Description
Technical field
The present invention relates to electrostatic spinning, electrostatic spinning and nanofiber spinning mechanical field, more particularly to a kind of electrostatic
The straight spinning technique for spinning micron yarn.
Background technology
Recently as the development of nanotechnology, electrostatic spinning technique obtains fast development.At present electrostatic spinning is obtained
Nanofiber yardstick mostly at submicron-scale (100～1000nm), and the real nanofiber for being less than 100nm is less.Then
It is the problem that needs scholar's research how the fiber of submicron thickness to be narrowed down to into nanoscale fiber.
Electrostatic spinning fiber has an application in fields such as environment, the energy, biomedicine, photoelectricity, but the electrostatic of research at present
Spinning nano fibre mainly occurs in the form of film that fiber is directly piled up or felt, is the fiber assembly of two one-dimensional disorders, serious resistance
The expansion application of this material is hindered.Generally yarn can be used for tatting, knitting or braiding, but direct is to cannot be used for staple in bulk
Knitting, tatting and braiding, not to mention using nanometer staple in bulk body.The thickness of simultaneously current electrostatic spinning fiber is partially thick, strong
Degree is low or very low, is almost difficult to meet the requirement of utility cloth, or even cannot directly weave into cloth.Therefore, by institute into nanometer
Fibre bundle is directly spun into the yarn of micron, and then is applied to woven, knitting or braiding, prepares the fabric of various structures and shape,
There is provided electrostatic spinning filament strength, refinement monofilament to nano-scale and even thickness, be in Static Spinning nanotechnology urgently
The problem of solution, is also the basis of nanofiber application development.Meanwhile, also there is the report of the straight yarn of some electrostatic spinnings.
As Dalton [Dalton PD, Polymer, 2005,46,611-614] etc. is collected and shape using double roudnel devices
Into the micron yarn of orientations, the method prepares yarn evenness and is orientated, but fiber only has electrostatic field drawing-off, and without any machine
Tool drawing-off, therefore monofilament is in submicron-scale and low intensity, fiber yarn forming thick, intensity partially is also low.Li [Chinese patents
ZL201110205027.0] a kind of method and apparatus of electro-spun nanofiber yarn is disclosed, it is right using funnel reception device
The tangential evacuation of tube bundle of funnel rear end, forming air-flow carries out device, but below not only without drawing-off but also without twisting winding dress
Putting cannot realize continuous resultant yarn.Li [Li N, Materials Letters, 2012：245-247] etc. self-control it is a kind of equipped with a high speed
The funnel type collection device of air-flow, air-flow can form multiple fiber aggregation and continuous yarn, collection funnel as power carrier
Device is divided into two parts of funnel and cylinder, but high velocity air can only realize that twisting is acted on to nanofiber, continuously collect without yarn
Device and final fibre bundle are without the twist.
Qin little Hong, Wu Shaohua [Chinese patent ZL201310058070.8] disclose a kind of orientation Static Spinning continuous yarn system
Standby device and method, it realizes what nanofiber spinned using the rotation for being oppositely disposed and connecing both positive and negative polarity shower nozzle and metal circular target
Continuous production, though the degree of orientation and yield are high, is not also present to tow drawing-off, and monofilament is partially thick, and intensity cannot improve, resultant yarn fineness
Attenuating is restricted, and intensity is poor.Usman Ali [Usman Ali, The Textile Institute, 2012 (1)：80-88]；
He [He J, Journal of Applied Polymer Science, 2014,131 (8)]；He [He J, Polymer
International, 2014,63 (7)：1288-1294] etc. also have correlational study, be not directed to shear drawing-off, and horn mouth is only
Collect outer side spray and spin the mechanism that the sub-micron fibers rotation twisting for obtaining directly returns winding resultant yarn.Principle is with the present invention completely not
Together.Qin little Hong, Wu Shaohua [Chinese patent ZL201320083418.4] disclose a kind of vortex spun yarn device, using tubaeform
Conveyance conduit is connected just to spinning head and with vortex tube sprocket hole, and using eddy current effect resultant yarn is twisted, though continuously preparing nano can be connected
Yarns line production efficiency is higher, but still without shearing drawing-off, then fibre orientation and intensity are not enough.
Li [Li Jie, Polymer Engineering＆Science, 2013,54,1618-1624] discloses a kind of poly-
Amide 6,66 copolymer filament yarn continuously static spinning methods.Fibre bundle is combined in surfactant body lotion, the fiber Jing of boundling
It is wound into and just spins, then filament yarn is obtained through heating and secondary drawing-off, easy fracture need to control liquid collection for drawing-off winding
Device body lotion, the scope of application has been limited.Eugene Smit [Eugene Smit, Polymer, 2005 (46)：2419-
2423], Yu Hao [Chinese patent ZL201908162] also has similar research work.Its in Static Spinning process without drafting system,
Both non-straight spun yarn, and fibre fineness is thick in spun yarn, low intensity and damage that big, operation is more, energy consumption is big, is undisputable fact.
