Abstract
Jeans are bleached by rotating glass-expandable ceramics having a bulk specific gravity of 0.7 to 1.2, a 24 hour water absorption of not greater than 5% and the maximum diameter of not greater than 150 mm, water and jeans in a rotary tank. Further jeans are bleached by rotating an air-permeable ceramic porous material having a bulk specific gravity of 0.7 to 1.9, a 24 hour water absorption of 10 to 40% and the maximum diameter of not greater than 150 mm, water and jeans in a rotary tank. In this case, the air-permeable ceramic porous material may also be immersed in a bleaching agent solution.
