Highlighted non-blended continuous filament carpet yarn

A process for preparing moresque or berber continuous filament yarn comprising:

• (a) supplying a first group of continuous filaments under tension to a first entangling zone where the first group of continuous filaments is impinged with fluid under pressure;
• (b) subjecting the first group of continuous filaments to entangling by fluid impingement in the first entangling zone, wherein during said entangling, providing sufficiently high yarn tension and fluid pressure to create harsh nodes in the first group of continuous filaments such that after said subjecting the group has a yarn harshness of at least about 200;
• (c) supplying one or more other groups of continuous filaments which are differentially precolored or dyeable with respect to the first group;
• (d) joining the first group and the other groups after said subjecting;
• and
• (e) interlacing under tension and by the action of a fluid the tightly entangled first group with the one or more other groups of continuous filaments, said interlacing taking place under a yarn tension and fluid pressure sufficient to cohere all groups of continuous filaments without blending the tightly interlaced first group with the one or more other groups such that after said interlacing the finished yarn has node harshness less than 100.
