Storing rinsing water for textile dyeing process - using a tank in which it is heated for re-use by heat exchanging with new rinsing water

摘要

Textile material is dyed in a dyeing chamber and after the dye has been removed the textile material is rinsed with water. After the first rinsing process the rinsing water is pumped into a first supplementary reservoir via e.g. a three way valve. New rinsing water may be pumped into the dyeing chamber for the second rinsing operation via e.g. a heat exchanger and the used rinsing water is heated by being pumped via the heat exchanger from the first supplementary reservoir into pref a second supplementary reservoir. The used rinsing water from the second supplementary reservoir is then fed back into dyeing chamber to execute a third rinsing operation. Less rinsing water is used, and less dye contaminated rinsing water has to be disposed of.
