| titleOfInvention | Polyester sheet and film forming method |
| abstract | (57) [Summary] (Modified) [PROBLEMS] To provide a polyester sheet and a film forming method capable of producing a high-quality sheet or film having excellent surface smoothness at a high speed. SOLUTION: In a sheet forming method in which a molten sheet of polyester containing 2,6-naphthalene dicarboxylic acid as a main acid component is extruded from an orifice-shaped die and is adhered to a cooling roll by an electrostatic adhesion method to be solidified, The initial accumulated charge amount of the melt is 2.2 to 8.0 μC / Mm 2 , the cooling roll is a cooling roll on the surface of the microcrack, and the sheet forming speed is 40 to 2 A method for forming a polyester sheet, characterized by being at a speed of 00 m / min, and a method for forming a polyester film, wherein the formed sheet is biaxially stretched in the machine direction and the transverse direction. |
