Description
Technical field
The invention belongs to polylactic acid melt or polylactic acid high polymer particle spining technology field are and in particular to a kind of polylactic acid
Fibre high-speed spinning process.
Background technology
The technical information of acid fiber by polylactic spinning can be seen in disclosed Chinese patent literature, such as CN104294384A
（Acid fiber by polylactic hypervelocity spinning technique）、CN104562252A（Acid fiber by polylactic adjustment spinning, false twisting integral system）、
CN105369417A（Acid fiber by polylactic composite spinning technology and device）、CN105803565A（Polylactic acid delustering fibre Direct Spinning
Silk production technology）And CN105714391A（Polylactic acid bi-component composite fiber spinning technique）, etc..
By to being not limited to the reading of above-mentioned patent documentation that enumerates and combine the spining technology commonly using at present
Understand acid fiber by polylactic spinning technique flow process be：By drying tower, polylactic acid high polymer particle is introduced screw extruder melting to squeeze
Go out, after filtering through fondant filter, introduce dosing pump through melt pipe again, introduce manifold spinning after being measured by dosing pump, by spinning
Spinneret orifice on the spinneret of filament spinning component of silk case sprays, and the tow being sprayed by spinneret orifice is successively through ring wind quenching device ring
Quenching and oiling device oil after by drafting system draw roll drawing-off, wire feeder is imported by guide roller, is filled by wire feed
Put to send and introduce after cutter cut-out and contain silk cylinder（Also can claim to contain silk cylinder）.
Due in current acid fiber by polylactic spinning polylactic acid melt in spinning equipment as residence time is relatively in manifold
Long（The low reason of spinning speed）, thus easily there is high temperature degradation in spinning process, add that polylactic acid melt viscosity is higher,
Significantly expanded phenomenon can be formed in the plate face of spinneret when melt is extruded from the spinneret orifice of spinneret, and polylactic acid melt
In be entrained with oligomer, easily stick in the plate face of spinneret so that spun acid fiber by polylactic be in having many bends or curves and table
The rough phenomenon in face.Then during producing non-woven fabrics using polylactic acid short-fiber, because fiber surface is random curved
Bent and rough, it is also easy to produce electrostatic, serious curling round the roll, the spun lacing in Shi Hou road or acupuncture can occur during lapping machine lapping
Cannot be smoothed out.Show through the test that the applicant is done, if being significantly improved the spinning speed of acid fiber by polylactic, that
Aforesaid expanded phenomenon can eliminate, because with the raising of spinning speed, the drawing point of melt can be from the spray webbing of spinneret
Move at hole, move to capillary in the hole at expanded of the melt from die orifice exit, move on spinning fibre drawing point the most at last
The spray webbing in the hole of spinneret.Through further tests showed that the applicant is done：The percentage elongation of spun fiber can reduce
To critical field, the degree of crystallinity of fiber and orientation improve rapidly, and strength increases, and boiling water shrinkage declines, all technical
All reach the requirement of finished silk；When spinning speed reaches 7000-8000m/min, the items of spun acid fiber by polylactic refer to
Mark can reach desired optimum state.In addition, using after high speed spinning, because the melt time of staying in a device significantly contracts
Short, thus high temperature degradation degree substantially mitigates, fiber quality is obviously improved.
But, due to ring wind quenching device used in the ring blowing operation by current polylactic acid spinning, oil operation
In in oiling device used and wire feed operation the multiple restriction of wire feeder used and be objectively difficult in addition basic no
Method realizes the spinning speed of aforementioned 6000-8000m/min.
For ring wind quenching, in order to adapt to the rate of cooling to fiber in acid fiber by polylactic high speed spinning, existing skill
The measure that art is taken is：On the one hand reduce the temperature of the cold wind coming from air-conditioning device, on the other hand increase in the unit interval
The air quantity of cold wind and wind speed.But facts have proved that this measure is worthless, because ought exceedingly reduce that air-conditioning dress is come from
During the temperature of the cold wind put, the spinneret of the structural system of filament spinning component can be caused be quenched, thus because quenching causes fiber sheath
Core difference increases, and strand hardens, and feel is deteriorated, the quality of impact fiber；Again because blindly increasing the cold wind in the unit interval
Air quantity and wind speed, both can cause dissipating of tow, the increase of energy consumption can have been caused again.
The technical information of the ring wind quenching device of melt spinning can be seen in disclosed Chinese patent literature, such as

