Abstract
The invention relates to a printing auxiliary agent in the spinning printing and dyeing industry and particularly relates to blending of a four-color-separation printing pretreatment solution for an active dye as well as a preparation method and an application method of the four-color-separation printing dye pretreatment solution. After being pretreated by the pretreatment solution, a textile can be subjected to printing work by using a four-color-separation printing process very well. Paste in the pretreatment solution is used for controlling the dispersion of the dye and also can be used as a paste material for loading a relatively large quantity of dyes; a surface tension conditioning agent is applied so that the dispersion of the dye can be controlled; and when the distribution of the dye on fibers is relatively uniform, the possibility of bonding the dye and the fibers is relatively high and the color fixation rate is relatively high. An alkaline agent is used so that the printed dyes are in an alkaline environment, active radicals of the printed dyes can relatively easily react with the fibers to form a covalent bond (bonding for short), and the active radicals are fixed on the fibers. Therefore, the dye does not contain the alkaline agent so that the dye can be prevented from hydrolysis when being stored. Urea is not required in a printing process so that the relatively environment-friendly effect is achieved.
Description
Technical field
The present invention relates to the printing assistant in textile printing and dyeing industry, specifically refer to a kind of pretreatment fluid being applicable to REACTIVE DYES four color separation stamp of modulation, fabric can apply the pattern flower pattern that four color separation printing technologies print cellulose fiber fabric better after this pretreatment fluid process.
Background technology
A kind of chromatography pattern that four color separation patterns adopt when being colored printings, utilize the three primary colors colour mixture principle of colorant, add black, amount to four kinds of blend of colors superpositions, formed so-called " full-color printing ", namely use cyan (Cyan), stamp that red (Magenta), yellow (yellow), black (Black) (being called for short CMYK) show all colours.Color theory all in natural visible spectrum can be obtained by CMY three color scheme system, but due to normally used dyestuff pure not, therefore often add black ink again to reach desirable reproduction.Thus four color separation stamps be based on three primary colors, black is skeleton, during printing, three primary colors version contrast is long, ten million kind of color is formed with three primary colors, can ensure bright in luster beautiful, black print is then minor skeleton, only play a part in the picture stable in, shadow color and profile, make image produce continuous tone change by CMYK tetra-look site at the double exposure of same position different directions, make flower pattern produce RGB effect.Relatively common Color Separate printing stencil making technology, four Color Separate printing stencil making technology have jumped out the limitation of a set of color half tone, thus the color tricks that stamp is produced is no longer by the restriction of machinery, can print out the product of photo level.But, because shades of colour is assorted by 4 dyestuffs, often runs into the problem of dye saturability during actual stamp, i.e. fabric the same area, too much dyestuff cannot be carried.Thus make rear road roller, particularly the 4th color version roller is printed and dyed and is expected easily to fade in water-washing process, the defect causing colour cast or there are differences with Original manuscript design.In addition, because four color separation stamps require high to version precision, therefore require high for the definition of pattern line in stamp process, this has good control with regard to needing to the diffusion of dyestuff on fabric.
Summary of the invention
For the problem current four color separation stamps contaminating saturability and dye diffusion control, the invention provides a kind of four color separation stamp pretreatment fluid and application processes thereof.
A first aspect of the present invention provides a kind of four color separation stamp pretreatment fluid formulas, and this kind four color separation thickening agent pretreatment fluid, is characterized in that, content is as follows by weight percentage for described four color separation thickening agent pretreatment fluid each components:
Thickener 5-12%;
Surface tension modifier 0.5-2%;
Alkaline agent 5-15%;
100% is adjusted to deionized water.
Preferably, thickener is sodium alginate or converted starch or carboxymethyl cellulose or is oxidized guar gum or allied colloid ALCOPRINT RTA.
Preferably, surface tension modifier is BYK333 or BYK401 or the DOW CORNING DC-57 of Bi Ke company.
Preferably, alkaline agent is potassium hydroxide, or NaOH, or potash, or sodium carbonate, or its composition.
A second aspect of the present invention provides the compound method of four color separation stamp pretreatment fluids, comprises the following steps:
Step one, adds thickener in deionized water;
Step 2, fully stirs 0.5-1.5 hour under 45-55 DEG C of condition;
Step 3, drops to room temperature, then adds alkaline agent and surface tension modifier respectively;
Step 4, continues to stir after 20-40 minute, obtains four color separation thickening agent pretreatment fluids.
Further, in step 2 under the condition of 50 DEG C, stir 1 hour.
Further, in step 4, mixing time is 30 minutes.
A third aspect of the present invention provides the technique for applying of described four color separation stamp pretreatment fluids, comprises the following steps:
Step one, fabric is through four color separation thickening agent pretreatment fluid process, and pick-up is 30-60%;
Step 2, carries out stamp by application of active dyestuff four color separation printing technique after treated fabric drying;
Step 3, after print, fabric is through 100-120 DEG C of decatize 3-8min;
Step 4, water-based sizing is finished product.
Further, after printing in step 3, fabric is through 110 DEG C of decatize 5min.
Beneficial effect of the present invention is, after REACTIVE DYES four color separation stamp pretreatment fluid of the present invention preliminary treatment, fabric can carry out stamp operation with four color separation printing technologies well.Thickener in pretreatment fluid not only controls the diffusion of dyestuff, and can carry more dyestuff as thickener, the application of surface tension modifier, the diffusion of dyestuff can be controlled, the distribution of dyestuff on fiber is more even, and the probability of dyestuff and fiber generation bonding is higher, and degree of fixation is higher.The use of alkaline agent, makes to print rear dyestuff in alkaline environment, its active group more easily and fiber react and form covalent bonds (abbreviation bonding), and to anchor on fiber.And so, without the need to containing alkaline agent in dyestuff, hydrolysis when can prevent dyestuff from storing.Without urea in stamp process, environmental protection more.
