摘　　要：以碳黑为导电介质,以PET为基体,用共混方法纺出共混导电纤维.研究表明,提高碳黑的分散性能提高共混体系的可纺性和导电性;并随着碳黑含量的增加,导电性提高;当碳黑含量达2200时,电阻为105Ω/cm,但可纺性和机械性能变差,此时,只适合于用作复合纤维的导电组分.Using carbon black as conductive medium and polyester as matrix the carbon black/polyester composite fiber was prepared with the blend method.The study results show that, the spinnability and conductivity of the fiber are increase with increasing the disperse of the carbon black in the blend system;the conductivity of group is improved with increasing the content of carbon black in the blend system; when the carbon black content is 22~0_0, the resistance is 10~5 Ω/cm but the spinnability and mechanical behavior are decreased, and at this time the fiber is just used as the conductive part of composite fibres.
