The method of applying a printed image to woven material

 

The invention relates to light industry and provides a stable image on all types of fabrics. When applying the printed image on the woven material as a woven material using an organic material. Preliminary treatment is carried out by immersing the material in a pre-heated alkaline solution for stretching the membrane surface of cells of woven material and accelerate the reaction of the interaction of the latter with the specified solution at elevated ambient pressure bearing of the additive components for fast drying pigment, and getting soaked in an alkaline solution of woven material. Next, the impregnated material is subjected to a preliminary extraction to the state of the cessation of runoff solution. The material is then subjected to a final extraction under the action of mechanical pressure in the presence of high temperature, resulting in getting dried and aligned cloth woven material. Before fixing the image on the woven material of the latter is placed in a water steam zone or in the electromagnetic field for the bonding of the pigment with a woven material, and keep it asadero pigment on the woven material is carried out by immersing the woven material coupled with the pigment in the acid environment for neutralization, further extraction and washing in water. 15 C.p. f-crystals, 3 ill.

The invention relates to light industry, and more specifically to a method of applying a printed image to woven material.

Now the actual problem drawing on natural woven material exclusive images limited by the size of the canvas area of 1 square millimeter, and the application of exclusive images in production volume at the request of the consumer while preserving the environment, reducing the production areas for equipment that is involved in applying the printed image. In addition, there is the problem of placing equipment for printing on woven material in the room closest to the consumer. In addition to the above, still unable to obtain reliable photographic image on woven cloth.

Widespread at this time, the application technology of the printed image on the woven material designed for drawing the same image on a large area of woven fabric due to the ineffectiveness of having equipment for applying exclusive images on a small number of areas. the, swesty from the patent RU 2002870 C1. The known method involves feeding woven material in a printing device, forming on the material image and the subsequent exit of the printing device. As of the printing device applied to an inkjet printer, which is the application of pigment in the form of elements forming the image. These elements in the form of droplets forms electrocapillary printer head through the nozzle which is the pigment.

The above method creates an image fast, high brightness, contrast and color intensity and is widely used for printing the image on paper. When drawing on woven natural material above described manner, the resulting image appears to be weak to physical and chemical effects on him, namely, when the image is affected by UV rays it will fade when exposed to water, it dissolves, by mechanical action, it is erased, when exposed to solutions of acids and alkalis, it will practically dissolve or rasplyvetsya respectively. Based on the above-described method has not found wide application in the textile industry is enta US 4702742. The known method is that the woven material is subjected to preliminary processing, which receive the cloth, adapted for submission to the printer. As the woven material can be applied to synthetic and/or semisynthetic material. In the pre-treatment on woven synthetic or semi-synthetic material is applied, the suspension is formed from a film-forming substance, a binder and fixer. In the film-forming composition is included as a component of formaldehyde. Then perform the alignment and indentation of the suspension in the woven material and its subsequent drying, resulting on the surface of the woven material was obtained film designed for application in the next of the image. Following this, the fabric coated with the film served in a device for stretching and smoothing the sides for submission to the printer.

Pre-treated synthetic and/or semisynthetic material served in the printing device, where the application of a pigment in the form of elements forming the image on the film. As of the printing device applied special TDE grains. Because of the presence in the textile pigment of various salts of the printhead nozzles perform large, which leads to the blurring of lines, low sharpness and contrast of the images, and also applied pigment does not inherently bright, vivid images, resistant to all types of physical and chemical effects. Following this, the obtained woven material image is subjected to fixing, namely, the subject material is coated on the film image is heat-treated at a temperature of more than 100oWith removal of the water contained in Crusader pigment, and strengthening the links between the pigment, a film and a woven material. However, not all types of woven material can withstand the above-mentioned heat treatment, such as wool, silk, viscose.

The image obtained above in a known manner, is not resistant to wet and dry rubbing, multiple washings, mercerizing, to ultraviolet radiation, to hypochlorite and peroxide abelcam, the impossibility of forming a crease-resistant fabrics in the manufacturing process without significant changes in hue and intensity loss of color. In addition, the fabric caused so picture the lei, the inability to reproduce the printed image on such kinds of woven material such as silk, wool, viscose, and also increases the cost of the final product due to the manufacturing of special print heads, cartridges, systems supply pigment ink tank to the printhead.

