Abstract
A method of dyeing of short-staple fiber of cotton, synthetics or blends thereof in which the sliver if formed into a roving package on a perforated sleeve in a flyer frame with a slight twist and with a uniform winding density and the roving package is then subjected to dyeing and the dyed roving package is then delivered directly to the final spinning frame. The dyeing of the flyer slubbing is possible because of a package before final spinning, but not in the flock form with a stability of the flyer slubbing afforded by the slight twist imparted thereto in the flyer frame.
