Description
Technical field:
The production technology that the present invention relates to the imitative large jacquard weave textile composite fabric of a kind of laser, it belongs to textile processing technical field, particularly textile printing and dyeing industry environment-friendly type anhydrous printing production technical field.
Background technology:
The explanation of proper noun:
Whiteness W:W is writing a Chinese character in simplified form of White.
As shown in Figures 2 and 3, in the time that W value is zero, the white lines of pattern and region be any etching of Stimulated Light not; When W value is 100%, the white lines of pattern and region can be subject to the etching of ceiling capacity laser; It should be noted that, in the time that laser energy is maximum, also can increase laser ablation degree by the production linear speed that reduces continuous dynamic type laser, can certainly reduce laser ablation degree by the production linear speed that improves continuous dynamic type laser simultaneously.
Blackness B:B is writing a Chinese character in simplified form of Black.
As shown in Figures 2 and 3: in the time that B value is zero, the black lines of pattern and region be any etching of Stimulated Light not; When B value is 100%, the black lines of pattern and region can be subject to the etching of ceiling capacity laser; It should be noted that, in the time that laser energy is maximum, also can increase laser ablation degree by the production linear speed that reduces continuous dynamic type laser, can certainly reduce laser ablation degree by the production linear speed that improves continuous dynamic type laser simultaneously.
Etching effect:
If Fig. 4 is for having grey gradual change lines and region class pattern, Fig. 5 is that the gray scale of the pattern in corresponding diagram 4 is adjusted conic section, and in Fig. 5, R, L, P, C, Q are respectively gray scale and adjust from left to right the sort empirical value scope of corresponding R, L, P, C and five sections of region curve capable of regulating gray scale amplitudes of Q of conic section.It should be noted that, these 5 empirical values of R, L, P, C and Q cannot be zero simultaneously; In the time that laser energy is maximum, also can increase laser ablation degree by the production linear speed that reduces continuous dynamic type laser simultaneously, can certainly reduce laser ablation degree by the production linear speed that improves continuous dynamic type laser.
Clothing fabric is by dyeing and printing technology arrangement, can obtain good effect and the aesthetic effect taken.Traditional clothing fabric with art pattern, is mainly by multiple dyeing and printing process technology, makes different dyestuffs by flower version painted formation pattern on the fiber of fabric.In addition, also have by other chemical methodes or by the method for hot transfer printing, digital spray printing and form clothing fabric design.But a large amount of or the traditional stamp mode of weaving face fabric, the technological process of production is longer, pattern is single, variation program complexity, and production process relates to the restriction of environmental protection aspect more, particularly can not realize the growing demand for the personalized artistic effect of clothing fabric of people.Utilize laser technology, textiles and garment material are carried out to artistic finishing, produce stamp special effect, there is important promotional value.It is the same with hot transfer technique, digital printing technology; it is all non-water energy-saving printing technique; became in recent years the water-free dyeing technology that can meet environmental requirement and can embody again textile fabric design, and be one of direction of industry sustainable development, thereby be significant aspect environmental protection.
Laser technology existing application in the many technical process of textile industry at home and abroad (as: cutting, sewing, distortion, modification, singe, fixation, false proof and bleaching etc.).Be used for greatly at present preparing printing screen artistic carving and utilize laser technology to carry out anhydrous " wash water " effect process to textile jeans.Along with CAD and graphics and the infiltration of industrial automation subject crossing, expand laser engraving range of application, laser science and technology and Art Imagination power, install in respect of effect combination with traditional fabric design kimonos, for laser carving technology provides new approaches in textile field application.
The colored type design of 3D galvanometer cowboy laser spraying decoration laser engraving machine, parameter are selected to be able to very much at present perfect with manufacturing technology, and apparel industry has had many products to adopt 3D galvanometer cowboy laser spraying decoration laser-engraving technique to process, the science and technology strength of laser element is ideally incorporated among the design of Fashion trend.
The feature of textiles laser carving:
Morphological feature, chemical constitution and the selective absorbability to laser based on textiles with organic material, textiles Laser Processing is different from the fuel factor in metallic article Laser Processing, and the physics and chemistry such as metamorphosis and chemical bond rupture effect also occurs.Due to the kind difference of textile fabric, the thickness difference of yarn, the institutional framework difference of textiles, and the otherness of all kinds of coatings and composite material Facing material, its fuel factor, physics and chemistry effect are not identical, make the effect of laser carving processing different yet.
But the deficiency that the application of current laser technology on weaving face fabric exists is mainly as follows with developing direction from now on:
L, how to improve dynamic continous mode production efficiency to meet the demand of large-scale production;
2, how to solve the problem of etching carving dull coloring;
3, how to control minimizing polyester-cotton blend woven fabric and fall strong loss problem;
4, except jean, the application study of other unlike material and serial textile composite fabric.
In order to address the above problem, utilize galvanometer focusing technology and high-power (one kilowatt of laser power) and the movement at the uniform velocity of whole breadth of the current dynamic continous mode laser carving machine of environment-friendly type open width, and be no longer x, y axle moves, make the engraving of breadth very even, can solve in theory the inside and outside engraving that popular laser engraving machine cann't be solved at present inhomogeneous, production efficiency is low, the restricted a large amount of problems that wait mass production to exist of engraving fabric width, be expected to reach per minute more than 4 meters for realizing the continuous speed of production of engraving, fabric width can reach 1.8 meters, provide strong technical support for realizing water-free dyeing.
At present laser carving technique is mainly used in carving on textile jean, substitutes in the special effect stamps such as washing bleaching and arrangement in textile garment industry, and application on polyester-cotton fabric is less.Be mainly because contain terylene composition in polyester-cotton fabric, polyster fibre is after laser treatment, and the fuel factor of laser causes the powerful decline of dacron very fast, and easily causes contraction.From pertinent literature, laser is less to the damage of jean cloth, falls strong rate and remain in 30% after engraving; Laser is comparatively serious to the damage of polyester-cotton blend denim, and after engraving, especially broadwise is fallen strong rate and sometimes remained on 60% with interior all difficult.
