Description
The present invention relates to make the net making method and the equipment of textile printing half tone.
Textile printing in brief, is with the paste (be called for short " mill base ") that is added with dyestuff, by the screen cloth pore, draws together to print to and produces color on the fabric, and its shape of printing off is determined by the block pattern that stays pore that can be by print paste on the screen cloth.
To transfer to the shape of these patterns and position exactly on the half tone, can not lean on manual directly on screen cloth gluing (describing) stop up mesh and realize.The method that sensitization system net has just been arranged as far back as the fifties, before this method system net, must earlier the former state pattern be described respectively by different colours, make " black and white film ", promptly the pattern form of each color is painted on the dedicated transparent film with black ink.So-called " sensitization system net method " is exactly that photosensitive materials such as ammonium dichromate are joined in the special-purpose thickness glue, this glue is applied on the blank screen cloth version then, in the darkroom through low temperature drying, again the above-mentioned color separation black and white film of having described is coated (of the same colour one throws the net) on it respectively, irradiation by the ultraviolet high light, the light transmission part photosensitizer promptly plays sclerous reaction (Here it is " exposure "), make this glue water insoluble, thereby obstruction mesh, and the black that is wrapped on the colour separation film is spent the shape part, because of light tight, and do not have sclerous reaction, and the half tone of exposure is put into water, then this part colloid is promptly dissolved come off (Here it is " development ") after meeting water, show the original pore of screen cloth, can make various required floral designs thus.
This net making method, operation is 37 roads nearly, and manufacturing speed is slow, technology is complicated, and the system net is of poor quality, can not adapt to keen competition situation day by day in the world.
The major defect of tradition net making method:
1, low to the anthosin exactness.Because traditional net making method must have the color separation black and white film, and this film has certain retractility.It changes with the tension variation of operating room's temperature, bag sheet.On the other hand, coating photosensitive plastic coating thickness is also not quite identical on cylinder, causes the bigger variation of cylinder perimeter dimension, has caused bag sheet (Fig. 5) difficulty like this, is not bag sheet deficiency, and it is long to wrap sheet exactly.Simultaneously, the manual operations of standard "+" word line (Fig. 3, Fig. 4) is also very easily produced deviation, therefore, the accurate butt joint of meticulous style coincide, and each cover is accurately superimposed almost to be impossible.Though have taken some precautions in describing in design, color separation, as screen the design and the serpentine open-circuit method of open circuit, the homochromy reason etc. of mediating of the folded look of phimosis, but this produces effect to bulk face style, simple rough style or sand-blind style, and to meticulous style of modern times, rule is little how much, high density grid style is all powerless.
2, spend the shape distortion many.The tradition exposure method, make the colored shape information loss on the colour separation film more, cause distortion, fineness as thin stem mud point, lines fineness, moire level etc. often can not demonstrate fully out, in general, the fineness of flower original text is between 600dpi-1200dpi, fineness, definition is enough, because the order number of the used half tone of general meticulous decorative pattern is many between 135dpi-200dpi, but in the tradition system net, the time for exposure is controlled by rule of thumb, cylinder is between 3-6 minute, plain net is about 1 minute, and this empirical value may make under-exposure or excessive, often can not definitely reflect the true picture of colour separation film.In general, not the site loss, be exactly the site metamorphopsic distortion.This half tone defect often brings the appearance style variation of printing on the finished product.
3, half tone quality instability, fastness are poor.Traditional half tone must have development (Fig. 6) process after being produced on exposure.The development quality is directly connected to the half tone quality.Develop and to be subjected to water temperature, dip time, to wash away pressure, the time, wash away factors of affecting such as uniformity, concerning thin stem, moire mud point, be easy to generate thickness, disconnected stem, defect such as inhomogeneous, and all these operations, estimate all by rule of thumb at present, with the scene, vary with each individual, have very big randomness.Simultaneously, above-mentioned defect is difficult for being found under wet condition, and treats to check out after the half tone drying late, and problem is serious has to reform.
4, the reappearance of flower version making is bad.The quality of finished product flower version is closely related with each process procedure in the system network process, how by rule of thumb particularly gluing, exposure, development, polymerization operation, the tightness that lacks science, so even same individual makees two identical colored nets simultaneously, also can produce thickness, defect such as irregular, this adds the system influence to scoring a goal very big, the printing effect of batch fabric before and after it is related to.
