[0044] S1. Deeply clean the cotton blanket with a neutral detergent, wring it out after washing, and set it aside; wherein, the neutral detergent is a neutral laundry detergent with a pH of 6.4, and the neutral laundry detergent is an existing detergent, which will not be elaborated here.

[0045] S2. Refine the printed silk target fabric, that is, deeply clean it with a neutral detergent, and set it aside; wherein, the neutral detergent is a neutral laundry detergent with a pH of 6.4.

[0046] S3. Immerse the printed silk target fabric in a mordant. Immerse the printed silk target fabric cleaned in S2 in a mordant solution composed of a mixture of potassium alum dodecahydrate, ferrous sulfate, calcium carbonate, and acetic acid, which respectively account for 10% of the mass of the silk target fabric, 1%, 5%, and 5% of the silk target fabric, for mordanting. After mordanting is completed, wring the printed silk target fabric until it stops dripping, and set it aside;

[0047] S4. Specifically, the process of immersing the printed silk target fabric in the mordant is as follows: Add potassium alum dodecahydrate mordant at 10% of the weight of the printed silk target fabric to 4 liters of clear water at a temperature of 50°C to 60°C, and continuously stir during the addition process. The mass of the clear water is 4 times the mass of the printed silk target fabric. The entire stirring process is completed in an existing container. The clear water can completely immerse the printed silk target fabric and make the printed silk target fabric in a suspended state. Then add ferrous sulfate mordant at 1% of the weight of the printed silk target fabric, and continuously stir during the addition process. Then add calcium carbonate mordant at 5% of the weight of the printed silk target fabric, and continuously stir during the addition process. Then add acetic acid mordant at 5% of the weight of the printed silk target fabric, and continuously stir during the addition process; after fully dissolving, put the printed silk target fabric after being cleaned in S2, gently knead and press it to make the printed silk target fabric fully contact with the composite mordant, mordant evenly, and let it stand for 8 hours or more. After mordanting is completed, wring the printed silk target fabric until it stops dripping, and set it aside.

[0048] S5. Lay the printed silk target fabric mordanted in S4 flat, and place clean plant leaves on the surface of the laid printed silk target fabric; cover the printed silk target fabric with plant leaves with the cotton blanket treated in S1, and gently press and flatten it to ensure that the cotton blanket is in close contact with the plant and the printed silk target fabric;

Soak the cotton blanket treated by S1 in it, gently rub and press to make the cotton cover cloth fully contact with the plant dye water, mordanting evenly, soak for 8 hours, wring out for use. Plant dye water is a mixture of extracts from natural plants and clean water. For example, natural plants such as sycamore leaves (black-gray), loquat leaves (light pink), pomegranate peels (yellow-green) are added to 4 liters of clean water according to 1 to 1.5 kg and boiled for 30 minutes, and then left to stand for 5 hours or more to obtain an extract. The remaining residue can be boiled with water 1 to 2 times, and added to the extract obtained above, filtered out the dye residue and used. If you want a rich color, you can boil the extract again to make it more concentrated.

[0057] S3, refining the printed and dyed silk target fabric, that is, deep cleaning it with a neutral detergent for standby use; wherein the neutral detergent is a neutral laundry detergent with a pH value of 6.4.

[0058] S4. Immerse the dyed and printed real silk target fabric after cleaning in step S3 in a mordant solution composed of a mixture of 10% potassium alum dodecahydrate + 1% ferrous sulfate + 5% acetic acid for mordanting. After the mordanting is completed, wring the dyed and printed real silk target fabric until it stops dripping, and set it aside for later use.

[0059] S5. Specifically, the process of immersing the dyed and printed real silk target fabric in the mordant is as follows: Add 10% of the weight of the dyed and printed real silk target fabric of potassium alum dodecahydrate mordant to 4 liters of clear water at a temperature of 50°C to 60°C. During the addition process, continuously stir. The mass of the clear water is 4 times the mass of the dyed and printed real silk target fabric. The entire stirring process is completed in an existing container. The clear water can completely immerse the dyed and printed real silk target fabric and keep the dyed and printed real silk target fabric in a suspended state. Then add 1% of the weight of the dyed and printed real silk target fabric of ferrous sulfate mordant, and continuously stir during the addition process. Then add 5% of the weight of the dyed and printed real silk target fabric of calcium carbonate dye, and continuously stir during the addition process. Then add 5% of the weight of the dyed and printed real silk target fabric of acetic acid mordant, and continuously stir during the addition process. After fully dissolving, put the dyed and printed real silk target fabric after cleaning in step S2, gently knead and press it to make the dyed and printed real silk target fabric fully contact with the composite mordant, and mordant evenly. Let it stand for 8 hours or more. After the mordanting is completed, wring the dyed and printed real silk target fabric until it stops dripping, and set it aside for later use.

[0060] S6. Lay the dyed and printed real silk target fabric after mordanting in step S5 flat, and place clean plant leaves on the surface of the laid flat dyed and printed real silk target fabric; Cover the dyed and printed real silk target fabric with plant leaves with the cotton blanket after being treated in step S2, and gently press and smooth it to ensure that the cotton blanket is closely attached to the plant and the dyed and printed real silk target fabric.

[0061] S7. Lay a plastic barrier on the cotton blanket, and use a stick made of high-temperature resistant material to slowly roll up the plastic barrier, the cotton blanket, the plant leaves and the dyed and printed real silk target fabric from bottom to top until the dyed and printed real silk target fabric is on the outermost layer, and then tie up the rolled dyed and printed real silk target fabric; The stick is a solid wood stick.

