香味聚丙烯纤维的研制

INVESTIGATION IN THE AROMATIC POLYPROPYLENE FIBER

研究了香味聚丙烯纤维的成形，并对添加香料的热性能，香料对聚丙烯流动性能的影响，以及香味聚丙烯纤维的纺丝进行了探讨。结果表明，复合香料加入聚丙烯后热分解速率降低，并增加了聚丙烯熔体的流动性能，在较低纺丝温度下具有较好的可纺性，纤维的力学性能比未加香料的聚丙烯纤维有所降低。

The formation mechanism of the aromatic polypropylene(PP) fiber was studied. Both the thermal property of the aromatizers and the effect of the aromatizers on PP melt flow behavior were discussed. Moreover, the spinning process of aromatic PP fiber was studied. The results showed that the composite aromatizers made PP thermolysis rate decrease and caused MFI increasing. The PP added the aromatizers has good spinnability at lower temperature, but the mechanical property of aromatic PP fiber is lower than that of PP fiber.
