Abstract
A mist of water and air and ozone gas is used in the finishing of fabrics of jeans and other apparel to achieve a faded, worn, or washed appearance and finish. Jeans or other apparel items are processed in a chamber of a finishing machine. Water and air mist that includes drops of liquid water are sprayed into the chamber. Ozone is separately introduced into the chamber. After processing, the jeans or other apparel will have a stonewashed or acid-washed appearance.
