| 摘 要： | 通过对五种不同Sb/Ti配比半光聚酯热性能研究发现,Sb/Ti复配聚酯熔融结晶温度Tmc高于锑和全钛,50/50温度最高,复配聚酯熔体成型性能弱于锑系;复配聚酯冷结晶峰温Tc高于锑系,后加工性能强于锑系。采用UDYDT路线的可纺性研究发现,复配聚酯原丝粘度降高于锑系聚酯,原丝强度高于锑系,DT丝的变化未表现出明显规律,纺丝温度296℃时,复配聚酯DT的强度可以达到与锑相当。

| Abstract: | The thermal performance data of Sb/Ti polyester suggested that Tmc of Sb/Ti compound catalyst polyester were higher than Sb polyester, Tmc of 50/50 was highest. Thermoformability of compound catalyst polyester were weaker than Sb polyester. Tc of compound catalyst polyester were higher than Sb polyester, drawing performance were better than Sb polyester. Through UDY-DT route, oil-free yarn viscosity drop and strength of compound catalyst polyester were higher than Sb polyester, DT hadn`t the regular charge. At 296 ℃, strength of compound catalyst polyester were corresponded to Sb polyester. |
