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 make the field.
Background technology
High-performance polyphenylene sulfide has the heat endurance under excellent chemical proofing and the high temperature, and has fire-retardant, insulation, radiation hardness and favorable mechanical performance.For enlarging the scope of application of this material, the researchers of various countries make it the new method that fibration is used in searching always.
Chinese patent CN91107114 discloses a kind of potassium titanate fibre and the compound process of processing composite of polyphenylene sulfide; In polycondensation vessel, at first use six polyamine dispersant (the synthetic solvent of using of double as polyphenylene sulfide) under heating and stirring condition, potassium titanate fibre to be disperseed; Adding vulcanized sodium and paracide (P-DCB) then is raw material; (vulcanized sodium and paracide (P-DCB) are raw material to polycondensation production polyphenylene sulfide, and the fibrous composite of polyphenylene sulfide (PPS) and potassium titanate fibre is produced in polycondensation under the base metal catalysts effect under the base metal catalysts effect.But this method makes the shortcoming that has the fibrous fracture intensity difference.U.S. Pat 5401799 discloses a kind of polyphenylene sulfide based thermoplastic glass composite fibre with high-wearing feature, and composition of raw materials is provided.
In Chinese patent CN200510022438.0, openly having introduced a kind of polyphenylene sulfide as-spun fibre drafting forming technology, is exactly to adopt the hot-stretch and the setting process of all chemical fibers at present in fact, is not possess any novelty.
The objective of the invention is to explore the optimum process condition that polyphenylene sulfide fibre is made; Simplify at present domestic and international chemical fiber drawing-off treatment process simultaneously; Reduce unnecessary draw-off godet and heating draw-off godet; The constant purpose of drawing temperature is to reduce the unstability that causes the various performance indications of the finished fiber behind the drawing of fiber because of the heating of heating draw-off godet or temperature temperature instability, thereby makes it become substandard products; Only in this way could improve the fibrous finished product rate, thereby reduce production costs and enhance productivity.
Another purpose of the present invention is, reduces the various draw-off godets that too much use in the 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 objective of the invention is to realize through following means.
Polyphenylene sulfide as-spun fibre drafting forming technology; Produce the polyphenylene sulfide fiber; Adopting process is: P PS as-spun fibre-drawing-off-typing-coiling-production PPS finished fiber, adopt following process conditions p-poly-phenyl thioether as-spun fibre drafting forming:
Drafting multiple 5-7 doubly
Draw speed 300-350m/min
160 ± 2 ℃ of draft temperatures
200 ± 2 ℃ of heat setting temperatures
In the technological process of polyphenylene sulfide as-spun fibre drafting forming, adopt series connection disposable stretching of interlayer conduit of heat-conducting oil heating constant temperature and typing, wherein preceding heating duct is a stretching tube, the heating duct of back is a calibration tube.Series connection interlayer catheter length is 2x600mm.And being " V " font and connecting, is 30 draw-off godet at diameter of the bottom of " V " font installation; Be convenient to slit a, the b that fiber feeds at the 6mm that axially cuts of series connection interlayer conduit simultaneously.
Under process conditions as above; Obtaining indexs such as the fracture strength of fiber, folded intensity, abrasion resistance, serviceability temperature is improved; The polyphenylene sulfide finished fiber that makes of drawing-off not only can manufacture cloth like this, can also be mixed together with aramid fiber, hdpe fiber, carbon fiber, ceramic fibre to be used for national defence and particular surroundings field.
At interlayer stretching tube of the present invention and calibration tube all is by the different heat-conducting oil heating constant temperature of temperature, and conduction oil gets into from the bottom 1 of stretching tube " V " font, flows out input conduction oil constant temperature heating device from the left side 2 of stretching tube " V " font.Conduction oil gets into from the bottom 3 of calibration tube " V " font, flows out input conduction oil constant temperature heating device from the right 4 of stretching tube " V " font.
As-spun fibre of the present invention is from the left side A feeding of stretching tube " V " font; Pass through after installation diameter in the bottom of " V " font is 30 draw-off godet; Come out from the right B of " V " font stretching tube, after being 100 draw-off godet through a diameter, input is from the left side C feeding of calibration tube " V " font; Pass through after installation diameter in the bottom of " V " font is 30 draw-off godet; After coming out from the right D of " V " font calibration tube, input rolling tube becomes qualified finished fiber with regard to disposable with the drawing-off of polyphenylene sulfide as-spun fibre like this.
