Abstract

This study prepared 5 retroreflective fabrics of glass beads and colors of silver, gold and purple in order to characterize morphologies, luminance and illuminance properties. Retroreflective fabrics were prepared according to division and area by Samp.1 (Division 2, area $80cm^2$), Samp.2 (Division 2, area $60cm^2$), Samp.3(Division 3, area $60cm^2$), Samp.4 (Division 5, area $50cm^2$), and Samp.5 (Division 1, area $100cm^2$). The results of the morphologies indicate that the back side of retroreflective fabrics was the 3M-Sv, RF-Sv. The RF-Gd of the fabrics were woven fabrics and the SRF-Sv, SRF-Pp was knitting. The largest glass bead size was 3M-Sv and the smallest was SRF-Pp. RF-Sv was the thinnest and SRF-Sv, SRF-Pp were the thickest. The results of luminance properties indicated a tendency to decrease slightly as the number of divisions and area increased, except for Samp.2 to Samp.3. The result of illuminance properties tend to increase as the number of LED becomes greater than the number of divisions in the same area; in addition, the higher the luminance as a whole increases. The results show that it is preferable to use a silver-colored RF-Sv which has the highest luminance and physical properties when a retroreflective fabric is applied to clothes.
