PURPOSE:To obtain the subject wiry material excellent in lightweight properties, flexibility, etc., by placing a thermoplastic resin around a combined filament yarn consisting of a reinforcing fiber and thermoplastic resin fiber and heating the resultant fiber at a temperature above the melting point of the above- mentioned thermoplastic resin under tension. CONSTITUTION:A reinforcing fiber, such as glass fiber or carbon fiber, and a thermoplastic fiber, such as polyamide fiber, are used to prepare a combined filament yarn by treatment with an air stream, etc. A thermoplastic resin fiber is then placed around the afore-mentioned combined filament yarn to form a fiber bundle, which is then heated at a temperature above the melting point of the above-mentioned thermoplastic resin to afford the aimed wiry material, having stabilized quality, excellent in impregnation properties and suitable in the field of civil engineering, construction, marine, etc. |
