PURPOSE:To obtain good wire appearance and excellent wire feedability by sticking specific amts. of a fluoroplastic, metal soap and fats and oils to the wire surface. CONSTITUTION:The fluoroplastic of 0.01-1g for each 1m<2> of wire surface, 0.02-2g metal soap and the fats and oils are stuck to the wire surface. For example, a polytetrafluoroethylene resin is utilized for the fluoroplastic. The fluoroplastic is suspended in a freon solvent such as trichlorofluoroethane and film formation is executed by passing the wire into such liquid suspension in the case of a film treatment. The metal soap is drawn into a die by the effect of the fluoroplastic which is the pretreating agent and after the metal soap exhibits excellent drawability, the metal soap sticks uniformly to the wire surface, thus assuring the excellent feedability. |