The closest technical solution according to the essential features and the achieved result is a way of drawing on woven material, is known from the patent EP 1010802, the known method is that the conduct preliminary processing of woven material, as a result fabric, adapted for submission to the printer. The specified pre-processing is to ensure that the textile fabric is applied a first coat with the help of rollers. As a woven material using an organic material. Then submit pre-treated woven material in a printing device of the piezoelectric printer, the print head is covered with a special material from a number of titanium, gold, etc. to give the material to the head of repellents with respect to the ink, where the application of a pigment in the form of the element is between the steam zone for fixing the dye on the fabric material. However, the implementation of the method described above requires a large capital costs due to expensive printing equipment and the need for large production areas. This led to the fact that the above method is not propagated.

The basis of the invention is to create a method of applying a printed image to woven material, in which by changing the phases of the method would provide printing on virtually all types of fabrics from natural fibers used for clothing and other products, would require small production area and low material costs.

The problem is solved in that in the method of applying a printed image to woven material, involving pre-treatment of woven material, as a result fabric, adapted for submission to the printing device, as a woven material using an organic material, the feed pretreated woven material in the printer type of the printer, where the application of a pigment in the form of elements forming the image, and then woven material with the received image is placed in the steam zone, and then obtained is carried out by immersing the material in a pre-heated alkaline solution for stretching the surface membranes of cells of woven material and accelerate the reaction of the interaction of the latter with the specified solution at high pressure environment bearing additive components for fast drying pigment, and getting soaked in an alkaline solution of woven material, then the impregnated material is subjected to a preliminary extraction to the state of the cessation of runoff solution, then the material is subjected to final extraction under the action of mechanical pressure in the presence of high temperature, resulting in getting dried and aligned cloth woven material, as well as the location of woven material with printed image in a water steam zone or electromagnetic field is carried out before fixing the image on the woven material for the bonding of the pigment with a woven material and hold it until while visually will become apparent adhesion pigment with a woven material, and fixation is carried out by immersing the woven material coupled with the pigment in the acid environment for neutralization, further squeezing and rinsing in water.

This implementation of the method according to the invention provides the image on natural woven material by giving the original canvas properties "paper" with a good adhesion of the dye is Oia, used for processing of woven material and fixing the images on it, and low capital costs due to the low cost of production, printing equipment.

Canvas with properties "paper" is an intermediate product in the method according to the invention represents an aligned, dried leaf, which can be used as a starting product other textile companies for printing the image on it with your own dyes and art workshops for use as the basis for drawing the image with oil, batik, watercolor, gouache, pastel, printing for printing the image copying machines.

Thanks to the method according to the invention, receive a multi-color image in a single pass of the fabric through the printer.

Recommended as a organic woven material to use protein and/or vegetable material.

Preferably as protein woven material using a material selected from a range of natural silk, wool, and as the plant material using a material selected from a range of cotton, linen, viscose. The use of protein and raises the Alov to stretch to absorb pigments, resistant to acids and alkalis, temperatures above 100oC.

It is recommended that the pre-treatment material had a surface density in the range from 1 to 350 g/sq. m, with a thickness from 1.0 to 650 μm, fracture resistance of not less than 9000 kinks. Giving material above characteristics can be used in all types of printers, which simplifies and cheapens the process of drawing the image.

You need to maintain the temperature in a water steam zone from 100 to 140oC. When the temperature in the storage area below the 100oC will not occur clutch pigment with an alkaline solution and fiber woven material. In addition, the saturation of the color gamut of the image on natural woven material will be very low. At temperatures above 140oC increases the rate of penetration of the coloring pigment in fiber woven material, which leads to blurring of the image on the woven material.

It is desirable that when the final pressing of the material under the action of mechanical pressure high temperature was in the range from about 50 to about 350oC.

Specified Tory, and vegetable woven material greater. At temperatures below the 50oC will not occur alignment material from plant fibers and blended with vegetable fibers. And at temperatures above 350oC is the charring fibers woven material.

Can the alkaline solution is pre-heated in the temperature range from about 40 to about 150oC.

Pre-heating the alkaline solution required to mitigate her actions as alkali into fibers by activating other components of the solution. When removing the woven material from a solution at room temperature, the action of alkali on the fiber increases by swelling of the latter.

