Description
The present invention relates to a kind of high-performance polyphenylene sulfide fiber tectosome and its manufacturing methods and purposes.
Diaphragm cloth is the essential core material of water electrolyser, and water electrolysis hydrogen producing, oxygen generating plant are widely used in the manufacturing fields such as military affairs, petrochemical industry, steel again, and domestic main alkaline water electrolytic hydrogen-preparing equipment manufacturer still uses asbestos cloth as diaphragm at present.But with the propulsion and technological progress of process of industrialization, during production practices, people gradually recognize asbestos diaphragm, and there are some problems.Asbestos itself and nonhazardous, from its fiber, this is that almost invisible fiber can swim in air for a long time after these tiny fibers releases, be easy to be sucked by human body for a kind of very tiny, naked eyes for its maximum harm.Therefore, international community can all increase the R&D intensity to new types of diaphragm material, and in China, diaphragm cloth is always the essential core material of water electrolysis equipment, to adapt to increasingly fierce international competition, product is pushed to international market, replaces asbestos diaphragm to be determined to win with non-asbestos diaphragm cloth of new generation.At present, asbestos diaphragm is replaced using diaphragm cloth made from polyphenylene sulfide fibre, although solving the problems such as pollution, air-tightness is low, but if since the fibre number that woven PPS diaphragm cloth uses is improper and proportion between single thread and strand twist is inappropriate, the pore size that will lead to diaphragm obtained is inhomogenous, air-tightness is bad.
If Chinese publication CN101372752 discloses non-fabrication cloth made of a kind of common polyphenylene sulfide fibre of use, then pass through 70~130 DEG C, 90~98% H2SO4It carries out sulfonation to handle 20~40 minutes, then with 30% potassium hydroxide treatment, finally obtains high temperature resistant alkaline water electrolytic cell barrier diaphragm.In the invention, since the imbibition rate of non-woven cloth is relatively strong, after strong acid treatment, need to consume the water resource and chemicals of a large amount of preciousnesses in the process of cleaning, scavenging period is also longer, and complex operation, easily pollutes the environment.Safety simultaneously is also poor, should not carry out industrialized production.
As Chinese publication CN103938337A discloses highly dense woven fabric made of a kind of common 2.2T polyphenylene sulfide fibre of use, then the hydrophilicity of polyphenylene sulfide diaphragm is assigned by the method for the hydrophilic processing of plasma, finally obtain the alkaline-resisting polyphenylene sulfide diaphragm of high temperature resistant, the invention causes the air-tightness of diaphragm obtained bad since the proportion between the filament denier and single thread and strand twist that use is inappropriate.In addition to this, due to using
The PPS diaphragm cloth of the hydrophilic processing method processing of plasma, hydrophilic effect is not so good and timeliness is short, and the diaphragm is caused not meet the needs of production really.
For another example China publication CN101195944 discloses a kind of no asbestos environment-friendly and energy-efficient diaphragm, uses with one of polyetheretherketonefiber fiber, polyphenylene sulfide fibre, polypropylene fibre, two or three as woven fabric made of raw material weaving.Although the air-tightness of the diaphragm cloth meets the standard requirements of asbestos diaphragm, since the water imbibition of above-mentioned chemical fibre is poor, causes diaphragm cloth hydrophily obtained poor, can not really meet requirement.
Summary of the invention
A kind of the purpose of the present invention is to provide air-tightness higher, the better high-performance polyphenylene sulfide fiber tectosome of hydrophily.
Another object of the present invention is to provide a kind of simple process, save the energy, no pollution to the environment high-performance polyphenylene sulfide fiber tectosome manufacturing method.
In order to achieve the above object, composition of the invention is as follows:
(1) polyphenylene sulfide fibre tectosome of the invention is the woven fabric that the polyphenylene sulfide fibre for being 0.1~12 μm by cross-sectional diameter is formed, and the maximum diameter of hole of the polyphenylene sulfide fibre tectosome is 20 μm or less.
(2) constituting the warp and weft of the polyphenylene sulfide fibre tectosome of above-mentioned (1) is the polyphenylene sulfide spun yarn processed by hydrophiling.
(3) average pore size of the polyphenylene sulfide fibre tectosome of above-mentioned (1) is 5 μm hereinafter, wherein 6 μm of holes below account for 90% or more of fiber body structure all well.
