Description

Technical Field

[0001] The present invention relates to the technical field of reflective fabric production, and in particular to a microbead dispersing device and process for reflective fabric production. Background Art

[0002] Reflective fabric has high visibility. It can reflect light under light and provide high visibility even in low light or night conditions. Commonly used reflective materials such as glass beads can reflect light back to the light source, making the target object more eye-catching, so it is often used on traffic signs. When the reflective fabric is produced, the glass beads are fixed to the surface of the base fabric by hot melt adhesive, so that the base fabric has reflective properties. According to the density of beads on the surface of the base fabric, it can be divided into flexible reflective fabric and solid reflective fabric. The content of beads on the surface of flexible reflective fabric is lower, so the reflective effect is also lower, while the reflective effect of the surface of solid reflective fabric is very obvious, but the curvature of solid reflective fabric cannot be adjusted, which is not convenient for production.

[0003] In the prior art, when solid reflective cloth is produced, since the solid reflective cloth cannot be bent and adjusted after production, the solid reflective cloth can only be manufactured according to a mold of a certain shape, and the manufacturing cost is relatively high. When the solid reflective cloth with different curved surfaces is coated with microbeads, since the curvature of the surface of the solid reflective cloth cannot be adjusted, the existing microbead spraying mechanism cannot accurately spray the surface of the reflective cloth at an angle of 90 degrees, resulting in different densities of microbeads at different curvatures on the surface of the reflective cloth, and air holes are easily generated, thereby reducing the quality of the reflective cloth.
