The spinning manifold has the advantages that the POY and FDY composite yarn productivity and the POY and FDY composite yarn production efficiency can be guaranteed against being affected, so that the quality of obtained products is high, and the moisture absorption and the breathability of fabrics can be obviously improved.
Description
Technical field
The present invention relates to a kind of manifold, be specifically related to the manifold of a kind of POY of production and FDY composite fibre.
Background technology
Spinning manifold is comprised of melt distributing pipe, measuring pump, filament spinning component, and the melt being filtered enters spinning manifold.The raw vapor recycle of leading that the heating of casing and melt pipe is produced by an electric furnace heats.Spinning manifold has 6 positions, and a measuring pump is joined in each position, and melt quantitative is pressed into assembly, through the pore of spinnerets, is extruded and forms melt thread.The effect of spinning manifold in spinning technique process roughly has the following aspects:
1, the temperature needing is arrived in melt insulation in the pipe arrangement of spinning manifold, and keeps the even of temperature.
2,, under certain spinning speed, rely on the revolution of measuring pump fix and control melt discharge-amount, to obtain the precursor of certain fiber number.
3, the mechanical admixture in melt and agglutination particle are further filtered by the screen pack in assembly and mistake filter sand, and further fully mix in assembly, prevent the difference of temperature-viscosity, simultaneously due to melt under high pressure by screen pack and the mistake filter sand of high-drag, make melt produce high shear rate, improve the mobile performance of melt, make again the instantaneous even raising of melt temperature, thereby guaranteed the homogeneous of ejection melt thread quality.
Interior 6 discharging openings corresponding to filament spinning component of spinning manifold that polyester FDY filament is spun in 12 of existing productions are uniformly distributed, unaffected but existing spinning manifold is difficult to guarantee to produce POY and FDY compound silk production capacity and production efficiency.
Summary of the invention
The object of the invention is, for guaranteeing production capacity and production efficiency unaffected production POY and FDY compound silk, to propose the manifold of a kind of POY of production and FDY composite fibre.
The object of the invention is to realize in the following manner:
A kind of manifold of producing POY and FDY composite fibre, comprise spinning manifold, melt distributing pipe, measuring pump and filament spinning component, filament spinning component for the production of POY silk is double parallel setting with the filament spinning component of producing FDY silk, each filament spinning component for the production of POY silk arranges two blocks of spinneretss for spraying silk, and each filament spinning component for the production of FDY silk arranges two blocks of spinneretss for spraying silk.Filament spinning component for the production of POY silk arranges 6, for the production of the filament spinning component of FDY silk, arranges 6.Produce in the spinning manifold of POY and FDY composite fibre, the feeding manner of filament spinning component is twoport feed, the filament spinning component charging aperture of producing POY silk is two charging apertures, the filament spinning component charging aperture of producing FDY silk is two charging apertures, the fiber number that can use the motors of metering pumps control POY silk of single frequency conversion, the motors of metering pumps of single frequency conversion is controlled the fiber number of FDY silk.Filament spinning component is of a size of: long is 16cm, is widely: 8cm.FDY of the present invention and POY compound silk are X-type profiled filaments, and the FDY of other types and POY compound silk also available this manifold are produced.
Spinnerets in filament spinning component is ellipse or circle, and the silk of every spinnerets ejection is 1 bundle.Every block of spinnerets of producing POY silk is provided with 72F " X " type spinneret orifice; Every block of spinnerets of producing FDY silk is provided with 36F " X " type spinneret orifice.The middle angle of " X " type spinneret orifice is 110 °～130 °, can significantly reduce in melt micropore trapping phenomena while flowing." X " type spinneret orifice lateral blowing is perpendicular to " X " mitre face.The leaf of " X " type spinneret orifice is wide is 0.1～0.15mm, " X " type spinneret orifice leaf long with the wide ratio of leaf be 12～18.Spinneret orifice is from inside to outside concentric structure and arranges.Described spinneret face diameter is 60～80mm, and preferably plate surface diameter is 70mm.
Beneficial effect of the present invention compared with the prior art: it is unaffected that manifold physical efficiency of the present invention guarantees to produce production capacity and the production efficiency of POY and FDY composite fibre, similar to the polyester FDY filament efficiency of production single kind, the product quality obtaining is high, can significantly increase hygroscopicity and the gas permeability of fabric.
Spinnerets spinneret orifice is " X " font, the POY of " X " font section of producing thus and the effect that FDY " X " type composite fibre has good moisture absorption, perspire, and due to the fabric micropore quantity more " X " being made into it, therefore permeability is better, can approach the performance of cotton fiber.
