Abstract
Randomly dyed skeins of yarn are produced in an apparatus which comprises an open vat adapted to be filled with a liquid dye bath and having rack means for supporting a plurality of skeins of yarn which are to be randomly dyed. The rack means includes valved conduits to control the flow of dye therethrough. Further valve means are provided for selectively adjusting the level of the liquid dye bath relative to the skeins supported in the dye bath while maintaining the liquor ratio, i.e., the ratio of liquid dye bath to yarn dyed, constant and as low as practical.
Claims10
Apparatus for dyeing yarn comprising an open vat, yarn skein supporting means comprising upper and lower headers, each header having skein supporting arms extending therefrom in cantilevered relation thereto, valved plenum means including telescoping plenum tubes extending between said upper and lower headers and coupling said headers for selective circulation of a dye bath through one or both of said headers, said upper header being movably supported relative to the lower header to allow for variation in the spacing between the skein supporting arms of the upper and lower headers, selectively operable dye bath flow control valves in the plenum means for regulating the admission of the dye bath to both of said headers simultaneously or to one header only, said flow control valves comprising two independent sets of valves in the plenum means, one set regulating the flow of the dye bath to the upper header through said telescoping plenum tubes and the other set of valves regulating the flow of the dye bath from the plenum means into the lower header, and pump and conduit means connected to an inlet of said plenum means and to the vat to effect circulation of the dye bath.
Apparatus for dyeing yarn comprising an open vat, yarn skein supporting means comprising upper and lower headers, each header having skein supporting arms extending therefrom in cantilevered relation thereto, valved plenum means coupling said headers for selective circulation of a dye bath through one or both of said headers, said upper header being movably supported relative to the lower header to allow for variation in the spacing between the skein supporting arms of the upper and lower headers, means connected with said headers and operable to adjust the space between the headers and to lock them in selected adjusted positions and the valves of the valved plenum means including adjustable valve sets bodily mounted on said headers with said adjusting means for the headers and forming therewith a skein supporting rack unit which is bodily placeable in and removable from said vat, and cooperating guide means on the headers and vat for guiding the rack unit into and out of the vat and pump and conduit means connected to an inlet of said plenum means and to the vat to effect circulation of the dye bath.
Apparatus for dyeing yarn comprising on open vat, yarn skein supporting means comprising upper and lower headers, each header having arms extending therefrom in cantilevered relation thereto and in communication with the interior thereof, valved plenum means including telescoping plenum tubes extending between the upper and lower header coupling said headers for selectively circulating a dye bath through one or both of said headers and the associated arms, and pump and conduit means connected to an inlet of said valved plenum means and to the vat to effect circulation of the dye bath and selectively operable dye bath flow control valves in the plenum means for selectively regulating the admission of the dye bath to said headers, said flow control valves comprising two independent sets of valves in the plenum means, one set regulating the flow of the dye bath to the upper header through said telescoping plenum tubes and the other set of valves regulating the flow of the dye bath from the plenum means into the lower header.
