涤纶导电纤维的制备及性能研究

摘要

采用溶解-涂覆法,将钛酸酯偶联剂处理后的导电炭黑分散在苯酚和四氯乙烷溶液中,与一定量的聚酯树脂或纤维充分搅拌,然后将涂覆液均匀地涂覆在涤纶纤维表面,制备出涤纶导电纤维.测试导电纤维的耐水洗性能和力学性能,研究了涂覆液中炭黑含量对涤纶导电纤维电阻率的影响.结果表明,所得涤纶导电纤维的电阻率可达102 Ω·cm,并且具有较好的导电耐久性.%The conductive polyester fiber has been prepared by the dissolving-coating method on the surface of polyester fiber treated by the titanate coupling agent using the mixture of conductive carbon black,phenol,and tetrachloroethane,respectively.The water resistance and mechanical properties of conductive fiber have been characterized and the effects of the carbon black content in the coating liquid on the resistivity of the polyester conductive fiber have been studied.The results show that the resistivity of polyester conductive fiber reaches 102 Ω · cm and presents good conductive durability.
