The principle of dyeing machine
If it is to be dyed, the large, dried uncut rolls are taken to large vats of chemical dyes, which have proven over time to provide colorfast toweling after extensive residential laundering. After being immersed in the vat, the toweling is removed and pressed between two heavy rollers which forces the dye down into the toweling. A thorough steaming sets the color. The toweling is again steam-dried, fluffed in the drying process, and then the dyed towels are ready for cutting, hemming, and labeling.