5, the system net time is long.Tradition net making method process procedure is many, speed is slow, in general, carrying out the preparation of net base, after the first-class photoresists, only expose, process such as development, drying, colour-separation drafting, polymerization upper baffle, drying just reaches more than 5 hour, so scoring a goal of the half tone of urgent need, particularly online production added the tangible incompatibility of system.
6, operation is too many, and cumulative errors are big.Because sensitization legal system net operation is 37 roads nearly, and draw normal line, polyphyly manual operationss such as bag sheet so accumulated error is bigger, cause registering (promptly many covers are superimposed) deviation, influence the appearance effect of PRINTED FABRIC.
7, environmental pollution is serious.After the sensitization legal system net exposure, need use a large amount of flushing with clean water during development, and have noxious material such as the chromium of containing to emit serious environment pollution.In addition, what use during exposure is ultraviolet source, and the people who is engaged in this work for a long time very easily suffers from occupational disease.
Since the nineties, various wax spray system network technologies have been developed abroad, in nearly 2 years a small amount of introducing is arranged, this kind equipment adopts and is similar to inkjet technology, and the wax that utilizes the solid preventing ultraviolet is according to the color separation graphics request, and injection covers on the cylinder that is coated with photoresists, expose then, develop ... make printing cylinder at last, the main feature of this technology is to have saved colour separation film and the preceding bag sheet process of exposure, comes down to spray cured replacement film.But defective is still a lot.
1, the half tone quality problems are still serious.Wax spray system net has been got rid of film, has solved the fault that bag sheet error causes, but has produced a lot of new defectives.At first, because the wax of spray orifice ejection drips the figure that the point of formation is not a rule, the wax layer thickness is bigger, and size also has small difference, so that the fineness of style, definition and fineness just seem is good inadequately; Secondly, " flying spot " is a lot of on the finished product cylinder cover of wax spray system net, makes that flower version surface is clear inadequately, and this is that the defective of shower nozzle technology causes, and is bigger to the meticulous style influence of printing high-grade fabric.
2, fault is many.Because wax spray equipment adopts many shower nozzles, and the solid wax that adopts hot melt is as atomizing of liquids, the aperture of spray orifice minimum again (≤0.05mm), so be easy to cause spray orifice to stop up, this kind equipment stops up because of spray orifice, maintenance difficult is stopped using mostly.
3, cost is very high.The company that the used black solid wax stone of wax spray system net is a shower nozzle produced in USA produces without competition, and this wax stone can not reclaim again, only this item, and every cylinder will increase more than 50 yuan of expense.
4, the system net time does not shorten.In fact, wax spray system net has only saved colour separation film making (but having brought serious distortion), and other production process do not save.Still need expose after the wax spray, develop, all processes such as drying, colour-separation drafting, polymerization, also to increase the dewax operation, so speed is still very slow.
The purpose of this invention is to provide the laser under a kind of control that can utilize computer, the computer color splitting graph text information is directly exported to the system network technology that scribbles on the screen cloth that solidifies glue.
Making net by laser method of the present invention, especially the preparation method of stamp half tone also comprises following making step: the former state (2) that (1) prepares the stamp pattern is prepared net embryo (4) at computer prepackage stamp spot color separating system and style (3) and be coated with the curing glue of can vaporizing on screen cloth; (5) divide colored pattern laser-induced thermal etching (5.1) that screen cloth is stretched on the air pressure capsule that the surface is covered with thin metal layer; (5.2) generating device of laser is contained in can with the high-precision servo actuator of half tone relative displacement on; (5.3) described generating device of laser Stimulated Light switch control, described computer is controlled described laser switch by drive circuit; (5.4) sensor of described high-precision servo actuator sends position signalling continuously to computer, computer instructs high-frequency etching laser beam on the formation time order of described laser switch switching laser beam according to position signalling, with the vaporization of the curing glue on the half tone predetermined point, etch the stamp style; (5.5) ventilation smoke abatement device will be vaporized outside the glue smog discharge machine.(6) check half tone (7) upper baffle that makes

Advantage of the present invention is:
1, reduces system net operation, shorten the system net time
From above-mentioned system net flow process as can be seen, in the tradition system net, only the preparation of black and white original text will have been spent a lot of times, even the black and white film of modern laser photocomposing machine output, also need through edge sealing, hack, beat work such as rule, bag sheet, matte, careless slightly, will make mistakes, even slice, thin piece or half tone are scrapped.Secondly, tradition system net is even current wax spray system net also all has technical process such as exposure, development, low temperature drying, to 64
*The cylinder of 180cm from drawing lay marks, needs more than five hours to finished product flower net, and making net by laser then once replaces with laser vaporization, only needs 18 minutes.It is very favourable that this adds system to scoring a goal of online production.In the past; generally speaking; changing on the new variety machine from the style that scores a goal starts to print and needs more than two hours; sometimes again may be unripe because of the mill base of next style, and stop the longer time, shutdown loss is very big; as long as then wait a moment now; new net just can make, and therefore, can significantly reduce the loss of downtime and mill base.
