In a fastener chain (2) of the invention, at least some of warps (15, 35) constituting a woven fastener tape (10, 30) is provided with a flame retardant phosphorus-copolymerized polyester fiber (17, 37), and wefts (16, 36) constituting the same fastener tape (10, 30) is provided with a synthetic fiber (18, 38) that is not phosphorus-copolymerized and that has a higher degree of tensile strength than the flame retardant polyester fiber (17, 37). With this configuration, superior flame retardancy can be stably obtained and even when producing large quantities of fastener chains (2), there is no variance in the flame retardancy of the fastener chains (2). In the fastener chain (2), the heat contraction of the warp (15, 35) is used to improve the chain horizontal pull force, and by increasing the frictional resistance between the warp (15, 35) and the weft (16, 36), shifting of the weave pattern of the fastener tape (10, 30) can be prevented. Further, the fastener chain (2) can be provided at a low cost because of the small amount of flame retardant polyester fiber (17, 37) used. |
