Technical field
The present invention relates to electrostatic spinning, electrostatic spinning and nanofiber spinning mechanical field, particularly relate to the spinning technique that a kind of electrostatic directly spins micron yarn.
Background technology
In recent years along with the development of nanometer technology, electrostatic spinning technique obtains fast development.The nanofiber yardstick that current electrostatic spinning obtains is mostly at submicron-scale (100 ~ 1000nm), and the real nanofiber being less than 100nm is less.Then how the fiber of sub-micron thickness being narrowed down to nanoscale fiber is need the problem of scholar's research.
Electrostatic spinning fiber all has application in fields such as environment, the energy, biomedicine, photoelectricity, but the form of the film mainly directly piled up with fiber of the electrostatic spinning nano fiber of at present research or felt occurs, be the fiber assembly of two one-dimensional disorders, seriously hinder the expansive approach of this material.Usual yarn can be used for tatting, knitting or braiding, but directly can not be used for knitting, tatting and braiding with bulk fibre, says nothing of and adopts nanometer bulk fibre body.The thickness of simultaneously current electrostatic spinning fiber is partially thick, low strength or very low, is almost difficult to the requirement meeting utility cloth, even directly cannot be woven into cloth.Therefore, become bundles of nanofibers is directly spun into the yarn of micron, and then be applied to woven, knitting or braiding, prepare the fabric of various structures and shape, there is provided the filament strength of electrostatic spinning, refinement monofilament to nano-scale and even thickness, being problem demanding prompt solution in Static Spinning nanometer technology, 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. utilize two roudnel device collect and form the micron yarn of orientations, the method prepare yarn evenness and orientation good, but fiber only has electrostatic field drawing-off, and without any mechanical commutation draft, therefore monofilament is at submicron-scale and intensity is low, fiber yarn forming is partially thick, intensity is also low.Li [Chinese patent ZL201110205027.0] discloses a kind of method and apparatus of electro-spun nanofiber yarn, utilize funnel receiving system, the tube bundle of funnel rear end is tangentially vacuumized, form air-flow and carry out device, but not only cannot realize continuous resultant yarn without drawing-off but also without twisting winding device below.Li [Li N, Materials Letters, 2012:245-247] etc. self-control a kind of funnel type gathering-device that high velocity air is housed, air-flow can form multiple fiber assembly and continuous yarn as power carrier, funnel collector is divided into funnel and cylinder two parts, but high velocity air can only realize twisting effect to nanofiber, without yarn continuously trapping system, final fibre bundle is without the twist.
Qin little Hong, Wu Shaohua [Chinese patent ZL201310058070.8] discloses a kind of orientation Static Spinning continuous yarn preparation facilities and method, it utilizes and be oppositely disposed and the rotation connecing both positive and negative polarity shower nozzle and metal circular target realizes the continuous seepage that nanofiber spins, though the degree of orientation and output height, but also do not exist tow drawing-off, monofilament is partially thick, and intensity cannot be improved, resultant yarn fineness attenuates restricted, and intensity is poor.Usman Ali [Usman Ali, The TextileInstitute, 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. correlative study is also had, do not relate to shearing drawing-off, and horn mouth is only and collects outer side spray and spin the sub-micron fibers that obtains and rotate the mechanism that twisting directly returns the resultant yarn that reels.Principle and the present invention are completely different.Qin little Hong, Wu Shaohua [Chinese patent ZL201320083418.4] discloses a kind of vortex spinning and becomes yarn feeding device, tubaeform conveyance conduit is utilized just to be connected with vortex tube sprocket hole to spinning head, eddy current effect is utilized to twist resultant yarn, though can continuous production nano wire yarn production efficiency higher, but still without shearing drawing-off, then fiber-wall-element model and intensity deficiency.
Li [Li Jie, Polymer Engineering & Science, 2013,54,1618-1624] discloses a kind of polyamide 6,66 copolymer filament yarn continuously static spinning methods.Fibre bundle combines in surfactant body lotion, and the fiber of boundling through being wound into just spinning, then obtains filament yarn through heating and secondary drawing-off, and in order to the drawing-off not easy fracture that reels need control fluid collection device body lotion, the scope of application limits to some extent.Eugene Smit [EugeneSmit, Polymer, 2005 (46): 2419-2423], Yu Hao [Chinese patent ZL201908162] also have similar research work.Its in Static Spinning process without drafting system, both non-straight spun yarns, and in spun yarn, fibre fineness is thick, intensity is low and damage is large, operation is many, energy consumption is large, is undisputable fact.
