A method of obtaining multicolor pile of drawings /Pat. No. 2172367. IPC7D 04 H 11/00. A method of obtaining a pile of drawings. Berchem E.N., Ivanov O.M., Kozlov M.V. Publ. 20.08.2001, bull. No. 23/ by sequential deposition of cloth of different colors in a nonuniform electric field, divided vertically into two zones with the electric field strength on the surface of the material specified for each application in the range from 1 to 8 kV/see

The disadvantage of this method is that it is impossible to obtain images of a given shape, i.e. it is possible to obtain only geometric or abstract patterns. This is because it is difficult to determine the trajectory of the pile in a nonuniform electric field, because it depends on its potential, the properties of the pile and form the intermediate electrode. The shape of the pattern obtained on the material, does not reproduce the shape of the intermediate electrode.

Also known is a method of obtaining multicolor pile of drawings /Pat. No. 2255154, D 04 H 11/00. The method of obtaining multicolor pile of drawings. Ivanov O.M., Kozlov M.V., konyayeva L.V. Publ. 27.06.2005, bull. No. 18/ by informirovaniya on the boundary of the separation zone, provided job potential boundaries of separation is equal to U1=Uh1/h, where U is the potential of the upper border zone flocking, h1- the height of the lower zone flocking, h - the height of the entire zone flocking.

Getting a pile of drawings as follows. To create, for example, tri-color pattern using two different pile for forming pattern and the third pile is for the background. The bristles of a different color is applied sequentially on the adhesive surface. The first pile is put on the unit having the intermediate electrode with apertures in the form of a figure and a potential equal to U1=Uh1/h, where U is the potential of the upper border zone flocking, h1- the height of the lower zone flocking, h - the height of the entire zone flocking. Under these conditions, the intermediate electrode does not change the potential distribution in the area of the flocking and the pile passes through the holes, not deviating from the trajectory, i.e. as if no intermediate electrode. Thus, the material obtained image corresponding to the shape of the holes on the intermediate electrode. Then the material is coated with a first pile is placed on another installation for flocking, which was pre-loaded second pile and which has an intermediate electrode with a potential equal to U1=Uh1/h, with a different shape. Chi is lo repetitions of this operation depends on the number of selectable colors. The final step material coated with a picture placed on flokiruyutsya installation without intermediate electrode, i.e. in a homogeneous electric field. During the last flocking fibers fill the space left free.

In this way clearly set tension both zones and potential boundary zones that uniquely identifies the type of the received NAP figure, and therefore limits the possibility of regulating the form and clarity of color transitions, i.e. getting clear boundaries or smooth color transition, as well as the forms of the figure.

The technical result of the proposed solutions is to expand the possibility of regulating forms of illustration and clarity of color transitions due to the formation of NAP pattern by varying the electric field strength at the same time in the initial zone in the range of En=(U-U1)/(h-h1) to En≈0, and in the end zone after passing the pile boundary in the range of Eto=(U1-U0)/h1to Eto=(U-U0)/h1by setting the potential of the boundaries separating areas from U1=(U-U0)h1/h to U1=U.

This object is achieved in that in a method of producing a multicolored pile of drawings, consisting of sequential application of cloth of different colors is the electric field, divided according to the direction of movement of the pile into two zones start and end with the last application in a uniform field, with one zone, the electric field strength in all applications of the pile, except the last change simultaneously in the initial zone in the range of En=(U-U1)/(h-h1) to En≈0, and in the end zone after passing the pile boundary from Sto=(U1-U0)/h1to Eto=(U-U0)/h1by setting the potential of the boundary zones from U1=(U-U0)h1/h to U1=U, where U is the potential of the external borders of the initial zone flocking, U0- the potential of the external borders of the end zone flocking, h1- the size of the target zone flocking in the direction of the pile, h is the total size of both areas of flocking in the direction of the pile.

The known method (A.S. 814475, USSR, 05 D 1/04, Appl. 02.04.76, publ. 23.03.81, bull. No. 11) application of the NAP, including orientation and deposition of fibers in an electric field to the core by the formation in the zone of orientation and deposition of two regions, one of which is characterized by the electric field strength of 0.5 to 4 kV/cm and a length exceeding the length of the pile in 3-20 times, the other tension 5-7 kV/see This method is intended to increase the density of the pile on blokirovannom material and is not intended to be the Yong to create a pile of drawings.

Only declare a set of actions with the regime's performance ensures the achievement of the technical result of the above. Thus, the inventive method has significant differences.