2, increase substantially system net quality, guaranteed the reappearance of system net
The colored net quality that making net by laser is made is better than conventional method, is mainly reflected in following five aspects:
1. eliminated bag sheet error
Be unable to do without colour separation film in the tradition system network process, before address, this colour separation film temperature influence is easy to generate flexible, in fragmented packets sheet process, very easily produce butt joint and stitching error again, in fact in, in the fragmented packets sheet of small pieces, because of well-behaved error must cause accumulated error, this error, even it also is inevitable using the view picture sheet, bag sheet error causes the registering error, connects an edition error, causes silk fabric face secondary color irregular or show money or valuables one carries unintentionally, and influences outward appearance even causes substandard products, making net by laser has been got rid of film, so there is not bag sheet error.
2. eliminated exposure error
Tradition system net is controlled the time for exposure with empirical value, by the operator determine voluntarily (because of the people, because of board different) exposure frequency (being the time), be easy to generate under-exposure or excessive, cause the color separation figure on the film that greater loss is often arranged, simultaneously, the blackness of black and white film and transparency also can not be in full accord, and as if exposing with the same time, effect is inevitable different like this.This exposure method reappearance is also poor, and making net by laser does not have exposure process, thereby does not have exposure error.
3. eliminated the development error
Tradition system net must develop after exposure, and developing method is more original, water dashes, and scrubs with hairbrush, and cylinder inside glue-line is netted tube friction solution back and forth on sponge by manually spurring, development effect is range estimation by rule of thumb entirely, shortage science detection means has very big randomness, varies with each individual, uniformity, the definition of developing can't guarantee that all reappearance is poorer certainly.Making net by laser does not have developing process, and the development error is surely not arranged.
4. eliminated color separation graph text information data degradation
Tradition system net transmits color separation information with black and white film, and data degradation is more, and making net by laser is directly transferred to the color separation graph text information on the net base by computer, so can reproduce original copy spirit, makes the figure line meticulousr true to nature.
5. improved the half tone fastness
Owing to got rid of processes such as exposure in traditional system net, development, photoresists are solidified fully, simultaneously, because laser vaporization, penetration capacity is strong, and has the function of selective evaporation, and this can improve the curing fastness on the one hand, can guarantee not damage the net base on the other hand again, so the half tone fastness improves greatly.
3, improve system net working condition
Tradition system net must carry out in the darkroom, under red light, hack, beat rule, bag sheet, vision impairment is very big, simultaneously in order to prevent that black and white original text sheet is clamminess, causes the sensitization failure, so all adopt the constant temperature and humidity measure, so just cause operationlocation's improper ventilation, the air muddiness, and making net by laser all can be operated in the open, does not have this drawback; Secondly, traditional exposure light source all is a ultraviolet light, and this light is harmful, and it is bigger to be engaged in this work harm for a long time, and what use during making net by laser is laser beam, is not again direct irradiation, to human body without any influence.
4, reduce sewage discharge, the favourable ecological balance
Tradition system net consumes a large amount of clear water when developing, contain noxious materials such as chromium in waste water, contaminated environment, and directly the photoresists vaporization is decomposed during making net by laser, through measures such as activated carbon filtrations, no waste water, waste steam exhausting are so can improve the ecological environment greatly.
5, reduce cost, raise the efficiency
Remove film from, only film is made every net and is saved cost 50-100 unit;
Tradition system net generally needs two people's compounding practices (one class of three people of factory that have); 10 efficient of per tour system net have been calculated well; and the employing making net by laser; a people can operate; per tour can be made more than 10, and as water rate, sewage disposal expense, air-conditioning expense, darkroom lighting expense, the exposure electricity charge etc. are counted, cost can reduce by more than 50; if the shutdown loss during the benefit net counts, economic benefit is more considerable.
