Description

A kind of stamp pre-treatment slurry and preparation method thereof

Technical field

The invention belongs to textile printing and dyeing field, particularly to a kind of stamp pre-treatment slurry and preparation method thereof.

Background technology

Ink-jet printed, have another name called digit printing, be the stamp carried out by digital technology.Ink-jet printed technology is as computer Technology development and gradually form a kind of integrate machinery, computer electronic information technology new and high technology produce Product, it comes across the mid-90 in 20th century the earliest, and the appearance of this technology is with the most perfect, to textile printing and dyeing industry Bring a completely new concept, the production principle of its advanced person and means, to textile printing and dyeing bring one unprecedented Opportunity to develop.

Ink-jet printed production process is briefly through various digitized means such as: scanning, digital photo, image Or computing mechanism deal with various digitized patterns input computer, then by computer color splitting printing system process after, by Special RIP software is by directly spraying various dedicated dyes (activity, dispersion, acid main coating) its sprayed printed system Print on various fabric or other medium, then after processing, various weaving face fabrics obtain required various height The Printing of precision, has the advantage of the following aspects compared with traditional dyeing and finishing technique:

The most ink-jet printed production process makes original process route be greatly shortened, and order speed is fast, draws a design cost significantly Reduce.

Break away from Conventional decal color separation in process of production due to the ink-jet printed technological process of production and retouch original text, film-making, net processed Process, thus the production time being greatly shortened.Accept the mode of style, the various advanced person such as CD, E-mail can be passed through Means, the time of typically drawing a design is less than a working day, and the cycle that tradition is drawn a design is typically at about one week.

It is greatly reduced additionally, due to the simplification of the technique cost that makes to draw a design.Draw a design the shortening in cycle and the reduction of cost of drawing a design, This, under current Time is money, the market competition rule that efficiency is most important, brings more city to enterprise undoubtedly Field opportunity.

The set normal complexion that the principle of the most ink-jet printed technology makes its product break traditional mode of production spends back the restriction of length, can So that weaving face fabric realizes the printing effect of top grade printing.

Owing to ink-jet printed technology can use digital pattern, carry out colour measuring & colour matching, spray printing through computer, so that The color of digit printing product can reach 16,700,000 kinds in theory, and the chromatography breaching traditional textile printing and dyeing style limits, Particularly in the printing to the patterns of high precision such as color gradient, moire, ink-jet printed have the most especially without comparable The advantage intended.It addition, the pattern of Conventional decal suffers from the restriction of " spending back " length, and ink-jet printed technical process In can not there is the concept of " spending back ", thus be greatly expanded the space of Textile Pattern Design, improve the shelves of product Secondary.

The most ink-jet printed production is truly realized the production process of small lot, fast response, and production lot is unrestricted.

Owing to ink-jet printed production process all realizes computerized digital production, so that production chains carries significantly Height, some products even can realize delivery on the same day, immediate delivery.Further, since the application of computer technology, print The serial pattern of same pattern difference tone, and the constantly amendment of color is become by designer by pattern in process of production Ink-jet printed production is different from the big technical advantage that Conventional decal produces.

The most high-precision jet printing process makes in jet printing process without water without mill base.

In jet printing process, the use of dyestuff " is distributed according to need " by computer so that in jet printing process, does not contaminate the waste of material, Emit no waste water, by computer-controlled jet printing process, do not produce noise so that jet printing process does not produce pollution, Achieve Green production process, so that high energy consumption, high pollution, the life of high noisy in the past has been broken away from the production of textile printing Product process, it is achieved that low energy consumption, free of contamination production process, brings a technological revolution to the production of textile printing and dyeing.

Along with the speed issue of one of the progress of technology and ink-jet printed bottleneck is substantially achieved solution, the most ink-jet printed The proportion occupied in printing in textiles is increasing, in printing in textiles, and polyester fabric, silk fabric, cotton fabric In etc. shared must in continue to increase.Only before the several years, ink-jet printed also only reside within draw a design on, even if there being order, Also tens of rice it is limited only to, the little order of hundreds of meters；At present, the ink-jet printed order of thousands of meters is the most common, number Myriametre, the ink-jet printed order of even 10 myriametres is the most rarely seen.Along with the continuation of ink-jet printed speed improves, cost Continuing to decline, the real ink-jet printed epoch will arrive, and this time will not too late, also with regard to 2-3 within.

