摘　　要：设计并制备了规格为22 dtex/3 f的4种不同截面(一字型、两点型、三点型、皮芯型)导电涤纶纤维,并对纤维截面形状、成品颜色、取向度、拉伸性能、导电性能、热稳定性等进行了测试与比较。结果表明,无论选用何种截面,加入碳纳米管/炭黑导电母粒后纤维均具有优异的导电性能(单位电阻处于10~7Ω/cm);相较于皮芯型导电纤维,选用异形截面(一字型、两点型、三点型)在一定程度上降低了纤维内部的均匀性,增加了纤维在制备过程中的取向难度,导致制备得到的纤维取向度以及拉伸断裂强度略有降低,但4种纤维的热稳定性差异不大;异形截面导电纤维能够得到与皮芯型导电纤维相近的导电性能,但由于异形截面导电纤维中裸露在外的碳纳米管/炭黑导电组分减少,其纤维成品颜色明显浅于皮芯型导电纤维,扩大了该类导电纤维的应用范围。Four kinds of conductive polyester fibers with specifications of 22 dtex/3 f were designed and prepared using different cross sections(one-line,two-point,three-point and sheath-core),and the cross section shape,finished product color,orientation degree,tensile properties,electrical conductivity,and thermal stability of the fibers were tested and compared.The results show that regardless of whether the cross section was selected,the fibers with added conductive carbon nanotube/carbon black conductive masterbatch exhibit excellent conductivity(unit resistance is in the magnitude of 107Ω/cm).Compared to sheath-core shaped conductive fibers,the use of irregular cross sections(one-line,one-point,and three-point)reduces the uniformity inside the fibers to some extent,increases the difficulty of fiber orientation during the preparation process,leading to the slight decrease of fiber orientation and tensile breaking strength,but the thermal stability of the four kinds of fibers has little difference.Irregular cross section conductive fibers can achieve conductivity similar to sheath-core shaped conductive fiber,but due to the reduction of exposed carbon nanotube/carbon black conductive components in fibers with irregular cross sections,the color of the fiber products is significantly lighter than that of the sheath-core shaped fiber product,expanding the application range of these types of conductive fibers.
