Description
Technical field
The invention belongs to process field such as fabric, especially relate to a kind of silk broadcloth thermal transfer printing method.
Background technology
So-called transfer printing, several method such as be divided into distillation, migration, fusion and peel off.Present technique only relates to the sublimed method transfer printing, also claims thermal shift assay or gas phase transfer method.
Since the sixties in last century, vapour phase transfer printing (hereinafter to be referred as transfer printing) has begun successfully to be applied to production practices.It selects the DISPERSE DYES with distillation character for use, furnishing mill base and printing ink, be printed on the paper substrate in advance, then with transfer printing paper with have the chemical ﹠ blended fabric of obvious vitrification point such as terylene, nylon, acrylic fibers, triacetate etc., positive mutually the applying, under the heating and pressurizing effect, with the design transfer on the paper to weaving face fabric.
Transfer printing and traditional roller printing, ROTARY SCREAM PRINTING, PLATE SCREAM PRINTING compare, and have:
(1) equipment is simple light and handy, floor space is little, small investment, technology are simple, easy to operate;
(2) do not need set and washing, no contaminated wastewater behind the textile printing;
(3) can reproduce truly pattern and color and luster on the transfer printing paper, decorative pattern is meticulous, third dimension is strong, fastness is high, especially can print traditional printing method the levels are rich that can not print and how much strict Pareto diagrams;
(4) be particularly suitable for the stamp that bigger knitted fabric of shrinkage and synthetic fiber are out of shape fabric;
(5) yield rate is much higher than the advantage of traditional stamp yield rate, is subjected to the favor of vast manufacturer deeply.
, the transfering printing process that forms from the sixties can only be implemented having on the chemical ﹠ blended fabric of obvious vitrification point, has limited the development of this stamp mode.So, seek the developmental research of transfer printing on the natural fabric except above-mentioned chemical ﹠ blended fabric such as real silk, cotton textiles, linen.
Silk broadcloth air brushing technology is exactly under such prerequisite, adopt the digital code spray-jet printing technique, directly be printed on the silk fabric face via the computer digital injection by pattern,---washing---aftertreatment technology that rotates back into evaporating of traditional printing technology again, be a forced technology of having to take the second best, but still a kind of good silk broadcloth printing technique of can yet be regarded as.
Transfer printing on natural fabric, according to present report, there is Japan to apply the chlorobenzoyl chloride method for transfer printing of the cotton of island company, this method on cotton color depth and vividness can with terylene than beautiful, but the gas toxicity of producing reaction is too big, have corrosivity simultaneously, must adopt special equipment under the air-proof condition of strictness, to carry out.Day Benshen how county's commerical test acetylation---the styrene-grafted transfer printing method of real silk, must in anhydrous dimethyl formamide organic facies, carry out, limit its industrialized realization.The U.S. delivers success of the test real silk transfer printing in August, 1991, claims to have obvious excellent characteristic.The research of Germany Si Boli Stark international corporation through improved transfer printing paper, can obtain printing quality on silk, wool fabric, but later process still needs vapour steaming colour fixing and washing, to reach the carrier auxiliary agent on fixation and the cleaning fabric with a kind of.Simultaneously, Switzerland Sublistatic, all there are the scientific research report in company such as Britain Holliday and U.S. Southern Research Inst etc.
To so far, the real company that more successfully realizes transfering printing process on natural fabric is " Cotton-Art " (cotton technology) of Denmark Dansk register of company in the world.It is to adopt REACTIVE DYES to be modulated into special mill base to be printed on the special paper substrate, and then by on special " Cotton-Art " transfer printing machine of affiliate Germany Eduard Kusters company earlier through preliminary treatment, finish through three breaker roll HIGH PRESSURE TREATMENT again.According to reports, this technology can success is implemented in transfer printing on the COTTON FABRIC, but the transfer printing device that must select for use Denmark Dansk company to produce, investment cost is quite expensive.
Domesticly can only more successfully realize transfer printing on chemical ﹠ blended fabric at present, the transfer printing aspect natural fabric does not still have too much report.Existing report is confined to laboratory or paper mostly, really satisfies market and customer demand, get the nod and the natural fabric transfer printing of successful commercial applications still few.
Many researchers wish DISPERSE DYES is transferred to process application on the chemical ﹠ blended fabric to natural fabrics such as cotton textiles.But at present, the problem that transfer printing exists is:
A. bright-colored degree is not enough, and just tinctorial yield is not enough.
B. fastness can't satisfy the requirement of taking washing fully.
At present, carry out the straight spray printing flower of number, but can not save technologies such as the fixation of back and washing by utilizing REACTIVE DYES or ACID DYES.So similar technology such as " cotton-art " is not promoted and is come.And increased the defect that speed of production is extremely slow.Also like this in Europe.