In the prior art, the ink-jet printed of textile is divided into direct-injection stamp and transfer printing.Transfer printing is oozed because having Thoroughly the best and be suitable only for the deficiency of polyester fabric, if so textile at present ink-jet printed based on direct-injection stamp.Spin The direct-injection stamp of fabric must carry out pre-treatment starching to textile before requiring stamp, and the purpose of starching is the table at textile One layer of ink-jet ink absorbed layer of topcoating cloth, and on the dyestuff being added thereto, contaminate the chemical assistant required for fiber.More than Suo The purpose of slurry has two: one to be absorption air brushing ink-jet ink on fabric, is allowed to become thickness, it is to avoid the trickling of ink Or imbibition, make pattern profile keep clear；Two are to provide the chemical assistants that dyestuff and fiber occur to combine, such as hygroscopic agent, Alkaline agent or acid agent etc..

In the prior art, the slurry of Pretreatment of textile starching is all water paste, and it is first to absorb ink-jet print The printing gum of flower ink is soluble in water, adds hygroscopic agent, acid agent or alkaline agent, stirs, become pre-treatment starching Slurry, by this slurry by padding or be coated with on the textile, dry, moisture evaporation becomes ink-jet ink absorption Layer；In theory, because ink-jet ink is also water-base ink, so the starching amount on every square metre is exactly that this spins on textile Fabric ink receptive layer every square metre can absorb and be thickened the amount of fixing ink-jet ink.

For hydrophilic fabric, good water absorption itself, Saturated Moisture Content is big, thus upper use when padding starching Slurry amount is big, and its starching amount is generally capable of up to more than the 100% of dead weight, and even up to 150%；Ink-jet after its drying Ink receptive layer is relatively thick, it is possible to absorbs and is thickened the amount of fixing ink and also can reach the 150% of deadweight, according to mesh For the quantity of ink of first ink-jet printed the most dark 40 grams/m, hydrophilic fabric inking water absorbed layer is fully able to absorb And fix, it is possible to fully meet existing ink-jet printed requirement.

But, padding starching because starching amount is big, its slurry is covered with the tow sides of fabric, and ink-jet printed needs only to The surface coloring of fabric, the slurry of reverse side does not work, and adds the energy consumption of drying and the burden of washing on the contrary, no It is beneficial to energy-saving and emission-reduction.At present, the starching mode of single spreading progressively replaces traditional pads mode, becomes ink-jet printed Main flow starching mode；So bringing a problem, the reduction of starching amount so that ink receptive layer can absorb fixing spray The amount of ink ink the most significantly reduces, and hardly results in deep heavy colour so the most ink-jet printed.Ink-jet printed In, general ink-jet ink is that CMYK tetra-colour cell closes formation, and four kinds of ink-jet inks are by different nozzle ejections, every kind of ink Water its maximum ink amount that can spray in ink-jet decorating machine is set to 100%, and when ink-jet printed, tetra-kinds of inks of CMYK are equal When being 100%, it is the maximum ink amount that ink-jet decorating machine can obtain that i.e. four kinds inks add up to the ink amount of 400%；Existing skill In art, ink-jet printed maximum ink amount is typically only 250%.

And for hydrophobic fiber fabric, because its Saturated Moisture Content is little, even if so padding starching mode, its starching Amount is typically only for the 30% of deadweight；That is, say, that in the prior art, the direct-injection stamp of hydrophobic fabric The ink jet ink water yield can not exceed the 30% of own wt, so direct-injection hydrophobic fiber fabric is for dark color in prior art For, there is great difficulty；Especially for slim hydrophobic fiber fabric, can only print light, in printing Time dark, can be because the ink receptive layer of fabric can not absorb and solidify ink-jet ink and make ink trickling imbibition so that Flower pattern obscures.