[0062] S8. Steam the tied dyed and printed real silk target fabric in step S7 for 90 minutes in a water-sealed manner to ensure that the dyes in the plant leaves and the cotton blanket can evenly penetrate into the fibers of the dyed and printed real silk target fabric, and complete the transfer process.

[0063] S9. After the dyed and printed real silk target fabric after the transfer in step S8 is cooled, take it out and open it, separate the plastic barrier, the dyed and printed real silk target fabric, the plant leaves and the cotton blanket, wash the dyed and printed real silk target fabric after dyeing to remove excess dyes and mordants, iron it and place it in a cool place to dry naturally.

[0064] The obtained final fabric is as Figure 2As shown, it can be seen from the figure that the completed printed and dyed fabric has a strong dark gray background color, with clear outlines, distinct structures, clear vein characteristics, and strong hues of plant leaves.

[0065] Example 3

[0066] Comparative Example 1: Specifically, as Figure 3 shown, the mordant on the silk fabric is: the weight of ferrous sulfate accounts for 1% of the weight of the target silk fabric for printing and dyeing. The performance effect shows a blackish-gray picture quality, and it is almost impossible to show other colors. The color fixation effect is poor, and the pattern outline is blurred.

[0067] Comparative Example 2: Specifically, as Figure 4 shown, the mordant on the silk fabric is: the performance effect of 5 parts by mass of anhydrous copper sulfate. The picture quality is yellowish-brown, and it is almost impossible to show other colors. The color fixation effect is poor, and the pattern outline is blurred.

[0068] Comparative Example 3: Specifically, as Figure 5 shown, the weight of acetic acid accounts for 5% of the weight of the target silk fabric for printing and dyeing. The performance effect can express yellow, red, green, etc., but the color fixation effect is not good, and the pattern outline is blurred.

[0069] Comparative Example 4: Specifically, as Figure 6 shown, the mordant on the silk fabric is: the performance effect that the weight of potassium alum dodecahydrate mordant accounts for 10% of the weight of the target silk fabric for printing and dyeing + the weight of ferrous sulfate accounts for 1% of the weight of the target silk fabric for printing and dyeing. The picture quality is yellowish-brown, the color fixation effect is good, and the pattern outline is clear, but it is almost impossible to show other colors.

[0070] Comparative Example 5: Specifically, as Figure 7 shown, the mordant on the silk fabric is: the performance effect that the weight of potassium alum dodecahydrate mordant accounts for 10% of the weight of the target silk fabric for printing and dyeing, and the weight of acetic acid accounts for 5% of the weight of the target silk fabric for printing and dyeing. It can hardly express colors, the color fixation effect is not good, and the pattern outline is blurred.

[0071] Comparative Example 6: Specifically, as Figure 8 shown, the mordant on the silk fabric is: the weight of ferrous sulfate accounts for 1% of the weight of the target silk fabric for printing and dyeing. The weight of acetic acid accounts for 5% of the weight of the target silk fabric for printing and dyeing. The overall is blackish-gray, and it is almost impossible to express other colors (purple is anthocyanin, which is not relevant to this experiment). The color fixation effect is good, and the pattern outline is clear.

[0072] Comparative Example 7: Specifically, as Figure 9As shown, the mordant on the silk fabric is as follows: the weight of potassium alum in dodecahydrate accounts for 15% of the weight of the target silk fabric for printing and dyeing, the weight of ferrous sulfate accounts for 2% of the weight of the target silk fabric for printing and dyeing, and the weight of acetic acid accounts for 3% of the weight of the target silk fabric for printing and dyeing. The picture quality is yellowish. Although it can also show red (eucalyptus leaves), but compared with Figure 1 the comparison shows that the green expressiveness is poor.

[0073] Comparative Example 8: Specifically, as Figure 10 shown, the mordant on the silk fabric is as follows: the weight of potassium alum in dodecahydrate accounts for 10% of the weight of the target silk fabric for printing and dyeing, the weight of ferrous sulfate accounts for 0.5% of the weight of the target silk fabric for printing and dyeing, and the weight of acetic acid accounts for 8% of the weight of the target silk fabric for printing and dyeing. All leaf contours are clear and can express red (eucalyptus leaves), green (geranium leaves), dark gray (mulberry leaves), yellow (plane tree leaves), but overall affected by the background color. Compared with Figure 2 the comparison shows that there are deviations. The background color is the extraction of sappanwood.

[0074] Therefore, the proportion in the formula can be adjusted, and the performance effect can also be achieved, but it will affect the color expressiveness.

[0075] Comparative Example 9: Specifically, as Figure 11 shown, the performance effect of the formula of this application on cotton fabric. For Koelreuteria paniculata leaves (large) and Loropetalum chinense var. rubrum leaves (small), although they can also be shown, but compared with Figure 1 the comparison shows that they are not clear enough. There is no background color

[0076] Comparative Example 10: Specifically, as Figure 12 shown, the performance effect of the formula of this application on wool fabric. For the flowers of Rudbeckia hirta, the fruits of Koelreuteria paniculata (dark color), and the leaves of Zelkova serrata (orange-red), although they can also be shown, but compared with Figure 2 the comparison shows that they are not clear enough. The background color is the extract of plane tree leaves.
