The Diameter Of Micro-glass Beads To The Performance Of Retro-reflective Fabrics

In this paper, it mainly studies the diameter of micro-glass beads to the influence of retro-reflective fabrics on performance. Firstly, it discusses the performance of single. Secondly, the performance of fabric is studied. It has theoretical analysis, experiment process, and the combination of theory and practice in the study.Firstly, it studies the performance of micro-glass beads mainly on reflection and others in the analysis of single. The result shows that reflection strength of micro bead proportional to square of its diameter. It can't measure the reflection strength of single, for the diameter of micro-glass bead tiny. It chooses glass stick as subject for the same Optical principle to micro-glass bead. In the end the theory is found to be in line with the experimental results.It also firstly studies the performance of fabric mainly on reflection, fastness and others in the analysis of fabric. The results show that micro bead's coverage rate and reflection strength will be higher when the diameter is bigger. After the experiment, it concludes that the number and coverage rate of micro beads as well as thickness, weight on unit area, crocking resistance and reflection strength of fabric will be changed when the diameter to be different.Several factors have been analyzed in detail about reflection function, which is the most essential performance of retro-reflected fabric. The results show that the diameter represents light intensity of single micro beads, the number of which represents glisten dot, the coverage rate represents scotch light. At last it concludes that reflection strength of retro-reflective fabric will rise when all of diameter and coverage rate are bigger.
