ENERGY CONSERVATION IN TEXTILE DRYING BY SELECTION OF RINSE TEMPERATURE

In washing apparel and related articles, a cold rinse does not always conserve energy. Removal of water in spin drying becomes more complete as its temperature is raised, thus reducing the amount of costly thermal drying. When gas-heated water is used in washing followed by electric drying, total energy cost is minimized by using at least a warm rinse cycle. When the same type of energy is used in water heating and drying, no energy is saved by heating rinse water.
