Description

Technical Field

[0001] The invention belongs to the technical field of craft painting production, and particularly relates to a method for producing straw heat transfer. Background Art

[0002] Wheat, as the most precious of the five grains, is one of the sources of life that people cannot live without. The raw material of wheat straw painting is the most common wheat straw in the farmland. It originated from the folks and uses wheat straw, a natural resource of the folks. After more than 30 processing steps, it can be cut and pasted according to the needs of the work without coloring. It organically combines traditional crafts with modern science and technology. On the basis of maintaining the natural luster and texture of wheat straw, it boldly absorbs many artistic expression techniques such as Chinese painting, printmaking, and paper-cutting, and ingeniously makes it into a handicraft boutique with ancient elegance, magnificence, vividness, and lifelikeness, which is known as a unique Chinese folk art.

[0003] In recent years, as people's quality requirements for straw paintings have increased, traditional straw painting production technology has been difficult to meet market requirements. The three-dimensional sense and viewing degree of straw paintings need to be improved. Therefore, it is necessary to develop a new straw painting process to give it a higher three-dimensional sense and viewing degree. Summary of the invention

[0004] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a method for making straw heat transfer with high three-dimensional effect and ornamental value.

[0005] The purpose of the present invention is achieved through the following technical solutions: a method for making straw heat transfer, which comprises the following steps: S1. Material selection and processing: select wheat straw within 15 days after the Grain Full Festival in the lunar calendar, soak, fumigate and boil and dye the wheat straw, and break and polish the boiled and dyed wheat straw; S2. Gluing: Paste the polished straw into pictures, decompose and paste the designed patterns into pieces, and let them dry naturally; S3 high temperature ironing tracing chicks: use an iron to paste the straw on the drawing high temperature ironing tracing chicks, the ironing temperature is 65 ~ 70 ℃, ironing until flat and dry, use a soldering pen or soldering iron to hot draw a pattern on the pasted patch, the temperature of the soldering pen or soldering iron is controlled at 500 ~ 900 ℃; S4. Ironing: The parts of the hot stamping are spliced ​​and pasted together to form a whole picture, and then the whole picture is ironed until dry and flat, and the temperature of the iron is 65 to 70 ° C; S5. Post-processing: putting the ironed painting on the board and frame.

[0006] As a preferred technical solution, the immersion in step S1 is performed using a sodium hydroxide solution with a mass percentage concentration of 0.01 to 0.07%, and the immersion time is 3 to 5 minutes.

[0007] As a preferred technical solution, the fumigation in step S1 adopts sulfur fumigation bleaching, the amount of sulfur used is ≤12g per kilogram of wheat straw, and the fumigation time is 5 to 6 hours.

[0008] As a preferred technical solution, the boiling and dyeing in step S1 uses plant dyes, and the boiling and dyeing time is 30 to 120 minutes.

[0009] Furthermore, the plant dyes are hematoxylin, gardenia and indigo.

[0010] As a preferred technical solution, the electric soldering pen in step S3 uses sliding, coating, rubbing and dotting techniques to heat-draw different shades of color and lines on the pasted patch.

[0011] As a preferred technical solution, after the fumigation treatment in step S1, the wheat straw is naturally air-dried, and the humidity of the air-dried straw is less than 50%.

[0012] In the present invention: 1. Material selection and processing: Material selection: Select wheat straw within 15 days after the Grain Full Festival in the lunar calendar. At this time, the wheat is mature, the straw has the best toughness, the straw fiber is neither soft nor dry, and it is easy to break and process.

[0013] (1) Winter wheat grown on grey loam soil is the best choice, with strong stalks, long nodes and moderate thickness.

[0014] (2) Materials must be selected on site and their length and length must be consistent.

[0015] Soaking: Soak the straw in sodium hydroxide solution in a safe area with good ventilation. In order to corrode and soften the straw, the ratio of sodium hydroxide to water is usually 1:30. Soak the straw for 3-5 minutes, rinse it with clean water after soaking to remove the residual solution.

[0016] Fumigation: Sulfur fumigation bleaching must be carried out in a well-ventilated environment. During the steaming process, spray a small amount of distilled water to increase the toughness of the straw and facilitate the thinning of the strips.

[0017] Boiling and dyeing: Boiling and dyeing with plants and minerals based on natural pigments. Generally, plant dyes are used, such as hematoxylin, which is dark red in color and can be boiled to produce red. Gardenia can be dyed yellow, and indigo can be processed to produce blue. These plant dyes are natural and environmentally friendly, and can give the straw a natural and simple color. Boiling and dyeing takes about 30 minutes to 2 hours. During the boiling and dyeing process, proper stirring should be done. The three primary colors of red, yellow, and green or other colors should be used. The coloring temperature should be controlled in time. First, boil the dye over high heat for 5-10 minutes, then simmer over low heat to allow the straw to fully absorb the dye. Boil over low heat for 1-30 hours. During the boiling and dyeing process, attention should be paid to stirring to prevent the straw from being dyed too dark. After boiling and dyeing, it should be dried in the sun and kept properly dry and wet.