Just because of this, in prior art, in the fabric of hydrophobic fiber, polyster fibre uses the easy distillation of small-molecular-weight Disperse dyes make ink-jet ink, first air brushing on transfer paper again at about 200 DEG C by the air brushing face of fabric Yu transfer paper Laminating so that disperse dyes distil, in upper dye to polyster fibre；This mode has several deficiency: one is at high temperature Reason, the Boardy Feeling of fabric, comfort declines；Two is that dyestuff only upper dye is at fiber surface, it is impossible to permeate in face liber Internal；Three are because dyestuff originally as the disperse dyes that easily distil, and sublimation reliability is not enough；These a few deficiencies all limit ink-jet Stamp use on polyster fibre.

So, how to improve fabric in prior art and, to ink-jet printed ink absorption amount, reduce the upper of hydrophilic fibers fabric Slurry amount, thus the sewage discharge of road washing after reducing；For hydrophobic fiber fabric, how to improve existing ink-jet printed color Deeply, a problem demanding prompt solution has just been become；

And in printing in textiles, stamp precision is it is still further preferred that traditional manual thermal station version stamp, and it is first to treat printed fabric It is laid on a long platform that can heat, then uses the screen frame of the silk screen that stretches tight to print design above, it It is to print next chromatography again after previous chromatography is dried, so having extremely excellent contour sharpness.But, along with market Growth to the demand of printed fabric, high efficiency continuous way automatic printing mode such as PLATE SCREAM PRINTING, ROTARY SCREAM PRINTING and roller Stamp progressively replaces hand printing becomes the main flow in stamp market.Because the reason of production efficiency, PLATE SCREAM PRINTING, cylinder print Flower and roller printing often use the stamp mode that wet pressing is wet, say, that when many topping printings, concentrator above After being printed on fabric, without drying, when hygrometric state, just printing next chromatography, this often results in the fuzzy of flower pattern. In order to solve this problem, numerous colourists test a lot of methods.Such as, stoke company of Holland uses every The mode of off the net the logical freezing liquid in set garden, face off the net for Mei Tao garden is passed to the freezing liquids such as liquid nitrogen by it so that be printed on fabric Concentrator at once freezing freeze, fuzzy with the flower pattern of avoiding rear road and drag color, this is cost and costliness thereof；Always Up to the present, the Printing for fine also have to select manual thermal station version stamp mode to carry out；So how The flower pattern of the stamp mode that solution wet pressing is wet obscures and drags the deficiencies such as color is also the technical issues that need to address of the present invention.

Summary of the invention

The technical problem to be solved is to provide a kind of stamp pre-treatment slurry, to solve existing ink-jet printed technology Middle hydrophilic fibers textile sizing amount is big, the deficiency that during washing of rear road, wastewater discharge is big；Solve hydrophobic fabric to print for direct-injection Light color can only be printed during flower, it is impossible to deficiency dark in printing, the most also solve the PLATE SCREAM PRINTING in existing printing in textiles, The flower pattern caused due to the stamp mode that wet pressing is wet in ROTARY SCREAM PRINTING and roller printing obscures and drags the deficiencies such as color.

The present invention also to solve the technical problem that the preparation method being to provide above-mentioned slurry.

