PURPOSE: To aim at solution for a problem on a drop in filature properties at the initial stage of operation and removal of surface smudges at the discharge side as well as improvements in operatability for silicon coating, by spraying a specified abrasive grain mixed liquid to the discharge side surface of a melt spinneret, while constituting a peripheral part at the discharge side so as to be polished for the specified chamfering.
CONSTITUTION: A processed spinneret 8 is placed in a rack 7 installed in an intermediate position of a processor body 1, while a liquid 2 being made up of mixing compressed air 9 and abrasive grain of metal or the like of 700W1,500 mesh so as to cause the weight ratio of liquid to abrasive grain to become about 20:1W10:4 in ratio is sprayed 4 to the spinneret 8. And, a peripheral part at the discharge side is finished into a chamfering state polishing value of about 2W6μ. With this constitution, solution for a problem on a drop in filature properties at the initial stage of operation, prevention against surface smudges at the discharge side and improvements in operatability for silicone coating are all well promoted.
