A process for combining single color feed yarns, either dyed or melt pigmented, without twisting or heat-setting, to form an apparent space-dyed yarn product. The process includes the sequential steps of individually and simultaneously drawing two or more pre-spun, pre-colored singles yarns, at least one of which is differentially colored with respect to the other yarns; individually and simultaneously texturing the two or more yarns; individually and simultaneously entangling the two or more textured yarns in a first air-jet entangling process to form respective two or more entangle-sequenced yarns each having sequences of entangled and unentangled fibers; together air-jet entangling the two or more sequences of entangled and unentangled fiber yarns in a second air-jet entangling process to form a final apparent space-dyed yarn; and winding up the final apparent space-dyed yarn.
A non-twisted, non-heat set, continuous filament apparent space-dyed yarn comprising at least a first and second singles yarn, said first singles yarn having a different color than said second singles yarn, said first and second singles yarn being individually textured and being individually entangled, and after being individually entangled, said singles yarns being entangled together with sequences of entangled and unentangled sections, wherein said entangled and unentangled sections are each on the order of about 2 to 5 meters in length.
