Description

Technical Field

[0001] The invention relates to the technical field of clothing, in particular to luminous fabrics, a production process of luminous fabrics and a method for developing the luminous fabrics. Background Art

[0002] Luminous fabric, also known as fiber optic cloth, is a special woven fabric. Plastic optical fiber is added as warp or weft in the weaving. This fabric is mainly used in low-light environments. The outer surface of the optical fiber is covered with a high-reflectivity material as a reflective layer, so that after the light enters from one end of the optical fiber core, it can be emitted from the other end of the core. Before this, the reflective layer has undergone processes such as physical wall breaking method, which can open several areas on the surface of the reflective layer to destroy the total reflection conditions of the reflective layer, so that the light conducted in the core can be more easily transmitted from these areas, that is, after several optical fibers on the fabric are shot into the optical fiber, these areas will show more conspicuous brightness.

[0003] In the process of using this method to display patterns on luminous fabrics by combining several optical fibers, it was found that a grinding roller with a specific surface could be used to break the walls of several optical fibers at the same time, and the starting points when weaving into the fabric could be marked, so that after these optical fibers are woven into the luminous fabric according to the starting point positions, several areas are in a position to form a contour similar to the expected pattern.

[0004] However, since several interweaving points that block the direct connection between the luminous areas appear when the optical fiber and other yarns are woven, when the luminous fabric is viewed at a close distance, the imaging effect of the pattern composed of the bright luminous areas is poor, and the uneven brightness of the luminous pattern can be clearly felt visually because the human eye is more sensitive to the details and continuity within the bright areas.

[0005] In view of the above problems, a luminous fabric, a production process of the luminous fabric and a display method of the luminous fabric are proposed to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the problems in the prior art and to propose a luminous fabric, a production process of the luminous fabric and a method for developing the luminous fabric.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a luminous fabric, including a base layer composed of a plurality of yarns and optical fibers, the yarns and optical fibers staggered in longitude and latitude form a plurality of interweaving points, the surface of the optical fiber is provided with a plurality of wall-breaking areas corresponding to the positions of the interweaving points, an interference layer is fixedly provided on one side of the base layer, the interference layer is made of a light-transmitting material, a plurality of light-expanding grooves are provided on the side of the interference layer facing the base layer, the groove openings of the light-expanding grooves face and are connected to the broken wall area, and a plurality of light rays emitted from the broken wall area position diverge in a direction away from the light-expanding grooves through the light-expanding grooves.

[0008] The present invention is further configured as follows: the cross section of the wall-breaking area is a ring structure, and a reflective layer is provided on the side of the base layer away from the interference layer for total reflection of incident light.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0017] Luminous fabrics, such as Figures 1 to 4As shown, it includes a base layer 2 composed of a plurality of yarns and optical fibers 5. In this embodiment, the optical fibers 5 and the yarns are used as warp yarns and are alternately arranged on the luminous fabric. The organizational structure of the luminous fabric is a plain weave, so the yarns in the weft direction and the optical fibers 5 in the warp direction form a plurality of interlacing points. The warp floating points of the optical fibers 5 and the weft floating points of the yarns are staggered in the same warp direction. A plurality of broken wall areas 51 corresponding to the positions of the interlacing points are arranged on the surface of the optical fibers 5. The plurality of broken wall areas 51 of the plurality of optical fibers 5 form a plurality of highlight areas 21 on the surface of the base layer 2. Since this embodiment only uses one type of yarn to weave the luminous fabric with the optical fibers 5, the spacing between adjacent interlacing points along the warp direction is the same, so the spacing between adjacent broken wall areas 51 on an optical fiber 5 is equal to a multiple of the spacing between adjacent interlacing points along the warp direction, and the specific multiple is related to the shapes of the plurality of highlight areas 21 and the density of the broken wall areas 51 filling the highlight areas 21.

[0018] like Figures 1 to 4 As shown, an interference layer 3 is fixedly bonded to one side of the base layer 2, and the interference layer 3 is made of a light-transmitting polycarbonate material by a calendering method. A plurality of light-expanding grooves 31 are provided on the side of the interference layer 3 facing the base layer 2, and the slots of the light-expanding grooves 31 face and are connected to the wall-breaking area 51. A plurality of light rays emitted from the position of the wall-breaking area 51 are diverged in a direction away from the light-expanding grooves 31 through the light-expanding grooves 31, so that the diverged light rays can cover the weft floating point positions of the adjacent yarns around the warp floating point of each optical fiber 5 in the highlight area 21 under the viewer's perspective, compared with conventional luminous fabrics, thereby effectively improving the uniformity of the imaging of the pattern composed of the bright luminous area when the luminous fabric is viewed at a relatively close distance; Among them, in order to make the light diverge more evenly, the inner wall of the light expansion groove 31 is a semicircular surface and covers the projection of the broken wall area 51, that is, the light emitted from the broken wall area 51 toward the interference layer 3 will be refracted when passing through the light expansion groove 31. At the same time, since the light path of the light is relatively uniform when leaving the broken wall area 51, the light emitted by the light source is relatively stable, so the direction in which the light diverges in the surroundings is also relatively uniform, making the overall brightness of the highlight area 21 more uniform visually.