(4) singles yarn count for constituting above-mentioned (1) is 21~60s.
(5) the yarn twist factor for constituting above-mentioned (1) is 180~350.
(6) warp twist for constituting the polyphenylene sulfide fibre tectosome of above-mentioned (1) is more than or equal to the twist of weft yarn.
(7) ratio of the twist of the twist and polyphenylene sulfide single thread of polyphenylene sulfide yams is 0.2~1.0 in the polyphenylene sulfide fibre tectosome of any one of above-mentioned (4)~(5).
(8) air-tightness of the polyphenylene sulfide fibre tectosome of above-mentioned (1) is constituted in 400mmH2O or more.
(9) surface resistance for constituting the polyphenylene sulfide fibre tectosome of above-mentioned (1) is 60m Ω .cm2Below.
The beneficial effects of the present invention are: the present invention is appropriate due to using the ratio between the polyphenylene sulfide fibre and single twist and strand twist that fineness is 0.1~12 μm, the defect that the aperture for overcoming the prior art is inhomogenous, air-tightness is low, the aperture of PPS woven fabric obtained can be made small and be evenly distributed, this, which allows for polyphenylene sulfide fibre tectosome of the invention, not only has the characteristics that air-tightness height, good hydrophilic property, also has simple process, saves
The characteristics of energy, no pollution to the environment.Polyphenylene sulfide fibre tectosome of the present invention can be applied to electrolysis unit diaphragm, high-temp liquid filters, in insulating materials.
Polyphenylene sulfide fibre tectosome of the present invention is the woven fabric that the polyphenylene sulfide fibre for being 0.1~12 μm by cross-sectional diameter is formed, and the maximum diameter of hole of the polyphenylene sulfide fibre tectosome is 20 μm or less.In all fabric tissues, tabby intertwined point is most, and tightness is maximum, and it is advantageous to plain fabrics.If the cross-sectional diameter of polyphenylene sulfide fibre is less than 0.1 μm, since fiber is too thin, it will appear fiber in carding process and comb not open, broken filament occurs that resultant yarn is bad, the excessive phenomenon of cotton knot, to influence the quality of yarn.If weaved with the yarn, it is possible to so that the fault of PPS cloth cover is excessive, influence thickness, the aperture of fabric, to cause the aperture of fabric, in uneven thickness, further result in the poor air-tightness of fabric；If the cross section of polyphenylene sulfide fibre is directly through being greater than 12 μm, since the diameter of fiber is excessively thick, monofilament yarn is really up to the mark, it is not easy resultant yarn, in addition it is difficult slightly to also bring along weaving excessively for yarn, the aperture for also resulting in gained fabric becomes larger, and the air-tightness of fabric is deteriorated, and hydrogen, the oxygen purity for eventually leading to preparation are bad；In view of composite factors such as hydrophilic processing effects during PPS fabric air-tightness and post-processing, preferably 6~10 μm of the cross-sectional diameter of polyphenylene sulfide fibre, more preferable 6~8 μm.
The warp and weft for constituting the polyphenylene sulfide fibre tectosome is the polyphenylene sulfide spun yarn processed by hydrophiling.The filling yarn of polyphenylene sulfide fibre tectosome of the invention is all made of short fiber yarn, compare long fibre yarn, spun yarn has that coherent between single fiber is strong, will not because yarn construction caused by gap between fiber increase, to influence aperture and the air-tightness of fabric.Spun yarn used in the present invention can be single thread, be also possible to the folded yarn for having single thread to constitute, preferably doubled yarn.In order to guarantee that polyphenylene sulfide fibre tectosome has excellent hydrophilicity, preferably through hydrophilic finished polyphenylene sulfide spun yarn line.Here hydrophiling refers to the hydrophilic radical for increasing polyphenylene sulfide fibre surface by plasma, sulfonation or the method for grafting, such as hydroxyl, carboxyl, carbonate, sulfate groups etc..The grafting rate of the polyphenylene sulfide yams of hydrophilized processing is 0.1~3%, and grafting rate is preferably 0.5~3%.
