Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2017 / V.29,no.3,Sept Title Development of Retro-reflective Fiber(Ⅰ) - Making of Slit Yarn and Manufacturing of Fabric using in the Warp Threads - Authors Dong-Seok Jeong, Sang-Woon Park1, Il Kweon2 and Tae-Il Chun* Institution/Affiliations Dong-eui University, 1B&B Co., Ltd., 2Kang Dong Textile Pages/Total page pp.139 ~ 147 / 9 Language Korean Abstract Abstract In this study, interesting area of development is retro-reflective thin film and then slitting to form retro-reflective material to be conbined with other fibers to form having retro-reflective characteristics, which slitting yarn can then be to provide fabrics. Glass beads are microscopic spherical size with diameters ranging from several microns to several millimeters. Applying the effects of optical property, glass beads are consumed for road safety used to make traffic signs, safety clothing and others. Glass beads retro-reflective films can be turned into slit yarns through slitting yarn process. The slit yarns can be combined into textiles using diverse methods such as weaving to provide a fabric having retro-reflective characteristics. Lightness and Luminance was increased with decreasing of interval of slit yarn in the fabric. Also, the hue is shifted greenish and bluish with interval of slit yarn.