Getting a pile of drawings carried out by consecutive application of Warsow different colors on the surface of the material, pre-coated with adhesive. The first pile is put in the electric field at the facility, with the intermediate electrode or with holes of various shapes, or representing, for example, a frame with the wires bent in different ways. The potential of the intermediate electrode set according to the set requirements to the form of the figure in the range from U1=(U-U0)h1/h to U1=U. thus, the electric field in the initial zone in the direction of movement of the pile will be respectively set in the range in the range of En=(U-U1)/(h-h1) to En≈0, and in the end zone from Fto=(U1-U0)/h1to Eto=(U-U0)/h1. After application of the pile of the first color on the adhesive surface is formed felted picture with smooth or contrasting color borders, to a greater or lesser extent, the shape of the holes on the intermediate electrode. All this is determined by the value of the intermediate potential is about electrode.

Then the material is coated with a pile pattern of the first color is placed in another flokiruyutsya installation, which was pre-loaded pile second color and which has an intermediate electrode having a different shape, and which is filed with a different value of the potential, corresponding to the requirements Varsovia the picture of this color, but in the same range of possible changes of the potential, as in the first case.

The number of repetitions of this operation depends on the number of selected colors. The last step is to carry out the application of pile installation without intermediate electrode. During this last flocking fibers fill the adhesive surface remaining free after the previous application Warsaw. Thus, different versions of the drawings in this way you can receive not only due to the different shape of the intermediate electrode, and setting different values of tension start and end zones by setting the potential of the intermediate electrode in the specified range.

Example 1 here is an option of a NAP pattern of three colors. The application of the pile was carried out in a laboratory setup, which is a chamber with two electrodes (drawing) - the top 1 and bottom 3. The upper electrode is a bunker for a NAP and has a mesh bottom, through which in the C goes into the application zone. Feed pile is made by vibration of the hopper 1 with lint from the motor with a Cam. The hopper is connected to the high voltage source with adjustable, and the bottom electrode kasemset, i.e. connected to the ground potential U0=0. Between the upper and lower electrodes at a given distance was set intermediate electrode 2, dividing the interelectrode space into two zones - the start and end. To the intermediate electrode 2 was applied potential from the second high voltage source, which can vary its potential within the specified limits.

The surface of the cotton fabric was covered with a uniform layer of glue TUBVINIL 235 MS German company SNT. Flocking was implemented from the top down using installation scheme which is the same as on the drawing. The upper electrode 1 or the outer boundary of the primary zone flocking (A) is a mesh bottom of the hopper and has the potential U=60 kV, and the lower electrode 3 or the outer boundary of the end zone flocking (C) grounded, i.e. it has zero potential U0=0. The boundary of the separation zone 2 is a thin metal plate with holes for the passage of the pile. Getting a NAP drawing was performed using three Warsow different color: I - blue of the pile polyamide fiber length of 0.6 is m and the linear density of 0.33 Tex; II - pile yellow color of the polyamide fiber length of 1.0 mm and a linear density of 0.33 Tex; III - pile white viscose fiber length of 1.0 mm and a linear density of 0.33 Tex. The first application is performed pile I using the intermediate electrode has 4 round holes with a diameter of 3 see the potential of the upper electrode was equal to U=60 kV. The intermediate electrode, in this case, was located in the middle between the upper and lower electrodes, the distance to which was 6 see the Potential of the intermediate electrode was set equal to U1=(U-U0)h1/h=30 kV, while the tension in the initial zone was equal to En=(U-U1)/(h-h1)=5 kV/cm, and the tension in the end zone Eto=(U1-U0)/h1=5 kV/see

The material is then placed in the next installation for flocking, which had previously been loaded pile II. The intermediate electrode in this case was located, as in the first case, and had 4 rectangular holes arranged so that the previously obtained tufted circles were located in the center of these rectangles. The potential of the upper and intermediate electrodes was set equal to U=U1=30 kV, and the lower U0=0. The electric field strength in this case was in the initial zone En≈0, end zone Eto=U1/h1ࣈ 5 kV/see

The last pile (III) was applied without intermediate electrode when the distance between the upper and lower electrodes h=12 cm, the potential of the upper electrode U=60 kV, and the potential of the lower electrode U0=0.

As a result of this process was obtained tufted tri-color pattern that resembles the following: blue tufted circles with clear, sharp boundaries inside yellow NAP rectangle (transition from 1 pile to the 2nd), which, in turn, is very smooth color transitions along the border to the white color of the pile III (transition from the 2nd pile to the 3rd).

