Abstract

The invention relates to a polyether-ether-ketone / polyether sulfone composite fiber and a preparation method thereof, and belongs to the technical field of special organic fibers. The composite fiberis mainly prepared from, by mass, 1-99 parts of polyether-ether-ketone and 1-99 parts of polyether sulfone. The polyether-ether-ketone and the polyether sulfone are put into a ball mill mixing machinefor stirring and mixing, and then extruded, cut off and granulated by a screw extruder after drying; the mixed granules are drie, fed into a high-temperature spinning machine for melting and plasticizing, then conveyed by a metering pump into a filter system and a component system, and extruded by a multihole spinneret plate to form polyether-ether-ketone / polyether sulfone fiber melt slivers; filaments obtained after stretching and setting are introduced by a negative-pressure filament suction gun into a winding system and then wound into a filament cylinder, and the finished product is obtained. According to the polyether-ether-ketone / polyether sulfone composite fiber and the preparation method thereof, the technology is simple, the production efficiency is high, the fiber prepared by using the method is good in performance, and various indexes can meet subsequent weaving requirements. The polyether-ether-ketone is blended with the polyether sulfone, the cost of the blend fiber is effectively reduced, and great support is provided for market-oriented popularization of polyaryletherketone fibers.

Description

technical field [0001] The invention belongs to the technical field of special organic fibers, and in particular relates to a polyetheretherketone / polyethersulfone composite fiber. The invention also relates to the preparation method and device of the polyetheretherketone / polyethersulfone composite fiber. Background technique [0002] Polyether ether ketone is a super heat-resistant special engineering plastic successfully developed by the British ICI company in the early 1980s. It is a crystalline polymer material and has attracted widespread attention as a high-performance composite material resin. It has high heat resistance (300°C), good flame retardancy, good radiation resistance, strong chemical corrosion resistance, excellent creep and fatigue resistance, and good electrical properties. [0003] Polyethersulfone is an amorphous thermoplastic high-temperature engineering plastic successfully developed by the British ICI company in 1972. In its structure, the sulfur at...
