Printing and dyeing are with active ink and adopt this ink to carry out the method for jet printing on denim fabric
Technical field
The present invention relates to technical field of textile printing, be specifically related to a kind of printing and dyeing with active ink and adopt this ink to carry out the method for jet printing on denim fabric.
Background technology
Cowboy's industry development prospect is very wide, and focus development tencel and functional jean can further satisfy the demand that jeans develop at present.Though current enterprise competitiveness constantly strengthens, domestic jean is still based on low-and-medium-grade products, and high-grade jean proportion is not high, and traditional jean can not satisfy the needs in market.Greatly developing high value added product is the key issue that present jean and clothes production enterprise face.
The innovation of back finishing technique and utilization have become the necessary means that improves product quality and added value.The jean facework is put in order by dyeing and printing technology, can obtain good effect and the aesthetic effect taken.Traditional clothing fabric with art pattern mainly is by multiple printing and dyeing processing technology, makes different dyestuffs by flower version painted formation pattern on the fiber of lining.In addition, also have the method for passing through other chemical processes or passing through digital spray printing, hot transfer printing to form the clothing fabric design.
Ink-jet printed is that the image that will handle by digitizing technique is input to computer, after the layout of computer stamp colour splitting system, control ink-jet printed system by special software (RIP) again, with the direct spray printing of special-purpose ink to various textiless, thereby form the PRINTED FABRIC of design requirements.Ink-jet printedly compare traditional printing technology following advantage is arranged: (1) does not have a version stamp.The computer coloured image can directly show on the fabric, can save operations such as traditional printing stencil, saves operationlocation.(2) save the labour.Compare with traditional printing machine, ink-jet printed usefulness be bantam.Movably mechanical part has only head section and fabric to transport part, and their mechanism is all fairly simple.(3) print quality top grade.Ink-jet printed rich color, transition are level and smooth naturally, do not have the restriction of cover chromatic number, can print the level smoothness, have the decorative pattern of photograph style, can reflect the complexity and the fineness of pattern realistically.(4) form by limited primitive colour.Need not make a plate, only need four primitive colour dye inks of CMYK, just can obtain required color.(5) repeatable production.But the whole pattern data of CAD system prolonged preservation can repeat when needing to call.(6) can be satisfying personalized, small serial production and fast-developing needs.(7) change batch efficient height.Only needing the numerical information of new pattern is delivered to ink-jet decorating machine is interchangeable batch.(8) help environmental protection.Dyestuff be need based jet on matrix, be anhydrous arrangement, reduced the waste of chemical preparations and the discharging of waste water, and the noise during ink-jet is low relatively, these all can reduce the injury to human body.
Employed printing ink is generally the polymerizability ink-jet dye on the domestic market at present, and it is most of from import, also there are a lot of problems in the price height of printing ink at aspects such as color depth, washing fastnesses, and this also is the at present ink-jet printed universal major cause that do not have.
Summary of the invention
The object of the present invention is to provide a kind of polymer, nontoxic, safe printing and dyeing active ink, and adopt the very environmental protection of this active ink, the method for energy-conservation, jet printing on denim fabric that stability is good.
The object of the present invention is achieved like this: a kind of printing and dyeing active ink is characterized in that: described printing and dyeing comprise with the polymer active ink: vinyl sulfone epoxy resin-matrix macromolecule reactive dye 5-20%; Tensio-active agent OP-10 0.5-1%; Wetting Agent for Printing Inks PEG 5-10%; Deionized water 69-89.5%, after preparing by above-mentioned prescription, by add the pH value damping fluid make printing and dyeing with the pH value of polymer active ink between 7-9.
A kind of method that adopts the described printing and dyeing of claim 1 to carry out jet printing on denim fabric with active ink, it is characterized in that: at first jean is carried out pretreatment process, and oven dry, adopt printing and dyeing to carry out ink-jet printed then with the polymer active ink, carry out postprocessing working procedures and oven dry again, carry out washing step and oven dry at last.
Described pretreatment process carries out enzyme desizing and anti-imbibition processing for jean is immersed in the solution, its solution formula is to add in every premium on currency: amylase 2-10g, salt 5-15g, sodium alginate 1-5g, sodium bicarbonate 2-10g, urea 1.5-7.5g, after preparing by above-mentioned prescription, to make the pH value of solution be 5-7 by adding the pH value damping fluid; Treatment condition: temperature is 45-70 ℃.
Described aftertreatment technology is to add alkali 10-20g in every premium on currency for spray thermokalite technology, the concentration of alkali, and temperature is 60-90 ℃.
The bake out temperature of described technological process is controlled at 60-120 ℃.
The composition of described jean can be to contain cotton fibre, polyster fibre, regenerated cellulose fibre, silk.
Positively effect of the present invention is: the printing and dyeing active ink that adopts the vinyl sulfone epoxy resin-matrix macromolecule reactive dye preparation, it has following characteristics: (1) combines with high molecular owing to organic dye molecule, the migration of dye molecule and permeate less, can improve shortcoming, the especially azoic dyestuff of the easy migration of general small molecules dyestuff and the resistance to migration of anthraquinone dye significantly improves greatly; (2) have water-solublely, can be directly used in the textile ink-jet stamp, realize anhydrous artistic finishing; (3) molecular weight is big, can not be seen through by cytolemma, can be by bacterium, microbiological degradation, thus do not absorbed by organism, harmless to organism; (4) have high melt point, thermotolerance improves greatly.Therefore (5) because high molecular dye is the dyeing of molecular level, compare with the small molecules dyestuff, consumption greatly reduces, show bright-colored, colourity jail, dye utilization rate advantages of higher; (6) general dissolving seldom or is not fully dissolved in solvent, and fugitive color has not contained chromophoric group owing in the macromole, and it becomes the structure colored materials, thereby shows good washing fastness in cowboy's wash water.
This polymeric dye belongs to functional polymer, and is nontoxic, and safety meets the direction of the development of materialogy from now on, also meets the aim of green colouring material chemical developer simultaneously.With it ink-jet printed arrangement that is applied to cowboy's fabric, reduced not only that dyeing waste-water is administered and to the load of environment, and reduced production process, saved the production time and make production cost reduce greatly.
