Produce the device and method of hollowfil yarns.
Background technique
Method of electrostatic spinning is a kind of special fiber fabrication process, and polymer solution carries out jet spinning in strong electrical field.
Under electric field action, the drop at syringe needle can be become conical (i.e. " taylor cone ") from spherical shape, and be extended from conical tip at thin
Silk, after filament runs a distance in air, is finally solidified into fiber in cathode.This mode can produce nanometer to micro-
The polymer filaments of meter level diameter.Electrostatic spinning is simple with its manufacturing device, cost of spinning is cheap, it is various to spin substance classes,
The advantages that technique is controllable becomes and prepares one of main path of nano-fiber material.It is hollow that hollow Nano fiber in use is that one kind possesses
The function nano material of single-pass configuration, size are distributed between 10nm-10 μm, are indispensable in nanoscale science and technology
Material has huge potential value in thermal insulation material, sewage treatment, filtration membrane research.
Traditional method of electrostatic spinning can obtain non-woven fibrofelt, and fiber architecture is unordered, not can be carried out weaving, thus can only
It applies in comparatively narrow some fields, such as filtering material, tissue scaffold, membrane material and wound dressing etc..By pair
Electric field is constrained, or improves reception device (such as roller reception), it is also possible to obtain the fiber of certain orientation.However, by
It is too low in single fiber intensity, process operation can not be carried out, it is difficult to batch machining production, only with the continuity of some strength
Nanofiber tow uniaxially is produced, and nanofiber can really obtain practical application.Above method efficiency
Lower (consumption spinning solution is 1-3mL/h), it is difficult to obtain volume production fiber；Meanwhile it can only be by secondary for orientation fiber
Twister is just able to achieve the preparation of yarn, greatly limits the application of electrospun fibers.Therefore, it is necessary to the prior art
It is transformed, invents a kind of device based on electrostatic spinning technique one-step method volume production hollowfil yarns.
A kind of electro-spun nanofiber yarn system disclosed in document 1 " application No. is 200810018267.8 Chinese patents "
The preparation method of system and nano-fibre yams, which, which carries out twisting to nanofiber using twist roller, becomes yarn, yarn
With certain intensity, but the system carries out Electrospun using a spinning head, and spinning efficiency is low, and fiber generates in the unit time
Low output, it is to be improved in terms of spinning efficiency.
