Description

Technical Field

[0001] The invention belongs to art processing technology, and in particular relates to a natural rubber release agent for silk hand-painting and a hand-painting method. Background Art

[0002] Silk painting is a painting or calligraphy drawn or woven with silk as the medium. However, traditional silk painting is complicated and requires strong painting skills. Especially for those who want to decorate their homes by themselves, silk painting is daunting. At present, silk hand-painted products are basically divided into color-leveling, salt-sprinkling, paint hand-painting and dye hand-painting with release agents. Among them, silk hand-painted products with release agents have lively and natural patterns. Designers can draw patterns on the silk surface at will, because they use dye solution, which is almost 100% penetrating, avoiding the use of printing paste on printed fabrics, which causes dye penetration to be hindered.

[0003] In the prior art, after the product is steamed and washed, a washing process is specially added to remove the release agent on the fabric, which affects the gloss of the silk. The prior art discloses a release glue, which is made by mixing the following components by weight: 50-60 parts of polybutyl acrylate, 5-10 parts of CMC, 15-20 parts of gelatin, and 25-35 parts of paraffin oil; although it can play an isolating role, the chemical raw materials used are environmentally unfriendly, and a special rinsing liquid is required to reduce the effect of the release agent on the soft feel of the silk itself. Summary of the invention

[0004] The present invention discloses a natural rubber release agent for silk hand-painting and a hand-painting method. Gasoline is used as a solvent to dissolve small granular natural rubber as a release agent. The release agent has good environmental protection, plasticity, and anti-staining properties, and is easy to clean without leaving traces. No additional rinsing steps are required. The release agent can be used as the dye is finished. The lines drawn by the release agent are smooth and uniform in thickness, and the hand feels soft and not hard, overcoming the defects of traditional release agents such as block solidification, stiff hand feel, and difficulty in cleaning. In particular, the new release agent disclosed for the first time in the present invention has no effect on the soft hand feel of the silk itself after being used in the production of silk hand-painting.

[0005] The present invention adopts the following technical scheme.

[0006] A natural rubber release agent for silk hand-painting comprises a natural rubber solution.

[0007] In the present invention, in the natural rubber solution, the solvent is gasoline, preferably 92# or 98# gasoline.

[0008] In the present invention, the mass percentage of natural rubber in the natural rubber solution is 1%-5%; preferably, the mass percentage of natural rubber in the natural rubber solution is 2%-4%.

[0009] The invention discloses application of natural rubber as a silk hand-painted release agent.

[0010] The invention discloses application of natural rubber in preparing a silk hand-painted release agent.

[0011] The invention discloses a silk hand-painting method, comprising the following steps: (1) Drawing the desired wireframe pattern on the silk fabric with a release agent; or drawing the desired wireframe pattern on the silk fabric with a release agent containing oily toner dye; the release agent is a natural rubber solution; (2) The wireframe pattern is filled with water-soluble acid dye solution, then dried, fixed, and the floating color is removed to complete the silk hand-painting.

[0012] In the present invention, in step (1), the wireframe pattern is designed according to a hand-drawn drawing, which is a conventional technique; the specific drawing is also a conventional technique in the art.

[0013] In the present invention, in step (1), in the release agent containing the oily toner dye, the mass of the oily toner is 0.5%-1% of the mass of the release agent.

[0014] In the present invention, in step (2), the water-soluble acid dye solution is prepared according to the hand-drawn drawing, which is a conventional technique; the specific filling is also a conventional technique in the art.

[0015] In the present invention, in step (2), drying, fixing, and removing floating colors are conventional steps of dyeing, and are conventionally performed according to the characteristics of the dye used for painting, and do not affect the realization of the technical effect of the present invention.

[0016] In the present invention, no additional treatment is required for the isolation glue, such as no additional washing.

[0017] The existing technologies all use petroleum products as the components of silk hand-painted isolation glue, such as petroleum resin, acrylic resin, etc., which is not only not conducive to environmental protection, but also inevitably weakens the feel of the silk itself. The present invention creatively uses natural rubber solution as an isolation agent for silk hand-painting for the first time. The preparation is very simple. The isolation agent is obtained by adding natural rubber particles to gasoline; in particular, the isolation agent of the present invention does not require additional washing, and the hand-painting can be completed after the conventional dyeing steps are completed. The experiment fully proves that the isolation agent of the present invention has no weakening effect on the feel of the silk itself. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is the first to use natural rubber solution as a release agent for silk hand-painting. The preparation is very simple. The release agent is obtained by adding natural rubber particles to gasoline. In particular, the release agent of the present invention does not require additional washing, and hand-painting can be completed after the conventional dyeing steps are completed.

[0040] Figure 6 For the photo of the hand-painted silk above.

[0041] Comparison example Referring to Example 7, a wireframe pattern was drawn using a mainstream release agent product currently available on the market. On the resulting hand-painted silk, the release agent was obvious and difficult to clean, and the hand feel of the silk was reduced.

[0042] Comparative Example Referring to the prior art, an isolation adhesive is prepared by heating and mixing polybutyl acrylate, carboxymethyl cellulose, gelatin and paraffin oil. Its preparation and application performance are obviously inferior to the isolation agent of the present invention. After hand-painting with it as an isolation adhesive (refer to Example 7), washing with clean water to remove the floating color will cause the feel of the hand-painted silk to deteriorate.

[0043] Sensory touch: 30 subjects, including 12 boys and 18 girls, made sensory judgments by touching the silk parts treated with release agents, compared with the original silk parts without release agents.

[0044]

[0045] The present invention discloses a method for preparing and using a natural rubber release agent for silk hand-painting, comprising the following steps: (1) shearing natural rubber into small particles; (2) using 92# or 98# gasoline as a solvent to dissolve the small particles of natural rubber, with a mass ratio of 2%-4% natural rubber to 96%-98% gasoline; (3) The dissolution time is 24h-48h and the release agent is fully shaken to make it evenly. (4) Draw the required wireframe pattern on the silk fabric with the release agent: the wireframe pattern is blank white with the release agent concentrate, and the colored wireframe pattern needs to add oily color powder dye to the release agent and shake it evenly to dissolve; (5) Fill the wireframe pattern with water-soluble acid dye solution, and place it at room temperature to dry for 1-2h after coloring; (6) Remove the silk fabric from the stretch frame and place it in a steamer for 40-45min to fix the color at a temperature of 105℃-110℃; (7) Rinse the silk fabric in clean water for 2-3min after hanging and steaming to remove the floating color, dehydrate and dry in the shade, and then iron it flat. This release agent has good environmental protection, plasticity, and anti-dyeing properties, and is easy to clean without leaving traces. The lines drawn by the release agent are smooth and uniform in thickness, and the hand feels soft and not hard, overcoming the defects of traditional release agents such as block solidification, stiff hand feel, and difficulty in cleaning.
