Abstract
Abstract The disclosure embraces a method of dyeing and an apparatus comprising a horizontally extending generally cylindrical article dyeing vessel which is provided with a bank of nozzles extending along the interior bottom wall portion of the vessel; the nozzles are disposed to discharge liquid in a generally tangential direction with respect to the interior of the vessel; the nozzles are divided into groups each of which is connected to the out-put of a pump through one or more conduits. The conduit or conduits which deliver fluid to the nozzles are provided with a valve means so that the output of the nozzles can be controlled whereby a substantially uniform, circular fluid flow may be obtained. The vessel is provided with a suction liquid outlet slot on one side of the nozzles opposite the direction of fluid delivery and which extends the length of the vessel to enable the vessel to handle variably sized loads. A large unloading valve is provided to enable the vessel to be rapidly emptied and fluid nozzles are arranged on the interior of the vessel to flush articles out through the unloading valve.

A METHOD OF UNIFORMLY DYEING A PLURALITY OF DISCRETE REACTED WITH CONCENTRATED PHOSPHORIC ACID FOLLOWED BY REACTION WITH AN ALKYLENE POLYAMINE. TEXTILE ARTICLES IN A DYE VESSEL OF THE TYPE HAVING A SUBSTANTIALLY CYLINDRICALLY SHAPED INTERIOR WALL WITH A HORIZONTALLY DISPOSED LONGITUDINAL AXIS AND SPACED APART END WALLS, AT LEAST ONE ROW OF NOZZLES ARRANGED TO DISCHARGE LIQUID IN A GENERALLY TANGENTIAL DIRECTION WITH RESPECT TO SAID INTERIOR WALL, A CLOSABLE LOADING PORT AND CLOSABLE UNLEADING PORT, CONDUIT MEANS FOR SUPPLYING LIQUID TO SAID ROW OF NOZZLES, MEANS FOR CONTROLLING THE TEMPERATURE OF THE LIQUID SUPPLIED TO SAID ROW OF NOZZLES, INCLUDING MEANS FOR CIRCULATING SAID LIQUID THROUGH ADJUSTALBE HEAT TRANSFER MEANS, MEANS FOR CONTROLLING THE RATE OF FLOW OF THE LIQUID THROUGH SAID CONDUIT MEANS, THE METHOD COMPRISING THE STEPS OF: SUPPLYING A LIQUID UNDER PRESSURE THROUGH SAND ROW OF NOZZLES TO THE INTERIOR OF SAID VESSEL TO SET UP A SUBSTANTIALLY CIRCULAR FLOW ABOUT SAID LONDITUDINAL AXIS OF THE LIQUID AND ARTICLES TO BE DYED, HEATING SAID LIQUID TO A FIRST PREDETERMINED TEMPERATURE, SUPPLYING A DYE MATERIALS THROUGH SAID ROW OF NOZZLES WHILE MAINTAINING THE CIRCULAR FLOW OF THE CONTENTS OF SAID VESSEL, HEATING THE CONTENTS OF SAID DYE VESSEL TO A SECOND PREDETERMINED TEMPERATURE THAT IS HIGHER THAN SAID FIRST TEMPERATURE BY PASSING THE LIQUID CONTENTS OF SAID VESSEL THROUGH SAID HEAT TRANSFER MEANS, MAINTAINING THE CIRCULAR FLOW IN SAID VESSEL UNTIL THE DYE MATERIAL IS EXHAUSTED, COOLING THE CONTENTS OF SAID VESSEL TO A PREDETERMINED TEMPERATURE BY PASSING THE LIQUID CONTENTS OF SAID VESSEL THROUGH SAID HEAT TRANSFER MEANS, AND SUBSEQUENTLY UNLOADING THE ARTICLES AND LIQUID IN SAID VESSEL THROUGH SAID UNLOADING PORT.

Claim 5
Dependent Claim
55 words
The method as claimed in claim 1 wherein a liquid outlet is provided adjacent said row of nozzles in said wall of said vessel and including the step of reversing the direction of liquid flow in said vessel, subsequent to the cooling step, by supplying liquid to the interior of said vessel through said outlet.
Claim 6
Dependent Claim
31 words
The method as claimed in claim 1 including the step of placing the contents of said vessel under a predetermined pressure subsequent to the step of supplying a dye material thereto.
