The spinning equipment comprises a spinning case and a cluster device arranged under the spinning case, wherein a filament spraying plate is disposed in the spinning case; a plurality of wire stitching devices are arranged between the filament spraying plate and the cluster; and the filaments sprayed by the filament spraying plate enter each wire stitching device and are then clustered to the cluster device. A pre-filament dividing step is also included between the filament spraying step and the clustering step. In the pre-filament dividing step, after filament spraying, the long filament is divided into a plurality of equal sections; and each section long filament enters the wire stitching device for stitching and is then clustered. The beneficial effects of the spinning equipment and method are that filaments are pre-separated, then clustered and separated, so fine denier filaments of different thinness can be achieved; the filament is pre-divided into equal sections, so great evenness is achieved for the filament after the division; high yield and great quality can be achieved; and the spinning equipment and method are suitable for production of filament products with fineness under 15 denier.
Description
Technical field
The present invention relates to technical field of textile machine, be specifically related to a kind of spinning equipment for fine denier filament fiber and spinning process.
Background technology
Fiber refers to the material be made up of continuous or discrete filament, and it comprises the synthetic fiber such as polyamide fibre, terylene, polyvinyl.Polyamide fibre 6 (PA6) technological process of production that current polyamide fibre factory generally takes, polyamide fibre 6 mainly does with PA6 all size and purposes are produced in section long filament through melt spinning, drawing-off, winding.PA6 product basic procedure is: dry section, and---cast hopper------------------------------put in storage the rich shaping of winding head volume up-coiler drawing roller Network device melt metering pump spinning manifold screw extruder intermediate bunker in finished product inspection for filament spinning component, spinnerets by finished product---packaging---.
Wherein section feeds intake and extrusion step: PA6 does section and opens bag and join cast hopper, is then controlled to enter intermediate bunker by pneumatic operated valve, is continuously fed in screw extruder and carries out melting, mixing and metering.Screw extruder has and adds thermal device, and temperature subregion is set up by technological requirement, and screw rod again alternating current generator drives, extrusion pressure when variable frequency control reaches requirement.
Spinning process: melt enters distribution duct under screw rod head pressure, each spinning station is delivered to equably by principle of equidistance, each spinning station is with high-accuracy melt metering pump, melt is after measuring pump accurate measurement, evenly delivered to each filament spinning component, after metal sand and strainer filtering, be emitted into silk from spinnerets.Cooled by the lateral blowing with laminar flow the cross air blowing device optimized from spinnerets molten state strand out.Strand becomes solid-state, and fibre structure generation crystalline orientation becomes large molecule.Strand is forming network, boundling under the compressed air effect of Network device at certain pressure.Oiling device adopts high-accuracy oiling pump fuel feeding, makes strand have the oil content of technological requirement.Spinning manifold and melt pipe all insulation to uniform temperature.
Winding shaping step: the strand that gets off of spinning through vertically entering again between winding, through the commutation of sub-wire roller, sub-wire, then in the drawing roller (HOY is cold roller) heated after drawing-off network, enter high speed winding head automatic rolling doff.
Finished product spinning cake knits socks dyeing through quality testing, enters and be packaged as finished product after classification.
When but extrusion spinning production line general at present produces fine denier filament, because output is very low, thus cause production cost very high; For thinner polyamide fibre fine denier filament, such as 5 dawn, 8 denier filaments, the spinning production line of most China due to allocation problem (such as path etc.) can not do at all or the bar evenness of product very poor.
Summary of the invention
The object of the invention is to make up the deficiencies in the prior art, providing that a kind of continuous yarn product output is high, good evenness is for the spinning equipment of fine denier filament fiber.
In order to reach object of the present invention, technical scheme is as follows:
A kind of spinning equipment for fine denier filament fiber, there is manifold and be located at the buncher below described manifold, spinnerets is provided with in described manifold, it is characterized in that, between spinnerets and buncher, be also provided with some group network devices, through the long filament of spinnerets ejection, after entering each group network device respectively, then be bundled on described buncher.
Preferably, there are in each group network device at least two Network devices setting up and down.
Preferably, also comprise devillicate machine, described devillicate machine is provided with at least two female Si Si volumes.
According to the above-described spinning process for fine denier filament fiber, comprise spray silk, gathering step, it is characterized in that, pre-sub-wire step is also comprised between spray silk and gathering step, described pre-sub-wire step is: after spray silk, long filament is divided into some deciles, and the long filament of each decile respectively by after a group network device screening, then carries out boundling.
Preferably, also comprise sub-wire step, it is characterized in that, in described sub-wire step, same devillicate machine can carry out the sub-wire of different proportion simultaneously.
The beneficial effect that the present invention has:
After pre-sub-wire again boundling, carry out sub-wire again, can produce the very thin fine denier filament of any needs, and pre-sub-wire is also decile, the long filament good evenness therefore after last sub-wire, output is high and quality good.Be particularly useful for the production of the continuous yarn product of fiber number below 15 dawn.
Not only can make one-to-two, the female silk of a point three, points four produces, female silk that also can make one point of five, one points of six, one points of eight equal proportion is produced; And produce the chinlon filament product of two or more specification simultaneously.The spinning not being only applicable to polyamide fibre FDY (full-drawn yarn) is produced, and is equally also applicable to the spinning production of chinlon POY (pre-oriented yarn), HOY (high oriented yarn).
The deficiency of existing production part fine denier filament on spinning equipment can be avoided, thus ensure product quality; The fine-denier polyamide fiber continuous yarn product of needs can also be obtained when not reducing production cost.Such as the price of polyamide fibre PA65D/5f FDY product is 120 yuan/kg in the market; And produce same product by this technology, its production cost is spinning cost 45 yuan/kg+ sub-wire cost 25 yuan/kg=70 unit/kg.
Accompanying drawing explanation
Fig. 1 is the structural representation of spinning production equipment method of the present invention.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, but protection scope of the present invention is not only confined to embodiment.
Shown in composition graphs 1, a kind of spinning equipment for fine denier filament fiber, comprises hopper 1, screw extruder 2, manifold 3, and hopper 1 is located at above the charging aperture of screw extruder 2, and manifold 3 is positioned at the below of screw extruder 2 discharging opening.Be provided with measuring pump and spinnerets 5 in manifold 3, below spinnerets 5, be provided with buncher 6.Between spinnerets 5 and buncher 6, be also provided with some group network devices 4, the group number of Network device 4 is corresponding with the ratio of last sub-wire, such as, be finally one-to-two, be then two group network device 4, a point four, then arrange four group network devices 4, can convert according to actual needs.There are in each group network device at least two Network devices 4 setting up and down, through the long filament that spinnerets 5 sprays, enter each group network device 4 respectively, and successively through each Network device 4 of each group, then be bundled on described buncher 6.
