Abstract
In a method of dyeing yarn cheeses stacked on a spindle and pressed to a definite compression degree by flowing a dye liquor through the yarn layers, the dye liquor is flowed while undergoing pulsation in a minimized flow rate and a minimized flow pressure, thereby enabling even permeation of the dye liquor into yarn layers and accordingly, even dyeing.
