摘要

A method of continuously wet heat treating a cloth at an elevated pressure in the steamer body of a high pressure steamer maintained at a high temperature and pressure steam with the steam body having a said mechanism, including heating a treating solution in a treating solution application tank provided outside of the steamer body with the use of steam exhausted out of the seal mechanism of the steamer body, soaking a cloth to be treated with the thus heated treating solution up to the core part thereof, drying the cloth soaked with the treating solution by evaporating water therefrom, and then wet heat treating the resultant cloth in the high pressure steamer.
