Summary:PURPOSE:To stabilize the melt-spinning process by suppressing the development and accumulation of staining substance around the polymer nozzles on the spinneret which is one of the most process-inhibitory troubles in the spinning process. CONSTITUTION:The melt-spinning process is characterized by using a spinneret which has its polymer extrusion surface or a combination thereof with the inner surfaces of individual nozzles plated 0.5 to 20mum thick with a plating composition containing 1 to 25 pts.wt. of at least one selected from fluorinated graphite particles and polytetrafluoroethylene particles of less than 10mum average particle size per 100 pts.wt. of the metal component to be plated, at least one selected from chromium, nickel and cobalt.