[0019] like Figures 1 to 4As shown, since there is a gap between the yarn and the optical fiber 5, in order to further improve the uniformity of the light emission of the highlight area 21, the cross-section of the broken wall area 51 is a ring structure, and a reflective layer 4 is provided on the side of the base layer 2 away from the interference layer 3. The reflective layer 4 is a PET aluminum-plated reflective film for total reflection of the incident light. At the same time, in order to make the light shining on the reflective layer 4 pass through the reflection of the reflective layer 4 and more easily irradiate through the gap of the base layer 2, a plurality of halo grooves 41 are provided on the side of the reflective layer 4 facing the base layer 2. The grooves of the halo grooves 41 face and are connected to the broken wall area 51. The inner wall of the halo grooves 41 is a semicircular surface and covers the projection of the broken wall area 51, that is, the light emitted from the broken wall area 51 can be greatly The light is proportionally illuminated in the halo groove 41, and because of the shape of the inner wall of the halo groove 41, it is directed to the surrounding area of ​​the base layer 2 in the broken wall area 51, which covers the gap between the yarn and the optical fiber 5. Also, because the light path is relatively uniform when leaving the broken wall area 51, the light emitted by the light source is relatively stable, so the direction of light reflection in all directions is also relatively uniform. However, because this part of the light needs to pass through the base layer 2, the intensity of this part of the light is softer, which enhances the softness of the light entering the human eye when the highlight area 21 emits light, and improves the visual effect. Furthermore, the surface of the optical fiber 5 without the broken wall area 51 can also be coated with a reflective coating to reduce the obstruction of the optical path by the optical fiber 5.

[0020] The production process of luminous fabrics is used to produce the above-mentioned luminous fabrics, comprising the following steps: S1: Prepare materials, purchase yarns and optical fibers 5, number the optical fibers 5 according to the weaving order, open a number of wall-breaking areas 51 on each optical fiber 5 as needed, place the interference layer 3 made of light-transmitting material in a laminating machine, and mold the interference layer 3 through a first mold set on the laminating machine to form a number of light-expanding grooves 31, place the reflective layer 4 made of reflective material in the laminating machine, and mold the reflective layer 4 through a second mold set on the laminating machine to form a number of halo grooves 41; S2: textile, the yarn and optical fiber 5 are introduced into the shuttle loom as the warp yarn, and with the shuttle loom shuttle driven as the weft yarn shuttle, for weaving the base 2, the surface of the base 2 is formed by a plurality of broken wall areas 51 composed of highlight areas 21; S3: composite, the interference layer 3 and the reflective layer 4 are surface-coated, and then the interference layer 3, the base layer 2 and the reflective layer 4 are composited by a pressing machine to form a cloth body 1; S4: shaping, cooling the cloth body 1 naturally at room temperature, and then cutting the cloth body 1 into a number of luminous fabrics as needed; Among them, the optical fiber 5 in S1 includes a core and a cladding layer coated on the core, the broken wall area 51 is formed by subtractive manufacturing of the cladding layer, and the interference layer 3, the base layer 2 and the reflective layer 4 in S3 can illuminate one end of the optical fiber 5 when aligned, so that the highlight area 21 emits bright light. The luminous fabric in S4 has a section of optical fiber 5 that is not interwoven with the weft yarn at one end. When conducting quality inspection on the luminous fabric, the method of S3 to align the interference layer 3, the base layer 2 and the reflective layer 4 can also be used to inspect the luminous fabric through the luminescence of the highlight area 21.

[0021] Methods for developing luminous fabrics, such as Figure 5 As shown, it includes a controller, an LED lamp, a battery and the above-mentioned luminous fabric. The circuit connects the controller, the LED lamp and the battery. The imaging method is: when the LED lamp is lit, the light emitted by the LED lamp is injected into the interior of several optical fibers 5 in the luminous fabric.
