摘要： PROBLEM TO BE SOLVED: To provide a badminton string excellent in ball hitting feeling and durability by preventing the reduction of the breaking strength and elongation degree of polyamide multifilament core strings in a manufacturing process. SOLUTION: The tough polyamide multifilament used as the reinforcing material for vehicle tires is used in a core portion of the badminton string, the polyamide multifilament is coated with a copolymer type thermoplastic resin solution (2-25% by weight) comprising a thermoplastic polyurethane, a polyamide elastomer, a copolymer polyamide, a polyester elastomer, and a copolymer type polyester, the reduction in the property is prevented in the string processing process, further a core string portion and a side string portion is firmly adhered to obtain the string with elasticity which is easily stretched.
