Abstract
The invention provides a hollow polyphenylene sulfite short fiber multistage ring air-cooling process. The process comprises the following steps that: a melt extrudes out of a spinning hole, multistage ring air cooling is performed through a plurality of air ducts, wherein five air ducts have five different wind speeds, namely a first wind speed of 0 to 4 m/min, a second wind speed of 0 to 3.5 m/min, a third wind speed of 0 to 3 m/min, a fourth wind speed of 0 to 2.8 m/min, and a fifth wind speed of 0 to 2.5 m/min, after multistage intake air is blown into a ring air-cooling device, and uniform air flow after passing through the ring air-cooling device is blown to tows extruded from a spinning plate, so that the cooling process is completed. By using the 5-level blowing process, the air speed can be gradually increased, the cooling effect can be reflected gradually, and the stress of molecules can be released gradually, so that a curling effect is avoided, and a hollow effect of polyphenylene sulfite short fibers is improved. Compared with the common ring air-cooling process with one-level speed, the multistage ring air-cooling process has 5 speed levels, and a gradual cooling effect is achieved.
Description
Technical field
The present invention relates to a kind of ring blow moulding, particularly a kind of multistage ring of hollow polyphony thioether short fiber blows process for cooling, belongs to chemical fibre and manufactures field.
Background technology
The main application of polyphony thioether short fiber manufactures filter cloth, because be solid fibers, so unit grammes per square metre is high.Use cost is high on the one hand to use client, increases entreprise cost; The filter cloth Heavy Weight done on the one hand, difficulty of construction is high.In order to reduce unit grammes per square metre, polyphenylene sulfide cavitation has become the concern receiving more and more people, becomes the important topic of present stage polyphony thioether short fiber production.
When polyphony thioether short fiber is produced, high temperature is that the melt of viscosity flow shape is extruded from spinneret orifice, through the quenching postforming of certain humiture.In spinning process for cooling, the key factor in the selection of melt spinning cooling condition and control room terylene as-spun fibre forming process, it on finished silk strong, stretch, fiber number, degree of crystallinity, the degree of orientation and dyeability have conclusive impact.
Cold air blast velocity is the key factor affecting spinning face shape.When adopting traditional ring to blow, when tow is out cool it with same wind speed from manifold.Demeanour is too high or too low, and the section irregularity of precursor is all larger.When wind speed is too low, the outer field cooling condition of tow wind is widely different, and plastic zone extends, and freezing point moves down, thus causes the section irregularity of precursor to increase.When wind speed is too high, blows cylinder air-flow out from ring and not only penetrate tow arrival tow center, and also have remaining kinetic energy, cause in tow center turbulence mixing, meanwhile, upper punch air-flow is forming strong eddy current near spinnerets place, cause strand to rock indefinite, affect the quality of precursor.
Current polyphony thioether short fiber production technology, link is blown at ring, adopted ring blow moulding step too simple, its quench air velocity is unadjustable, uses single wind speed that the molecular mobility of polyphenylene sulfide can be made poor when ring blows, and when spinning doughnut, wind speed is too large, molecule STRESS VARIATION can be caused, and cause the dry distortion of the bar of strand, form rolled efficiency, be so difficult to the effect realizing polyphenylene sulfide cavitation.
Summary of the invention
The object of the invention is to overcome above deficiency, providing a kind of multistage ring of hollow polyphony thioether short fiber to blow process for cooling.
Object of the present invention realizes like this:
The multistage ring of a kind of hollow of the present invention polyphony thioether short fiber blows process for cooling, wherein, comprise the following steps: melt is extruded from spinneret orifice, multistage ring blast-cold is carried out but through multiple intake stack, five intake stacks adopt five kinds of different wind speed respectively, comprise one-level wind speed 0 ~ 4 m/min, secondary wind speed is 0 ~ 3.5 m/min, force 3 wind speed is 0 ~ 3 m/min, level Four wind speed is 0 ~ 2.8 m/min, Pyatyi wind speed is 0 ~ 2.5 m/min, after multistage air intake enters quench device, the tow extruded from spinnerets is blowed to uniformly after quench device current-sharing, thus complete the process of cooling.
Compared with prior art, beneficial effect of the present invention is:
Adopt 5 grades of blowing techniques, wind speed is amplified step by step, allow the effect of cooling embody step by step, the stress of molecule discharges step by step, avoids producing rolled efficiency, improves the cavitation effect of polyphony thioether short fiber.Blow 1 grade of speed governing of process for cooling compared to common ring, the present invention realizes 5 grades of speed governing, cools step by step.
Through multi-air intake ring dry different wind speed cooling after, can prevent the too low freezing point that makes of wind speed from moving down, also can prevent that wind speed is too high remaining kinetic energy, avoid occurring in the turbulence mixing of tow center, improve the quality of precursor.
Each air inlet gives different wind speed, greatly improves the end product quality of precursor, improves the quality of finished silk.
