Beck Dyed is a method used to dye large batches of greige goods—usually in rope form—in large becks, vats, or steel tanks. Greige goods are moved in a circular motion in and out of an aqueous dyebath to help provide color uniformity. Although typically used for solid colors, goods that are beck dyed with modified or different dye affinities can also achieve varying color or cross-dye effects.
