Abstract
The utility model discloses a chemical fiber filament spinneret plate which comprises a circular spinneret plate body, wherein spinneret holes which are concentrically arranged are formed in the spinneret plate body, and the spinneret holes are sequentially a hyperbolic diversion channel, a spherical expansion channel and spinneret ports from top to bottom. The chemical fiber filament spinneret plate is additionally provided with the spherical expansion channel between the hyperbolic diversion channel and the spinneret ports, the spherical expansion channel aims at releasing elastic stress gathered in the hyperbolic diversion channel when melt flows through the hyperbolic diversion channel and normal stress generated by the melt flowing, so that surface puffed tension instantly generated after the melt is ejected from the spinneret ports with different section shapes can be reduced, therefore, the pressure drops of the melt during flowing through the spinneret ports with different sections are same. The produced chemical fiber filament is stable in section forming, and the quality of the chemical fiber filament is better.
Description
Technical field
The utility model relates to chemical-fibres filaments technical field, especially relates to a kind of chemical-fibres filaments spinnerets.
Background technology
Along with the development of synthetic fiber industry, structure to fiber product and performance have had higher requirement, and the performance of fiber product is not only relevant with the kind of fiber-forming polymer, and be subject to a great extent the impact of fiber geometries, as fiber number, cross sectional shape, amount of crimp etc., wherein fibre section shape has many-sided impact to the performance of fiber and fabric thereof.
People find in production practices, there are silky luster and style in common triangular-section, the common triangular-section of equilateral triangle section ratio good luster, bulkiness are large, there is the gloss of diamond-like star cross section, irregular cycle sectional tool silk gum style, sawtooth circular cross-section has anti-flash effect, and crescent section can improve water imbibition, " L " tee section hygroscopicity is better, tool gravel style; Porous cross section light weight softness, has extinction effect; " C " shape and ring section light weight, delustring, softness, there are numb sample style, rattan bamboo outward appearance in microscler cross section; Isoceles triangle tee section can improve the elasticity of compression, be difficult for dirty, for the production of carpet; Four square-section, the hole elasticities of compression are high, and heat insulating ability is good, is used as carpet; Hollow shape and abscission ring tee section light weight, tool bulkiness, the elasticity of compression are high, and heat insulating ability is good; Sealene triangle sectional tool leather outward appearance, makes box material; The outward appearance of inhomogeneous hollow shape sectional tool grass, makes floor file straw mattress; The outward appearance of " knife-edge " sectional tool rattan, is used as rattan chair; Flat cross section easily adheres to the marine algas such as laver, in plant, uses; Curved cross sectional profile has careless outward appearance, is used as chinampa; Single hole, porous are mixed tee section and can be improved heat insulating ability, are used as insulation material etc.In addition, profiled fibre is because surface longitudinal is rough and uneven in surface, in aspect function admirables such as hygroscopicity, lightweights.
The effect of spinnerets is by the high polymer molten of viscous state or solution, is transformed into the thread that has particular cross section shape by micropore, through setting medium, is solidified to form strand as air or coagulating bath.Along with the raising of people's living standard, people are also more and more higher to the requirement of various fabric functionals, spinnerets is according to the different performance of fabric, thereby the spinneret orifice of multiple section is combined and produced composite special-shaped fiber, to meet the requirement of people to the multiple performance of fabric.
Composite special-shaped fiber is when spinning, due to spinneret orifice cross sectional shape difference, and melt is in the exit of spinneret orifice, can produce elastic deformation and stress corresponding thereto, in addition, viscoelastic fluid motion will produce normal stress, these anisotropy on melt and the characteristic of extruding fluid all have impact, the moment that melt thread is extruded by spinneret orifice produces a kind of texturized surface tension force, make spinnerets be difficult to guarantee that the Pressure Drop of melt when flowing through the spinneret orifice of different cross section is identical, spinning process is unstable, the chemical-fibres filaments inferior quality of producing, therefore be necessary existing spinnerets to improve.
Summary of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of chemical-fibres filaments spinnerets, and it is rational in infrastructure, can guarantee that the Pressure Drop of melt when flowing through the spinneret orifice of different cross section is identical, spinning process is stable, and the chemical-fibres filaments quality of producing is better.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of chemical-fibres filaments spinnerets, comprises circular spinnerets body, and described spinnerets body is provided with and is the spinneret orifice that concentric shape is arranged, and described spinneret orifice is followed successively by hyperbola flow-guiding channel, spherical expanded passage and spinning nozzle from top to bottom.
Further, described spinneret orifice comprises and is positioned at the circular spinneret orifice of described spinnerets body nexine and is positioned at the outer field trilobal spinneret orifice of described spinnerets body, and the spinning nozzle of described circular spinneret orifice be circle, and the spinning nozzle of described trilobal spinneret orifice is trilobal.
Further, three leaf seams of the spinning nozzle of described trilobal spinneret orifice are isometric, and the length-width ratio of every leaf seam is 3:1.
Adopt after technique scheme, the advantage that compared to the prior art the utility model had is:
Chemical-fibres filaments spinnerets described in the utility model, spinneret orifice is followed successively by hyperbola flow-guiding channel from top to bottom, spherical expanded passage and spinning nozzle, adopt hyperbola flow-guiding channel, can use melt to there is larger shear strain rate, make melt that spiral shell eddy current can not occur when flowing through flow-guiding channel, revolve shape distortion and Crushing Problem, the shape of spinning nozzle has determined that melt flows out the cross sectional shape of cooling rear the formed chemical-fibres filaments of spinneret orifice, compared with the spinneret orifice of existing spinnerets, the utility model has been set up spherical expanded passage between hyperbola flow-guiding channel and spinning nozzle, its role is to discharge that melt gathers when flowing through hyperbola flow-guiding channel that elastic stress therein and melt should flow and the normal stress that produces, the texturized surface tension force that after can making melt by the spinning nozzle ejection of different cross section shape, moment produces reduces, thereby guarantee that the Pressure Drop of melt when flowing through the spinneret orifice of different cross section is identical, the cross section stable molding of the chemical-fibres filaments of producing, chemical-fibres filaments quality is better.
