Description

Technical field

The invention relates to techniques for the artistic painting of fabrics using the hot batik method, which involves preliminary (before dyeing) application of a reservation coating in the form of molten wax on separate sections of the fabric.

State of the art

Known hand tools for applying molten wax used in dentistry [1] and in the technique of hot batik [2]. However, it is difficult to apply wax lines of varying thickness with these tools, which is often required for artistic painting of fabrics.

The closest analogue of the proposed tool is a hand tool for applying molten wax to a fabric, comprising a body, an electric heating tank built in it and equipped with loading and outlet openings and a head with a through channel installed in the outlet of the electric heating tank [3]. When using this tool, pieces of solid wax are placed through a loading hole in an electric heating container, melted in it, and pressing the hole of the head to the stretched fabric, the tool is moved to cover with molten wax flowing through the through hole of the head sections of fabric in accordance with the artistic design of the painting. The thickness of the applied lines can be varied within small limits, changing the tilt of the tool with respect to the fabric.

The tool [3] is used for artistic painting of fabrics, but it has the following disadvantages:

- uncontrolled leakage of molten wax from the through channel of the head, because of which it is necessary to cover the channel of the head with a finger in the absence of its contact with the tissue;

- overhang on the head of drops of wax when it is torn from the fabric;

- the possibility of leakage of molten wax through the loading hole when moving the tool;

- inadmissibility of canting of a tool with molten wax;

- limited ability to change the thickness of the applied wax lines and, therefore, the need to change the head of the tool during the painting process, the artistic concept of which requires the application of wax lines, the thickness of which varies over a wide range.

In general, the disadvantage of the known tool [3] can be formulated as an inconvenience in use and limited technical capabilities for the implementation of the artistic intent of painting fabrics.

Disclosure of the invention

The objective of the invention is to increase the convenience and expand the capabilities of the tool when it is used in painting fabrics.

The technical result of the invention consists in creating a more convenient tool to use, which, in the technique of hot batik, applies thinner lines of wax to the fabric and changes the thickness of the applied lines by varying the force of pressing the tool on the fabric.

The subject of the invention is a hand tool for applying molten wax to a fabric, comprising a housing, an electric heating container integrated therein, equipped with a throttling and outlet openings, a head with a through channel installed in the outlet, in which a needle with a rounded tip is placed, made with the possibility of smooth overlapping of the passage the cross-section of the channel with the longitudinal movement of the needle with the external location of its tip, while the needle is spring-loaded by an elastic element in the direction of narrowing of the -religious channels, the elastic member is fixed in a holder mounted on the head, and the radius of curvature of the tip of the needle is greater than 0.15 mm.

The invention has refinements and developments related to particular cases of its implementation.

The implementation of the invention

The drawing shows a General view of the tool according to the invention, taking into account its refinements and developments.

The tool comprises a housing 1 and an electric heating container 2 built into it. The electric heater of the container 2 can be made, for example, nichrome with mica thermal insulation.

A head 4 is installed in the outlet 3 of the container 2 with a through tapering channel 5. A needle 6 is placed in the channel 5. The elastic element 7 springs the needle 6 in the direction of the outwardly narrowing channel 8 5. The element 7 is fixed in a sleeve 9, which is mounted on the thread with an open end on the head 4.

Side walls 10 are provided in the walls of the sleeve 9, through which molten wax flows into the channel 5. The container 2 and the channel 5 are separated by a filter 11 (made, for example, from a piece of fabric) covering the holes 10.

The tank 2 is equipped with a narrow throttling hole 12, which can be performed, for example, in the plug 13 mounted on a thread in the loading hole 14 of the tank 2.

The tip 15 of the needle 6, a spring-loaded element 7 (for example, a coil spring), comes out from the narrowing 8 of the channel 5 of the head 4. In this case, small movements of the needle 6 along the axis of the channel 5, in which the tip 15 of the needle 6 remains outside (i.e., completely does not enter the channel 5), they allow smoothly blocking the channel 5 (i.e., smoothly change its bore, determined by the gap between the needle 6 and channel 5 in the zone of its narrowing 8). So that the needle 6 does not pierce the fabric when applying wax to it, the tip 15 is rounded. The radius of curvature of the tip 15 is not less than 0.15 mm.

The head 4 is installed in the hole 3 on the thread and is equipped with a flange 16, pressing the gasket 17, the sealing hole 3.

The device operates as follows.

The cap 13 is turned off and the container 2 through the hole 14 is filled with solid pieces of wax. (If there is no hole 14, the loading of solid wax can be carried out through the outlet 3 after removing the head 4.) The plug 13 is screwed (or the head 4 is installed in the hole 3) and the container 2 is connected using an electric cord, usually through a regulator, to a safe power source.

The wax is melted and through the filter 11, which does not allow foreign inclusions, flows through the holes 10 into the channel 5.

After that, the tool is ready for applying molten wax on the painted fabric.

Since the elastic element 7 springs the needle 6 with the point outward, before the needle 15 presses the needle 6 onto the fabric being painted, the channel 5 is completely covered by the spring-loaded needle 6 (there is no gap) and the molten wax does not flow out of the head 4. This, as well as the presence of a plug 13 in the loading hole 14, allows you to move and tilt the tool, without fear of leakage or overhang of drops of molten wax.

The tool is brought to the surface of the stretched painted fabric and, touching it with the tip of 15 needles 6, lines of wax are applied. With increasing pressure on the fabric, the needle 6, overcoming the resistance of the elastic element 7, moves along the channel 5 towards its wide end facing the container 2. At the same time, the gap between the needle and the channel 5 in the zone of its narrowing 8 increases, the passage section through which increases molten wax flows out of the tool head 4, and as a result, the thickness of the wax line applied to the fabric increases. When reducing the pressure of the needle 6 on the painted fabric, the elastic element 7 returns the needle 6 back to the narrowing zone 8 of the channel 5 and the thickness of the applied line decreases.

A necessary condition for the outflow of wax from the container 2 through the channel 5 of the head 4 and, therefore, the operation of the device is the presence of a throttling hole 12, which provides access to external air in the container 2 and, thereby, preventing a decrease in pressure in it when the molten wax partially flows out.
