Description
Technical field
The present invention relates to a kind of printing method, especially on weaving face fabric, carry out the method for laser decoration printing.
Background technology
Along with the continuous progress of science and technology, the appearance effect of stamp weaving face fabric is rich and varied further.But the decalcomania of existing weaving face fabric, its printing method all are to adopt conventional printing roller or stamp web plate, and gradation forms pattern after stamping the dyestuff of different color; Dyeing process complexity not only, yield rate is not high, and production cost is difficult to reduce; And decalcomania is accurately attractive in appearance inadequately, and pattern transfer is comparatively complicated, can not satisfy market demand.Simultaneously, on dyed shell fabrics, produce the flower type, must be through dyeing process and two processing routes of revenue stamp process.
Along with the maturation gradually of laser technology, the application of laser technology in the conventional art field is more and more general.Because the product that utilizes laser technology to produce is more accurate more attractive in appearance, can greatly improve the added value of product and the performance of enterprises, so branch of industry adopts laser technology more positive.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes the above-mentioned background technology, by laser scanning, and dyeing again, a kind of method of patterning that produces on weaving face fabric is provided, this method should have that production process is simple, changing patterns is easy, and production cost is low, the characteristics of energy-conserving and environment-protective.
The invention provides following technical scheme:
A kind of laser decoration printing method of weaving face fabric, carry out successively according to the following steps:
One, lining is flattened on workbench;
Two, with required pattern scanning input laser equipment;
Three, start laser equipment, laser wave that laser head sends is scanned along the width or the length direction reciprocating motion of lining;
Four, the lining of finishing laser scanning enters the normal dyeing operation.
When the distance of laser head and lining is 15---200mm; The sweep speed of laser head is 20---500mm/s; The scan power of laser head is 5--120 watt.
Preferred lining is a chemical fiber plus material.
The printing method that the present invention adopts has not only changed the configuration of surface and the structure of face liber, and face liber has been carried out the modification of surface light chemical reaction owing to utilize laser that chemical fiber plus material is carried out radiation scanning in advance; Then the absorption property of reflection of light and dyestuff has all been produced obvious variation by the position of radiation post-modification on the lining; Therefore, on lining, carry out local laser emission regularly, just can form required pattern by conventional dyeing again on the lining surface.In addition, utilize laser that the part of lining is heat-treated, the micro-structural (localized heat setting) that changes local fiber changes dyeability or shrinkage, also has tangible printing quality.This just makes revenue stamp process become simpler, and the decalcomania of being produced is more accurately attractive in appearance, and production cost is minimized; And because decalcomania adopts Computer Processing, the switching of different pattern alternates and becomes very simple, and the pattern content is more rich and varied, is subjected to the popular welcome in market.

The specific embodiment
The present invention utilizes the laser emission weaving face fabric; Because laser energy concentrates (aggregation) can quicken to heat lining, and high directivity, controls area heated easily, also adopt computer control easily.Concrete thinking is to adopt the high frequency lasers generator, decalcomania digital information control laser dotting by Computer Processing, by the translation of laser head finish pictorial information through the broadwise scanning motion, realize the dot matrix reduction of decalcomania digital information on cloth cover, make required decorative pattern and pattern.And the pattern of liking (or photo) be selected or be provided to concrete pattern can by the user, then this pattern is imported computer (also can take back input computer with digital camera) with scanner, in computer, these patterns are edited, can add literal, background or modification, with in the pattern input laser equipment that edits, after laser scanning, promptly obtain pattern again.
Therefore, the laser decoration printing method of this kind weaving face fabric needs to carry out according to the following steps successively:
One, lining is flattened on workbench;
Two, with required pattern scanning input laser equipment;
Three, start laser equipment, make width or the length direction scanning of laser wave that laser head sends along lining;
Four, the lining of finishing laser scanning enters the normal dyeing operation.
Because chemical fiber plus material non-high-temperature resistant material, be easy to by high-temperature damage even be damaged, so the energy of laser emission should be controlled at certain limit; And the distance dependent of laser emission energy and laser scanning speed, laser radiation power and laser head and lining, this three is closely related again; General, when the distance of laser head and lining when 15--200mm (laser head in the general laser equipment has automatic adjusting height function, so as long as by corresponding automatic adjusting key), laser scanning speed is in the 20--500mm/s scope; The scan power of laser head can be between 5--120 watt (adjustable range 1%--100%).
Specific embodiment:
The laser decoration printing equipment that adopts in the present embodiment mainly is laser engraving machine, computer; Aspect dyeing, mainly contain infrared dyeing machine, setting machine, water-bath etc.
Laser equipment uses step:
Opening power is confirmed the startup action of laser instrument start;
The select File pattern.Start button is put Start under the monofile pattern; Under the multifile pattern, start button is put Stop;
Put into working substance;
Focusing (regulating the distance of laser head and lining) can be selected focusing or manual focus automatically;
Open ventilation equipment, open air compressor, and adjust suitable tolerance;
The file that edits is downloaded to laser instrument by computer;
Start working, can do emulation earlier in case of necessity, open loam cake, observe the file domain of walk of ruddiness indication;
Behind the end-of-job, take out working substance, after the cleaning, close opening device, powered-down.The laser equipment property regulation:
Laser equipment is regulated and is divided dual mode, and a kind of is the adjusting of laser scanning speed, and a kind of is the adjusting of laser emission energy.And the adjusting of this dual mode all is to finish by software on the computer that links with it.Shown on computers mode is " SPEED " laser scanning speed, and adjustable parameter is 1%～100% (sweep speed is 50% o'clock, and it is real-valued to be 250mm/s); The size of " POWER " laser emission energy, adjustable parameter are 1%～100% (5--120 watt).
In order to improve the definition of decalcomania, also can further handle the pattern that laser equipment is imported.
Laser equipment is to carry out according to the gray scale of input picture to the processing of input pattern, and it can regulate the emittance size automatically according to picture gray scale size, and the energy size that we preset is applicable to black colourity; So pattern should be handled by special-purpose software before the input laser equipment.
At first, the colour contrast of patterned background and prospect should be tried one's best greatly, because contrast helps us greatly image is handled, and special-purpose imgae processing software CORELDRAW mainly is by removing colour, contrast, brightness, the intensity of the image of adjusting show the variation by shade of foreground and background colour significantly.
The general step that pattern is handled is:
1, opens CORELDRAW, set up the file of a blank, import the pattern of the stamp of wanting then;
2, the cancellation of click " effect " the inside is saturated;
3, cancellation saturated after, pattern seems point fuzziness, we meet the requirements up to clear patterns by suitably adjusting brightness, contrast and the intensity of pattern.
By above processing, some significant variations can take place in pattern; Fig. 3 and Fig. 4 are respectively patterns before and after handling.
