The present invention relates to light industry, and more specifically to a method of pre-processing of organic woven material for drawing the image.

Now the actual problem harvesting of organic woven material, adapted for direct application of the coloring pigment in the form of an image by the printing device, and by means of known technologies, such as drawing oil, batik, watercolor, gouache, pastel.

Currently known for the procurement of organic material coated with an adhesive paper basis for applying the image printing device.

However, they require large capital cost of building the device, providing the workpiece in the printing device, as well as developing special printing devices that require special textile ink, special ink cartridges, ink, etc. But so far failed to create a method of pre-processing of organic woven material providing osobenno for drawing the image in printing devices such as inkjet, laser, led, - color, dye-sublimation printer.

The closest technical solution according to the essential features and the achieved result is a method of pre-processing of organic woven material for the printer type inkjet plotter, known from the article "Preparation of cloth for printing the active and acidic ink", published in the journal "SIGN master" N 1 from 2001, pp. 26-27, put in a set of 21 March 2001, was signed on 2 April 2001.

The known method is that the organic woven material is dipped in a special solution, the composition of which depends on the type of fabric, impregnated her solution to wetting, such as 70%, then impregnated with a solution of woven material is subjected to extraction and subsequent drying, resulting in getting dried and aligned cloth woven material, which is put on self-adhesive paper basis to prevent distortions of the material upon application to the printing device, such as a plotter. Woven, printed on clausula base paper, is a workpiece for applying a printed image. In the above-described method applied to the solution, which cm weight ratio, g on 1 l of water:

urea - 100

sodium alginate - 100

sodium carbonate - 40-0

sodium bicarbonate - 0-40

The ratio of the above components can be seen that the workpiece woven material is soft, porous, highly deformable upon application to the printing device, which led to the necessity of applying organic woven material, on self-adhesive paper basis, which prevents the deformation of woven material. This additional admission application of self-adhesive paper backing on organic woven material required additional costs for special equipment, self-adhesive paper basis, the development and application of a new system of filing pigment to the ink cartridges, special cartridges, special textile ink.

The basis of the invention is to create a method of pre-processing of organic woven material for applying a printed image, in which due to the chemical composition of the alkaline solution ensures the procurement of woven material with properties similar to "paper".

The problem is solved in that in the method of pre-processing org what about the material solution, then pressed impregnated woven material and subsequent drying, according to the invention, as a solution applied alkaline solution containing components ammonium sulfate, sodium nitrite, sodium carbonate, thiodiglycol, urea, an adhesive binder, soluziona salt, caustic soda, sodium bicarbonate, glycerin, sodium chloride or Glauber's salt, taken in the following weight ratio, g on 1 l of water:

the ammonium sulfate - 10-50

sodium nitrite - 5-30

sodium carbonate - 0-2

thiodiglycol - 25-100

urea - 10-150

the 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's salt - 20-180,

when the alkaline solution is heated to a temperature sufficient to stretch the surface membranes of cells of woven material, and the impregnated woven material is carried out at elevated pressure, and drying of pressed organic woven material is carried out under the action of mechanical pressure at elevated temperature.

Pre-heating the alkaline solution is necessary to minimize the residence time of the fabric in an alkaline solution davenia of the solution into the fiber in a short period of time to prevent the destructive action of the alkaline solution into fibers. This implementation of the method according to the invention, ensures procurement of organic woven material for use, for example, in an inkjet printer, for printing the image. Under the action of the adhesive binder alkaline solution thread acquires elastic properties due to the bonding of the fibers to each other, and under the action of urea, salt, soluzioni salt, caustic soda subsequent application of pigment, which ensures good adhesion of the pigment to the canvas, the presence in solution of ammonium sulfate, sodium nitrite, thiodiglycol, will increase the brightness, the color intensity of the image, resistance to ultraviolet radiation and other physical and chemical influences, the presence of sodium carbonate, sodium bicarbonate will promote rapid drying of the pigment, the presence in solution of glycerin will help when drawing the image on the workpiece, his photographic authenticity.

After drying the organic fabric under pressure and temperature are blank, for use in a printing device, such as an inkjet printer, which are inherent properties of paper."< other textile companies for printing the image on it with your own dyes, as well as art studios for use as the basis for drawing the image with oil, batik, watercolor, gouache, pastel, printing industry for nanesennya image copying machines. Recommended as a organic woven material to use protein and/or vegetable material, at the same time 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.

Should the alkaline solution to be subjected to preliminary heating 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.

Need in the area of pre-heated alkaline solution with the immersed woven material to support the increased pressure of from about 1.2 to about 10 ATM.

Increased dvojnogo solution into fibers. If the pressure in the solution is below 1, 2 ATM, the woven material will not have time to fully soak solution, and at a pressure greater than 10 atmospheres woven material curls toward the front side, it becomes much stretching that prevents a flat aligned cloth woven from organic material, i.e. the workpiece.

Preferably the extraction of woven material to perform under the action of mechanical pressure in the presence of elevated temperature from about 50 to about 350oC.

Specified temperature range due to the form of a woven material. Protein woven material requires less temperature, and vegetable woven material is greater. At temperatures below the 50oC does not occur alignment material from plant fibers and blended with vegetable fibers. And at temperatures above 350oWith going charring fibers woven material.
