Description
Technical field
The present invention a kind ofly can produce two kinds of spinning fibres simultaneously and reduce the melt-spinning apparatus shower nozzle place thermal field melt charging spray silk system to spinning component influences, and this system makes melt spinning product more diversified, and production process is safer, belongs to spinning instrument field.
Background technology
Intensity, function and needs attractive in appearance are reached in order to make textile product, blended yarns is needed under most cases, but simple raw material mixing may make to have an effect between raw material sometimes, the fiber of different materials character can not be had simultaneously, and the yarn formed by multiple fiber combinations can show the character of often kind of fiber simultaneously, there is very strong flexible and changeable property.
The mode of heating of melt electrostatic spinning has multiple, such as electrical heating, LASER HEATING, liquid or gas-heated etc., and wherein Electric heating is low because of its cost, is easy to get, good control and control accuracy higher and adopted by a lot of researcher.Usually, for the point-board-like melt electrostatic spinning of Electric heating, spinning nozzle element is connected with barrel, and one end of electrode is connected on the spinning nozzle that directly contacts with high temperature (being greater than material fusing point) material.When melt electrostatic spinning starts, spinning nozzle element, attachment screw, electrode wires are subject to the heat effects of material transmission and are in high temperature thermal field, have impact on shower nozzle pore size; When spinning stops, various piece gets back to normal temperature again gradually.Temperature repeatedly alternating action easily makes its stripped thread lose efficacy in attachment screw, and electrode wires insulating barrier is also easily aging, brings safety problem.
In order to obtain by multiple fibrous yarn by the method for electrostatic spinning, reduce melt-spinning apparatus shower nozzle place thermal field to the impact of spinning device simultaneously, the invention discloses a kind of spinning feeding spray silk system having double-deck barrel, sectional type shower nozzle, both the product variation of melt electrostatic spinning can have been made, produce two kinds of fibers simultaneously, obtain two kinds of fibrous dichromatism complex yarns or composite fibrofelt, composite cellulosic membrane etc., can get rid of again material thermal field in melt spinning, to the destruction of spinning device, makes spinning process safer.
Summary of the invention
What the object of this invention is to provide a kind ofly can produce two kinds of spinning fibres simultaneously and reduce the melt-spinning apparatus shower nozzle place thermal field melt charging spray silk system to spinning component influences.
A kind of spinning feeding spray silk system having double-deck barrel sectional type shower nozzle of the present invention, it comprises: charging aperture, flow valve, double-deck barrel, temperature controller interface, barrel demarcation strip, material channel, sectional type shower nozzle conduction region, sectional type shower nozzle insulation layer, the electric pole plate of electric field, material distribution plate, incubator; Double-deck barrel every layer arranges charging aperture and temperature controller interface respectively, flow valve is arranged on the junction of material channel and barrel demarcation strip, its control button is arranged on outside barrel through barrel, material distribution plate adopts with sectional type shower nozzle conduction region and is threaded, sectional type shower nozzle conduction region adopts outside small casing to be connected with sectional type shower nozzle insulation layer, is interference fit between the electric pole plate of electric field and sectional type shower nozzle insulation layer.This double-deck barrel is for the accurate adjustment of material before spinning, the material entering double-deck barrel from charging aperture is the fused materials having reached spinning temperature, need material to supplement at any time according to spinning and enter less double-deck barrel, cause the overlong time waiting for spinning always under avoiding a large amount of material to be in spinning temperature, thus occur the phenomenon of degraded or oxidation.The two kinds of fused materials having reached spinning temperature flow into double-deck barrel by corresponding charging aperture respectively, and its temperature and flow are adjusted further by the temperature controller accessed from temperature controller interface and the flow valve for controlling flow respectively; Wherein temperature controller has certain heating function, realizes the constant of melt temperature by electrified regulation, power-off insulation.Double-deck barrel stores similar and different material according to actual needs, and this double-deck barrel also can make multilayer arrangement mode or discrete type, to spin various materials simultaneously.The outside of the airtight annular channel of double-deck barrel, barrel demarcation strip, material channel and material distribution plate, all adopts partiting thermal insulation material, to ensure that material heat is not scattered and disappeared.Two kinds of materials reach material distribution plate through material channel, the spray-head interface on material distribution plate is flowed to respectively through the airtight annular channel one of material distribution plate and airtight annular channel two, the spray-head interface connection segment formula spinning nozzle of material distribution plate, material ejects from corresponding sectional type shower nozzle respectively, obtains two kinds of fibers simultaneously.Be provided with incubator outside the airtight annular channel one of material distribution plate and airtight annular channel two, if the spinning temperature difference of two kinds of materials is large, incubator need be separated and arrange to guarantee that two kinds of materials temperature does not separately reduce.Material is drawn into fiber after sectional type shower nozzle ejects under the effect of electric field force, adopts needle point formula receiver to receive the yarn formed by this two kinds of fiber combinations.
Sectional type shower nozzle is divided into sectional type shower nozzle conduction region and sectional type shower nozzle insulation layer, and sectional type shower nozzle conduction region is on sectional type shower nozzle insulation layer, and two regions adopt outside small casing to connect.The flow of charge transmission that sectional type shower nozzle conduction region is used between material and the external world needs, and this charge property is identical with the polarity of the electric pole plate forming electric field.Sectional type shower nozzle insulation layer has adiabatic feature, and when material flows out from this region, sectional type shower nozzle insulation layer not temperature influence, spinneret orifice footpath size is fixed, and spinning process controls more accurate.In addition, the electric pole plate of material and electric field cuts off by sectional type shower nozzle insulation layer, battery lead plate and electrode wires insulating barrier all no longer temperature influence.Be that interference fit is connected between sectional type shower nozzle insulation layer and the electric pole plate of electric field, connect without the need to metallic screw, equipment safety is higher, and service life extends.This device avoids at spinning nozzle element position the metallic screw using easy temperature influence, by sectional type shower nozzle insulation layer, the impact of heat on spout itself and electrode wires insulating barrier is dropped to minimum, device for spinning is extended service life, thermal loss reduces, control accuracy is accurate, the security improving experiment and produce.
The present invention can produce two kinds of spinning fibres simultaneously, obtains two kinds of fibrous yarns, can reduce again melt-spinning apparatus shower nozzle place thermal field to the impact of spinning device, improves service precision and the life-span of melt-spinning apparatus, ensures to produce and experiment safety.When not heating, the present invention is also applicable to normal temperature solution-polymerized SBR and solution electrostatic spinning.
