| description | The present invention relates to a high-strength and low-elongation polyester industrial yarn and a preparation method therefor. Modified polyester is subjected to solid-state polycondensation, spinning, winding, and complexing treatment to prepare a high-strength and low-elongation polyester industrial yarn. A method for complexing treatment is: soaking wound fibers in a complexing agent aqueous solution having a concentration of 0.1-0.2 mol/L; the condition for complexing treatment is that if complexing treatment is to be performed at 80-100ºC for 48-72 hours, the concentration of the complexing agent aqueous solution is 0.1-0.2 mol/L; a polyester chain segment of the prepared high-strength, low-elongation, and thermal stable polyester industrial yarn comprises a terephthalic acid chain segment, an ethylene glycol chain segment, and a 2,5-pyridinedicarboxylic acid chain segment, and 2,5-pyridinedicarboxylic acid chain segments of different polyester chain segments are complexed by means of Fe3+; the molar r |
