Study On Development Of Fiber Optics Fabric For Pattern Changeable And Optical Simulation

Fiber optics fabric for pattern changeable has a strong artistic effect, and it can be used for interior decoration sector, stage costumes and other fields. The artistic expression of traditional fabric that used for decoration and stage costume depends on their color, texture, grain, pattern and other factors. A whole new frontier in color design and artistic expression are opened up with the development of modern textile technology and the emergence of new materials, especially the emergence of light emitting fabric. The fiber optics fabric for pattern changeable was made by embedding optical fibers into textile through multiple-weft weave to develop the patterns. The shape and color of patterns can be changed through the design of circuit and control unit. The pattern on the surface of the fabric can be designed as traditional floral pattern or a single piece of plant or animal pattern that makes light emitting fabric with better decorative effect. The light emitting fabric produced by this method can be widely used in stage costume, decorative, security alert, medical and other fields due to the merits of luminous, soft, the shape and color of lighting pattern changeable. It also can be further developed as flexible display, and lay the foundation for the development of wearable computers.The main research works in this paper as follows:1. Analyzed the mechanical prosperities of two kinds of optical fibers. BM-5A luminance colorimeter was used to measure the luminance of the optical fibers after room temperature tensile and heating tensile and the SEM was used to test the surface morphology of the optical fibers. A preliminary experiment analyzed of the impact of the elongation and temperature on the side-glowing luminance of the optical fiber.2. Simulated the woven fabric geometric of optical fiber fabric. The metal rods as warp yarns, and used the Peirce model to characterize the buckling wave height and radius appeared during interlacing, tested the side-glowing luminance of optical fiber, and then analyzed the relationship between the bending form and the side-glowing luminance.3. Optical fiber and polyester yarn was used as weft and warp separately to produce optics fabric with different weaves by the loom. The buckling wave height, radius of optical fiber and the thickness and luminance of fabric were calculated separately, and then analyzed the relationship between the weave and the luminance of fabric.4. The fiber optics fabric was produced in jacquard loom by the application of CAD system in pattern design and weaves design. Used circuit and control unit to make the pattern alternating in the fabric and tested the luminance of the fabric by BM-5A luminance colorimeter.