For solving above-mentioned technical problem, the thinking of the present invention is: because as the overwhelming majority of ink-jet printing ink absorbed layer Printing gum be dissolved only in water, be undissolved in organic solvent, say, that the most most of print Flower thickener will not swelling；Utilize their this characteristic, by ink-jet printed pre-treatment sizing material by water paste Change organic solvent-borne slurry into, by the printing gum attrition grinding insoluble in organic solvent, add in organic solvent-borne slurry, Or the printing gum insoluble in organic solvent is added in organic solvent-borne slurry, then grinds, become organic solvent-borne spray Ink-printed pre-treatment slurry；Because printing gum is not dissolved in organic solvent, the most dispersed it is suspended in organic solvent Slurry in, so, the amount of the printing gum in organic solvent-borne slurry can greatly be stuck with paste more than stamp in water paste The amount of material；It addition, for hydrophobic fiber, fiber itself is oil loving, so organic solvent-borne sizing material exists Bigger starching amount is had on hydrophobic fiber fabric；So the ink-jet ink that the sizing material of organic solvent-borne is formed after drying The ink receptive layer that the thickness of absorbed layer is formed after the most greatly drying more than water paste starching, has bigger ink jet ink Water absorbtivity.Equally, this ink receptive layer is for flat textile product stamp such as PLATE SCREAM PRINTING, ROTARY SCREAM PRINTING and roller printing Concentrator also there is extremely strong absorbability, within the extremely short time, concentrator can be dried and avoid wet pressing The flower pattern of wet stamp mode obscures and drags the deficiency of color etc..

According to above thinking, technical scheme is as follows:

A kind of stamp pre-treatment slurry, it includes the component of following percentage by weight:

Described stamp pre-treatment slurry is preferably ink-jet printed pre-treatment slurry.

Above-mentioned stamp pre-treatment slurry, when ink-jet printed, preferably comprises the component of following percentage by weight:

Wherein, every water that can be dissolved in, form thick slurry, and the thing chemically or physically reacted does not occurs with dyestuff Matter all can be as printing gum；The described printing gum insoluble in organic solvent is a lot, and it is divided into natural paste and conjunction Become thickener；Natural paste have sodium alginate, bentonite, glucidtemns, dragon glue, polysaccharide material, yellow starch gum or I Primary glue etc.；Synthetic thickener kind is a lot, including etherification starch, etherified cellulose, etherificate seed glue, polyvinyl alcohol or Acrylic compounds etc..

Wherein, those skilled in the art all know, when dyestuff is reactive dye, use alkalescence pre-treatment slurry, are printed When fabric is cotton or silk fabric, the stamp that printing gum does not reacts with reactive dye under the conditions of must be chosen to be at this Thickener, such as sodium alginate, sodium carboxymethyl cellulose, carboxymethyl starch sodium, bentonite etc..

Wherein, the percentage by weight that the printing gum insoluble in organic solvent is shared in pre-treatment slurry is according to printing gum The character difference of itself is widely different；Such as special full-bodied hydroxypropyl methyl cellulose (belonging to etherified cellulose), The viscosity of the aqueous solution of its 2wt% can reach 100000～200000mPa.s, this printing gum consumption in the present invention Only need 1wt%, it is possible to reach well to fix the effect of ink-jet ink；And for the less glucidtemns of viscosity For yellow starch gum, it is necessary to the consumption reaching 30wt% can be only achieved good ink-jet ink fixed effect.

Wherein, the described polymer substance being dissolved in organic solvent be can only be dissolved in organic solvent polymer substance or can It is dissolved in organic solvent and can be dissolved in again the polymer substance of water；Wherein, the described polymer substance that can only be dissolved in organic solvent Must select high viscosity, range of viscosities is generally 2wt% concentration, the kind of more than 3000mPa.s, because viscosity is the highest, Its consumption is the least, and during the washing of rear road, the residual on fabric is the fewest, affects the least, specifically on the feel of the fabric after stamp For ethyl cellulose, polyvinyl butyral resin or Vinylidene Chloride etc.；Described can be dissolved in organic solvent and can be dissolved in again water Polymer substance be hydroxypropyl cellulose, polyvinylpyrrolidone, pulullan polysaccharide or hydroxyethyl cellulose, Qi Zhongpu Shandong orchid polysaccharide and hydroxyethyl cellulose only dissolve in highly polar dimethyl sulfoxide and amide solvent.When selection does not dissolves in The polymer substance of water makees viscosity modifier, when using full-bodied polymer substance, because the iris action of printing gum, Washing residue is few, slightly affects feel；And use and can be dissolved in organic solvent, the polymer of water can be used for again When matter is as viscosity modifier, not having residue after washing, the feel of printed fabric is better than using water-fast polymer The situation during viscosity modifier of matter, so preferably hydroxypropyl cellulose, polyvinylpyrrolidone and general in the present invention Shandong orchid polysaccharide and hydroxyethyl cellulose are as viscosity modifier.

