    摘要: An ultrafine composite fiber of the present invention is obtained by heating and melting a composite-resin-formed product in front of a supply-side electrode and/or in a space between electrodes and extending the composite-resin-formed product by electrospinning, wherein the composite-resin-formed product is a solid-state composite-resin-formed product having two or more phases and including a resin that has a volume specific resistance of 10 15 Ω·cm or less, and that is exposed on 30 % or more of a surface of the composite-resin-formed product. With this, an ultrafine composite synthetic fiber and an ultrafine synthetic fiber can be obtained by electrospinning, without a solvent being mixed in a supply resin, and further, a method for manufacturing an ultrafine composite fiber, as well as a fiber structure containing an ultrafine composite fiber, are provided

    摘要: The invention relates to a method for melting a polymer granulate on a melt element to enable the melted granulates to be spun. In order to allow the granulate to melt in an energetically viable manner, without high thermal or mechanical strain, a melt element which is conically tapered towards the openings on the underside of said melt element is used. The spherical particles thereof are introduced into said openings in the form of a granulate with an average diameter of D3, having a ratio to the entrance-side diameter D1 of the opening of 2 * D3 ≥ D1 ≥ D3.

    摘要: Processes for producing carbon fibre, the filament thereof and pre-oxidized fibre are provided. In one embodiment, the gel spinning of polyacrylonitrile filament is achieved by using small-molecule gelling agent, and the carbon fibre obtained thereby is increased by 15% to 40% in tensile strength and by 20% to 35% in toughness. In another embodiment, the melt spinning process of polyacrylonitrile is conducted by using imidazole type ion liquid as plasticizer, the process reduces environment pollution, is suitable for industrial production and the fibre produced thereby is improved in its strength. In yet another embodiment, polyacrylonitrile pre-oxidized fibre is produced by melt spinning, so low cost and controllable pre-oxidization of polyacrylonitrile can be achieved. In a further embodiment, high strength carbon fibre is manufactured by using polymer thickening agent. In another further embodiment, low cost and controllable pre-oxidization of polyacrylonitrile is achieved by conducting pre-oxidization before spinning, minimizing skin-core structure, so as to produce high performance carbon fibre, and reduce the production cost of carbon fibre greatly.

    摘要: An apparatus and a method for increasing the flow rate of a pressurized liquid through an orifice by applying ultrasonic energy to a portion of the pressurized liquid. The apparatus (100) includes a die housing (102) which defines a chamber (104) adapted to receive a pressurized liquid and a means for applying ultrasonic energy (116) to a portion of the pressurized liquid. The die housing (102) further includes an inlet (110) adapted to supply the chamber with the pressurized liquid, and an exit orifice (112) defined by the walls of a die tip (136). The exit orifice (112) is adapted to receive the pressurized liquid from the chamber (104) and pass the liquid out of the die housing (102). When the means for applying ultrasonic energy (116) is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip (136). The method involves supplying a pressurized liquid to the foregoing apparatus (100), applying ultrasonic energy to the pressurized liquid but not the die tip (136) while the exit orifice (112) receives pressurized liquid from the chamber (104), and passing the pressurized liquid out of the exit orifice (112) in the die tip (136).
