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.
Claims8
An apparatus for maintaining near boiling temperatures of a textile dye liquor in an atmospheric dye machine comprising:
- a well, said well adapted to be placed at a low point of a tank of said liquor;
- a well cover, said well cover capable of allowing said liquor in said tank to pass through said well cover and collect in said well;
- a sparge tube, said sparge tube capable of directing an external supply of steam into said well, said steam heating said liquor in said well;
- a chamber, said chamber capable of collecting the heated liquor from said well;
- a spout, said spout connecting said chamber to said well, said spout providing a path for said heated liquor to follow from said well to said chamber;
- a baffle;
- said baffle separating said chamber from said tank, said baffle capable of permitting said liquor to flow from said chamber to said tank;
- and
- a chamber cover, said chamber cover adapted to be placed over said chamber, said chamber cover capable of sealing the top of said chamber to atmosphere around said chamber.
