Detailed description of the invention
Be clearly and completely described the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
Below the colouring method of the superhigh molecular weight polyethylene fibers that the embodiment of the present invention provides is described in detail.
A colouring method for superhigh molecular weight polyethylene fibers, comprises the steps: that buffer solution dipping bath put into by the pine of the ultra-high molecular weight polyethylene after by purified treatment formula cylinder yarn, and starts to heat up; When temperature reaches 50 ~ 60 DEG C, add the dye dispersion liquid stirred, namely enter dyeing phase; When temperature reaches 70 DEG C, keep this temperature level dyeing at least 5 minutes, then continue to be warming up to 85 DEG C; After temperature reaches 85 DEG C, continue to be warming up to 110 DEG C with the speed being no more than 1.5 DEG C/min; After temperature reaches 110 DEG C, continue to be warming up to 133 DEG C with the speed of 2 DEG C/min at the most; After temperature reaches 133 DEG C, keep this temperature level dyeing at least 30 minutes, namely complete dyeing phase; The superhigh molecular weight polyethylene fibers completing dyeing phase, successively after reduction cleaning and drying and processing, namely obtains the dyeing superhigh molecular weight polyethylene fibers of finished product.
Wherein, described buffer solution can adopt the buffer solution by high temperature dispersant and Acetic acid-sodium acetate solution composition in prior art, and its concrete component proportion with reference to prior art, can repeat no more in present specification.In the process of the ultra-high molecular weight polyethylene pine formula cylinder yarn dipping bath in buffer solution after purified treatment, should make it to soak into air that is even and that get rid of in product dyed thereby, this can strengthen dye effect in subsequent treatment and COLOR FASTNESS.When entering dyeing phase, bath raio is preferably 1:20 ~ 1:40, is preferably 1:30.
Particularly, this colouring method can comprise following specific embodiments:
(1) spool of ultra-high molecular weight polyethylene pine formula cylinder yarn can adopt stainless steel spring pipe or the high temperature resistant and plastic tube of acid and alkali-resistance, first-selectedly uses stainless steel spring pipe, but in actual applications, dry because the embodiment of the present invention needs to carry out low temperature (not higher than 70 DEG C) to the superhigh molecular weight polyethylene fibers completing dyeing phase, and carry out low temperature drying in prior art and usually can use low temperature hf drying equipment, stainless steel spring pipe can become conductor and damage low temperature hf drying equipment in low temperature hf drying equipment running process, therefore the low temperature drying process of the embodiment of the present invention is if adopt low temperature hf drying equipment to implement, so the spool of ultra-high molecular weight polyethylene pine formula cylinder yarn preferably adopts the high temperature resistant and plastic tube of acid and alkali-resistance.Meanwhile, the spool of ultra-high molecular weight polyethylene pine formula cylinder yarn preferably adopts cylindrical bobbin, and it not only has good sealing, and flow runs off less, dye liquor flows to evenly, layer is poor and cylinder has differed from control.In addition, the yarn of ultra-high molecular weight polyethylene pine formula cylinder yarn can be simple superhigh molecular weight polyethylene fibers, also can be through adding the ultra-high molecular weight polyethylene low-stretch yarn be twisted into.
(2) profile of ultra-high molecular weight polyethylene pine formula cylinder yarn is Pagoda-shaped, and its corner is circular arc; The base diameter of each ultra-high molecular weight polyethylene pine formula cylinder yarn is that 10 ~ 18cm is (preferably between 13 ~ 15cm, be preferably 15cm), and the gross mass of each ultra-high molecular weight polyethylene pine formula cylinder yarn is 400 ~ 1000g (preferably between 850 ~ 950g, being preferably 900g); If base diameter is excessive or gross mass is excessive, be then unfavorable for that dye liquor circulates, reduce dyeing quality, and base diameter be too small or gross mass is too small, although dye liquor can not be hindered to circulate, can reduce the effective rate of utilization of resource.Meanwhile, the thread density of ultra-high molecular weight polyethylene pine formula cylinder yarn is preferably 0.33 ~ 0.40g/cm
3; If thread density is too large, then reel for yarn difficultly penetrates very thick layer around too tight, dye liquor, yarn local can obtain colour cast very little shallow because of contact dyestuff, thus look flower or chromosphere etc. can be caused to contaminate defect; If thread density is too little, then reel for yarn is easily out of shape comes off around too pine, cylinder yarn, may occur ravellings, be difficult to the phenomenons such as machine.In addition, because yarn is around cylinder tension force, around the larger position of cylinder density, the penetration speed of the dye liquor amount of penetrating that is slow, dye liquor is few, and yarn is around cylinder tension force, around the less position of cylinder density, the penetration speed of the dye liquor amount of penetrating that is fast, dye liquor is many, this can cause the dye level of yarn inconsistent, and therefore in actual production, yarn is wanted evenly around cylinder tension force, also want even around cylinder density; Due to UHMWPE have that rigidity is large, poor, the degree of crystallinity high of coherent between yarn, therefore gauze can be wound around on spool around before cylinder, and the metal special processes of the prior art such as the such as little cylinder of large jacket casing can be adopted if desired, to ensure the consistent with around cylinder even density around cylinder tension force of ultrahigh molecular weight polyethylene yarn.
