PROBLEM TO BE SOLVED: To provide a polyamide monofilament having excellent durability.SOLUTION: A core-sheath composite polyamide monofilament is obtained by combining nylon 11 and a polyether block polyamide copolymer whose polyamide component is nylon 11. In the monofilament, its cross section is a core-sheath composite cross section. In the core-sheath composite cross section, the nylon 11 forms a core part and the polyether block polyamide copolymer forms a sheath part, or the nylon 11 forms a sheath part and the polyether block polyamide copolymer forms a core part. The polyether block polyamide copolymer is contained in the monofilament at a concentration of at least 30 mass%. |
