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.

Abstract: A cutting method for an elastic membrane material and an elastic filament manufactured with the cutting method. The cutting method includes: preparing an elastic membrane material with flexibility; temporarily bonding the elastic membrane material with a cushion layer to form a semi-finished membrane material and supporting the elastic membrane material by the cushion layer; pulling the semi-finished membrane material continuously, and cutting the elastic membrane material into a plurality of filaments with a cutting device during the pulling process; and separating the cut filaments from the cushion layer, the separated filament being the elastic filament, and the elastic filament can be made into an elastic filament with functionality and special appearance. A fabric woven with the elastic filament has the effects of softness, close-fitting, excellent tactile impression and flexible.

Abstract: The present invention provides a restickable lettering film and a manufacturing method thereof. The manufacturing method of the restickable lettering film includes steps of: preparing a lettering layer having a first surface and a second surface; disposing a thermo-bonding layer on the second surface of the lettering layer; adhering the first surface of the lettering layer to a temporary adhesive layer. The lettering layer can be many times repeatedly removed from and adhered to the temporary adhesive layer. Accordingly, a user can easily use the lettering film.

Abstract: A lettering film includes a lettering layer, a middle layer and a substrate layer. The lettering layer, the middle layer and the substrate layer are separably adhered to each other. The lettering layer has cutting stripes. The lettering film can be cut into characters and/or figures. The cutting marks of the characters and/or figures cut the lettering layer and the middle layer without cutting off the substrate layer. The lettering layer of the lettering film is adhered to an article and then the substrate layer and the middle layer are peeled off, whereby the lettering layer is adhered to the article and the cut characters and/or figures are adhered to the surface of the article.