(3) because superhigh molecular weight polyethylene fibers needs to add the finishes such as lubricant, emulsifying agent, antistatic additive in the process being woven into yarn, if and these finishes are not removed before dyeing, so in dyeing course, these finishes can form one deck " blocking film " in yam surface, dyestuff is hindered evenly to spread to fibrous inside, permeate, thus not only easily cause colouring irregular, produce the dye defects such as look flower, color spot, and significantly can reduce the COLOR FASTNESS of the rear yarn of dyeing; Therefore need first to carry out purified treatment, to remove finish before to ultra-high molecular weight polyethylene pine formula cheese yarn dyeing.
The preparation process of the ultra-high molecular weight polyethylene pine formula cylinder yarn after purified treatment can comprise: the sodium hydroxide solution or the diisopropyl ketone solution that ultra-high molecular weight polyethylene pine formula cylinder yarn are placed in 1.0g/L, and under 50 ~ 90 DEG C (preferably 80 DEG C) dipping bath at least 20 minutes, again after washing and acid-base neutralization process, be namely purified the pine of the ultra-high molecular weight polyethylene after process formula cylinder yarn.In actual applications, ultra-high molecular weight polyethylene pine formula cylinder yarn is preferably placed in the diisopropyl ketone solution of 1.0g/L, and is placed in compared with sodium hydroxide solution, and the COLOR FASTNESS of the dyeing superhigh molecular weight polyethylene fibers that the former is finally obtained is far above the latter.
(4) dye dispersion liquid can adopt the DISPERSE DYES bought by commercial means in prior art to make, also can be formed by multiple DISPERSE DYES mixed preparing, but the use amount of DISPERSE DYES preferably accounts for 3% ~ 5% of superhigh molecular weight polyethylene fibers gross mass to be dyed.Because the cost of DISPERSE DYES is lower, the dyeing that therefore embodiment of the present invention provides has lower being produced into.
(5) in dyeing phase, dyeing temperature directly can have influence on the expanded speed of superhigh molecular weight polyethylene fibers and the colouring speed of DISPERSE DYES, therefore in embodiments of the present invention, preferably, the depth of dyeing, the recurrent state of dye liquor and different dyeing phase fine or not according to the level-dyeing property of used DISPERSE DYES carry out reasonable set to the heating rate of dyeing phase; In a particular embodiment of the present invention, when dyeing temperature is below 85 DEG C, the seldom upper dye of dyestuff, therefore this temperature province can directly heat up; When dyeing temperature is between 85 DEG C ~ 110 DEG C, dyeing speed increase is the fastest, therefore preferably strictly controls programming rate in this temperature province at 1.5 DEG C/below min, to improve Color and COLOR FASTNESS; When dyeing temperature is between 110 DEG C ~ 133 DEG C, dyeing speed slows down gradually, therefore the heating rate in this temperature province can be put soon a little, preferably the heating rate of this temperature province is controlled at 2 DEG C/min, so both can ensure that this dyeing processing technique had processing speed faster, can ensure again that final obtained finished product dyeing superhigh molecular weight polyethylene fibers had good Color and COLOR FASTNESS.
(6) in dyeing phase, when temperature reaches 70 DEG C, this temperature level dyeing at least 5 minutes should be kept, in a particular embodiment of the present invention, the time of proper extension this section of insulation level dyeing, dyeing quality and the COLOR FASTNESS of the dyeing superhigh molecular weight polyethylene fibers be finally processed into can be strengthened, but this can extend the time of whole dyeing processing technique relatively, therefore, under the prerequisite taking into account dyeing quality and dyeing kinetics, specific embodiments of the invention preferably keep this temperature level dyeing 10 minutes when temperature reaches 70 DEG C.
