Apparent space-dyed yarns and method for producing same

A process for producing apparent space-dyed bulked continuous filament yarn comprising the sequential steps of:

• individually and simultaneously drawing two or more pre-spun, pre-colored singles yarns, at least one of said singles yarns being differentially colored with respect to the other singles yarns;
• individually and simultaneously texturing the two or more singles yarns;
• individually and simultaneously entangling the two or more textured singles yarns to form respective two or more entangle-sequenced yarns each having fiber portions having sequences of entangled and unentangled fibers;
• together entangling the two or more entangle-sequenced yarns to form a final apparent space-dyed yarn;
• and
• winding up the final apparent space-dyed yarn, wherein the step of individually and simultaneously entangling the two or more textured singles yarns comprises:
• controlling at least one first nozzle assembly by providing to said at least one first nozzle a first pressurized air setting of a repeating on-off sequence;
• and
• the step of together entangling the two or more entangle-sequenced yarns comprises:
• controlling a second nozzle assembly by providing to said second nozzle assembly a second pressurized air setting of a repeating pressure sequence of high and low pressure, wherein said second pressurized air setting is timed such that the second nozzle assembly is at a high pressure when the at least one first nozzle is on, and at a low pressure when the at least one first nozzle is off.
