With the development of society and technology, the demand for flame retardant and antistatic materials gradually increases, therefore, the research of multifunctional nylon materials has aroused general interest in todays nylon material field. Based on research status both at home and abroad and preliminary work of our research group, halogen-based and nitrogen-based flame retardant PA6 fibers were prepared by blend spinning method, and the effect of additives to flame retardant was discussed. In addition, non-covalent functionalized graphene was synthesized as an inorganic conductive filler incorporated into PA6 fibers. And the impact of graphene to the antistatic properties of flame retardant PA6 fiber was explored. The main contents of this dissertation consist of the following points: The development of flame retardant fibers and antistatic fibers were systematically reviewed. The effect of flame retardant methods, flame retardants and antistatic agents to the fiber processing was analysed. The issue was proposed with the discussed status quo and disadvantages of flame retardant and antistatic of fibers. Halogen-based and nitrogen-based flame retardant PA6 fibers were prepared, and the properties effect of anti-dripping agent to
