ABSTRACT:
A modification to atmospheric dye machines, in which the modification increases the attainable operating temperatures to a level in which polyester textiles can be successfully dyed. The modification is accomplished by relocating steam injection to a location which takes advantage of venturi principles and harnesses the slight pressurization obtained by injecting steam into the liquor. The combination increases circulation of dye liquor, convective heat transfer and minimizes the formation of isothermal layering of the dye liquor. Dye liquor subject to reheating is drawn from the tank bottom, further decreasing the amounts of cooler dye liquor which may still collect within the tank.
