Abstract
A luminescent yarn and a manufacturing method thereof. The luminescent yarn is a multilayered structure, a cross-section of the yarn includes a main body and at least one luminescent surface layer having multiple luminescent particles and positioned on at least one surface of the main body. Accordingly, the luminescent surface layer is positioned on the surface of the luminescent yarn to directly absorb energy and emit luminescence, whereby the luminescent yarn has better luminance and longer luminescence-emitting time. The manufacturing method of the luminescent yarn includes steps of: manufacturing a film material, the film material having a substrate material and at least one luminescent layer disposed on at least one surface of the substrate material; and cutting the film material to form the luminescent yarn.
