Abstract
The invention discloses a polyphenylene sulfide (PPS) nascent fiber drafting and setting technology, which belongs to a PPS spinning technology and is used for producing PPS resin fibers. PPS finished fibers are produced by drafting, setting and winding PPS nascent fibers. Technological conditions comprise that the draft ratio is 5-7, the drafting speed is 300-350m/min, the drafting temperature is 120 plus or minus 2 DEG C and the hot setting temperature is 180 plus or minus 2 DEG C. The PPS nascent fibers are drafted and set in one step through serial V-shaped sandwich guide tubes which use heat conducting oil for heating at constant temperature. By adopting the process flow provided by the invention to draft and set the PPS nascent fibers in one step, not only can the process flow of fiber drafting be shortened, but also the working efficiency and the finished product rate of the drafted fibers are improved and the production cost is reduced.
Description
Technical field
The invention belongs to special fibre and manufacture field.
Background technology
High-performance polyphenylene sulfide has the heat endurance under excellent chemical proofing and high temperature, and has fire-retardant, insulation, radiation hardness and good mechanical performance.For expanding the scope of application of this material, the researchers of various countries are finding the new method making it fibration and use always.
Chinese patent CN91107114 discloses the process that a kind of potassium titanate fibre and polyphenylene sulfide compound make composite, in polycondensation vessel, first use six polyamine dispersant (doubling as polyphenylene sulfide synthesis solvent) to be disperseed by potassium titanate fibre under heating and stirring condition, then vulcanized sodium is added and paracide (P-DCB) is raw material, under base metal catalysts effect, (vulcanized sodium and paracide (P-DCB) are raw material to polycondensation production polyphenylene sulfide, under base metal catalysts effect, the fibrous composite of polyphenylene sulfide (PPS) and potassium titanate fibre is produced in polycondensation.But this method obtains the shortcoming that there is fibrous fracture intensity difference.US Patent No. 5401799 discloses a kind of polyphenylene sulfide based thermoplastic glass composite fibre with high-wearing feature, and provides composition of raw materials.
In Chinese patent CN200510022438.0, openly describe a kind of polyphenylene sulfide as-spun fibre drafting forming technique, being exactly the hot gas spring and the setting process that adopt current all chemical fibers in fact, is do not possess any novelty.
The object of the invention is the optimum process condition exploring polyphenylene sulfide fibre manufacture, simplify domestic and international chemical fiber drawing-off treatment process at present simultaneously, reduce unnecessary draw-off godet and heating draw-off godet, the constant object of drawing temperature reduces because the heating of heating draw-off godet or temperature temperature instability cause the unstability of the various performance indications of the finished fiber after drawing of fiber, thus become substandard products; Only in this way could improve fibrous finished product rate, thus reduce production cost and enhance productivity.
Another object of the present invention is, reduces the various draw-off godets of excessive use in traditional handicraft, and reduces the fracture ratio of polyphenylene sulfide as-spun fibre in drafting process, stablizes each performance indications of finished fiber.
Summary of the invention
The object of the invention is by following means realize.
Polyphenylene sulfide as-spun fibre drafting forming technique, produce polyphenylene sulfide fiber, employing technique is: P PS as-spun fibre-drawing-off-sizing-winding-production polyphenylene sulfide finished fiber, adopts following process conditions p-poly-phenyl thioether as-spun fibre drafting forming:
In the technological process of polyphenylene sulfide as-spun fibre drafting forming, adopt the series connection disposable drawing-off of interlayer conduit of heat-conducting oil heating constant temperature and sizing, wherein, heating duct is drafting tube, and heating duct is below calibration tube.Series connection interlayer catheter length is 2x600mm.And connect in " V " font, installing a diameter in the bottom of " V " font is
draw-off godet; Cut in the axis of series connection interlayer conduit slit a, b that a 6mm is convenient to fiber feeding simultaneously.
Under process conditions as above, the index such as fracture strength, folded intensity, abrasion resistance, serviceability temperature obtaining fiber is improved, the polyphenylene sulfide finished fiber that drawing-off is obtained like this not only can manufacture cloth, can also be mixed together for national defence and particular surroundings field with aramid fiber, hdpe fiber, carbon fiber, ceramic fibre.
Be all that conduction oil enters from the bottom 1 of drafting tube " V " font by temperature different heat-conducting oil heating constant temperature at interlayer drafting tube of the present invention and calibration tube, flow out from the left side 2 of drafting tube " V " font, input conduction oil constant temperature heating device.Conduction oil enters from the bottom 3 of calibration tube " V " font, flows out from the right 4 of drafting tube " V " font, input conduction oil constant temperature heating device.
As-spun fibre of the present invention feeds from the left side A of drafting tube " V " font, through installing diameter in the bottom of " V " font is
draw-off godet after, from the right B of " V " font drafting tube out, through a diameter be
draw-off godet after, input and feed from the left side C of calibration tube " V " font, through the bottom of " V " font install diameter be
draw-off godet after, from the right D of " V " font calibration tube out after, input rolling cylinder, becomes qualified finished fiber with regard to disposable by the drawing-off of polyphenylene sulfide as-spun fibre like this.
Accompanying drawing illustrates:
Fig. 1 polyphenylene sulfide as-spun fibre of the present invention draft process flow chart.
Fig. 2: the part performance indications after polyphenylene sulfide as-spun fibre of the present invention drawing-off.
