Abstract: At present, desizing, scouring, bleaching and reduction steamers are equipped with the steam sealing form for continuous production of woven fabric. Compared with liquid sealing, steam sealing has the advantages of less liquid and steam using, fast speed, etc. This article discussed the effect of energysaving effect of steam sealing from the view of its principle, calculation theory, structure characteristics and comparison on using effect.

Key words: steamer; steam sealing; energy-saving; theoretical calculation
