PURPOSE: Provided is a recurrent reflection filament, which ensures flexibility of yarn required in lacing, sewing, fabricating and knitting processes and displays elegant and various colors. Also, a recurrent reflection yarn is provided which is manufactured by using the same. CONSTITUTION: A recurrent reflection filament is manufactured by conjugated spinning a mixture of a recurrent reflection material and a first polymer, and a second polymer in a weight ratio of 5-95:95-5. The filament comprises a recurrent reflection material such as glass beads. The first and second polymer materials are at least one selected from a group consisting of nylon, polyester and polypropylene. The filament obtained from spinning process has a core layer made of the second polymer and an outer layer made of the mixture. The filament is added with pigment or reflection efficiency increasing agents.
