Abstract:

Objective A fiber dynamic pattern fabric design based on the grating animation principle is proposed to achieve the high-precision dynamic luminous picture pattern on the fabrics with color and brightness control.

Method This paper is based on the principle that grating gives static patterns dynamics. After dividing continuous movements into several specific patterns, a complete pattern is obtained after segmentation and rearrangement. The dynamic luminous fabric pattern was prepared on a jacquard loom by using polymer fiber with diameter of 0.25 mm and cotton yarn as raw materials. The polymer fiber is coupled to the light-emitting diode, and the light-emitting sequence and time of different action patterns are controlled by grouping electronic components grating to show dynamic moving patterns on the flat fabric.

Results Based on the analysis of the principle of raster animation, this paper expounds the realization principle of grating animation and the influence of different parameters on the animation display effect of optical fiber luminous fabric and the realization method for engineering of dynamic picture fabric using optical fiber for practical application. Drawing on the principle of grating animation, the light-emitting diode was adopted to control the optical fiber grouping, so that the animated pattern could be freely transformed on the optical fiber fabric. When the polymer fiber with a diameter of 0.25 mm was used as the smallest luminous unit, the fiber luminous fabric synthesized by 5 frames was found to be the best in the recognition and fluency of animation presentation. When the spacing stripe width was 0.25 mm, the object outline was clearer when the dynamic effect was presented. When the animation was composed of m images, the animation luminous frequency of 1/m s is the most appropriate. In other words, the optical fiber luminous fabric with an interval stripe width of 0.25 mm, a luminous frequency of 1/5 s and a pattern of 5 frames presented the best dynamic effect.

Conclusion Optical fiber luminescence is a dopted to display dynamic patterns, and the original grating image selection mechanism based on grating animation is evolved into an automatic image selection mechanism, facilitated by the use of optical fiber sequential luminescence without the need for a separate layer of grating. The single layer fabric prepared by using optical fiber and ordinary yarn has been proved to display dynamic patterns, which does not require the combination of grating fabric and base fabric as proposed in previous similar studies. By optimizing the fineness of the fiber, a graphic unit with higher precision is formed, and the visual effect of the luminous pattern can be further refined. By giving light to the packet fiber, not only can the white luminous dynamic pattern be obtained, it can also achieve color luminous dynamic pattern and color matching luminous dynamic pattern. The design of optical fiber luminous fabric pattern according to the pattern characteristics presents a new idea for aesthetic innovation of the clothing and textile industry, and also provides a new method for the information exchange in the field of safety warning.