[0018] Breaking and grinding: Breaking and grinding wheat straw, using scissors to split the wheat straw into two parts from bottom to top. Grinding is to remove the inner part of the wheat straw, grind it flat, take its leather, and make the wheat straw bright in color. Technical requirements are that the breaking degree is uniform, the degree is straight, and the blade is free of stubble. Grinding requires scraping the grains inside and removing the knots outside, being as flexible as paper and as shiny as satin. Use 200-grit sandpaper to grind the wheat straw, scrape the inner part, remove the knots outside, grind it flat and shiny. Use a blade to scrape and grind the wheat straw, two, three, seven, nine, etc., as thin as a hair.

[0019] 2. Stick together According to the requirements of the pattern modeling, design the drawings, use the polished straw to express the concave and convex turns of the object, the yin and yang, and the arrangement of the straw should be consistent with the direction of the pattern. Use the straw to paste the picture, decompose and paste the designed pattern into pieces, decompose and paste different colors, paste smoothly and seamlessly, pay attention to the different pasting methods of "horizontal, vertical, oblique, and spiral", so that the straw texture is consistent with the pattern requirements. After pasting, check for leaks, fill them in place, and let them dry naturally.

[0020] 3. High temperature ironing and drawing: Use an iron to flatten and dry it, and control the temperature at 65℃ ~ 70℃. Check for leaks due to thermal expansion and contraction. If there are any leaks, cut the straw into strips and fill them in place.

[0021] Use an electric soldering pen or electric iron to heat-paint different shades of color and lines on the pasted patch through different techniques such as "slipping, coating, rubbing, and dotting" to complete the whole painting pattern. The temperature of the electric soldering pen must be controlled at 500℃~900℃; (1) The technical requirements must be faithful to the design drawings. The transition between levels must be natural and soft, and the color must be even.

[0022] (2) When branding, the color should be bright and shiny.

[0023] (3) The temperature of the colored straw must be strictly controlled. The temperature of the electric soldering pen must be controlled at 500℃~900℃. The glue used in the heat transfer will undergo physical changes at high temperatures. The glue will melt at high temperatures and can better adhere to fabrics and other attached materials. The glue will re-solidify, thereby firmly fixing the pattern. After the pattern cools down, the shape and color of the pattern will be fixed. The straw also has a certain tolerance and will not be damaged during the high-temperature shaping process. The entire heat transfer can be shaped through high-temperature treatment, so that the dyeing is bright and bright with alternating layers.

[0024] 4.Combination ironing: The various parts of the picture are spliced ​​together and pasted together to form an overall picture of patterns or texts. The details are depicted with an electric soldering pen or electric iron, and then the whole is ironed to make it seamless and the jade mirror stand out.

[0025] (1) Technical requirements: The finishing touch should be added to the re-creation, and full use should be made of the hot stamping technique to make the whole work harmonious, elegant, vivid and lifelike.

[0026] (2) It is required to iron flat and perform heat treatment at low temperature, emphasizing flatness, brightness and maintaining natural luster.

[0027] (3) Inspect product quality, trim the edges, make sure the surface is smooth and free of thorns, and repair any missing parts.

[0028] 5. On the board: Put the work on a panel, paste the necessary board painting decorations, and add its title and seal. The technical requirements are smoothness, elegant decoration, and just the right seal and title.

[0029] 6. Frame Binding Different frames are configured according to different shapes for binding. The frame paint surface is required to be "even, clean and bright", and the frame shape is required to be elegant and without gaps; the appearance must be free of pollution, glue marks, and scratches, and must be beautiful and tidy, meeting the overall requirements of flatness, neatness, fineness, brightness, uniformity and smoothness.

[0030] The invention has the following advantages: the invention discloses a method for making straw hot stamping, which uses a variety of tools such as electric soldering pens, irons, and electric soldering irons to perform ironing in the process of making flat straw paintings. During the high-temperature treatment process, the temperature of the electric soldering pens or electric soldering irons must be controlled at 500°C to 900°C, and the prototype of the picture is formed by using different techniques such as "slipping, coating, rubbing, and dotting". After the overall picture is spliced ​​and glued according to the design drawing, the gaps due to thermal expansion and contraction are filled in time, the details are depicted with an electric soldering iron, and the painting is ironed and dried, and the painting is flattened to form a whole. The painting has strong artistic appeal and a strong three-dimensional sense. Without the need for coloring, the ordinary straw painting is given the characteristics of three-dimensional sense, heaviness, color gradient, etc. Its technical effect makes the work a well-loved work of art, and provides a production method with more ornamental and collection value for traditional straw painting.
