Polyester film |
| abstract |
PURPOSE:To enable to cause the slidability and surface evenness of a film to be compatible by defining the specified relation between solution haze Hz and turbidity T, while specifying the solution haze Hz and the turbidity T of the solution containing insoluble internal particle in polyester at the manufacture of the polyester. CONSTITUTION:Polyester is manufactured by direct esterification reaction and polycondensation reaction, while feeding continuously the slurry of TPA and ethylene glycol (EG) to the mixture of terephthalic acid (TPA) and BHET, and esterificating them. The polyester is suitably diluted with single polyester or the polyester without containing internal particles, and is extruded into a sheet-shape at molten state. Then it is drawn, heat treated and made into a polyester film with superior evenness and slidability, causing the maximum surface roughness to be 0.3mum or less and dynamic friction index to be 0.75 or less. The polyester containing internal separated particles has solution haze of 13 or more and the molten polymer has the turbidity of 0.8 or more, and in this condition, the polyester in which the solution haze Hz and the molten polymer turbidity T satisfy the relation of a formula. |
