Abstract
The present invention, which discloses, is related to textile technology field, production technology is wound more particularly to a kind of polyester filament, it is divided into (1) melting extrusion, (2) melt mixed, (3) it filters, (4) spinneret is filtered in metering (5), (6) cooling forming, (7) boundling oils and (8) wind five steps and carry out, slice uneven heating in extruder is even, cause melt uneven, considerable influence will be brought to spinning operation and product quality, therefore melt need to be mixed, our factory mainly adds pin to be mixed using extruder final stage, simultaneously, melt also generates mixed effect in metering head and spinning manifold, by metering pump measure while to melt certain pressure, melt is set preferably to be squeezed out out of spinneret orifice.
Description
Technical field
The present invention relates to textile technology fields, it is more particularly related to which a kind of polyester filament winds production technology.
Background technology
Conventional fibre is not single from appearance after exploitation experienced simulative fiber, high emulation, the super evolution emulated
Upper imitation, and be even more to be copied in terms of microstructure；A series of new products developed, are referred to as fibre in differentiation, also known as " new
It closes fine ".These " shin-gosens " are produced based on terylene by chemical modification or physical deformation, it has special property
Energy, special sense of touch and impression；Product style and performance, which are natural fiber or synthetic fibers, to be obtained；It is knitted from being aggregated to
It makes the processes such as dyeing and finishing and all uses new technology.
Invention content
Problem to be solved by this invention is to provide a kind of polyester filament winding production technology.
To solve the above-mentioned problems, the technical solution that the present invention takes is：A kind of polyester filament winding production technology, including
Following steps：
(1) melting extrusion：Slice enters in screw extruder, by the heating element on screw sleeve to slice
It is heated, while being sliced the friction moved forwards along screw channel in screw rod and being extruded, and be squeezed press compression conveying and generate
Certain melt pressure, each area's temperature of screw rod is according to steady setting again from low to high.
(2) melt mixed：Pin is added to be mixed using extruder final stage；
(3) it filters：After melt self compaction machine comes out, it is carried out in three steps filtering；
(4) it measures：Spinning pump is entered from jacket type delivery pipe by the melt of prefiltration, is carried out by metering pump
It measures while to melt certain pressure；
(5) spinneret is filtered：Melt after tentatively filtering and measuring pump-metered enters component under pressure
Interior, further essence filters, mixes up the melt in component, finally the extrusion molding out of spinneret orifice.
(6) cooling forming：Melt solidification forming under the cooling of cross air blasting from after spinneret orifice extrusion, adds slow cooling plate；
(7) boundling oils；
(8) it winds：Tow is after boundling oils, and finally high-speed winding shapes on winding head.
On the basis of said program preferably, each area's temperature gradient of step (1) screw rod be 160,165,170,175,
180。
On the basis of said program preferably, it is dried using drying tower after step (2) filtering.
On the basis of said program preferably, the method to be oiled using oil nozzle in the step (7).
Advantageous effect：Slice uneven heating in extruder is even, causes melt uneven, will be to spinning operation and product matter
Amount brings considerable influence, therefore need to be mixed to melt.Our factory mainly using extruder final stage add pin into
Row mixing, meanwhile, melt also generates mixed effect in metering head and spinning manifold, by metering pump measure while to molten
Body certain pressure makes melt preferably be squeezed out out of spinneret orifice.
Specific implementation mode
Embodiment：
The technique is carried out in five steps, (1) melting extrusion：Slice enters in screw extruder, by being mounted on screw sleeve
On heating element slice is heated, while the friction that is moved forwards along screw channel in screw rod of slice and being extruded, and by
Extruder compression conveying generates certain melt pressure, and each area's temperature of screw rod is according to steady setting again from low to high, temperature gradient
It is 160,165,170,175,180.(2) melt mixed：Pin is added to be mixed using extruder final stage；(3) it filters：It is molten
After body self compaction machine comes out, it is carried out in three steps filtering；(4) it measures：It is entered from jacket type delivery pipe by the melt of prefiltration
Spinning pump by metering pump measure while to melt certain pressure；(5) spinneret is filtered：By tentatively filtering and counting
Melt after amount pump-metered enters in component under pressure, and further essence filters, mixes up the melt in component, most
The extrusion molding out of spinneret orifice afterwards.(6) cooling forming：Melt solidification forming under the cooling of cross air blasting from after spinneret orifice extrusion,
Add slow cooling plate；(7) boundling oils；(8) it winds：Tow is after boundling oils, and finally high-speed winding shapes on winding head.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
