But, adopt gel method to produce aramid IIII fiber and but have no relevant report up to now.
Summary of the invention
The object of the present invention is to provide one with known polymer fluid for raw material, employing gel spinning technology continous-stable manufactures the method for aramid IIII fiber product.The method not only effectively can improve spinning speed, and further increases fibrous mechanical property, improves while achieving production efficiency and properties of product.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of manufacture aramid IIII fiber gel spinning process, is characterized in that processing step is as follows:
A, spinning solution are measured through measuring pump and are extruded formation thread by spinning head and enter one section of height 5 ~ 30mm air layer;
B, entered in the first order solidification liquid of low concentration become gelatinous fibre by the thread of extruding of air layer, fiber adopts negative stretch in first order solidification liquid, and negative stretch ratio is-40 ~-90%;
C, gelatinous fibre enter in the second level solidification liquid of higher concentration, and through plasticization drawing and simultaneously further solidification forming is the fiber with state of aggregation primary structure, and gelatinous fibre adopts to plastify and just stretches in the solidification liquid of the second level, and positive extensibility is 80 ~ 160%;
D, through the aramid IIII fiber with state of aggregation primary structure of secondary solidification forming by washing, oil, drying process obtains aramid IIII fiber precursor;
E, aramid IIII fiber precursor become finished fiber after HEAT SETTING process.
The intrinsic viscosity of the spinning solution polymer described in steps A is 5 ~ 9dL/g.Within the scope of this intrinsic viscosity, both can not be too large because of intrinsic viscosity, polymer dissolution performance declines, and causes production efficiency to reduce; Also can not be too little because of intrinsic viscosity, and fibre property is reduced.
Described in steps A, the air layer of height, both can avoid because air layer height is too high, and it is serious by air flow effect that thread extruded by spinning head, the problem of easy doubling; There will not be again because air layer is too low, be subject to solidification liquid influence of fluctuations, cause the situation of spinning instability.Wherein air layer height is preferably 10 ~ 20mm.
First order solidification liquid described in step B is the mixed liquor of organic solvent and water.Described organic solvent is any one in ethanol, DMA, DMF, 1-METHYLPYRROLIDONE.
The content of organic solvent described in first order solidification liquid is 1 ~ 20%wt.Organic solvent content is too high, causes spinning head to extrude thread coagulation result in solidification liquid and is deteriorated, thus be unfavorable for the enforcement of postorder stretch orientation technique.Wherein in first order solidification liquid, organic solvent content is preferably 5 ~ 15%wt.
Under the negative stretch ratio of in stepb-40 ~-90%, both can not be too large because of negative stretch ratio, cause and thread formation gel state generation deleterious effects is extruded to spinning head; Again can not be too little because of negative stretch ratio, cause fiber normally cannot draw spinning.
Second level solidification liquid described in step C adopts has the organic solvent of same composition and the mixed liquor of water with first order solidification liquid.Described organic solvent is any one in ethanol, DMA, DMF, 1-METHYLPYRROLIDONE.
The content of organic solvent described in the solidification liquid of the second level is 20 ~ 40%wt.As the organic solvent content in the solidification liquid of the second level is too low, then the tensility of gelatinous fibre can reduce, thus affects fibre property; And organic solvent content is too high, solidification liquid and gelatinous fibre internal solvent concentration difference can be caused again too large, and coagulation result is deteriorated, and the organic solvent of high-load also can increase postorder washing procedure load, is difficult to thus remove the impurity in primary filament completely.Wherein in the solidification liquid of the second level, organic solvent content is preferably 25 ~ 35%wt.
Under the positive extensibility of 80% ~ 160% described in step C, both can not be too low because of draw ratio, affect the structural behaviour of finished fiber; Again can not be too high because of draw ratio, and spinning process stability will be worsened, and then fiber quality is impacted.
The washings that washing procedure described in step D adopts are deionized water, and temperature is 80 ~ 95 DEG C.Temperature is too low, and clean result is not good.
The heat treatment method that HEAT SETTING process described in step e is namely conventional, or the method that heat treatment combines with hot-stretch.
Described heat treatment and hot-stretch device are conventional path equipment.Heat treatment temperature is 350 ~ 390 DEG C, and hot-stretch temperature is 390 ~ 430 DEG C.
The invention has the advantages that:
1, relative to conventional wet lay spining technology, the present invention can increase substantially Fiber spinning speeds, improves fibre production efficiency.Gel spinning speed of the present invention reaches 30m/min ~ 100m/min, while raising fibre production efficiency, effectively reduces fiber manufacturing cost.Through putting into practice further proof, adopt inventive gel spin processes to manufacture aramid IIII fiber, not only stable processing technique, and fibre property and exterior quality are held concurrently excellence.
2, gel spinning technology of the present invention further increases fibrous mechanical property.Compare with the fiber of wet spinning technology manufacture, the aramid IIII fiber mechanical property that gel spinning technology manufactures is more excellent, reaches 5.8GPa.In the present invention, spinning head is extruded thread and form gel fast in first order solidification liquid, then enter in the solidification liquid of the second level and fully stretch and solidification forming, be solidified into state of aggregation primary structure, stability and the fiber product quality of spinning technique effectively improve.
3, the apparent state of fiber of the inventive method manufacture is better.Wet spinning technology is owing to limiting by operational characteristic, and the fiber surface of production exists gully, and lousiness phenomenon is difficult to avoid completely.The aramid IIII fiber that gel spinning technology manufactures is without lousiness, and smooth surface, fiber softening, monofilament disperses, and the apparent state of fiber is more excellent.
