Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation methods of ultra high density water-proof breathable properties fiber, overcome
In the prior art spinning break number is more in process of production for ultra high density water-proof breathable properties fiber, production stability compared with
Difference, the higher problem of yarn unevenness.
The present invention is achieved through the following technical solutions.
A kind of preparation method of ultra high density water-proof breathable properties fiber, the production technology include following step
It is rapid:
(1) sorting selects: p-phthalic acid (PTA) and ethylene glycol (EG) is used, by being made into after polymerization esterification polycondensation
Fine high polymer-polyethylene terephthalate (PET) melt, the melt characteristic viscosity are 0.627 ~ 0.629dl/g,
Content of carboxyl end group is 36 ~ 38mol/t, and for diethylene glycol content less than 1.20%, content of titanium dioxide is 0.22% ~ 0.24%；
(2) technological process of production: by ethylene glycol terephthalate (PET) melt successively pass through smelt spout → booster pump →
Melt cooler → static mixer → melt distributing valve → spinning manifold → metering pump → veneer filament spinning component → spinneret →
Circular blow air duct cooling → oil nozzle oils → and path → first draw-off godet → pre- network → second spinning reel → coiling and molding → POY →
Automatically silk is fallen, obtains ultra high density water-proof breathable properties fiber；Wherein the temperature range of melt body delivery pipe is 287~290
℃；The temperature of spinning manifold is 291-292 DEG C；The initial pressure of the veneer filament spinning component is 165-18.3 Mpa；It is described
The diameter of spinneret be 66 mm, spinneret orifice diameter thereon is 0.18mm, and the length of spinneret orifice is 0.55 mm；The ring
The size of Blowing drum middle ring blowing air pressure is 20-30 Pa；Distance of the oily frame apart from spinneret is 900-1000 mm；Spinning speed
For 2750~2780 m/min；The speed difference of first draw-off godet and second spinning reel is 0~3 m/min, second spinning reel and spinning
The difference of silk speed is 0~5 m/min；
(3) automatic packaging: ultra high density water-proof breathable properties fiber will be obtained and pass through automatic packing processes；
Melt comes out from pet reaction terminal polymerization kettle and reaches spinning manifold spinneret, flows in melt pipe always.In this mistake
Journey, since the heat generated by heating medium for heating and itself flowing is influenced, thermal degradation can occur for melt, lead to polyester viscosity
Decline, content of carboxyl end group increase, and generate gel particles, and polyester color turns to be yellow when serious, seriously affect normal spinning production.Melt
Degradation is mainly influenced by two big factors: first is that the residence time；Second is that melt conveying temperature has designed installation due to conveyance conduit
It finishes, can not change, therefore the more difficult residence time for changing melt, melt conveying temperature can only be controlled, degradation is made to reach minimum.
If melt conveying temperature is too low, fluidity of molten can be made to be deteriorated, equally will affect the uniformity of polyester quality, it can be in spinning
In cause broken end etc. abnormalities.Thus, when selecting melt conveying temperature, to guarantee having the same of good rheological characteristic
When viscosity drop it is as minimum as possible.Referring to having fine-denier variety production process conditions and knowhow, by melt conveying pipeline temperature
Range is scheduled on 287~290 DEG C.
Component is the core of spinning, to guarantee the good extrusion performance of melt, the arrangement mode of spinneret orifice, aperture, hole
Draw ratio is all critically important.The present invention selects diameter for the spinneret of 66mm, 72 spinnerets of being arranged in a manner of concentric arrays
Hole.Pore size be mainly by melt by spinneret orifice when shear stress and spin-draw ratio determine, it is thin for terylene
For denier POY, aperture should be smaller than the aperture of common specification, can keep lesser jet stretch multiple, is convenient for normal spinning.
This test the hole diameter of spinneret selects 0.18mm.As for draw ratio, during high speed spinning, the buoyancy effect of melt is more aobvious
It writes.In order to reduce buoyancy effect, melt temperature can be improved, to reduce melt viscosity, reduce slack time, spray can also be increased
Filament plate draw ratio achievees the purpose that reduce buoyancy effect, avoids melt extrusion to increase residence time of the melt in spinneret orifice
Melt fracture is caused when spinneret orifice.But draw ratio is too big, and it is excessively high to will cause spinneret back pressure, and component service life shortens, and
The very thin spinneret in aperture is difficult to clean up.The draw ratio of spinneret orifice will be greater than 3, thus this test on binding isotherm
The Design of length of spinneret orifice is 0.55mm.
For 119dtex/172f kind due to diameter very little, bending stiffness is seldom, fabric hand particularly soft, the ratio of fiber
Surface area is big, such as blows cooling using side-blown, is difficult that tow cooling is uniform, and strand shake is big, will lead to tow evenness fault
Rate rises, and broken end increases, and the blowing of Ba Mage inner ring is relatively suitble to the cooling of multiporous fine denier yarn, and therefore, the present invention selects in Ba Mage
Ring wind quenching method.When wind pressure is smaller, cooling air quantity is inadequate, can not uniformly be fully cooled tow, so that the item of tow is dry not
Even rate and broken end number increase；When wind pressure control is excessive, tow cooling is very fast, and freezing point moves up, tow concussion aggravation, rapid
Dynamic air-flow, which travels to stretcher strain area, will lead to spinneret face cooling, and broken end increases, and yarn unevenness rises, and synthesis is examined
Consider, wind pressure control is advisable in 25Pa or so.
Oil nozzle is fixed in spinning chamber using oily frame, and the height of oily frame can be adjusted freely.Because the height of oily frame is to spinning
The influence of tension is very big, and the degree of orientation that excessively high spinning tension will lead to silk is big, to induce crystallization, makes the freezing point distance of silk
The Distance Shortened of spinneret, in order to guarantee the physical property of silk and the uniformity that oils, it is ensured that the appearance of spinning cake is well and stable
Full-rolling rate avoids strand from oiling irregular, causes strand and filar guide frictionally damage, the silk that largely floats is generated, according to previous fine denier filament
Production development experience, determine that the height of boundling oil frame is that (distance of the i.e. oily frame apart from spinneret be 900-1000 mm or so
900-1000 mm), it oils using Germany's L-165 oil nozzle.
The size of spinning speed has a very large relationship the physical index and production stability of silk, raw according to fine denier POY
The empirical data of production determines the range of spinning speed between 2750~2780m/min.
Preferably, the specification of the circular hole fiber is 119dtex/72F.
Preferably, the oil nozzle oils, finish uses s&s company of Germany L-165 finish.This finish can increase
The cohesive force of tow reduces the electrostatic that friction generates, and application effect is preferable in the production of pervious Fine-denier flat yarn.
Preferably, the circular blow wind-warm syndrome is controlled at 19~20.5 DEG C.
Preferably, the spinneret orifice is arranged on spinneret in a manner of concentric arrays, the quantity of spinneret orifice is 72
