A coating yarn made of a core yarn made of a polyester resin having a melting point of 130 to 210 DEG C and a coating material containing a thermoplastic resin coated on the outer surface of the core yarn is thermally fused between a core yarn and a coating material in a tenter and a drying process And the difference in shrinkage ratio between the core yarn and the coating material is reduced, so that the punching phenomenon at the cut surface is hardly generated. Therefore, when used as blinds, flooring or other outdoor / interior materials, excellent appearance can be maintained. |