The maximum diameter of hole of polyphenylene sulfide fibre tectosome of the invention is 20 μm or less, if the maximum diameter of hole of polyphenylene sulfide fibre tectosome is greater than 20 μm, then the aperture of polyphenylene sulfide fibre tectosome is excessive, when will lead to its use in hydrogen producer, hydrogen, oxygen bubble easily pass through the gap of fiber body structure, reduce the purity of pure gas.The maximum diameter of hole of polyphenylene sulfide fibre tectosome is 20 μm hereinafter, in order to make the uniform aperture of polyphenylene sulfide fibre tectosome, size distribution or accumulation of aperture, concentrate, and polyphenylene sulfide fibre tectosome is most
Preferably 15 μm of large aperture is hereinafter, in order to enable the aperture of fiber body structure is more uniform, the distribution of size of aperture is more assembled, more concentrated, preferably 12 μm or less of the maximum diameter of hole of polyphenylene sulfide fibre tectosome.
The average pore size of polyphenylene sulfide fibre tectosome of the present invention is 5 μm hereinafter, wherein 6 μm of holes below account for 90% or more of fiber body structure all well.Within the above range, it is ensured that air-tightness is high, such gas molecule, bubble are difficult to pass through, to prevent the mixing of anode side gas and anode side gas, purity and the safety to guarantee gas are good for the average pore size control of polyphenylene sulfide fibre tectosome.If the average pore size of polyphenylene sulfide fibre tectosome is greater than 5 μm, since the aperture of woven fabric is excessive, for woven fabric in use, not having the effect of isolation in hydrogen producer, hydrogen, the oxygen purity for eventually leading to preparation are low, and the requirement of client is not achieved.In order to guarantee the air-tightness requirement of woven fabric of the present invention, the luminous efficiency of gas is improved simultaneously, and improve the purity for generating gas, under the premise of in 5 μm of average pore size or less ranges, optimize weaving condition, the uniformity for improving aperture, makes aperture account for 90% or more of all well, preferably 95% or more in 6 μm of holes below.
It is 200~310 that the singles yarn count for constituting polyphenylene sulfide woven fabric, which is selected as 21~60s, twist factor α,.The number of single thread can guarantee that obtained PPS fabric pore size is small and uniform, air-tightness is high in above range, and gained woven fabric can also be made good in the hydrophilic processing effect in rear road.If singles yarn count is too low, yarn is too thick, causes the aperture of woven fabric big, and the air-tightness of woven fabric is small, and hydrogen, the oxygen purity for eventually leading to preparation are bad；If singles yarn count is excessively high, very thin yarn certainly will be needed, will lead to production process difficulty in this way.In addition, the twist factor of single thread can guarantee that the fluffy sense of obtained PPS yarn is moderate within the above range, so that the aperture of woven fabric is small and uniform, air-tightness is high, it is also possible that hydrophilic processing effect of the woven fabric in rear road is good.If the twist factor of yarn is too small, the twist of yarn is too low, causes the strength of yarn low, when weaving easy broken yarn, the strength of fabric obtained will be lower；If the twist factor of yarn is excessive, the twist of yarn is too high, and gap is obvious at the intertwined point of fabric, aperture increases；On the other hand, the interfibrous gap of yarn interior can also become smaller, and the pore size so as to cause entire woven fabric is inhomogenous, and air-tightness reduces.
The yarn twist factor for constituting the polyphenylene sulfide woven fabric is 180~350, if if the twist factor of yarn is too low, causing the angle of twist of single fiber small, interfibrous cohesive force reduces, the strength reduction of yarn causes the strength in weaving process due to yarn low, it is difficult to weave；If if the twist factor of yarn is excessively high, causing interfibrous cohesive force excessive, the strength of yarn is reduced, and is easy easily occur handle in weaving process, is not easy to weave.
In weaving when machine, the warp tension ratio weft yarn Weft Insertion that warp thread is subject to is big, and in order to guarantee the weaving efficiency of polyphenylene sulfide fabric, so that the construction of fabric is close, aperture is small and uniform pore diameter is good, preferably comprises polyphenyl of the present invention
The warp twist of sulfide fibers tectosome is more than or equal to the twist of weft yarn.Warp twist is bigger, it is ensured that the intensity of warp thread improves aperture opening ratio, is conducive to weaving.Weft yarn selects the spun yarn of the slightly lower twist, and yarn is fluffy, can make up because warp twist improves bring aperture increases and irregular defect.
