ABSTRACT:
This disclosure teaches a process and machine particularly suited for dyeing at a low liquid to goods ratio synthetic fibers, such as polyesters, orlon, and nylon, or blends of such with cotton, where further there are minimal risks of thermal shock, cracking, or bruising during cool down.
The disclosed apparatus has a tub enclosing the dye bath, spaced air inlet and outlet openings for the tub, and a blower for forcing air through these openings and in close proximity to the dye bath and its surface. This forced venting of the dye bath enclosure with air effectively cools the dye bath quickly but uniformly during the cool down phase of the dye cycle.
Preferably, dampers at the inlet and outlet openings can be closed to minimize the unwanted escape of vapors from the dye bath during the heat up and/or boil phases of the dye cycle; and further can be opened controlled amounts for varying the volume of airflow over the dye bath during cool down. The blower is preferably located in the system downstream of the outlet opening to create a negative pressure over the dye bath itself, which firstly reduces the flash or boil temperature of the dye bath for fast dissipation of heat from the bath, and secondly minimizes leakage of vapors from the apparatus to the nearby ambient.
