Description
Technical field:
The present invention relates to a kind of processing denim control panel, particularly relate to a kind of control panel of handling dyeing pure cotton jeans.
Background technology:
The clothes that indigo dyeing or special dark indigo dyeing denim are made can obtain the rich and gaudy bright special effect of color and luster after wearing away processing, " super indigo " dyeing cowboy is furnished with two big features: promptly dye level is especially deeply with to wear away COLOR FASTNESS good especially.The conventional denim warp thread indigo dyeing degree of depth all 1%～amount of the bipseudoindoxyl dye that dyes is many especially, " super indigo " dye level then needs to reach more than 4%, " super indigo " dyeing jean need stand to repeat to wear away more than 3 hours, its color and luster still can meet or exceed the depth of color of normal dyeing denim when wearing away, and its coloured light should be rich and gaudy much brighter than the normal dyeing denim.For the COLOR FASTNESS of wearing away of indigo dyeing denim, its essence is and depend on the saturating core degree of dyestuff yarn, but not dyestuff itself wear away fastness (indigo wet-milling fastness only is 1 grade), promptly saturating core degree is worn away COLOR FASTNESS better better.And also be very important for its painted fastness of conventional denim, traditional dyeing is difficult to guarantee above-mentioned requirements, studying new dyeing is the task of top priority of dyeing and finishing industry,
Past so-called " the quick washing process of indigo dyeing ", be actually in the yarn dyeing process, deliberately make bipseudoindoxyl dye very shallow to the saturating core degree of fiber, wear away when jeans like this and add man-hour, after yam surface one deck dyestuff is as thin as a wafer ground off, expose more white yarn core, make color and luster very fast thin out, thereby reach after the short time wears away the effect of fading immediately.And " super indigo " dyeing in contrast, requires the saturating core degree of dyestuff good especially, just can make jeans after wearing away processing, obtains not only dark dense but also gorgeous bright color and luster.
Because the concentration of " super indigo " dyeing cowboy dyestuff reaches 3～4g/L, the dye liquor viscosity increases like this, mobile variation, influence the penetrating power of leuco dye, the COLOR FASTNESS of wearing away of denim is reduced, traditional method is to take to increase once more the design of dye level, the indigo concentration of dye liquor is increased once more, it is poorer that permeance property also just becomes, and so comes and goes to form vicious circle, the requirement that does not still reach " super indigo " look.Solve this difficult problem with the method that increases dyeing road number.Dyeing road number is increased to 8 roads, even 10 roads, investment cost, dying material being consumed increase, operation easier increases, and has increased the pollution to environment.

When adding higher but not reaching the voltage of puncture at electrode roller 1,2 two ends, if near the electric field the electrode is very strong, then near the gas medium the electrode is by partial breakdown and electrogenesis corona phenomenon, corona treatment techniques is that material surface is carried out the new technology that modification is handled, corona treatment adopts the SDCD16-2-10 corona discharge device that COTTON FABRIC is discharged, and processes voltage is respectively 6,8,10,12kV: corresponding every group of voltage of processing time is respectively 5,10,15,20s/3cm.
The COTTON FABRIC that is untreated fiber surface is comparatively level and smooth, has tangible bulge and uneven through fiber surface after the corona treatment, coarse groove structure. this is because the corona radiation produces high voltage electric field, airborne minority ion or free electron are accelerated in high-voltage field and obtain higher-energy, other molecules when motion in the bump space, make the free ion of part molecular ionization Cheng Xin then, electronics, the free radical plasma, under high-voltage field, clashing into cotton fiber then, thereby fiber surface is produced corrasion. this coarse groove structure can increase fiber specific surface area.
After 10kV voltage, 10s/3cm speed corona treatment, a free radical that produces at fiber surface and an ion part are by fragmentation and isomerization a large amount of hydrophilic radicals that induce one, the content of various hydrophilic radicals is significantly increased, wherein-content of OH reaches maximum in the processing time during for 5S,-OH and-content of COOH etc. reaches maximum in processes voltage during for 10kV. in the high polymer infrared spectrum, have some bands of a spectrum, be called crystal zone and amorphous ribbon the aggregated structure sensitivity.Can be used to analyze the state of aggregation of high polymer and measure its degree of crystallinity.In cotton fiber spectrum, wave number be the 1437cm correspondence be the crystal zone, wave number be the 893cm correspondence be amorphous ribbon.Can infer the situation of change of fibre crystallinity by the content of corresponding wave number in the spectrum.Growth along with the processing time, the crest of 1437cm has certain increase, illustrates that degree of crystallinity has certain increase, but along with the increase degree of crystallinity increase in processing time is slower. along with the increase of processes voltage, degree of crystallinity also is that certain increase is arranged, and reaches maximum during for 10kV at voltage.
The radiation effects that corona treatment produces decomposes the hemicellulose in the cotton fiber. and the amorphous region is reduced, thereby improved the degree of crystallinity of fiber.But on the whole, the XRD figure of cotton fiber spectrum basically identical before and after the corona treatment. illustrate that corona treatment has certain influence to the cotton fiber crystal region, but influence is little, the high energy field intensity effect that corona treatment produces makes the crystalline region on cotton fiber surface and amorphous area content that variation take place, thereby the hygroscopicity of fiber is exerted an influence.
Different disposal voltage can also can produce different influences with the time to wetting property of the fabric.Corona treatment can obviously improve the wettability of COTTON FABRIC, without the COTTON FABRIC of corona treatment because the reason that surperficial cotton wax and other oily matters exist does not almost have wettability.After the corona treatment, the wettability of COTTON FABRIC then has clear improvement.Increase along with processes voltage, the suction head of COTTON FABRIC also increases thereupon, and along with the processing time increases, the suction head of COTTON FABRIC increases faint the reducing in back earlier, reach maximum in the time of behind certain hour, this mainly is because corona treatment has produced a large amount of free radicals on the cotton fiber surface.And introduced some polarity hydrophilic radicals, as-OH ,-C=O ,-COOH etc., the hygroscopicity of fiber surface is enhanced, water imbibition is also improved greatly.When the processing time increased to certain limit, the cotton fiber surface has produced some small-molecule substances and a weak interface layer is ridiculed, and made the hygroscopicity of cotton fiber be under some influence, but not obvious.
Different corona treatment voltage produces different influences with the time to the fabric adhesion property.Increase afterwards earlier along with the increase in processes voltage and processing time through the COTTON FABRIC of corona treatment and the adhesion between starch size and to reduce.This be on the one hand because along with processes voltage and the time increase of asking fiber surface crystalline region content increased and introduced-hydrophilic radicals such as OH, increased the active force that cotton fiber and slurry are asked; On the other hand, surpass certain model simultaneously when processes voltage and time, make the fiber surface molecular chain rupture, the formation small-molecule substance is removed, in addition, long-time radiation makes the cotton fiber surface produce particle, forms a weak interface layer, cause surface adhesion to descend, thereby the adhesion of COTTON FABRIC is descended to some extent.On the whole, the adhesion of asking through the COTTON FABRIC and the starch size of corona treatment has very significantly increases.
This specific embodiment can significantly improve superly dyes effect on indigo, and technical process is simple relatively, and low energy consumption, pollute little, the operational processes time short, COLOR FASTNESS effect evident characteristic.
