Disclosed is a reflective yarn and method of producing it. The reflective yarn comprises 5 to 25 wt % of metalized spherical glass beads, or if necessary, further comprising non-metalized glass beads and/or pearl beads. The spherical glass bead has a bead size of 10 to 50 mum and is vacuum-metalized with materials having reflective function such that ¼ to ½ of surface areas of glass beads are metalized. A method of producing the reflective yarn comprising the steps of vacuum-metalizing materials having reflective function on surfaces of spherical glass beads; melt-spinning the resulting glass beads with synthetic resin having fiber formative function, or melt-spinning the resulting glass beads and the synthetic resin in conjunction with non-metalized glass beads and/or pearl beads to produce monofilaments or hollow fibers; and doubling monofilaments or hollow fibers to produce the reflective yarn. Therefore, the reflective yarn is advantageous in that it realizes an omnidirectional reflection, has a good texture, an improved workability, and an excellent color fastness to washing, physical properties of the reflective yarn are not changed after washing, it can be applied to various applications and can be produced in commercial quantity, and it has a low price.
