Abstract: The present invention relates to retro-reflection yarn having a retro-reflection function and a method for manufacturing the same. According to the present invention, the retro-reflection yarn having a retro-reflection function is manufactured. The retro-reflection function is maintained for a long time by preventing retro-reflection materials, which are fine glass beads coated on the yarn, from escaping the yarn. The retro-reflection yarn has good weaving properties as tensile strength is increased. In addition, durability of woven fabric manufactured by using the retro-reflection yarn is excellent. The retro-reflection yarn can be used for various purposes such as sewing yarn. The retro-reflection yarn having a retro-reflection function is manufactured by obtaining a retro-reflection film by coating a film with the fine glass beads, obtaining film yarn having a retro-reflection function by cutting the retro-reflection film, and braiding transparent mono-filament yarn on the outside of the film yarn which is used as core yarn. Accordingly, the core yarn, coated with the materials performing the retro-reflection function, is located inside the braiding yarn. Consequently, the retro-reflection yarn can be protected from friction of the outside, and the tensile strength of the retro-reflection yarn can be increased.
