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.
Claims26
An optical-modulation object for modulating light incident on a light incident surface of the optical-modulation object and emitting the light to the light incident surface of the optical-modulation object and/or an opposite surface of the optical-modulation object, the optical-modulation object comprising:
- a matrix;
- and
- a birefringent island-in-the-sea yarn arranged in the matrix,
- wherein the birefringent island-in-the-sea yarn comprises two or more groups of island portions arranged based on two or more spinning cores,
- wherein the island portions, which form one group, form spaced layers comprising three or more layers based on the spinning cores,
- wherein a maximum distance between the centers of adjacent island portions present in one group is smaller than a maximum distance between the centers of adjacent island portions present in two adjacent groups, and
- wherein spaced spaces are present between all adjacent groups, and the spaced spaces are sea components.
