If your item's label says not to tumble dry, it's best not to, even with zero heat. The tumbling movement could create wrinkles which will be hard to remove without heat. Tumbling without heat could also cause shrinkage after washing.
If a tag says “do not tumble dry,” that means you should not put the item in the dryer, regardless of the setting. Instead, follow the manufacturer's instructions. If there aren't any explicit instructions for how to dry it, play it safe and hang it up to air-dry.
The symbol means do not put in a tumble dryer, usually because the fabric will react with the heat and either shrink or possibly melt. You can spin it in a washing machine without issue.
Most dryers have a setting listed as "air dry," "air fluff," or "no-heat," which indicates the program adds no additional heat while spinning your garments. Instead of adding hot air, this cycle blows room-temperature air onto your clothes as it tumbles them.

"First, check the tags. Anything that says 'line dry' or 'lay flat to dry' can't tolerate the heat or the tumbling action of the dryer—or both," she says.
Tumble dry
Tumble dry settings can be used as an alternative to air drying to help save you time and keep your clothes ready to wear. With high heat, low heat or no heat options, tumble dry is a versatile option to get your items dry. Just remember to check your garment's care tag to make sure it can be tumble dried.
Any clothing with the tumble dry symbol, a square with a large circle inscribed in it, can go in the dryer, but some garments require a certain heat setting. (The more small black dots inside the circle, the higher the heat.)
You can put polyester in the dryer on a cool to medium setting. The dryer won't cause wrinkles, but polyester can be ironed on low or steamed. Air dry polyester or tumble dry at medium temperature. Polyester generally doesn't wrinkle.
Although not ideal, you can tumble dry cotton bedding if you use a low heat setting to prevent it shrinking and remove the items before the cycle ends (we find it's easier to shake out the creases when the sheets are still a little damp!).
Tumble dry is when you put your laundry items into the dryer instead of air-drying them. Every setting you choose when using your dryer is considered a tumble dry setting. Pretty simple, right?
What does “do not tumble dry” mean? Certain garments shouldn't go in the dryer at all. Subjected to high temperatures, silk may shrink, wool and knitwear may pill and undergarments may shrink or lose their shape.
All you have to do is to just transfer your washed clothes in the clothes dryer machine, run it on ideal setting. That's it. The entire process is easy, effortless and mess-free. And, don't worry tumbledry is good for clothes (if you do it in the right way).
The alternative to tumbling dry in an automatic dryer is hanging the clothes on a clothesline or rack to air dry. Dryers have multiple cycle and temperature settings.
A square with a large circle inside that is crossed out means do not tumble dry. A square with circle inside symbol and a single dot indicates normal machine drying on a low setting. A square with three vertical lines inside indicates to drip dry, usually by hanging a dripping wet garment on a line.
Choosing the right drying cycle
Modern tumble dryers offer various cycles to suit different fabric types and drying needs. The cotton cycle uses high heat and is perfect for towels, bedding, and sturdy cotton items. For polyester and mixed fabrics, use the synthetics cycle, which operates at medium heat.
The low heat setting can be used after washing a down comforter or to tumble dry a duvet (but do check the tags on the items to make sure this doesn't conflict with the manufacturers' recommendations). Low is around 120 to 122°F (49 to 50ºC) on Samsung tumble dryers, as an example.
The square with a circle inside is the general symbol for tumble drying. If you see it on a laundry label, your item can be tumble-dried, and it's safe to put it in the dryer. If a laundry item should not be tumble-dried, you will see the same square with a circle, but it will be crossed out.
Unlike air drying, where clothes dry through natural airflow, tumble drying uses heat and movement to reduce dry time and leave fabrics soft and wrinkle-free. It's essential to understand the different tumble dry settings on your dryer.
Tumble drying is simply machine drying rather than line drying or laying flat to dry. This method is called “Tumble Dry” because clothes tumble in the dryer drum where airflow, along with heat, dries clothes quickly. But not all fabrics are made to be tumble dried—always check the care tag first.
If you do not have any dryer, or you simply prefer the air drying, it is possible. To do so, we recommend you lay it flat on a towel in a warm area, but out of the direct sunlight. It is better that you choose a well-ventilated area, like a shady spot outdoor or an indoor area such as a laundry, for example.
