PURPOSE: To obtain yarn having controlled molecular orientation, by setting an electric field generator separated from a spinneret, applying an electric field approximately parallel to spun yarn to it. n CONSTITUTION: The electric field generator 2 separated from the spinneret 1 is set right below the spinneret 1, and an electric field approximately parallel to the spun yarn Y is applied to it. The electric field generator 2, for example, consists of a pair of the electrodes 5 and 5' and the insulating material 6 to support them. The chamber 7 consisting of the electrodes 5 and 5', and the insulating material 6 is preferably sealed in a gas (e.g., sulfur hexafluoride, nitrogen, etc.) to prevent corona discharge. The electric field generated may be direct current or alternating current, and the field strength is preferably ≥1KV/cm. The distance between the electrodes is preferably ≤30cm. n COPYRIGHT: (C)1984,JPO&Japio |