" a kind of multistage ring hair-dryer of hollow polyphony thioether short fiber ", the common feature of this two patent formula is adjusted to cooling wind
Section, such as the former carries out Staged Air Injection, so that the wind speed of cooling wind in passage for the entrance tow is tapered into from top to bottom（Explanation
The 0020th section of book）；As the latter is adjusted to blast（Description 0009-0010 section）.But be not all given and pathogenic wind-warm is implemented
The enlightenment that gradient is adjusted is not that is to say, that provide the enlightenment that tow is implemented with gradient ring wind quenching.But through the applicant institute
The test done shows, gradient cools down the drawbacks of can eliminate measures first mentioned, meets the requirement of high speed spinning.
For oiling, the oiling device of the acid fiber by polylactic spinning in prior art as shown in Figure 10, including food tray

When low, liquid-level switch is passed through by ball-cock assembly（Sensor）Give control device to signal, operation of oil pump is ordered about by control device, with
10 repairings into fuel tank.
From above-mentioned Figure 10, the liquid level of the oil preparation in food tray 4 is identical with the liquid level of fuel tank 10, no matter the oil of i.e. food tray 4
Oil level height in disk chamber 42 each depends on the oil level of fuel tank 10, and food tray 4 itself does not have the work(that the liquid level to oil preparation is adjusted
Can, the oil preparation no circulation ability particularly in food tray chamber 42, it is also easy to produce the rotten situation of change because oil preparation does not flow, affect polylactic acid
The quality of fiber（Go mouldy and lead to）.
Figure 11 show the oiling device of the acid fiber by polylactic spinning with oil preparation circulatory function in prior art, bag
Oil scraper disk 4；For providing the food tray fuel feed pump 5 of oil preparation, one end of this food tray fuel feed pump 5 and food tray base plate into described food tray 4
41 connect and the fuel feed pump oil-out 51 of one end of this food tray fuel feed pump 5 is communicated with the food tray chamber 42 of food tray 4, and food tray fuel feeding

All there is no the liquid of the oil preparation that the oil preparation of food tray intracavity not only can have been made voluntarily to circulate but also can make food tray intracavity in the aforementioned patent enumerating
The dual-use function that position is adjusted according to need.
For wire feed, the structure of the wire feeder commonly using in prior art is as shown in Figure 12, transversal including a pair
Face shape is in quincuncial godet 40, is drawn, by a pair of godet 40, the tow 60 being introduced by guide roller 50 in the way of drawing
To the fiber barrel of lower section.The surface-coated of a pair of godet 40 of the wire feeder of this structure has aluminium sesquioxide film layer,
Through expanding with heat and contract with cold, this film layer easily comes off and causes roll surface coarse, easily undermines tow 60.Especially, due to employing a pair of seal wire
Roller 40, thus the tow drawn can be in the curly of spring trend, need to carry out the secondary drawing-off of later process, otherwise can serious shadow
Ring the orientation of tow.
At least there are following 4 points logical disadvantages in the wire feeder described in above-mentioned Figure 12：First, due to being mechanical type wire feed, because
And wire feed rate is affected it is difficult to meet high speed spinning requirement；Second, because tow is contacted with roll body, thus on the one hand hold
Easily affect the orientation of tow, on the other hand can cause the injury to tow；Third, because the speed of high speed spinning is up to
6000-8000m/min, even more high, thus if the spinneret orifice of the spinneret of filament spinning component can not smooth spray（Impact spinning
Speed）, then the melt of die orifice exit such as acid fiber by polylactic spinning melt still occurs expanded situation, and expanded be impact
The bar of silk do big avoid, especially when wire feed rate and the spinning speed of wire feeder are unable to ideal adaptation, aforesaid expanded situation
Can show more serious；Fourth, due to being mechanical traction formula wire feed, thus do not simply fail to make tow produce obvolvent effect even
Tow can be caused to dissipate.
