Description

Technical Field

[0001] The invention belongs to the field of fabric printing and dyeing, and specifically relates to a method for developing a specific color system of plant thermal transfer. Background Art

[0002] The colors presented by existing plant thermal transfer basically present the unique color system of the plant. Some plants contain non-coloring tannic acid, so except for the black and gray colors that can be produced by using ferrous sulfate-containing mordants, they generally cannot present colors. Although some plants can present unique colors, when printing and dyeing fabrics, the plants need to present the colors required by the creator, which cannot be achieved by changing the mordant. For this reason, a method for coloring specific color systems of plant thermal transfer is proposed. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a method for developing a specific color system of plant thermal transfer, thereby solving the problems in the prior art.

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0005] A method for developing a specific color system of plant thermal transfer printing comprises the following steps:

[0006] Extract natural plant pigments, boil the plant leaves to be thermally transferred in the natural pigments, and soak them after cooling;

[0007] Clean the target fabrics for printing and dyeing;

[0008] Wash and wring out the cotton blanket;

[0009] Soak the cleaned printing and dyeing target fabric in the mordant for mordant dyeing, and wring it dry after the mordant dyeing is completed;

[0010] Soak the cleaned cotton blanket in the mordant, turn it over, rub it, and then wring it until no water drips, and set it aside;

[0011] Lay the target fabric for printing and dyeing flat after mordant dyeing, and then place plant leaves soaked in natural plant pigments on the surface, and cover the target fabric for printing and dyeing with the plant leaves with a cotton blanket soaked in clean water and wrung out, and press and lay it flat;

[0012] Spread the plastic barrier on the cotton blanket, roll up the plastic barrier, cotton blanket, plant leaves and the target fabric for printing and dyeing from bottom to top with a stick, so that the target fabric for printing and dyeing is located at the outermost layer, and then bundle the rolled target fabric for printing and dyeing;

[0013] Steam the bundled target fabrics to complete the transfer;

[0014] After the transfer-printed target fabric is cooled, it is taken out and opened, and the plastic barrier, the target fabric, the plant leaves and the cotton blanket are separated. The target fabric is washed, ironed and dried.

[0015] Furthermore, the cooking time of the plant leaves in the natural pigment is 20-30 minutes, and the soaking time is more than 5 hours.

[0016] Furthermore, neutral detergent with a pH value of 6-7 is used for cleaning the printed and dyed target fabrics and the cotton blanket.

[0017] Furthermore, the process of soaking the target fabric for printing and dyeing in the mordant is: adding the mordant into clean water, stirring to dissolve, putting in the cleaned target fabric for printing and dyeing, kneading and pressing, and letting it stand, and wringing it dry after the mordant dyeing is completed.

[0018] Furthermore, the mordant used for soaking the target fabric for printing and dyeing is potassium aluminum sulfate dodecahydrate, wherein the weight of the potassium aluminum sulfate dodecahydrate mordant accounts for 20% of the weight of the target fabric for printing and dyeing.

[0019] Furthermore, the clear water temperature is 20-30°C.

[0020] Furthermore, the specific process of soaking the cotton blanket in the mordant is: adding the mordant into clean water, stirring continuously during the adding process; after it is fully dissolved, putting in the cleaned cotton blanket, kneading to make the cotton blanket fully contact with the mordant and soaked evenly, then picking up and wringing out for later use.

[0021] Furthermore, the mordant of the cotton blanket is a ferrous sulfate mordant or a copper gluconate mordant.

[0022] Furthermore, the bundled printing and dyeing target fabric is steamed in water for 90-120 minutes.

[0023] A printed and dyed fabric is prepared by adopting the above-mentioned plant thermal transfer specific color system color development method.

[0024] Beneficial effects of the present invention:

[0025] The final color tone effect of plant thermal transfer is unstable. By adopting the method of the present invention, plant thermal transfer will not be affected by factors such as mordant formula, plant species, plant growing place, plant growing time, etc. After the product is processed by the present invention, it can produce a specified color tone and the effect can be replicated.
