Dye jigger of the present invention is described as follows: although there is inclination fabric roll shaft in prior art to realize the imagination of dye gigging engine dyeing gradient color, but there is following defect in this imagination: first because roll shaft needs to repeat to rotate forward-reversion in dyeing course, making fabric roll shaft and staining bath prevent producing angle between position causes fabric roll shaft that bent device need be adopted to be connected with motor, cause the unstable working condition of fabric roll shaft and the motor being often in rotary state, vibrations produce larger noise greatly, in the course of the work, and motor and Bendable device easily damage; Secondly because fabric roll shaft tilts, distance bottom the top distance staining bath of fabric roll shaft increases, the staining bath of existing dye jigger mostly is flat, as the dye liquor submergence fabric roll shaft in staining bath need injected in staining bath the dye liquor capacity much larger than conventional dye gigging, both added dyestuff consumption and too increased wastewater discharge.And gradient color also needs repeatedly to configure the dye liquor adding different colours when need change dye liquor concentration, multi-color gradual change; That is, in prior art, gradient color dye gigging technique compares the conventional dye gigging mode making fabric present the same depth, has larger wastewater discharge; Therefore the dye jigger design of existing use dye gigging engine dyeing gradient color needs larger economic input on flight-line maintenance cost and cost for wastewater treatment, and production cost is higher.Finally, existing design cannot be applied to the existing conventional dye jigger making fabric present the same depth, and need buy new dye gigging equipment separately as realized gradient color dyeing, and new dye gigging equipment urgent need wants the input of 1,000,000 yuan, production cost is higher.
Applicant by arranging cushion block, makes staining bath tilt together with fabric roll shaft in the design of dye jigger of the present invention; First obtained major technique effect is that staining bath tilts but the horizontal plane not run-off the straight under gravity of dye liquor in staining bath, the liquid level in fabric roll shaft and staining bath can be made to produce angle, fabric on roll shaft can be partially immersed in dye liquor, thus obtain on fabric width direction.The design of the staining bath secondly tilted, be equivalent to make dye liquor concentrate on the bottom end of staining bath, the staining bath of inclination compares the consumption that horizontally disposed staining bath can reduce dye liquor, thus reduces wastewater discharge.In last the present invention, to be placed with the design of cushion block convenient, flexible for support bottom end pad, directly can transform existing dye jigger, extract cushion block out and can make staining bath recovery level, carry out conventional dye gigging after terminating gradient color dyeing bottom support; Thus realize a tractor serves several purposes, enrich fabric product kind.
It is cylindricality that applicant designs mixer in the present invention, consider that the calculation method of physical volume of cylindricality is that floor space is multiplied by height, be convenient to be changed by the liquid level of dye liquor in mixer, weigh the volume entering dye liquor in staining bath, also can be used for calculating during gradient color dyeing once dye, secondary dyeing, three dyeing, four dyeing time staining bath in the change in concentration of dye liquor; Preferably, the horizontal direction cross section of described mixer is square, circular, can be convenient to calculate the dye liquor volume of preparing burden together.Preferably, the side bucket wall of described mixer is provided with the transparent windows of strip, and transparent windows subscript is marked with scale, and transparent windows adopts glass material, and transparent windows can be used in observing the change of the liquid level in mixer.
Applicant designs staining bath in the present invention and horizontal direction is inclined to 5 ° ~ 35 ° angles; Staining bath bottom surface is parallel with support bottom surface, is alternatively that support and horizontal direction are inclined to 5 ° ~ 35 ° angles.The effect of this angle design of applicant is: when staining bath and horizontal direction slanted angle are greater than 35 °, even if fill it up with dye liquor in the staining bath tilted, the fabric on fabric roll shaft also cannot completely by dye liquor submergence; When staining bath and horizontal direction slanted angle are less than 5 °, if narrow at the dyeing width in fabric width direction, the staining bath angle of inclination being then less than 5 ° can cause the dye liquor capacity in staining bath very few, goes up dye fabric (33 ~ 35 meters of long fabrics) not completely.Preferably, staining bath and horizontal direction are inclined to 15 ° ~ 30 ° angles, applicant finds that the design of 15 ° ~ 30 ° of angles can make the dye liquor submergence wide cut comparatively fast cotton fabric in staining bath after deliberation, and during 15 ° ~ 30 ° of angles, wide cut cotton fabric dye jigger works long hours in an inclined state and also can have higher stability.
Adopt the gradient color dye gigging description of the process of wide cut cotton fabric as follows for the present invention: applicant preferably arranges upper volume concrete operations and is: in staining bath 4, add water, the liquid level submergence fabric width of water, keep water temperature 60 ~ 70 DEG C, make fabric be immersed in the water 2 ~ 3 times; With effect of fitting between the fabric improving rolling, make fabric tightness is rolled up, cross tension force when the fabric after water contaminates and be also more convenient to control.Applicant by once dyeing, secondary dyeing, three dyeing, the mode of constantly adding dye liquor in four dyeing in staining bath dilute dye liquor in staining bath, be that in staining bath, dye liquor capacity increases, thus obtain pigmented section and constantly become large, the technique effect that the depth of dyeing constantly shoals.Because applicant is first to the liquid level A that the water that marked staining bath liquid level and correspondence marks in mixer, thus when determining upper dye gradient color, the cumulative volume of the dye liquor that can drop in staining bath.Once dyeing, secondary dyeing, three dyeing, four dyeing are the dye liquors adding 1/4 cumulative volume four times in staining bath, and adding dye liquor each time all has dye liquor to dilute to staining bath Central Plains; In final four dyeing, dye liquor remaining in mixer is disposed in staining bath, now in staining bath liquid level can reach water gauge note in mark liquid level step staining bath liquid level, namely meet the textile dyeing region of plan.In practical operation, because mixer adds in the process of dye liquor the dye liquor loss having trace in staining bath; When dye liquor remaining in mixer is disposed in staining bath by four dyeing, dye liquor liquid level in actual staining bath is by the staining bath liquid level 0.05 ~ 0.9mm a little less than water gauge note in staining bath, owing to there is effect of impregnation after water absorption of fabrics, pigmented section has slight change large, therefore 0.05 ~ 1mm has no significant effect the pigmented section that final fabric obtains, negligible.