The ratio of the twist of the twist and polyphenylene sulfide single thread of polyphenylene sulfide yams of the invention is 0.2~1.0, the ratio of yarn twist and single twist can guarantee that the aperture of woven fabric is uniform within the above range, it is also possible that woven fabric is in hydrophilic process, the hydrophilic radical number connected is more, the liquid holdup of woven fabric will be made to increase, it is thicker in the moisture film that woven fabric surface layer is formed, effectively bubble can be prevented to pass through, so that gas purity increases.If the ratio of the twist of polyphenylene sulfide yams and single twist is too small, the twist of yarn is bound to reduce, and causes the intensity of polyphenylene sulfide yams low, and the strength of polyphenylene sulfide woven fabric obtained will be lower, and is easy to be the worse for wear to will lead to woven fabric；If the ratio of the yarn twist of polyphenylene sulfide and single twist is excessive, it will lead to the interfibrous gap of yarn interior to become smaller, pore size so as to cause entire woven fabric is inhomogenous, and air-tightness lowly causes the aperture of woven fabric inhomogenous, and makes the hydrophilic radical number connected few.
The air-tightness of polyphenylene sulfide fibre tectosome of the present invention is in 400mmH2O or more.When the polyphenylene sulfide fibre tectosome is applied to water electrolyser, meeting 400mm or more H2Under O pressure, keep 2min it is air-locked under the conditions of, the air-tightness requirement of practical water electrolyser septation cloth can be substantially met, and simultaneously in view of diaphragm cloth can have excellent air-tightness, ion by efficiency and the processability of diaphragm cloth.If air-tightness is less than 400mmH2O pressure, is unable to satisfy diaphragm primary demand, and the gas purity of generation is impacted.
The surface resistance of polyphenylene sulfide fibre tectosome of the present invention is 60m Ω .cm2Hereinafter, it is preferred that surface resistance is 10m Ω .cm2Below.If the surface resistance of polyphenylene sulfide fibre tectosome is greater than 60m Ω .cm2If, cause the impedance of fabric big, increases the consumption of electric energy, and production cost also increases.
The alkali absorbing rate of polyphenylene sulfide fibre tectosome of the present invention is 70~200%, if the alkali absorbing rate of polyphenylene sulfide fibre tectosome is too low, is difficult to form moisture film in lye or moisture film is excessively thin, not can effectively stop passing through for bubble, to reduce the purity of gas；If the alkali absorbing rate of polyphenylene sulfide fibre tectosome is excessively high, the construction of woven fabric certainly will be caused more open, gap increases, to influence the performance of diaphragm.In view of the hydrophily and construction of polyphenylene sulfide fibre tectosome, the alkali absorbing rate preferably 85~180%, more preferable 100~160% of polyphenylene sulfide fibre tectosome of the present invention.
High-performance polyphenylene sulfide fiber tectosome of the invention is applied in hydrogen producer, and main function is that ion can pass through, and gas molecule cannot pass through.Since purity requirement of the different clients to the hydrogen, oxygen of system is different, so the pore size and air-tightness requirement to fabric are also different, the type and tissue nothing of this and fabric
It closes, as long as customer requirement can be met by not penetrating mutually between gas molecule.
