Abstract

Yarns and fabrics formed from such yarns incorporating an arrangement of discrete zones of variable heat treat history thereby imparting differential dye affinity and structural character at discrete zones along the yarn length are described. The differential dye affinity permits variable shading along the yarn length when the yarn is subjected to a dye bath. Processes and equipment for manufacturing such yarns are also provided.
