1. A PROCESS OF LOW TEMPERATURE DYEING OF WOOL, COMPRISING THE STEPS OF PLACING A PREDETERMINED QUANTITY OF WOOL STOCK IN A CONTAINER ADAPTED TO RECEIVE IT; WETTING THE SAID WOOL STOCK WITH A PREDETEREMINED QUANTITY OF WATER AT A SELECTED TEMPERATURE BELOW 150*F.; ADDING A PREDETERMINED QUANTITY SUBSTANTIALLY LESS THAN 1% BY WEIGHT ON THE WEIGHT OF THE WATER OF A DYE ASSISTANT COMPOSED AT LEAST IN PART OF ETHYLENE GLYCOL AND AT LEAST ONE NONYLPHENOL POLYOXYETHYLENE ETHANOL SURFACTANT; ADDING A PREDETERMINED QUANTITY OF ACETIC ACID; ADDING A PREDETERMINED QUANTITY OF DYESTUFF AT THE SAID SELECTED TEMPERATURE LESS THAN TEN MINUTES AFTER THE WETTING OF THE SAID WOOL SOCK HAS BEEN COMPLETED; RAISING THE TEMPERATURE OF THE DYEBATH COMPOSED OF THE SAID WATER, THE SAID DYE ASSISTANT, THE SAID ACETIC ACID, AND THE SAID DYESTUFF, TO A PREDETERMINED POINT BETWEEN 160*F. AND 185*F. DURING A PERIOD OF LESS THAN FORTY-FIVE MINUTES; MAINTAINING THE SAID DYEBATH AT THE SAID PREDETERMINED TEMPERATURE POINT FOR LESS THAN THIRTY MINUTES MORE; AND RINSING THE SAID WOOL STOCK SO THAT THE SAID WOOL STOCK RETAINS A PREDETERMINED SHADE OF DYE WITH SUBSTANTIAL FASTNESS.