The silk broadcloth stamp, from the fifties beginning in last century, silk screen leaks version seal technology and the automation printing equipment develops so far always, has developed into very perfect and is widely used in technology and the equipment that the silk broadcloth stamp is produced.The develop rapidly of modern computer science and technology thereupon, the color separation of preceding road-----pattern of this technology, retouch original text, plate-making, sample, replaced by computer painting technology, utilize REACTIVE DYES or ACID DYES to carry out the straight spray printing flower of number, aspect silk broadcloth small lot batch manufacture and antenatal drawing a design, manifest the fast-developing impetus.
But with the target that people pursue, the Shang Youyi step is distant, and this target is exactly to pursue the transfering printing process technology of similar chemical ﹠ blended fabric.Because the color achievement of beating technology of computer, pursue true to nature and quick, be fit to the personalization of product, the dream that has been the technology for printing fabric made technical development is generally desirable, has at first realized this target on fiber product, but on the silk broadcloth product, on heat transfer technology, run into obstacle, be the problem of domestic and international silk broadcloth dyeing circle engineering and technological research for many years, before us, the someone breaks through as yet always.
Summary of the invention

Because by the transfer paper pattern transferring, ink is sprayed on earlier on the transfer paper, is depressed on the silk by commentaries on classics again; Therefore output program must be fit to the characteristic of ink, has worked out color mode conversion and two special steps of halftone process for this reason.
The color mode transfer process is: computer picture is converted into 4 CMYK orders from 24 RGB patterns.
The halftone process process is: the cell position that each of threshold has N pixel all has a gray value N
2, a numerical value between the selected 0-255 is as gray value; If this value of a threshold position is more than or equal to the gray value that will print, does not just print the units corresponding position; If this value is less than the gray value that will print, the units corresponding position will be printed.
In conjunction with above two steps, ink is sprayed onto on the transfer paper, just can be made into the transfer paper that is fit to the silk trans-printing.Transfer paper must cooperate the pretreated silk of pretreating reagent through the present invention program, picture could be printed on the silk, and the silk product that obtains has the depth of color that is better than existing product, gorgeous degree and COLOR FASTNESS.
The pigment dispersion transfering printing process can only be implemented having on the carrier of obvious vitrification point, as chemical ﹠ blended fabric such as terylene, nylon, acrylic fibers, triacetate and pottery etc., chemical fiber plus material product and ceramics have had ripe products in circulation in the city on the market.Because silk broadcloth is natural protein fibre, does not possess the essential specific condition of this technology, common silk fabrics can't adopt the pigment dispersion transfering printing process.
But the superiority of pigment dispersion transfering printing process is conspicuous.In order on silk fabrics, to adopt this technology, be exactly the necessary condition of on silk fabrics, creating.In principle, as long as be coated with the material that one deck has obvious vitrification point, just can realize our imagination on the silk fabrics surface.But, to do like this in the practice, it is that the one's best quality of silk broadcloth uniqueness also can lose greatly that problem is thereupon arranged, and says in the row, and silk broadcloth has been become chemical fibre, loses more than gain.Make firm attachment capacity on the silk fabrics have the material of obvious vitrifying performance the time, do not influence the one's best quality of silk broadcloth again, this just can not simply be coated with this material of last layer on silk fabrics.
High molecular polymer, the chemical fibre that circulates on the market all belongs to high molecular polymer, has this obvious vitrifying performance, the high molecular polymer of having made, as the adhesive class commodity that circulate on the market, adopt this auxiliary material also in a large number in the textiles dyeing and printing process,, but have shortcoming such as feel is not good enough mostly as COAT PRINTING, pigment dyeing etc., on silk broadcloth, this shortcoming just especially the people can not be accepted, and therefore, can not prolong with common way.
High molecular polymer is with high polymer monomer with polymerizing power, under the condition that is fit to, carries out that polymerisation generates.The control different polymerization degree is controlled specific polymerization process condition, can obtain the product of various different Practical Performances.The present invention adopts acrylic ester monomer exactly, make the polyacrylate macromolecular compound of particle in following polyacrylate macromolecular compound of 100 nanometers or modification, under the heat transfer process heat condition, anchor on the silk broadcloth, thereby obtain to realize the necessary condition of pigment dispersion transfering printing process, the one's best quality of unconspicuous again loss silk broadcloth simultaneously keeps the jewelry gloss and the fine and smooth smooth feel of silk broadcloth uniqueness, does not lose the ventilative quality of moisture absorption.