In configuration dye liquor step, in the rear mixer of configuration, the liquid level of dye liquor need reach the liquid level A that 1/2 water marks in mixer, first be convenient to calculate the dye liquor capacity added in staining bath, ensure that the dye liquor added in once dyeing has good concentration, when can make once to dye, fabric obtains denseer color.Preferably, the method for described configuration dye liquor is REACTIVE DYES 0.5 ~ 3owf%, glauber salt 30g/L, ground caustic 5g/L and water are mixed; Adopt the present invention's maintenance dyeing temperature 65 ~ 75 DEG C used to dye, make fabric immerse 2 ~ 3 times in dye liquor, the fabric of COLOR FASTNESS excellent effect can be obtained.Once dye: the dye liquor of the liquid level A marked in mixer by 1/4 water in mixer is disposed in staining bath, and now in staining bath, dye liquor concentration is the highest, dye liquor concentrates on the staining bath bottom tilted, and contaminates the darkest pigmented section of color on fabric width direction.Applicant requires in the dye gigging technique of gradient color of the present invention, once dyes, secondary dyes, three dyeing all adopts and makes fabric immerse 2 ~ 3 times in dye liquor, is the dye-uptake in order to improve fabric.And applicant requires to make fabric immerse in dye liquor 4 ~ 5 times in four dyeing, first be because during four dyeing, minimum the contaminated color of dye liquor concentration is the most shallow, the immersion of 4 ~ 5 times can improve the dye-uptake of fabric to light color, is secondly that the circulation of 4 ~ 5 times can so that equilibrium be once dyeed, secondary dyes, the Color of three dyeing; Particularly to the edge of first three pigmented section, the dye liquor concentration of four dyeing is minimum, fabric adopts the circulation of 4 ~ 5 times to immerse, and can play slight dilution to the Color of the edge of first three pigmented section, avoids the edge of pigmented section to produce significantly banded segmentation.Fabric is repeatedly immersed in dye liquor, is the staining method that dye jigger is conventional, and fabric can repeat the process immersing dye liquor-disengaging dye liquor under the drive of fabric roll shaft.In secondary dyeing, in mixer, add water, the liquid level A making liquid level in mixer return to 1/2 water to mark in mixer, effect is diluted staining solution; The dye liquor of the liquid level A marked in mixer by 1/4 water in mixer is disposed in staining bath, makes the secondary dye liquor used that dyes compare the dye liquor used that once dyes and dilute to some extent.
Applicant finds under study for action: in technique of the present invention, employing point adds dye liquor, four dyeing for four times in staining bath, and the dye liquor in staining bath is constantly diluted, thus makes the pigmented section of fabric obtain natural fade effect from shallow to deep.When the number of times adding dye liquor in staining bath is less than four times, the change in concentration that in staining bath, dye liquor dyes at every turn is excessive, and the fade effect of pigmented section not nature on the fabric obtained, has significantly banded sense.When the number of times adding dye liquor in staining bath is more than four times, although the number of times adding the dye liquor diluted in theory in staining bath divide more, on fabric, the fade effect of pigmented section is excessively more natural.But applicant finds that too much gradation adds dye liquor and there is following defect under study for action: be first that number of times owing to adding dye liquor in staining bath is too much, the too much dilution number of times of dye liquor in staining bath, cause the increased frequency dyeed, gradient color dye gigging technique total used time is long, textile dyeing efficiency is declined, loses the market competitiveness; Secondly, when the number of times adding dye liquor in staining bath is more than four times, dyestuff when both cannot ensure to add for the last time dye liquor in staining bath in batching is finally all transferred in staining bath, also cannot ensure simultaneously last when adding dye liquor in staining bath dye liquor liquid level can reach the staining bath liquid level marked in markers step of the present invention; More than cannot ensure, cause the addition of dyestuff in the number of times adding dye liquor in staining bath is more than mixer when four times to be difficult to determine, the pigmented section area on fabric is difficult to determine.Applicant considers that the maximum fabric width of existing wide cut cotton fabric is 3 meters ~ 4 meters, the mode adding dye liquor for four times of the present invention, existing wide cut cotton fabric can be made fully to obtain good gradual change Color, and ensure that the dyestuff added in batching is finally all transferred in staining bath, be convenient to calculate in blending process the addition of dyestuff and the pigmented section of fabric in mixer, and the liquid level A that the liquid level A that in the present invention, 1/2 water marks in mixer, 1/4 water mark in mixer, the mode adding dye liquor for four times calculate easy, are convenient to operative.