(7) in dyeing phase, after temperature reaches 133 DEG C, this temperature level dyeing at least 30 minutes should be kept; Because DISPERSE DYES is by hydrogen bond and Van der Waals force contaminate superhigh molecular weight polyethylene fibers, good migration property can be had under the hot conditions of 133 DEG C, therefore the time of proper extension this section of insulation level dyeing can correct the suction look inhomogeneities that produces of temperature rise period by moving dye effect, realize an even change of color and luster, this has a significant effect to the darker color and luster of dye.
(8) in dyeing phase, the mixed liquor that buffer solution and dye dispersion liquid form circulates between the inner and outer of ultra-high molecular weight polyethylene pine formula cylinder yarn, and the time penetrated by Inside To Outside is greater than by the time penetrated inside lateral; This can ensure and there will not be aberration inside and outside ultra-high molecular weight polyethylene pine formula cylinder yarn.In actual applications, the mixed liquor that buffer solution and dye dispersion liquid form cycles through circulating pump and realizes between the inner and outer of ultra-high molecular weight polyethylene pine formula cylinder yarn, and the flow of circulating pump is 25 ~ 60L/kgmin, the pressure of circulating pump is 10 ~ 20m pressure head water column, this can make dye liquor have comparatively large discharge and pressure, contribute to dye liquor to penetrate layer and realize level dyeing, strengthen COLOR FASTNESS.
(9) because ultra-high molecular weight polyethylene pine formula cylinder yarn is after carrying out above-mentioned penetrability dyeing, its surface can with loose colour to a certain degree, these loose colours not only can reduce dyefastness and bright in color light degree, but also easily cause uneven shade, therefore the superhigh molecular weight polyethylene fibers completing dyeing phase is preferably first cooled to lower than 80 DEG C, carry out reduction cleaning again, to remove the loose colour on surface, and can make the color development of dyeing superhigh molecular weight polyethylene fibers gorgeous bright, color and luster is uniform, rub resistance, COLOR FASTNESS can improve 0.5 ~ 1 grade; In actual applications, the rate of temperature fall completing the superhigh molecular weight polyethylene fibers of dyeing phase can be 1-2 DEG C/min, but preferably complete the starting stage rate of temperature fall of dyeing phase suitably slow (such as: 1-2 DEG C/min), when temperature drops to 110 DEG C can fast cooling (such as: 5 DEG C/min) to lower than 80 DEG C, this can avoid causing cockline or feel coarse.
Reduction cleaning preferably adopts following method: the NaOH solution of 1.5 ~ 6.5g/L mixed with the ratio of the sodium hydrosulfite of 0.5 ~ 2g/L according to weight ratio 1:1-1:3, and to dyeing superhigh molecular weight polyethylene fibers reduction cleaning 20 minutes at 80 DEG C, then clean with clear water, again after acid-base neutralization, namely complete reduction cleaning.Certainly, reduction cleaning also can adopt process for reductive post-cleaning commonly known in the art, but the quality of obtained finished product superhigh molecular weight polyethylene fibers and COLOR FASTNESS are lower than above-mentioned process for reductive post-cleaning.
(10) because hyperthermia drying not only can reduce production efficiency, and easily cause the distortion of loose formula cylinder yarn, therefore the superhigh molecular weight polyethylene fibers of dyeing phase is completed after reduction cleaning, preferably dry with the bake out temperature being no more than 70 DEG C, until moisture is lower than 5%, namely obtain the dyeing superhigh molecular weight polyethylene fibers of finished product.In actual applications, this low temperature drying process can adopt low temperature hf drying equipment, bake out temperature can be 60 DEG C, dry about 30min, the moisture of dyeing superhigh molecular weight polyethylene fibers can be down to less than 5%, therefore not only there is higher production efficiency, and ensure that the quality of dyeing superhigh molecular weight polyethylene fibers of finished product, the phenomenons such as loose formula cylinder yarn distortion can not occur.
Further, the intensity >=25cN/dtex of the finished product dyeing superhigh molecular weight polyethylene fibers that the colouring method of the superhigh molecular weight polyethylene fibers that the embodiment of the present invention provides finally obtains, modulus >=1000cN/dtex, elongation at break >=3%; Adopt GB/T5713-1997 to carry out the water-fastness COLOR FASTNESS of fiber to this finished product dyeing superhigh molecular weight polyethylene fibers to measure, its variable color is 4-5, and staining is 3-4; GB/T3920-2008 is adopted to measure this finished product dyeing superhigh molecular weight polyethylene fibers: fiber dry friction COLOR FASTNESS is 3-5, and wet friction COLOR FASTNESS is 3-4.
As can be seen from technique scheme, the embodiment of the present invention not only production technology simple, repeatable strong, production cost is low, and process the COLOR FASTNESS of the product of producing high, can use for a long time.