It is advisable that the alkaline solution contained components ammonium sulfate, sodium nitrite, sodium carbonate, thiodiglycol, urea, adhesive binder, solutionyou salt, caustic soda, sodium bicarbonate, glycerin, table or Glauber's salt, taken in the following weight ratio in g on 1 l of water: ammonium Sulphate - 10-50 sodium Nitrate - 5-30 sodium Carbonate - 0-2 Thiodiglycol - 25-100 Urea - 10-150 Adhesive binder - 10-100 Caustic soda (32,5%) - 10-50 sodium Bicarbonate - 10-50 Glycerin - 0-100
Soluziona salt - 15-100
Sodium chloride or Glauber is the group of when in the steam zone, is the transformation of the pigment from the water-insoluble state to a water-soluble state, which is unstable under the influence of air, acid fumes in the shop, the sun's rays. To improve the stability of the water-soluble pigment in an alkaline solution introduced sodium carbonate, thiodiglycol, urea. Such a composition of the alkaline solution, in the material, further speeds up the process of diffusion of the applied pigment inside fiber woven material due to chemical interaction of the components of the pigment components of the specified solution. In addition, the above composition of the alkaline solution improves the intensity of the color, brightness, saturation, colors all colors pigment, such as thiodiglycol and urea increases the resistance of the red color in the processing of tissue at temperatures close to the boiling point; ammonium sulfate and sodium nitrite promotes firmness, brightness and saturation of the primary colors of pigment. When applying pigment into thin silk, such as chiffon or wool presence in an alkaline solution of sodium carbonate, and prisutstvie in an alkaline solution of sodium carbonate and glycerol is desirable to obtain reliable photographic image. The presence soluzioni salt in alkaline solution increases the fluidity of the pigment. Introduction in an alkaline solution of sodium chloride or Glauber's salt prevents diffusion of pigment into the specified alkali solution, resulting in a savings solution and the possibility of its use in subsequent batches of woven material.

Preferably the adhesive binder to choose from a number of starch, tragant or their mixture, and the mixture of dextrin, carboxymethyl cellulose in the form of sodium salt, sodium alginate.

The above series of adhesive binder soluble in water, and provides a clear outline of the pattern on the woven material. In addition, in the processing of woven material with adhesive connecting the latter dissolves in the acid solution, while the pigment is transferred into an insoluble state on the fiber woven material.

Preferably, when vegetable woven material after fixing the printed image is dipped in a 2% solution of oleic soap at a temperature close to the temperature of its boiling point, and incubated for 0.5-2 minutes This reception method is required to neutralize the action of sulphuric acid on the fiber woven material and save the flax, when the protein woven material after fixing the printed image is immersed in 15% acetic acid solution at room temperature.

Above the reception leads to neutralize acidic medium in the woven material, to increase the durability of the latter, the stability of the printed image to a high temperature wet treatment of various washing detergent powders.

It is recommended that the acid medium containing components: sulfuric acid, urea, sodium nitrite, ammonium sulphate, hydrogen peroxide, taken in the following weight ratio in g on 1 l of water:
Sulfuric acid 96% - 5-30
Urea - 2-5
Sodium nitrite - 2-3
The ammonium sulfate - 5-20
The peroxide - 10-42
Urea in the solution is required to partially prevent the release of nitrate compounds. Sodium nitrite and ammonium sulfate are required in the solution to increase the brightness, the saturation of the printed image. Hydrogen peroxide is the oxidizing agent, acting on pigment further its transition from a state, soluble in water, in a state that is insoluble in water.

Preferably, when the temperature of the acidic environment from about 50 to about 80oWith time federiciano 50oWith the exposure time of woven material in an acid environment ranged from 15 to 30 minutes

This temperature interval and the exposure time in the acid solution of woven material with printed image is the most optimal for the oxidation process and start fixing the pigment to the fiber. At temperatures below the 50oWith a significantly reduced amount of hydrogen in solution, leading to poor consolidation of the pigment to the fiber. At temperatures above 80oWith fiber woven material are destroyed. If the exposure time of woven fabric in the specified optimum range to choose less than 0.3 min, the effect of secreted hydrogen pigment is insufficient to secure the latter. If the exposure time to choose more than two minutes, it will lead to the destruction of the fibers of the woven material. Maintaining in an acid medium temperature range from about 50 to about 80oWith suitable for fixing the pigment on a base of woven materials made of vegetable fibers. Maintaining in an acid medium temperature range from about 40 to about 50oWith suitable for fixing the pigment on a base of woven materials from protein fibres. When temperature is initiated pigment to the fiber. At temperatures above the 50oWith will be an intensive process of selection caustic vapors, which creates problems of health service staff. If the exposure time of woven fabric in the specified optimum range to choose less than 15 min, the effect of secreted hydrogen pigment is insufficient to secure the latter. If the exposure time to choose more than 30 min, it will lead to the destruction of the fibers of the woven material.