Wherein, the effect of the polymer substance being dissolved in organic solvent is, one is to make slurry present certain viscosity so that slurry Can be coated with smoothly or pad at web surface；Two is when slurry is liquid, and it makes the viscosity that slurry holding is certain, with Avoid the printing gum suspension aggregate and precipitate insoluble in organic solvent；Three is in coating or to pad on fabric and dry After, the polymer substance being dissolved in organic solvent of addition here becomes the binding agent of printing gum powder, is stuck with paste by stamp Material powder sticks to the surface of fabric, prevents printing gum from coming off.

Wherein, described water absorbing agent be in atmosphere can the material of deliquescence water suction, general conventional in textile printing is urine Element, glycerol.The consumption of water absorbing agent is different with fiber species according to the weaving mode of fabric, and usage variance is the biggest；Right For relatively close high density Nylon Taffeta, water absorbing agent consumption has only to 1% humidity requirement that just can reach when evaporating, And for more open knitted wool fabric, water absorbing agent consumption reaches 20%, when evaporating, pattern profile also can be clear, Not imbibition.

Wherein, described sour agent is for ionizing the hydrionic material of generation in the solution, and it includes organic acid, mineral acid, A few class such as acid salt or strong acid weak base salt, wherein organic acid be generally formic acid, acetic acid, oxalic acid, citric acid, malic acid or Trichloroacetic acid etc., mineral acid is generally hydrochloric acid, sulphuric acid, phosphoric acid or nitric acid etc..Acid salt be generally sodium bisulfate or Sodium dihydrogen phosphate etc., strong acid weak base salt is generally ammonium sulfate etc..In the present invention, because it is contemplated that in organic solvent Dissolving, preferably organic acid is as the sour agent of the present invention, such as oxalic acid, citric acid, malic acid, trichloroacetic acid etc..If When using the sour agent insoluble in organic solvent, acid agent need to be added together grinding with the printing gum insoluble in organic solvent, But this has certain corrosiveness for grinder.Or pre-treatment slurry is added without acid agent, first will treat that printed fabric is used Acid agent processes dries, upper pre-treatment slurry；The amount of acid agent is the most different according to the Acidity consumption of organic acid；At this In the slurry of invention, when printed fabric is nylon or Pilus Caprae seu Ovis, pH value typically regulates between 1.5～6.5, when When using acid stronger trichloroacetic acid, it is thus only necessary to 0.1wt% i.e. can reach this pH value, when using acid more weak Herba Marsileae Quadrifoliae During fruit acid, i.e. usage amount reaches 8wt%, and its pH value is also in the range of it.

Wherein, described alkaline agent is the material that can ionize in the solution and generate hydroxide ion, and it is generally inorganic base, has A few class of machine alkali, basic salt or strong base-weak acid salt.Wherein, described inorganic base is generally sodium hydroxide, calcium hydroxide or hydrogen Potassium oxide etc., described organic base is generally ethylenediamine or triethanolamine etc., and described basic salt is generally alkali formula chlorine Changing calcium etc., described strong base-weak acid salt is generally sodium bicarbonate, potassium bicarbonate, potassium carbonate, sodium trichloroacetate, tertiary sodium phosphate Or soda etc., using most in cellulose fibre printing with reactive dye is exactly strong base-weak acid salt, and preferably organic base is made Alkaline agent for the present invention；；If use the alkaline agent insoluble in organic solvent, need to be by alkaline agent and insoluble in organic solvent Printing gum is added together grinding, but this has in certain corrosiveness, or pre-treatment slurry for grinder and is added without Alkaline agent, first will treat that printed fabric alkaline agent processes and dry, upper pre-treatment slurry.

