Differentially vat dyed yarns and method of making the same

Abstract

Yarns are described herein which, in some embodiments, comprise plies or single strands dyed with at least one vat dyestuff yielding a tweed or heathered appearance. In one aspect, a yarn comprises a first ply and a second ply each dyed with at least one vat dyestuff, wherein a difference in color depth (DL*) between the dyed first single strand and the dyed second single strand has an absolute value of at least 2 when the vat dyestuff is in an oxidized state. As described further herein, the first ply and the second ply are dyed in the same dyebath. In another aspect, a yarn comprises a first ply and a second ply each dyed with at least one vat dyestuff, wherein a reflectance ration between the second ply and the first ply ranges from 0.05 to 0.95.
