Summary of the invention
The object of the present invention is to provide a kind of laser treatment of utilizing on textiles, to generate method of patterning, directly shine on the material, omit dyeing process in weaving, and the sense that has levels of the contrast effect of pattern, can Continuous Selection from 0-100%.
Another object of the present invention is to provide a kind of laser treatment of utilizing to generate method of patterning on textiles, the speed and the energy of laser beam are adjustable.
An also purpose of the present invention is to provide a kind of laser treatment of utilizing to generate method of patterning on textiles, laser beam according to after the society burn degree and burning degree is controlled.
For achieving the above object, the invention provides a kind of laser treatment of utilizing and on textiles, generate method of patterning, comprise the steps:
Layout is input in the computer system,
With described computer system control laser marking/diced system;
With the laser beam irradiation one weaving material that described laser marking/diced system generates, described laser beam generates described pattern according to described layout on described material;
The contrast effect of described pattern is regulated and control by described laser marking/diced system.
Convert the figure that generates by described pattern in the described computer system to corresponding simulate signal or data signal, perhaps simulate signal and data signal, to move the direction of motion and the speed of described laser beam.
Described laser marking/diced system has scanning system that is driven by described analog signal or the stepper motor/servomotor workbench that is driven by described data signal; When carrying out the described pattern of laser beam engraving/cutting, both work also capable of being combined that can work independently.
The contrast effect of described pattern is that the described textile surfaces of logical change is burnt degree or burning degree control.
The described textile surfaces degree of burning is to regulate with the size of the speed of light beam movement velocity and light velocity energy.
Described textile surfaces burning degree is to control by gas jet or liquid on the surface of laser beam irradiation.
When utilizing the described pattern of laser beam engraving/cutting, described material surface utilize nitrogen as fire-retardant gas or adopt water as fire retardant.
The cutting shoulder of described weaving material is along leaving harder burnt limit.
The cutting shoulder of described weaving material is along being suitable sliding cutting mouth.
Contrast pattern on the described weaving material be by described laser beam irradiation back form burn vestige or the degree of burning forms.
Effect of the present invention and advantage are fairly obvious: operation is simple, the deep or light contrast effect of color and luster light and shade is adjusted in advance, make the generation pattern well arranged, and can on material, generate the pattern of the desirable color different, thereby make pattern conform with the aesthetic of people more with the original color of material.
The specific embodiment
Below by accompanying drawing and preferred embodiment the present invention is described in further details:
At first, because the present invention does not have too many requirement to the weaving material, the material of no matter weaving is dark, light, and still white, colored can generate layout, thus design a kind of pattern, and prepare the weaving material.
The second, layout input computer system, in computer, utilize software processing system, described pattern data is converted to two kinds of signals: analog signal and pulse digital signal, with standby, see Fig. 1.
Analog signal is used to drive the scanning system of XY diaxon.
Pulse digital signal is used to drive the stepper motor or the servomotor workbench of XY diaxon.
The 3rd, prepare laser system, below two kinds of instruments all can (alternative or all select): see Fig. 2 A and Fig. 2 B.
1,50WATT carbon dioxide laser scanning mark machine.
2,100WATT carbon dioxide mark diced system.
The 4th, the movement velocity of control laser system and laser energy change the degree of burning of textile fabric.
For first kind of laser instrument, adopt 40 watts of laser powers, spot motion speed 100mm/ carves second; Adopt 48 watts of laser powers, spot motion speed 20mm/ cuts second.Spot diameter all selects 0.25mm.
For second kind of laser instrument, adopt 10 watts of laser powers, spot motion speed 200mm/ carves second; Adopt 80 watts of laser powers, spot motion speed 60mm/ cuts second.Spot diameter all selects 0.13mm.
The 5th, gas jet (N2) or liquid (water) control burning degree on the light beam irradiates surface of control laser system.
The 6th, the contrast that forms on the textile fabric can be 0-100%.So-called 0 is no contrast, promptly do not shine, so-called 100% is hollow out, and promptly the illuminated part of article is all burnt, middle for what can control continuously, utilize the emitted dose of the direction of motion, energy size and the gas/liquid of above-mentioned method control laser beam to realize.
And, selecting contrast 100%, burn degree by change, when promptly adopting the control of movement velocity and energy, cutting shoulder stays bigger burnt limit along meeting, and it is harder than textiles itself welding (Re-melting) phenomenon to occur turning over, and the sensation of needle-holding hand is arranged.And by adding fire-retardant thing, the control burning degree, promptly when gas jet or liquid, Jiao Bianhui significantly reduces, and otch the welding phenomenon can not occur turning over along sliding.
Utilize said method and step, on common dark textiles, burn part and can form lighter brown.For light color or white textiles, burn part and can form darker brown, thereby make pattern form tangible contrast pattern.See Fig. 3.
Following mask body is in conjunction with the accompanying drawings in that the present invention will be further described:
In Fig. 1, job step of the present invention is as follows:
Step 10 is imported computer system with layout;
Step 11 is handled by software and is made figure convert the analog or digital signal to;
Step 12 is placed on textiles under laser scanning mark machine or the mark diced system;
Step 13 laser beam is radiated on the textiles, is sprayed fire-retardant thing according to part with the control burning degree at textiles simultaneously;
Step 14 textiles stays focal spot or otch after the laser beam irradiation, demonstrate former layout.
Among Fig. 2 A, a kind of CO
2Laser instrument (22) drives X scanner (20) and Y scanner by laser focusing system (21), laser scanning printer (23) is gone up at textiles (25) generated pattern.
Among Fig. 2 B, another kind of CO
2Laser instrument (22) drives the step motion motor by speculum (27) and moves on the X Y-axis, and laser is gone up at textiles (29) by crescent moon focus lamp (28) and generated pattern.
Fig. 3 utilizes laser treatment and the pattern effect that generates, is layout with printed words such as " happiness as boundless as the eastern seas ", and after laser marking was handled, " good fortune " word pattern contrast effect of falling was well arranged, and " east " word pattern then is the effect of hollow out.As seen, pattern contrast effect of the present invention can arbitrarily be regulated and control.
