Heat exchanger uses of Textile

Heat exchanger uses of Textile: 

During the different stage of dyeing (also pre-treatment, after-treatment), there is a need of increasing or decreasing the temperature of dye liquor gradually, We cannot use liquor of required final temperature directly because there may be possibilities of thermal shocking of the fabric. So, the temperature should be increased or decreased in a controlled manner. This controlling is done by heat exchanger. Actually it is an indirect heater. During the circulation of dye bath liquor, the liquor passes Through the heat exchanger.
