Description

Technical Field

[0001] The invention relates to the technical field of dyeing technology, and more specifically to a double dyeing process for blended fabrics. Background Art

[0002] Blended fabrics, that is, blended chemical fiber fabrics, are textile products made by mixing chemical fibers with other natural fibers such as cotton, wool, silk, and linen. They have both the style of polyester and the advantages of cotton fabrics, such as polyester-cotton cloth, polyester-wool gabardine, etc. Double dyeing and printing technology is a dyeing technology, which corresponds to single dyeing. It refers to dyeing two different components of the dyed fabrics twice, which can be the same color or different colors. This process is mostly used for dyeing blended fabrics.

[0003] The double dyeing process used for blended fabrics in the prior art has a general color fixing effect and is prone to color fading during later use, thereby affecting the use effect of the blended fabrics and being unfavorable for promotion and use.

[0004] Therefore, a double dyeing process for blended fabrics is urgently needed to solve the above problems. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a double dyeing process for blended fabrics. The color fixing effect of the present invention is good, and it is not easy to fade during later use, thereby ensuring the use effect of the blended fabrics. At the same time, the softness and wrinkle resistance of the blended fabrics are improved, which facilitates the promotion and use of the present invention to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a double dyeing process for blended fabrics, comprising the following steps:

[0007] Step 1: Select suitable blended fabrics, then wash the blended fabrics with clean water and drain them, and then wash the blended fabrics again with clean water to ensure that the blended fabrics are clean and remove impurities and oil stains on the surface;

[0008] Step 2: Dry the blended fabric after the second cleaning, and then iron the blended fabric after drying to ensure that the blended fabric is flat;

[0009] Step 3: Use chlorine bleaching to treat the blended fabric after ironing, using the oxidation effect of sodium hypochlorite to destroy the structure of dyes and stains, so that the blended fabric is clean, faded and bleached;

[0010] Step 4: Put the blended fabric after chlorine bleaching into the dye for dyeing. After dyeing, take out the blended fabric and dry it.

[0011] Step 5: Prepare a color fixing solution, use water as the solvent, add the color fixing agent into the water and mix thoroughly, then add the blended fabric that has been dyed once into the solution, ensure that the blended fabric is in full contact with the color fixing agent, and perform a color fixing treatment;

[0012] Step 6: Dry the blended fabric after the color fixing treatment to ensure the color fixing effect;

[0013] Step 7: Select the dye for secondary dyeing, and then use the spraying method to perform secondary dyeing on the blended fabric after the primary color fixation. After dyeing, take out the blended fabric and perform drying treatment;

[0014] Step 8: The blended fabric after secondary dyeing is treated with high temperature for secondary color fixation;

[0015] Step 9: Choose a softener that will not react adversely with the primary dyeing dye and the secondary dyeing dye, immerse the secondary color-fixing blended fabric in the softener, and allow the softener to fully penetrate the blended fabric;

[0016] Step 10: After softening, take out the blended fabric and dry it to fix the softener on the fabric, thus achieving a lasting softening effect;

[0017] Step 11: Select an anti-wrinkle agent with no adverse reactions, spray the anti-wrinkle agent evenly and fully on the blended fabric, and then use heating and pressurization to better fix the anti-wrinkle agent in the fiber and improve the shape stability of the fabric;

[0018] Step 12: After the heating and pressurizing treatment, wait for the blended fabric to cool naturally and then finish it to ensure the durability of the anti-wrinkle effect;

[0019] Step 13: Check the quality of the double-dyed, softened and wrinkle-resistant fabrics to ensure they meet the standards.

[0020] Technical effects and advantages of the present invention:

[0021] The invention first selects a suitable blended fabric, then cleans the blended fabric with clean water and drains it, then cleans the blended fabric twice with clean water to ensure that the blended fabric is clean, removes impurities and oil stains on the surface, dries the blended fabric after the second cleaning, and then irons the blended fabric after drying to ensure that the blended fabric is flat, adopts chlorine bleaching to treat the ironed blended fabric, utilizes the oxidation effect of sodium hypochlorite to destroy the structure of dyes and stains, so that the blended fabric is clean, faded and bleached, puts the blended fabric after the chlorine bleaching into the dye for primary dyeing, after dyeing, takes out the blended fabric and performs drying treatment, prepares a color fixing solution, adopts water as a solvent, adds a color fixing agent into the water and fully mixes it, then adds the blended fabric that has been dyed once into the solution to ensure that the blended fabric is fully in contact with the color fixing agent, performs a color fixing treatment once, dries the blended fabric that has been treated with the color fixing once to ensure a color fixing effect, selects a dye for secondary dyeing, and then adopts a spraying method to perform secondary dyeing on the blended fabric that has been fixed once, after dyeing, takes out the blended fabric The blended fabric after secondary dyeing is treated with high temperature for secondary color fixation, a softener that will not react adversely with the dye of primary dyeing and the dye of secondary dyeing is selected, and the blended fabric for secondary color fixation is immersed in the softener to fully penetrate the blended fabric.
