufacturing is the reason why our goods come out of the dryer true to size and shape-stable.

Flannel bedding in the dryer: the right program

The key is not whether, but how. These settings have proven themselves:

• Gentle cycle or "cotton cupboard dry" at a low to medium temperature. Full heat is unnecessary and the main driver of residual shrinkage.
• Do not over-dry. Take the laundry out as soon as it is dry – ideally slightly damp. Over-dried cotton becomes brittle and builds up static electricity.
• Only fill the drum halfway. Pillowcases need space, otherwise they roll up, dry unevenly, and wrinkle heavily.
• Close the pillowcases. Zip up zippers or button up buttons so that pillowcases do not get caught in the duvet cover.
• Clean the lint filter after every cycle. New Flannel bedding releases loose brushed fibers in the first few cycles – this is normal and quickly subsides.

One point that many underestimate: Avoid fabric softener. It coats the fibers in a film, flattens the Flannel exactly where it should be fluffy, and reduces absorbency. The dryer does a better job of softening anyway – completely without residue.

Which quality can go in the dryer? The overview

"Can bedding go in the dryer?" cannot be answered universally – it depends on which quality is in your machine. The following table shows which fabric benefits from the drum and which is better suited to the line.

Quality	Dryer	What the drum does	Ideal for	Price range (direct price)
biberna Flannel / Fine Flannel (160 g/m², 100% cotton)	Yes, gentle cycle	Brushed fibers stand up, the feel becomes noticeably fluffier	Winter sleepers who want maximum coziness	approx. €49.95–59.95
biberna Melange Flannel ("Flannel 2.0", 100% cotton)	Yes, gentle cycle	The already soft nap remains fluffy and gentle	Frosty sleepers and everyone for whom Flannel is still too firm	approx. €49.95–64.95
Castell Fine Flannel (entry-level price)	Yes, low setting	Same roughening effect, with lower surface weight	Second set, guest room, children's room	approx. €25.95–34.95
Renforcé (smooth plain weave)	Yes, gentle cycle	Becomes softer and wrinkles significantly less	All-year sleepers, easy-care everyday use	–
Mako Satin (sateen weave 4/1)	Better on the line	Friction in the drum takes the shine off the surface	Those who want to sleep smooth and cool	–

Specifically, this means: Those who want to sleep cozily and use the dryer are right with biberna Fine Flannel Stripes in Storm Gray & Sage (Item No. 0007253) from €49.95. It gets even softer with biberna Melange Flannel (Item No. 0840500) from €49.95. For the second set in the guest room, Castell Fine Flannel in Blackberry (Item No. 0301129) from €25.95 is sufficient.

Does Flannel bedding shrink in the dryer?

A minimal residual shrinkage is physically normal with all cotton: The fiber swells during washing and contracts slightly during drying. With high-quality, pre-shrunk goods, this is in the low single-digit percentage range and is largely complete after the first wash cycle. Therefore, do not buy one size larger – the dimensions of our bedding are designed for the finished state.

What really causes shrinkage is heat. Those who wash Flannel at 60°C and then treat it with maximum dryer heat combine two stresses. For the normal case, 40°C in the washing machine and a moderate dryer program are completely sufficient.

If you do not have a dryer

Even without a dryer, you can make Flannel soft. Shake the damp cover vigorously before hanging it up, hang it straight and not folded over the line, and shake it out once more after drying. This stands up a large part of the brushed fibers again. You do not need to iron Flannel – the brushed structure is naturally inconspicuous, and ironing heat would flatten the nap rather than smooth it.

Not every bedding quality tolerates the dryer equally well

Flannel, Melange Flannel, and terry are classic dryer candidates – here the drum noticeably improves the result. Smooth, shiny qualities like Mako Satin, on the other hand, are better suited to the line because their surface loses its shine through friction. The easy-care all-rounder Renforcé lies somewhere in between: It can go in the dryer and comes out even smoother there.

If you love Flannel but want to sleep even softer, it is worth a look at our Melange Flannel – a "Flannel 2.0" quality developed by us from 100% cotton, even fluffier and softer to the touch. Practically no one else in the world can produce this quality; in retail, it is sometimes sold for over €100, with us directly from around €49 to €79.95. To match this, you will also find Flannel fitted sheets, so that the warm feeling extends over the entire bed.

Frequently Asked Questions

Does Flannel bedding become fluffier in the dryer?
Yes. The motion in the drum stands the brushed fibers up again, which lie flat during washing. A gentle cycle at a low temperature is completely sufficient for this.

At what temperature should I dry Flannel?
Low to medium setting, "cupboard dry" or gentle drying program. High temperatures do not bring a better result, but increase residual shrinkage and fiber stress.

Why does new Flannel bedding pill in the dryer?
Roughening creates loose fiber ends that come loose in the first few washes. This subsides after a few cycles. During this time, clean the lint filter more frequently – details on this in our post Flannel Bedding Pilling – What to Do.

Can I use fabric softener if I put Flannel in the dryer?
No, avoid fabric softener. It coats the fibers in a film, flattens the Flannel exactly where it should be fluffy, and reduces absorbency. The dryer does a better job of softening anyway – completely without residue. A gentle cycle at a low temperature is sufficient.

How full can the drum be when drying Flannel bedding?
Only fill the drum halfway. Pillowcases need space, otherwise they roll up, dry unevenly, and wrinkle heavily. Also zip up zippers or button up buttons so that pillowcases do not get caught in the duvet cover, and clean the lint filter after every cycle.

Can Melange Flannel go in the dryer just like Flannel?
Yes. Melange Flannel consists of 100% cotton like our Flannel and reacts just as well to a gentle cycle. The nap remains fluffy, the feel becomes even softer.

The most important things in short

• Flannel bedding can go in the dryer and becomes fluffier there, because the brushed fibers stand up again in the drum.

• biberna Flannel weighs 160 g/m², consists of pure cotton, and has been manufactured according to the original recipe since the invention of Flannel bedding in 1968.
• Fabric softener does not belong with Flannel, because it flattens the fibers and reduces absorbency.
• Even without a dryer, Flannel becomes soft: shake it out vigorously while damp, hang it straight, and shake it out once more after drying.
• Not every quality reacts the same: Flannel, Fine Flannel, Melange Flannel, and Renforcé can go in the drum, Mako Satin is better suited to the line.