The various chemical analysis of the pretreating reagent of silk broadcloth thermal transfer printing method, under the heat condition of heat transfer process, possessed the condition of polymerisation, therefore, it has finished the generation of high molecular polymer simultaneously and the distillation of pigment dispersion is shifted, and has reached the purpose of thermal transfer printing.
Therefore, the present invention has following advantage: present technique is by homemade chemicals treatment silk broadcloth, and again through hot transfer printing, silk broadcloth just can obtain and be equivalent to the depth of color of hot transfer printing on the chemical ﹠ blended fabric, gorgeous degree and COLOR FASTNESS; Realized the intact positive technology of the hot transfer printing of silk broadcloth; Solved: 1, Dry Sack rate problem can obtain rich and gaudy colourity; 2, solve the washing fastness problem of color, can obtain the fastness of standard-required; 3, by digital technology, solved the recurrence problem of pattern color, can obtain description effect true to nature.The precision of printing improves with the precision of pattern itself.
The specific embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment 1:
Step was divided into for five steps:
1, image importation: can adopt modes such as digital camera, scanner that picture is imported computer; Image resolution ratio requires more than 300dpi; The image processing part: utilization PhotoShop handles.
2, tone levelling on computers, selects for use the RIP various software can reach the purpose that tone is corrected.The final color of silk broadcloth thermal transfer printing method, will be through the transfer process of pigment, pigment has the process of color development, so in color that shows on the computer display screen and the color that is printed on the transfer paper, be that color different and final acquisition on silk broadcloth also is very different; Reach above requirement by color mode conversion and halftone process.
Tone levelling is finished one by two steps: the color mode conversion, its two: halftone process.
1) color mode conversion
The effect of color inkjet printer is a coloured image that computer is produced or print in high quality from the coloured image of scanner.In computer, the color of each point all needs RGB (R is that red/G is green/B for the blue) information with one 24 to store on the image, 8 bit representation redness wherein, 8 bit representation greens, 8 bit representation bluenesss.
RGB color on the screen can not directly print, and this is by luminaire, computer display for example, and additive color process by red, green, blue three looks that send produces color.And fabric colouring colour display screen shows process, then is by after absorbing the light wave of different wave length at the pigment on the fabric, the synthetic color of the light wave that remaining light wave reflects.Display is not luminous, just produces blank screen, and all visible light wave superpositions just produce white together.In contrast, the fabric color is to produce color by subtractive process, and a fabric that does not have red ink paste used for seals to cross has reflected the light of all visible light wave components, thereby presents white.
The colour print process has been used the different pigment of CMY (C as cyan/M as magenta/Y for yellow), sponge the light wave of part wavelength after, present different colors.Cyan absorbs red light wave, makes the image that prints be aquamarine blue; Similarly, magenta red ink absorbs green light wave, makes the image that prints be blue red.With the whole visible spectrums of ink absorption of (cyan+magenta+yellow+black) combination, image presents black.
The image that computer shows with the RGB pattern, still, printer prints must be used the CMY pattern, and this just need be transformed into the CMY pattern to color from the RGB pattern.In addition, each nozzle on the ink-jet printer all is two-symbol, and this that is to say that it is merely able to be opened or closed.So, except image transitions from the RGB pattern to the CMY pattern, image information also must further convert a series of binary bits (ON/OFF) order of delivering to printhead to, comprising cyan (ON/OFF) order, magenta (ON/OFF) order and yellow (ON/OFF) order.Printer (for example trade mark is the printer of Z31 for the Lexmark model) for two ink guns (black printer ink cartridge+one a colour print print cartridge) also must send the order of a series of black (ON/OFF) to printer.When having increased black in the CMY pattern, this pattern just is called the CMYK pattern, and wherein " K " just is meant black.Software driver is changed computer picture by " color conversion " from 24 RGB patterns, become monochromatic and employed 4 CMYK order of color print head.RGB represent to convert to first process that CMY represents be one simple, check process by the form of pixel, the performance of color in this process control, it has specified each planes of color to print the relative populations of required ink, determines the weight of visual Dry Sack.
2) halftone process
Color conversion process, that need to have determined to print counts, and halftoning process has been determined to print counts in the where printing of fabric, determine the color change of image, printer only uses the ink of four kinds of colors by this process, just can produce no ladder color on fabric.
The point that monochromatic binary bit is printed (for example single-colour ink-jetting printer or laser printer) can only be to open or close two states, can not print the part of a point, or reduces the intensity of point.In the position (pixel) of each point of fabric, or print point, or " no point ".For the text printing of ater, this is just enough.But when printing the black white image of the different depths, software driver must use a kind of technology that is called halftoning.This technology is identical with the used technology of seal photo, prints off the image depth difference of coming, and is what that are printed pixel to determine that they can give people's visual effect by, automatically constitutes the real world images with associative perception, stereovision with these points.
