Abstract
Disclosed is an optical-modulation object, including birefringent island-in-the-sea yarns, whose island portions are grouped, based on two or more spinning cores, in a matrix. The optical-modulation object causes formation of an optical modulation interface between island portions and sea portions, thus maximizing optical modulation efficiency, as compared to conventional birefringent island-in-the-sea yarns.