Wherein, described organic solvent is organic solvent of ketone, based organic solvent, alcohol organic solvent, glycol ethers Organic solvent, amide-type organic solvent or dimethyl sulfoxide；Wherein, described organic solvent of ketone is acetone, butanone or first Base isobutyl ketone etc.；Described based organic solvent is ethyl acetate or butyl acetate etc.；Described alcohols is organic molten Agent is methanol, ethanol, isopropanol or isobutanol etc.；Described glycol ethers organic solvent is glycol monoethyl ether, second 2-ethoxyethanol, ethylene glycol monobutyl ether, propylene glycol monomethyl ether, dihydroxypropane single-ether or propylene glycol monobutyl ether etc.；Described Amide-type organic solvent be dimethylformamide or dimethyl acetylamide etc..In the present invention, because it is contemplated that cost and Environmental Factors, preferred alcohol is as the organic solvent of the present invention.

The preparation method of above-mentioned stamp pre-treatment slurry, the method comprises the steps:

(1) grinding of printing gum: the printing gum insoluble in organic solvent is inserted attrition grinding in grinder, Printing gum after grinding, standby；Or, the printing gum insoluble in organic solvent is inserted with organic solvent simultaneously Grinding machine for grinding is pulverized, and releases the mixture of printing gum and organic solvent, become printing gum mother solution from grinder, Standby；

(2) interpolation of printing gum and the dissolving of printing assistant: the printing gum after the grinding obtain step (1) adds Enter in organic solvent, add water absorbing agent and acid agent or alkaline agent (when water absorbing agent value is 0%, is just added without water absorbing agent； When acid agent or alkaline agent value are 0%, just it is added without acid agent or alkaline agent), stirring and evenly mixing；Or, step (1) is obtained To printing gum mother solution add in organic solvent, add water absorbing agent and acid agent or alkaline agent (when water absorbing agent value is 0% Time, just it is added without water absorbing agent；When acid agent or alkaline agent value are 0%, just it is added without acid agent or alkaline agent), stirring and evenly mixing；

(3) viscosity adjustment: add the polymer substance being dissolved in organic solvent in the system that step (2) obtains, stir, It is configured to ink-jet printed pre-treatment slurry.

In step (1), the fineness needed when printing gum insoluble in organic solvent grinds is upper according to rear road fabric Sizing process is different and different；If use garden, rear road is starched on the net, the fineness of printing gum is it is generally required to be less than 200 mesh； If using scraper starching, intaglio printing starching and pad starching, then fineness is needed to be less than 800 mesh.

In step (1), when printing gum becomes printing gum mother solution with organic solvent mixed grinding, the weight of printing gum Printing gum and less than the 40% of organic solvent gross weight during for grinding.

In step (3), the viscosity of pre-treatment slurry is the most different according to the different viscosities of starching mode；If the garden of use net Or when padding starching, its viscosity is generally 1000～3000mpa.s, and when using intaglio plate roller coat, viscosity be generally 500～ 1000mpa.s, and when using scraper starching, viscosity is generally 3000～6000mpa.s.

Because it is light that ultra-thin hydrophobic fiber fabric is grammes per square metre, generally less than or equal to 50 grams/m.Existing ink-jet printed Pre-treatment slurry be difficult to meet the Dry Sack requirement of ultra-thin hydrophobic fabric, so present invention is especially suited for ultra-thin hydrophobic fabric Ink-jet printed pre-treatment starching.

The situation during use of this ink-jet printed pre-treatment slurry is such that in the pre-treatment slurry of organic solvent-borne print Flower thickener is not because dissolving, only by grinding the pre-treatment slurry being uniformly suspended in the present invention in molecule In, pre-treatment slurry is dissolved with the polymer substance that can be dissolved in organic solvent, making pre-treatment slurry is certain denseness, Prevent printing gum aggregate and precipitate；Further, added with promoting to contaminate on dyestuff the printing assistant of fiber in pre-treatment slurry.

Time ink-jet printed, first above-mentioned slurry it be coated with or pad on fabric, drying, clot, standby；Organic solvent is waved After Faing, printing gum will the surface of fabric formed one layer of fine and close ink-jet ink absorbed layer, before added be dissolved in The polymer substance of organic solvent here becomes the binding agent of printing gum powder, and printing gum powder is sticked to fabric Surface, prevent printing gum from coming off.