Halftone process, software driver need be slit into the unit to pattern.A pixel is exactly a some position, and a unit is exactly the picture element matrix of a rectangle.When printing black in a unit, all print with black point positions all in this unit.When printing a white space, institute has a position not print.When printing different depth color, have only some some positions to be printed in this unit, does not print other some positions, and color is shallow more, and counting of being printed in the unit is just few more.For example, during 25% gray scale, have only 1/4th point to be printed as black in the unit, and during 50% gray scale, will have the point of half to be printed as black.Then on fabric the tiling these unit, this just can produce desired image.
What of the grey level that can print are the quantity of pixel determined in the unit in this unit.Can there be 16+1 level gray scale one 4 * 4 unit, and 8 * 8 matrix can have the different gray scale of 64+1 level.Monochromatic halftoning can only be used black ink, and it is the same to reproduce the image with several different depths, and color halftoning can reproduce abundant colors only with the ink of four kinds of colors.Color halftoning and monochromatic halftoning are similar, but color halftoning is not to create with single stain pattern, but create with three different layers or planes of color: one is cyan point plane, and one is pinkish red some plane, and one is the yellow dots will plane.These three kinds of plane stacks together, add black outward, just can reproduce almost unlimited color.
The diffuse images halftone technique has been divided into four color planes, each Color plane to pattern, can handle through artificial levelling, just want the some position of engineers and technicians, reach and reconfigure pattern, the operability of present technique is strengthened according to four colors of the needs of product levelling.
Four Color plane all are divided into the unit, and there is different dot patterns each unit, and these unit of tiling produce image on fabric then.Pixel count (point) in unit has determined the number of greyscale levels that monochrome printers can reproduce.For example, in one 4 * 4 black and white unit, we wish to print (black=255 with gray value 64; In vain=0.) we will determine which pixel prints with a threshold " sieve ", the used silk sieve of threshold " sieve " and impression case on fabric the spitting image of, determine that some position allows printing, in some position non-print.Each cell position of threshold " sieve " all has a gray value, and its maximum permissible value is 255.Whether to print in order to determine a concrete location of pixels, we are the gray value that will print (gray value is 64 in this example) and threshold, and " " this value of position is more than or equal to the gray value that will print, and does not just print the units corresponding position for sieve for sieve " the value of gray scale corresponding units position compare: if a threshold "; If this value is less than the gray value that will print, the units corresponding position will be printed.
Pixel count in unit has determined to need the color dot quantity that can print to print how many color dots, is referred to as gray scale, and the point in a kind of dot pattern unit of color is many more, and the depth level of this color is just many more.The diffuse images technology is used to check the gray scale of each point, just looks like that it is can enough different gray level printing the same, actually prints just what of color dot of black (255) or white (0).
Adopt diffuse images method halftone process technology: if be exactly print point not on specific pixel location, the actual grey value is exactly 0, or white, if hope obtains 64 gray value, is exactly 64-0 in this locational error, or 64.If a dot printing is arranged here, then actual grey is 255, or black, though we wish that the gray scale of this position is 64.Therefore in this locational error is 64-255, or-199.To neighborhood pixels, this process is called " Air Brush " process on the driver screen this error of calculating " diffusion ".If error is (promptly having printed stain) born, just reduce the probability that neighborhood pixels is printed stain; If error is positive (promptly not having print point), just improve the probability that neighborhood pixels is printed stain.Therefore, adopted diffuse images method (being also referred to as contiguous process) halftone signal to handle, just the color of replicated image requirement freely comes, like this, by several limited colors, color ink jet printed just can success finish to have reproduced and approach the unlimited gorgeous color of former figure.
3, image output: use ink, select the output of Epson series of drawing shadow color inkjet printer for use, be printed on commercially available weaving with on the heat-transferring printing paper.
The ink that is used for silk broadcloth thermal transfer printing method, print the common requirement except satisfying as digital ink-jet, also need have and to be complementary with pretreating reagent, the present invention finally reaches the practical requirement of the stamp product of various tool silk attributes, therefore aspect the pigment of special chromatic ink of CMYK and four color separation stamps, cyan should be turquoise blue; Magenta is gorgeous blue light redness; Yellow is light yellow; Black is neutral corvinus.Color material fineness requirement reaches 200 nanoscales, has good dispersiveness in water.Various pigment sublimation temperatures are approaching as much as possible, generally use the low form pigment dispersion.
