ABSTRACT:
A method for preventing the adhesion of scale on the sealing mechanism of a high pressure steamer in a process of continuous scouring of a long cloth therein, which comprises washing the cloth to be subjected to scouring with the use of weak acidic water with a pH of 5-6 outside of the steamer body, passing the thus washed cloth through the sealing mechanism of the steamer body, and then applying a scouring agent solution to the cloth in the interior of the steamer body. A durable sealing mechanism can be offered by preventing the damage of the sealing mechanism.
