Bulky laundry items such as comforters, jackets, and thick towels are usually not fully dried after going through a dryer. This is due to the way these objects dry: the exterior dries while the interior remains damp. When they tumble, the material becomes compressed, limiting air circulation and trapping moisture within it. Nature Scientific Reports suggests that placing tennis balls in the dryer is an easy way of addressing this issue. They bounce around through the fabric's layers, creating spaces for improved air circulation. It allows heat to move through these layers better, preventing moisture from getting trapped in different spots. The solution is simple yet effective, grounded in the nature of airflow within a compacted material.
It is important to break the fabric clumps
Another problem associated with drying large articles is clumping, according to ScienceDirect. The fabric folds on itself and stays in such a form for a long time during the drying period. This forms clusters in which air has difficulty reaching. The tennis balls become continuous disrupters inside the drum. They keep breaking the folds and separating layers when colliding with the fabric. This ensures that the fabric does not settle in tight clumps, making it easy for heat to penetrate deep inside. The process is not continuous but occurs intermittently throughout the drying cycle. With time, this helps reduce drying time and improves results. Rather than depending on rotating motion only, additional motions introduced by the tennis balls create variations.A more practical alternative?
Dryer balls sold commercially are created to produce the same effects; however, tennis balls may be considered an effective alternative because of their accessibility. They are available in most homes, and even used ones may work fine for that purpose. The softer surface of tennis balls is gentler than that of hard plastic dryer balls, which may be irritating due to their rough surfaces. Although tennis balls are noisy, this inconvenience does not diminish their efficiency too much. In addition, the use of tennis balls is consistent with the general tendency to make household use of common items rather than buy special appliances.Image Credit: Gemini
