Abstract
A wash system is provided having a rotatable wash basket for receiving fabric items disposed within an imperforate wash tub. A quantity of wash liquid is initially applied to the fabric items while the fabric items are tumbled within the wash basket until the fabric items are saturated with wash liquid and have had a chance to roll-up. The washing liquid is then extracted from the fabric items and the extracted wash liquid is stored for later use in a holding tank. A portion of the stored wash liquid is reintroduced from the holding tank to a mixing tank and mixed with detergent to form a wash liquor having a detergent concentration within a predetermined range. This wash liquor is then continuously passed through the fabric items while the wash basket rotates at a speed to maintain the fabric items against a peripheral wall of the wash basket.
