Description

A kind of centrifugal spinning device for the production of composite Nano micrometer fibers
Technical field
The invention belongs to spining technology field, particularly a kind of centrifugal spinning device for the production of composite Nano micrometer fibers.
Background technology
Nanofiber has diameter lower than the fibrous material below hundreds of nanometers.
Fiber can be divided into by cross section structure: one pack system, bi-component and multicomponent fibre; Homofil refers on its cross section it is the fiber be made up of a kind of material or different materials Homogeneous phase mixing; Bi-component and multicomponent fibre belong to the category of composite fibre.Bicomponent fiber refers on its cross section it is the fiber being made up of certain special area structural relation the material of two kinds of different components; Wherein, each component can be the mixing of a kind of material or different materials.According to the structural relation of two components, bicomponent fiber can be divided into: bilateral (also referred to as conjugation) structural fibers, coaxial (same to core) structural fibers, island structure fiber, wrap sharp fiber and merogenesis fiber etc.
Nanofiber has high specific area, transverse and longitudinal ratio.As meticulous by the woven fabric construction of nanofiber, have high porosity, outstanding pliability, adsorptivity, filterability, cohesiveness, heat insulating ability and mechanical strength.The novel performance that these unique characteristics make nanofiber have micrometer fibers not have, is widely used in multiple fields, as high-end textiles, biomedicine, water treatment, the energy, transport, and the various industry such as electronics.In recent years, scientists finds, has the bi-component of special cross-section structure or multicomponent micron/nano fiber and can produce in conjunction with the material of two kinds of different performances brand-new or more excellent than the homofil performance composite nano fiber that many homofils do not possess.Compound micron/nano fiber as multifunctional nano fiber in many important high-end fields, as, protective clothing, biomedical articles (organization bracket structure, artificial human organ, apply hinder material, insoluble drug release etc.), membrane material, filter medium, catalyst, electronic product, the energy are stored, and the fields such as composite reinforcing material have larger application prospect.Wherein, the composite fibre of bilateral (also referred to as conjugation) structure refers to that the material of two kinds of components on its cross section occupies side by side two differences but in adjacent region, each region can have different shapes and size, and two kinds of components are connected to form a fiber at certain position.The composite nano fiber with bilateral structure can be used to produce from curling nanofiber.The composite fibre wrapping sharp structure refers to that the spinning solution of a component on its cross section occupies the main part of fiber, there is tip, the spinning solution of another component is by coated for the tip of the main part of fiber, and the host component of fiber can have the various geometry with tip and size.
At present, traditional textile equipment can produce various bi-component compound micrometer fibers, but cannot produce the composite nano fiber comprising bilateral (conjugation) structure, wrap sharp structure nano fiber.Meanwhile, the device for spinning mainly needle-based method of electrostatic spinning of composite nano fiber of bilateral (conjugation), polygonal structures, bag point structure is produced.In brief, in needle-based electrostatic spinning technique, high voltage source provides a high pressure, and is connected at the metal needle tip of high voltage source anode with the syringe that spinning solution is housed, and is connected by high voltage source negative electrode and ground connection with the gathering-device with electric conductivity.During high voltage source energising, between syringe needle and gathering-device, form high-voltage electrostatic field, the spinning solution in syringe, be injected into the metal needle of energising, under the effect of high-voltage electrostatic field, overcome surface tension, ejection syringe needle, forms charged solid jet, and towards gathering-device accelerating jetting.In this process, jet is elongated rapidly to attenuate, and dry along with the volatilization of solvent, finally on gathering-device, forms solid nano fiber.But needle-based electrostatic spinning technique yields poorly, and requires high voltage, dangerous high, cost is high, simultaneously comparatively large by the performance impact such as solution concentration, viscosity, is difficult to produce in enormous quantities.
