Description
Technical field
The spray foam colouring method that the present invention relates to use REACTIVE DYES, belongs to dope dyeing technical field.
Background technology
In the dyeing course of textiles, REACTIVE DYES is current to one of most important dyestuff of cellulose dyeing, and pad dyeing is one of important process of reactive dyeing.But the pad dyeing dyeing course of REACTIVE DYES need to consume a large amount of water and chemicals at present, and final discharge has brought immense pressure to environmental protection.The current improvement that dyeing, dyestuff are carried out is all the service efficiency in order to improve dyestuff, reduces disposal of pollutants, saves the energy, reduces the consumption of chemicals.
Tradition REACTIVE DYES continuous knot dyeing conventional process comprise pad dye liquor-dry-pad chemical liquids-decatize-washing, cold rolling-to pile-to wash, roll-dry-roast-wash, roll-steam-wash, roll-short steaming-techniques such as washing wet.Above technique is at patent WO/2009/099420, and US2006/0260073 A1, has relevant introduction in US5885305.In textile dyeing production process in the past, use the continuous dyeing method of REACTIVE DYES substantially to adopt above method to the woven of cellulose fibre.But above method all exists various problems, need to improve at everyways such as reducing dye dosage, the saving energy, minimizing disposal of pollutants, operation convenience.
The technique of the most often applying take traditional continuous dyeing is as example, as shown in Figure 1, for padding dye liquor-dry-pad chemical liquids-decatize-washing process schematic diagram, the color depth that fabric 42 is dying as required carries out the immersion liquid of staining solution in dyestuff squeeze device 1, then use the first padding machine 2 to roll and (comprise the REACTIVE DYES of the variable concentrations adding according to the dye level of difference needs except unnecessary staining solution, may add bleeding agent according to the characteristic of fabric and dyestuff, migration inhibitor, the auxiliary addition agents such as anti-reducing agent).Use the modes such as infrared baking unit 3, baking oven 4 or other mode that can be used for drying to dry fabric at baking stage.In chemical liquids squeeze device 5, carry out fixation solution 6(and comprise the bright mixed solution powder of caustic soda, soda ash and salt or unit of different proportionings) immersion liquid.By the second padding machine 7, fixation solution 6 is applied on fabric 42, generally the liquid carrying rate by fabric after the process of padding 42 (on fabric with staining solution and the gross weight of fixation solution and the ratio of fabric weight) is 60%-120%.Steaming device 8 is in the environment of saturated vapor, makes REACTIVE DYES and cellulose fibre carry out fixation and react under the effect of alkali lye.Water washing device 9 is that the loose colour that the REACTIVE DYES of not fixation or hydrolysis is formed cleans.In above dyeing course, in the time padding the chemical liquids stage, use a large amount of salt or glauber salt to urge to dye to dyestuff, prevent that dyestuff from dropping in chemical liquids 6 in a large number.Fabric 42 is padding after chemical liquids or to enter liquid carrying rate before steam box larger, be generally 60-120%, a large amount of humidity that fabric 42 is brought into after padding makes in next procedure decatize phase process the temperature and humidity balance in steaming box be difficult to control, and consumes a large amount of steam or the energy guarantees stable decatize state.And in this process, owing to having used in a large number salt, chlorion is wherein comparatively serious to the damage of stainless steel equipment, reduce the service life of steam box He Hou road stainless steel equipment.A large amount of uses of salt or glauber salt are for padding in chemical liquids phase process, to REACTIVE DYES rise short dye used, but in the washing stage on fabric 42 with a large amount of salt or glauber salt simultaneously also the loose colour dyestuff after hydrolysis is had to the short effect of dying, reduce greatly the cleaning efficiency of loose colour, in water-washing process, need to use a large amount of water and soaping agent, thereby cause unnecessary wastes and pollution discharge.The most important thing is due to generally in this chemical liquids 6, the concentration of salt is 200 grams per liter left and right, and all salt will all discharge with sewage, and the salt of discharge is difficult to process in sewage, cause environmental pollution, the pollution of salt is also the most reluctant polluter of printing and dyeing enterprise.
