摘要： Polyester fibers having high tenacity and high modulus can be produced practically and economically by melt-spinning a copolyester at a take-up speed of 3,000 meters/min. or more. The copolyester comprises at least 60 mol % of ethylene terephthalate units, has a persistence length of 15 angstroms or more and does not show a liquid crystalline nature in the molten state.

摘要： A process for producing high tenacity high modulus polyester fibres comprises subjecting a copolyester melt comprising at least 60 mol% ethylene terephthalate units to melt spinning at a take up speed of at least 3000 m/min. The copolyester has a persistence length of at least 15 ANGSTROM (1.5nm) and does not show liquid crystalline properties in the molten state. The spinning of the copolyester melt is designated pseudo-liquid crystal spinning.
