What is perm press on dryer?

Perm press, also known as permanent press, is a cycle on a clothes dryer designed to minimize wrinkles in clothing. It's primarily intended for wrinkle-resistant fabrics like polyester blends and cotton blends that are specifically treated to resist wrinkling. Here's a breakdown of how it works and its key features:

• Lower Heat: Perm press cycles use a lower temperature than regular cycles. High heat is the primary culprit for setting wrinkles into fabrics. The lower heat helps to gently dry the clothes without causing deep creases.

• Cool-Down Cycle: Many perm press cycles include a cool-down period at the end of the drying cycle. This helps to reduce wrinkling further by allowing the garments to cool gradually, preventing the formation of creases as they wrinkle as they cool.

• Reduced Tumbling: The tumbling action in a perm press cycle is often gentler and less vigorous than in regular or high heat cycles. Less agitation means less chance of the fabric creasing. The drum may also rotate at a slower speed.

• Air Fluff Option (Sometimes): Some dryers offer an air fluff option within the perm press cycle. This uses only cool air to fluff and refresh clothes without adding heat. This can be useful for clothes that are only slightly damp or need a freshening up without drying them completely.

• Not for all fabrics: Perm press isn't suitable for all types of clothing. Delicate items, fabrics requiring low heat (like wool or silk), or items prone to shrinkage should be air dried or dried on a delicate cycle.

In short: The perm press cycle aims to minimize wrinkles by employing low heat, gentle tumbling, and a cool-down phase. It's a useful feature for reducing ironing time and keeping wrinkle-resistant clothing looking its best.
