胆商摘要：The prent invention relates to an ultra-low shrinkage polyester industrial yarn and a preparation method thereof. The ultra-low shrinkage polyester industrial yarn is prepared by spinning a polyester after subjecting the polyester to dissolution, washing and solid-pha tackifying. The ultra-low shrinkage polyester industrial yarn has a dry heat shrinkage rate of 1.8 ± 0.25% under test conditions of 177°C, 10 min, and 0.05
cN/dtex. A mixture of an ethylene glycol magnesium and an ethylene glycol antimony is ud as a polycondensation catalyst. The mixture has a very small thermal degradation coefficient. The invention reduces oligomers during polymerization, reduces thermal degradation during processing, greatly reduces impurities in the polyester, and lowers nucleating agent content in the polyester, leading to a reduction in heterogeneous nucleation and a corresponding increa in the probability of homogeneous nucleation. The dissolution and washing further decreas oligomer content, facilitating grain growth and optimizing crystalline perfection in the ultra-low shrinkage polyester indu
strial yarn fiber. The ultra-low shrinkage polyester industrial yarn has characteristics of relatively low dry heat shrinkage and improved dimensional stability, and can therefore be widely
ud in fabric filters, coated fabrics, hos, conveyor belt wefts, and the like.