By above on the fabric loading ink-jet decorating machine of pre-treatment, with corresponding ink-jet ink stamp, when the spray of aqueous Ink ink air brushing is when web surface, and printing gum is dissolved by ink, and ink becomes thickness, and ink is fixed, stamp flower Type keeps clear-cut；The implementation process of the present invention finds, because the stamp in web surface ink-jet ink absorbed layer The amount of thickener is very big, even if so ink-jet printed time maximum quantity of ink, the ink amount of i.e. 400%, for the most frivolous Polyster fibre fabric (grammes per square metre is only 20 grams/m), also can absorb fixing easily；In ink-jet printed, typically Ink-jet ink is that CMYK tetra-colour cell closes formation, and four kinds of ink-jet inks are by different nozzle ejections, and every kind of ink is in ink-jet In printing machine, its maximum ink amount that can spray is set to 100%, and when ink-jet printed, tetra-kinds of inks of CMYK are 100% Time, it is the maximum ink amount that ink-jet decorating machine can obtain that i.e. four kinds inks add up to the ink amount of 400%；In routine aqueous When pre-treatment slurry processes fabric, ink-jet printed during, even if the heavily fabric of hydrophilic fibers, ink-jet ink is Great Mo amount typically can not be more than 250%, and otherwise flower pattern imbibition can cause soft edge.

The most ink-jet printed complete after, printed fabric enter drying unit, dry；Again through dyestuff set, washing, fixed Type, i.e. obtains ink-jet printed fabric.

It addition, present invention applicant is it was also surprising that the fabric after pre-treatment slurry of the present invention processes is to common PLATE SCREAM PRINTING, ROTARY SCREAM PRINTING or roller printing slurry have the strongest absorbability.At the slurry of the process present invention Fabric after reason, when fabric being carried out stamp by the method for common PLATE SCREAM PRINTING, ROTARY SCREAM PRINTING or roller printing, prints Concentrator on fabric is i.e. absorbed by the pre-treatment slurry on fabric without moisture within drying in 10 seconds, dry Dry, flower pattern has fabulous contour sharpness；And without the present invention process fabric during stamp, for plain net Stamp and ROTARY SCREAM PRINTING because can not be dried in time at stamp, before a set of printing paste, a set of cylinder can be stain down Reverse side, causes and drags color；Particularly PLATE SCREAM PRINTING, is also easy to impression screen frame edge occur, and this is for hydrophobic frivolous Fabric is especially apparent, and even causes high-volume substandard products stamp to be produced and can not be normally carried out down time serious.And roller Stamp, situation is the most serious, while causing and dragging color, before a set of printing paste also can be mixed into the print of next chromatography In flower slurry, cause colour contamination, and whole printed fabric color is changed, substantial deviation client's sample, easily cause Large batch of substandard products；And after stamp, it is necessary to entering oven for drying, this process dried is often several minutes, so, During drying, often or there is migration and imbibition in concentrator, causes pattern profile to obscure；

Beneficial effect: the ink-jet printed pre-treatment slurry of the present invention, is greatly improved the content of printing gum in slurry, makes In textile inkjet printing for hydrophilic fabric, starching amount during pre-treatment can be substantially reduced so that ink-jet printed take turns While wide definition and surface tinctorial yield improve, quantity of wastewater effluent when road is washed after reduction, beneficially environmental conservation； For hydrophobic fiber fabric, the ink absorption amount of direct-injection stamp can be greatly promoted so that deep heavy colour can be at direct-injection stamp In be achieved.It addition, the pre-treatment slurry of the present invention, for common PLATE SCREAM PRINTING, ROTARY SCREAM PRINTING or roller printing In, the drying time of concentrator be can greatly shorten, migration and the imbibition of slurry prevented, the wheel improving flower pattern is cleaned up Clear degree, is greatly improved percentage of A-class goods during stamp.
