为给导电纤维的生产提供参考,研究PET及不同质量分数导电炭黑/聚酯(CB/PET)导电母粒的熔点、熔融指数、特性黏度等性能,分析导电纤维的复合纺丝工艺,制备了三点外露截面形状的永久性导电纤维,测试了导电纤维的性能.结果表明:随着CB质量分数的增加,CB/PET熔体流动性能变差;在复合纺丝过程中,随着CB/PET导电母粒中CB质量分数的增加,纺丝温度和纺丝压力也要相应提高;导电纤维的导电性能随着CB/PET导电母粒中CB质量分数的增加而提高;随着牵伸比的提高,导电纤维的导电性能下降,导电纤维的最佳牵伸比为1.5.

To provide a reference for conductve fiber manufacturers, the paper investigated the properties such as melting point, melting index and intrinsic viscosity of PET and carbon black/polyester ( CB/ PET) conductive master-batch with different mass fraction, analyzed the compound spinning process of conductive fiber, prepared a permanent conductive fiber with cross-section of three points exposed externally, and tested the properties of this conductive fiber. The results showed that with the CB mass fraction increasing, the melt flowing property of CB/PET conductive master-batch deteriorates. During compound spinning, with the increasing of CB mass fraction in CB/PET conductive master-batch, the spinning temperature and pressure should be increased accordingly. The conductivity of the fiber increased with increasing of CB mass fraction in CB/PET master-batch. The conductivity of the fiber declined with the drawing ratio increasing, and the optimum drawing ratio of conductive fiber is 1.5.
