Multiple strands of undyed yarn are fed continuously from supply spools or bobbins supported on a creel to a skein winding apparatus. The strands each pass along a substantially horizontal path through one or more spaced dyeing stations where they are engaged by an oscillating frame and caused to oscillate laterally back and forth from said paths while streams of dye individual to the yarns are continuously directed onto the yarns from a series of overhead tubes at the dyeing stations. The strands thus periodically interrupt the dye stream of the associated tubes and receive dye at a multiplicity of spaced portions along their lengths with intervening portions of the yarns remaining uncolored. The space dyeing can be varied by changing the speed of movement of the yarns, by varying the amplitude and speed of movement of yarn guide means which produces the lateral oscillation of the yarns and by selectively operating varying numbers of dye stream feeders at one or both dyeing stations. Upon completion of the space dyeing operation, the individual skeins of yarn can be batch dyed in an overcolor.
A process for randomly coloring textile yarns in a continuous system comprising continuously transporting a plurality of spaced yarns on parallel primary transport paths between yarn supply and take-up means, reciprocating said yarns laterally at first and second spaced points while said yarns are being transported along said transport paths to cause the yarns to deviate from the primary path at said first and second points, and directing first and second streams of dye onto said yarns at said first and second spaced points, respectively, while the yarns are reciprocated.
Apparatus for randomly dyeing yarns comprising means for continuously feeding a plurality of spaced yarns on primary transport paths, means for engaging the yarn while they are moving along said transport paths including a first stationary yarn guide member and a first coacting transverse reciprocating guide member for shifting the yarns back and forth laterally of said transport paths in at least one region, said reciprocating guide member including spaced walls having guide openings for the yarns so that localized portions of the yarns are held by the reciprocating guide member in spaced parallel relationship during reciprocation of the guide member, and at least one bank of transversely spaced dye feeder tubes supported above the reciprocating guide member for directing streams of dye onto the individual yarns in said region while the yarns are being shifted back and forth laterally.
A process for randomly coloring textile yarns in a continuous system comprising continuously transporting a plurality of spaced yarns along substantially horizontal parallel transport paths between yarn supply and take-up means, reciprocating said yarns laterally at a plurality of locations spaced along the transport path between said yarn supply means and take-up means while they are moving on said transport paths and directing streams of dye onto regions of individual yarns at each said location while the yarns are reciprocated and transported.
Apparatus for randomly dyeing yarns comprising means for continuously feeding a plurality of spaced yarns on primary transport paths in a substantially horizontal plane, reciprocating guide means for shifting the yarns in said horizontal plane back and forth laterally of said primary transport paths, and spaced dye feeder means for directing streams of dye onto the individual yarns of said web while the yarns are being shifted back and forth laterally including a first and a second bank of dye stream delivery tubes positioned at spaced points along said primary transport paths with the axes of the tubes in the banks positioned to intersect the primary transport paths, guide means for engaging the yarns while they are being transported and shifted back and forth laterally of said primary transport paths and said reciprocating means including spaced walls having guide openings for the yarns so that localized portions of the yarns are held by the reciprocating guide member in spaced parallel relationship during reciprocation.
Apparatus for randomly dyeing yarns comprising means for continuously feeding a plurality of spaced yarns on primary transport paths in a substantially horizontal plane, reciprocating means for shifting the yarns in said horizontal plane back and forth laterally of said primary transport paths, and means for directing streams of dye onto the individual yarns of said web while the yarns are being shifted back and forth laterally including a first and a second bank of dye stream delivery tubes at spaced points along said primary transport paths with the axes of the tubes in the banks positioned to intersect the primary transport paths, means for continuously supplying the tubes of said banks with dye, said means comprising headers connected with the dye inlet ends of the tubes in said banks and delivery pump means connected with the headers, valve means connected to the delivery pump means to allow selective operation of one or both of said headers and said recirpocating means including a first and a second reciprocable member transverse to said primary transport paths and having a longitudinal slot aligned with said first and second bank of dye delivery tubes, respectively, and dye recovery means comprising a trough below each reciprocating member and aligned with said slot.
