Abstract
Textile material to be dyed is circulated through a dyeing machine containing a hot liquid dye bath in such manner that the material repeatedly is immersed in and removed from the dye liquor. Following removal of the material from the dye liquor it is subjected to treatment by air to remove surplus liquid from the material prior to the return of the material to the dye liquor. Following its final removal from the dye liquor the material is cooled by being sprinkled with water at a temperature lower than that of the dye liquor.