The manufacturing method of high-performance polyphenylene sulfide fiber tectosome of the invention, includes the following steps:
(1) polyphenylene sulfide fibre that cross-sectional diameter is 0.1~12 μm cotton spinning: is passed through into opening picking-cotton carding-drafting-rove, the polyphenylene sulfide single thread that number is 20~60s, twist factor α is 200~310 is made by drawing-off in rove, the polyphenylene sulfide yams that number of share of stock is 1~6 strand are made using winder-doubling-twisting-thermal finalization；
(2) weaving process: polyphenylene sulfide yams obtained are gaited-plug in reed-weaving by warping-, and coverage coefficient is made as 2400~2900 polyphenylene sulfide woven fabric；The coverage coefficient of woven fabric is the parameter for characterizing fabric tightness degree, coverage coefficient is higher, fabric is closer, venting quality and aperture are with regard to smaller, if the coverage coefficient of plain fabric is lower than 2400, since fabric compactness is inadequate, cause the air-tightness of fabric low, woven fabric is difficult to stop passing through for gas in this way, thus it cannot be guaranteed that the safety of the purity and manufacturing process of gas；If the coverage coefficient of plain fabric is higher than 2900, there is higher requirement to loom, weaving is difficult.The coverage coefficient of woven fabric preferably 2600~2800；
(3) postfinishing process: polyphenylene sulfide woven fabric obtained is subjected to concise, washing, is dried, thermal finalization at 180~200 DEG C；Above-mentioned concise, thermal finalization optimum experimental condition is as follows:
A. the scouring agent used: YK30 12g/L, YS66 3.0g/L, YK37 2.0g/L,
B. concise bath temperature degree: 1 40~50 DEG C of slot, 70~80 DEG C of 2 slot, 95~105 DEG C of 3 slot,
C. speed: 10~14m/min,
D. heat setting temperature: 180 DEG C~210 DEG C,
E. thermal finalization speed: 10~14m/min；
(4) fabric after sizing hydrophilicity-imparting treatment technique: is passed through into plasma or/and the hydrophilic processing of sulfonation, final finished product.By the way that fabric is carried out plasma or/and the hydrophilic processing of sulfonation, hydrophilic radical can be connected in PPS fiber surface, the wetting speed of PPS woven fabric can be increased, while the liquid holdup of PPS woven fabric can also be increased, so that in use, the production efficiency of gas improves and purity is high.By plasma or/and the hydrophilic processing of sulfonation, the grafting rate that fabric is made has difference, and the preferably grafting rate of PPS woven fabric is 3.0~8.0%.
The above-mentioned hydrophilic processing method of plasma, including atmospheric plasma processing, low pressure plasma processing, the method of atmospheric plasma processing includes glow discharge, voltolising, corona discharge, wherein glow discharge includes DC current, high-frequency current, microwave radiation, the gas of low pressure plasma working process can be oxygen, argon gas, nitrogen etc., a possibility that in view of processing, the stability of processing, the efficiency of processing, plasma parent
Water processes preferred atmospheric plasma aura direct-current discharge, and the condition of atmospheric plasma aura direct-current discharge is, 5~15v of voltage, 12~18A of electric current, the oxygen element connected content account for the 15~25% of measured constituent content.After plasma process, on the surface of PPS fiber, indent and convex pitting is generated, the capillary effect and water imbibition of PPS woven fabric can be increased in this way, in addition to this, hydrophilic radical is connected on the surface layer of PPS fiber, hydrophilic radical is sulfate radical, carboxylate radical, carbonate, hydroxyl, carbonyl etc., and the effect of these hydrophilic radicals connected can increase the absorption speed of PPS fiber, can also improve the purity of hydrogen, oxygen.
When fabric while using plasma and sulfonation after sizing are processed, the fabric after sizing carries out corona treatment, so that PPS yam physical etches, so that forming concave-convex hole on the surface layer of fiber, increases the specific surface area of PPS fiber；Then the PPS fabric after corona treatment is passed through into sulfonation working process again, the number for connecting hydrophilic radical can be increased in this way, so that the hydrophilic effect of PPS fabric is more preferable.
In order to make PPS fabric obtained that there is better hydrophilic effect, it is preferred that PPS yarn obtained in step (1) is processed by least one of plasma process, sulfonation processing, graft copolymerization processing method, hydrophilic polyphenylene sulfide yams are made.Due to single plasma process, it is understood that there may be durability is poor, and fabric can hydrophilicity decline after concise.The mode of graft copolymerization during post-processing, because medicament and high temperature influence caused by hydrophilicity decline, so more preferably PPS yarn is processed by sulfonation, or more preferable PPS yarn is after plasma process, then carries out sulfonation processing.
The method of sulfonation processing is that yarn is handled 1~5min through excess temperature for 80~120 DEG C of sulfonation treatment fluids (85~98% chlorosulfonic acids or the concentrated sulfuric acid), connects hydrophilic radical sulfate radical etc. on the surface layer of PPS fiber.Plasma processing method can choose atmospheric plasma processing or vacuum plasma processing, its surface is set to form concave-convex pitting, increase the capillary effect and water imbibition of PPS fiber, hydrophilic radical sulfate radical, carboxylate radical, carbonate, hydroxyl, carbonyl etc. are connected on the surface layer of PPS fiber simultaneously, the effect of these hydrophilic radicals connected can increase the absorption speed of PPS fiber, can also improve the purity of hydrogen, oxygen.
By following embodiment, the invention will be further described.But protection scope of the present invention is not limited to these examples.
