The subject of dyeing is one of intense interest and wide scope, butit is unfortunately beyond the field of this brief survey. Suffice it tosay that various chemical processes and mechanical devices are em-ployed to give a permanent color to the cloth. (Yarn and raw stockdyeing are less commonly employed in the cotton than in the woolen Dyeingand worsted industries.) 139 1. Printing Machine. Some cotton cloth is simply dyed with a solid color and finished, but Resist and frequently it is first dyed with one color and then printed with others, Discharge or with a chemical which will discharge the dye and leave white figures Printing wherever it touches the cloth. In contrast to this discharge method, where it is desired to obtain white figures on a colored back-ground, it is also possible first to print the figures with a chemical that will resist the subsequent action of the dye-stuff. Where a white ground is used and it is not essential that the colors and design appear on both sides of the cloth it is not necessary to dye at all. (40
