The length of time clothes should tumble in a washing machine or electric dryer before being taken out and put on hangers to finish drying depends on several factors:
Fabric type: Different fabrics have different drying requirements. Delicate fabrics like silk or wool may require less time in the dryer, while heavier fabrics like denim may take longer.
Dryer settings: The heat and time settings on your dryer also play a role. Lower heat settings may require longer drying times, while higher heat settings can speed up the process.
Load size: The amount of clothing in the dryer affects drying time. A larger load will take longer to dry thoroughly.
Spin cycle: If you're using a washing machine before transferring clothes to the dryer, a higher spin cycle can remove more moisture, reducing drying time.
As a general guideline, you can start with a moderate drying time (around 30 minutes to an hour) for a typical load of mixed fabrics on a medium heat setting. After this initial tumble, check the clothes for dryness. If some items are already dry, take them out and hang them up to prevent over-drying, which can lead to wrinkling and potential damage to the fabric.
For delicate fabrics, it's best to err on the side of caution and check them earlier to avoid any damage. Thicker or heavier items might require longer drying times. With experience, you'll get a better sense of how long your clothes typically need in the dryer.
Remember, over-drying can cause clothes to shrink or lose their shape, and it can also consume more energy than necessary. It's always better to slightly under-dry and let clothes finish air-drying on hangers if needed.
