DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] As shown in the embodiment in FIG. 1, the twist yarn 800 includes a light guide wire 100, a fluorescent yarn 200, a light-reflecting yarn 300, and a phosphorescent yarn 400. The fluorescent yarn 200, the light-reflecting yarn 300, and the phosphorescent yarn 400 are twisted by using the light guide wire 100 as the central axis. The surrounding surface of the light guide wire 100 is at least partially exposed. Taking a different point of view, the fluorescent yarn 200, the light-reflecting yarn 300, and the phosphorescent yarn 400 surround the light guide wire 100 and cover partially the surrounding surface of the light guide wire 100. The way that the fluorescent yarn 200, the light-reflecting yarn 300, and the phosphorescent yarn 400 are twisted can vary under consideration of usage and manufacture, which is not limited to that shown in FIG. 1.
[0016] The diameter of the light guide wire 100 is between 0.25 mm and 10.00 mm. The light guide wire 100 can be any wire having light guide characteristics. More particularly, the material of the light guide wire 100 includes optical fiber such as glass optical fiber, plastic optical fiber, photonic crystal fiber, etc. Better effect could be obtained by proper design of the ratio of the thickness of the cladding layer to the radius of the core of the optical fiber. The fluorescent yarn 200 can be any yarns having fluorescent characteristics, e.g. yarns that have fluorescent materials mixed in in their manufacturing process or yarns made directly from fluorescent materials. The light-reflecting yarn 300 can be any yarns having light-reflecting characteristics, e.g. yarns that have light-reflecting materials mixed in in their manufacturing process or yarns made directly from light-reflecting materials. The phosphorescent yarn 400 can be any yarns having phosphorescent characteristics, e.g. yarns that have phosphorescent materials mixed in in their manufacturing process or yarns made directly from phosphorescent materials.
[0017] More particularly, external light could enter the twist yarn 800 via the light guide wire 100 and be emitted at least partially to the fluorescent yarn 200, the light-reflecting yarn 300, and the phosphorescent yarn 400. Based on its fluorescent characteristics, with the irradiation of the light emitted from the light guide wire 100, the fluorescent yarn 200 absorbs the light and enters into an excited state and relaxes rapidly into its ground state by emitting light having a longer wavelength. Based on the light-reflecting characteristics, the light-reflecting 300 reflects the irradiation of the light emitted from the light guide wire 100. Based on the phosphorescent characteristics, with the irradiation of the light emitted from the light guide wire 100, the phosphorescent yarn 400 absorbs the light and enters into an excited state and relaxes slowly into its ground state by emitting light having a longer wavelength. The light emitted by the fluorescent yarn 200, i.e. the fluorescence, disappears rapidly when the irradiation on the fluorescent yarn 200 stops. The light emitted by the phosphorescent yarn 400, i.e. the phosphorescence, disappears slowly when the irradiation on the phosphorescent yarn 400 stops. The light-reflecting yarn 300 reflects the irradiation as long as there is light. The light guide wire 100 emits at least partially the external light entered into it. In other words, based on their individual characteristics, when the twist yarn 800 of the present invention receives external light, the light guide wire 100, the fluorescent yarn 200, the light-reflecting yarn 300, and the phosphorescent yarn 400 produce different optical effects simultaneously or separately, hence such arrangement has better aesthetic appeal. On the other hand, since different optical effects are produced simultaneously or separately, it is agile and dynamic. The inventor further calls the twist yarn 800 of the present invention an "agile yarn".
[0018] More particularly, the fluorescent yarn 200, the light-reflecting yarn 300, and the phosphorescent yarn 400 are mixed or overlapped with each other at a specific ratio to obtain a preferred effect. A preferred effect could be obtained by proper design of the proportion of the exposed surrounding surface of the light guide wire 100.
[0019] As shown in the embodiment in FIGs. 2 and 3, the textile structure 1000 includes a textile 900 and a twist yarn 800, wherein the twist yarn 800 is embedded in the textile 900. More particularly, in one embodiment, the textile 900 is interlaced with nylon thread to improve abrasion resistance. The twist yarn 800 is embedded in the textile 900 by weaving. The twist yarn 800 can pass through the rings of the textile 900 along the lateral threads to make the twist yarn 800 interlaced in the textile 900, but the present invention is not limited thereto. The twist yarn 800 can pass through the rings of the textile 900 along the lateral threads, the longitudinal threads, or a predetermined path in accordance with the practical application to make the twist yarn 800 interlaced in the textile 900. Furthermore, the twist yarn 800 can be embedded in the textile 900 by an inlay method, of which the advantage includes the feasibility of obtaining a certain thickness without weaving a thick thickness and the feasibility of combining different materials. The textile structure 1000 has better aesthetic appeal due to the visual effect produced by the twist yarn 800.
[0020] Although the preferred embodiments of the present invention have been described herein, the above description is merely illustrative. Further modification of the invention herein disclosed will occur to those skilled in the respective arts and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.
