No, centrifuging clothes in a plain washing machine is not the same as "tumble dry." These are two different processes that serve different purposes in the laundry cycle.
Centrifuging in a Washing Machine: After the washing machine completes the wash cycle, it goes into the spin cycle, also known as the centrifuge cycle. During this phase, the washing machine rapidly spins the drum containing the wet clothes to remove excess water from them. The high-speed spinning forces water out of the clothes and into the drainage system. This helps reduce the drying time required after the wash is complete and makes the clothes less damp when taken out of the machine.
Tumble Dry: Tumble dry refers to the process of drying clothes in a separate appliance called a clothes dryer, also known as a tumble dryer. A tumble dryer is specifically designed to dry clothes by tumbling them in a heated drum. The dryer uses hot air to evaporate the moisture from the clothes, and the tumbling action helps prevent clothes from clumping together, promoting even drying. Tumble dryers have various settings for different fabrics and levels of dryness.
In summary, centrifuging in a washing machine is a step within the washing process that removes excess water from clothes, whereas tumble dry is a separate drying process performed in a clothes dryer to completely dry the clothes using heated air and tumbling action. Many people use both the washing machine's spin cycle and a clothes dryer to efficiently wash and dry their laundry. However, some individuals also prefer to line dry clothes or use other drying methods to conserve energy or preserve the fabrics.