In order to solve the consumption of the energy, water, salt and other chemicals a large amount of in REACTIVE DYES continuous dyeing process, dyer author has developed cold rolling-heap-washing process, as shown in Figure 2, for cold rolling-heap-washing process schematic diagram, use proportioning pump 12 that dye solution 10 and alkali lye 11 are added in padding liquor tank 13, fabric 42 first immerses padding liquor tank 13, by padding machine 14, unnecessary alkali lye and REACTIVE DYES liquid are shut out from fabric, by cold dome device 15, carry out reactive dye color fixing through 20-48 hour bank up, after cold dome, fabric is removed loose colour through washing unit 16 again.Although this technique has lowered the consumption of the energy greatly, lower the consumption of salt or glauber salt, but there is the shortcoming that is difficult for consistent and variation of ambient temperature and causes every volume lots processed aberration due to clot padding machine pressure in batches, also there is the defect poor to the spreadability of dead cotton and immature cotton in this technique.And the dyeing time of this technique is longer, production scene can not be corrected coloured light and check fabric quality in time, once occur that quality problems are difficult to revise, and be that property is difficult to revise by the gross.
In traditional dyeing process, some REACTIVE DYES is used rolls-dries-roasting-washing process, as shown in Figure 3, for rolling-dry-roast-washing process schematic diagram, the dye liquor that fabric 42 comprises REACTIVE DYES and alkaline agent by dye liquor alkali lye squeeze device 17() after drying unit 18, carry out fixation through baking device 19 again, then remove loose colour through washing unit 20.Although this technique flow process shortens, in the process of padding, alkali lye and REACTIVE DYES are with bathing, and long time running can make dyestuff hydrolysis cause loose colour to increase, and need to add a large amount of urea to guarantee in the certain humidity baking under condition.This technique is not suitable for the dyeing of regenerated celulose fibre and heavily fabric, easily yellowing after textile dyeing, and it is poor that light and chlorine float fastness, is not suitable for dying bright-colored.
Some dyeing adopts roll-steaming-washing process, as shown in Figure 4, for rolling-steam-washing process schematic diagram, fabric 42 pads the dye liquor of REACTIVE DYES and alkaline agent by dye liquor alkali lye squeeze device 21() after directly in steaming device 22, carry out saturated vapor decatize, and then through washing unit 23 remove loose colour.Although this technique flow process shortens, in the process of padding, alkali lye and REACTIVE DYES are with bathing, and long time running can make dyestuff hydrolysis cause loose colour to increase.And fabric 42 liquid carrying rates are larger after the process of padding, liquid carrying rate, generally all at 60-120%, also can cause decatize condition wayward.This technique fixation rate variance, is not suitable for processing dark product, and the vividness of color is also not ideal enough.
Recently some researchers roll-wet short steaming-washing process in research reactive dyeing, as shown in Figure 5, for rolling-wet short steaming-washing process schematic diagram, fabric 42 pads the dye liquor of REACTIVE DYES and alkaline agent by dye liquor alkali lye squeeze device 24() after, under the condition of low humidity, enter successively in the first baking device 26 and the second baking device 27 and bake (humidity 20-35%, temperature 120-140 ℃, 30-120s, steam injects from bottom inlet 29) fixation, through washing unit, loose colour is removed in 28 washings.Although this technological process is shortened, Color is better, but be applied to liquid carrying rate on fabric 42 generally all at 60-120% by the process of padding in the process of padding dye liquor and alkali lye, under the condition of this liquid carrying rate, control the condition that bakes (the humidity 20-35% of follow-up low humidity, temperature 120-140 ℃) relatively waste energy, the control of temperature and humidity is also relatively difficult, especially in the time of the thickness difference of fabric, can cause the fluctuation of the humidity and temperature of bringing baking device into, need complicated equipment to carry out accurate humidity and temperature control and abundant operating experience.Owing to passing through this mode, low humidity bakes the more difficult control of degree of stability of condition, so this technique has strict restriction to the variety adoption of REACTIVE DYES, and needs the temperature and humidity in casing to carry out strict detection and control, and equipment investment is larger.