All examples of making pile of drawings (the first and the second application), including the described example 1, are summarized in table. For the third application, all of the examples used pile III in the same mode: voltage 60 kV, without intermediate electrode when the distance between the electrodes 12 cm, i.e. the tension was 5 kV/see the Results were evaluated according to the "width" of the zone color transitions (clear or smooth color transition): from the 1st NAP at 2 th (S1and from the 2nd to the 3rd (S2), and according to the forms of NAP figure - shaped openings on the intermediate electrode.

To quantify the width of the zone color transitions on flokirovaniya the drawings was used to scan the drawings and their subsequent processing in Photoshop that allows you to define what elite distance, where there is a change in color from one pile to another.

In all the examples presented in the table, the interelectrode distance h in all cases was 12 see Consistency pile of drawings in all experiments, the same circle, rectangle, background.

The first three examples (1-3) show the possibility of gradual changes in the definition of the picture: contrast color transition for a smooth between 1-mi 2-m pile, by changing the initial tension in the area during application of the 1st pile (5 kV/cm, 2.5 kV/cm, 0 kV/cm), with a smooth color transition from the 2nd pile to 3rd in all cases.

The following three examples (4-6) are distinguished by the fact that the boundary between the 2nd and 3rd lint sufficiently clear (1-1 .5 mm), while maintaining the same pattern of color transition from the 1st to the 2nd pile.

In examples 7 to 10 was the first to inflict more long pile (1 mm). The difference between similar examples, but when applying the first short pile (0.6 mm), is that you get a smoother color transition from the 1st to the 2nd pile: 1.5 mm (1) and 2.0 mm (7); 1.1 mm (4) and 2.2 mm (8); 16,1 mm (6) and 20.2 mm (9); 15.1 mm (3) and 19.0 mm (10).

Examples 11 through 14 show the possibility of obtaining pile ri is uncov in other respects h 1/h=0,33 for the 1st and 2nd application. In this case, only increasing contrast compared with similar examples, where h1/h=0,5: 0.9mm (11) and 1.5 mm (1), 0.9 mm (12) and 1.1 mm (4), 13,0 mm (13) and 15.1 mm (3), 13.2 mm (14) and 16.1 mm (6).

Examples 15 to 18 are different from the previous (11-14) what first struck long pile (1 mm). There have been more smooth color transitions compared with similar examples.

Examples 19, 20 show the possibility of obtaining a pile of drawings with a lower potential on the top electrode (U). Because of less tension (4 kV/cm) got a smoother color transition from the 1st pile to the 2nd compared to the same examples 4 and 1, respectively. In these examples, the application of the 2nd NAP was carried out at a lower intermediate location of the electrode (h1/h=0,33). The area of the gradient S2in this case, increases in comparison with examples 12 and 13, respectively.

Examples 21 to 24 show the possibility of obtaining a pile of drawings, in another relation of h1/h=0.67 and for the 1st and 2nd application. In this case, increasing the width of the transition zone color compared with similar examples, where h1/h=0,5 (21 - 1, 22 - 4, 23 - 3, 24 - 6).

In example 25 was used glue polyvinyl acetate, and the pile was applied as in example 2, the size and contrast of the obtained images corresponding to example 1, g is e used glue TUBVINIL 235 MS under the same conditions applying to the pile.

Examples 26, 27 are distinguished by the fact that as the basis was chosen cardboard, while in example 26 was used glue polyvinyl acetate, as in example 27 TUBVINIL 235 MS. The size and contrast of the obtained images in the two cases are identical and correspond to the figures obtained in example 1.

The data in the table indicate the possibility of regulating the appearance pile of drawings in a wide range by changing the tension of the start and end zones, by setting the potential of the boundary zones in the specified range.

The method of obtaining multicolor pile of drawings, consisting of sequential application of cloth of different colors in an electric field, divided in the direction of movement of the pile into two zones, starting and ending with the last application in a uniform field, with one zone, characterized in that the electric field strength in all applications of the pile, except the last change simultaneously in the initial zone in the range of En=(U-U1)/(h-h1) to En≈0, and in the end zone after passing the pile boundary in the range of Eto=(U1-U0)/h1to Eto=(U-U0)/h1by specifying the potential boundaries of separation zones from U1=(U-U0)h1/h to U1=U, where U is the potential of the external borders of the initial zone fakirov the Oia, U0- the potential of the external borders of the end zone flocking, h1- the size of the target zone flocking in the direction of the pile, h - the total amount of the initial and final areas of flocking in the direction of the pile.
