Description

Technical Field

[0001] The invention belongs to the field of natural material fabric printing and dyeing, and specifically relates to a fabric dyeing and printing method based on plant thermal transfer. Background Art

[0002] Fabric printing and dyeing refers to the process of attaching dyes or other colorants to fabrics through various technical means to give them specific colors and patterns. This process not only gives the fabric a beautiful appearance, but also plays an important role on many levels. Fabric printing and dyeing in the existing technology generally uses chemical raw materials as mordants, or contains heavy metal components, or cannot produce specified colors; machine batch printing and dyeing patterns are fixed and repetitive, lacking flexibility. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a fabric dyeing and printing method based on plant thermal transfer, which solves the problems in the prior art.

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

[0005] A fabric dyeing and printing method based on plant thermal transfer comprises the following steps:

[0006] Clean the target fabrics for printing and dyeing;

[0007] Wash and wring out the cotton blanket;

[0008] Soak the cleaned target fabric for printing and dyeing in potassium titanium oxalate mordant for mordant dyeing. After the mordant dyeing is completed, wring it out for later use;

[0009] Soak the cleaned and wrung-out cotton blanket in a mordant of potassium aluminum sulfate dodecahydrate for mordant dyeing, and wring it out after the mordant dyeing is completed;

[0010] Lay the mordanted target fabric flat, then place plants on the surface, cover the mordanted cotton blanket on the target fabric with the plants, and press and lay it flat;

[0011] Spread the plastic barrier on the cotton blanket, roll up the plastic barrier, cotton blanket, plants 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 on the outermost layer, and then tie up the rolled target fabric for printing and dyeing;

[0012] Steam the bundled target fabrics to complete the transfer;

[0013] After the transfer-printed target fabric is cooled, it is taken out and opened, and the plastic barrier, the target fabric, the plant and the cotton blanket are separated, and the target fabric is washed, ironed and dried.

[0014] Furthermore, a neutral detergent with a pH value of 6.4 was used to clean the printed and dyed target fabrics and the cotton cover blanket.

[0015] Furthermore, the process of soaking the target fabric for printing and dyeing with potassium titanium oxalate mordant is as follows: adding the potassium titanium oxalate 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.

[0016] Furthermore, the weight of the potassium titanium oxalate mordant accounts for 5-6% of the weight of the target fabric for printing and dyeing.

[0017] Furthermore, the clear water temperature is 20-30°C.

[0018] Furthermore, the process of soaking the cotton blanket in the mordant is: adding potassium aluminum sulfate dodecahydrate mordant into clean water, stirring to dissolve, rubbing and pressing, and letting it stand, and wringing it dry after the mordant is completed.

[0019] Furthermore, the weight of the potassium aluminum sulfate dodecahydrate mordant accounts for 20% of the weight of the cotton blanket.

[0020] Furthermore, the clear water temperature is 50-60°C.

[0021] Furthermore, the bundled printing and dyeing target fabric is steamed in water for 90-120 minutes.

[0022] A printed fabric is printed and dyed by using the above-mentioned fabric dyeing and printing method based on plant thermal transfer.

[0023] Beneficial effects of the present invention:

[0024] 1. The present invention uses a plant thermal transfer process to transfer the image of the plant to the pre-mordanted target fabric using the heat and humidity of water vapor, and uses a specific mordant to mordant the target fabric, so that the final printed natural plant presents an orange-yellow color tone on the target fabric;

[0025] 2. The color of the target fabric after dyeing presents a bright orange-yellow color, with natural and soft color, high color fastness, and is not easy to fade. It realizes environmentally friendly printing and dyeing, improves the dyeing quality, and enhances the color controllability of printing and dyeing of natural material fabric products. The color tone is not affected by factors such as plant species, plant growing area, plant growing season, and plant planting soil properties. BRIEF DESCRIPTION OF THE DRAWINGS
