Understand The Dye Application Technology Of Fabric Hanging Dyeing Process

 

Hanging dyeing is a traditional dyeing process in which designated dyes or pigments are coated on fabrics. This process usually requires the use of a hanging container containing fabrics to be dyed and dyes or pigments.

Dancing dyeing is a kind of dyeing technology on the surface of fabric. Its principle is to absorb dyes into the fabric through the siphon effect by using the vibration and flow of yarn to form a gradual effect.

In hanging dyeing, the dye is dispersed into the fabric. Through the vibration and flow of the yarn, the dye gradually moves to the surface of the fabric and penetrates into the fabric fibers. In this process, the contact area between the dye and the yarn is constantly changing, which can form different dyeing effects, such as different color spots, blocks or shades.

Hanging dyeing technology can be applied to the dyeing of women's dresses, T-shirts, curtains and other fabrics. Its advantages are uniform dyeing, no damage to the fabric, and convenient color fixation.

Because hanging dyeing is a dyeing method that disperses dyes of different colors in water and lets pigments float on the water to achieve a gradual change effect. This method can make dyes diffuse freely on the surface of water to form beautiful color effects.

Hanging dyeing is often used in the dyeing of jeans. Indigo is one of the commonly used dyes, which can be used to render the color of denim in hanging dyeing.

Hanging dyeing can use a variety of different dyes, such as blue, purple, red, yellow, etc., to choose the most suitable color and effect.

It should be noted that the proportion of dye and water should be controlled to achieve the best dyeing effect. At the same time, it also requires some dyeing technologies, such as rendering, halo dyeing, etc., to create more colorful color effects.

Hanging dyeing is an operation to fade or dye the fabric under the action of specific dyes. The following are some dyes that may be suitable for hanging dyeing:

The following dyes are usually used for hanging dyeing of cotton fabrics:

Reactive dyes: Reactive dyes can be used to hang and dye cotton fabrics, because they can form chemical reactions with cotton fibers, thus improving the color fastness and environmental protection. For example, AR-101, AR-103, AR-121, AR-125, etc. are commonly used reactive dyes.

Direct dyes: Direct dyes can react directly with cotton fibers, thus no active metabolism is required. For example, Dy-60, Dy-65, Dy-70, etc. are dyes that can be directly hanged.

Pigment dyes: Pigment dyes can form a composite with cotton fibers, thus increasing the fastness of colors, and also making dyed cotton fabrics more soft and comfortable. For example, L-111, L-121, L-141, etc. are commonly used paint dyes.

Acid dyes: such as acid dyes used in polyester fabrics, such as polyester acid, polyester oxygen, acid violet 2113, etc. They can react with enzymes on the fabric to produce fading effects.

Alkaline dyes: Alkaline dyes used for polyester fabrics, such as alkaline orange 6 and alkaline blue, can react with enzymes on the fabric to produce fading effect.

Reducing dyes: such as the reducing dyes used in cotton polyester blended fabrics, such as azo dyes used in even numbers, azo dyes used in acrylic fabrics, etc. They can react with enzymes on the fabric to produce fading effects.

Disperse dye: Disperse dye is a water-soluble dye that can be dissolved in water and pass through the fabric to form a dyeing area. They are usually used for weaving fiber fabrics, such as polyester fiber, nylon, etc.

Each dye has its own applicable scene and scope. Which dye is used for hanging depends on the type of fabric dyed and the desired effect. When selecting dyes, it is recommended to consider comprehensively the fabric type, the required dyeing effect and the performance characteristics of dyes.

The dyes required for hanging dyeing vary depending on the specific product and production process. Therefore, it is recommended to select dyes suitable for the product and production conditions.

Hanging dyeing refers to dyeing on ready-made clothes, and the proportion and area of dyeing will vary with different dyeing methods and materials. The following are some common hanging dyeing methods and their possible coloring proportions and areas:

Monochrome dyeing: Monochrome dyeing is usually carried out at a certain place of clothing, and its area and proportion will vary depending on the dyeing method and dyeing materials. Some commonly used monochrome dyeing materials include cotton, polyester, wool, etc. Generally speaking, the area ratio of monochrome dyeing is recommended to be between 1% and 5%, depending on the dyeing method and materials.

Mixed color dyeing: Mixed color dyeing is to mix different colors to create a stronger color effect. In mixed color dyeing, the area proportion of each color will also vary depending on the dyeing method and materials. In general, it is recommended that the proportion of each color should be between 1% and 5%, depending on the dyeing method and material

Multi color dyeing: Multi color dyeing is to mix materials of different colors to create a brighter color effect. In multi-color dyeing, the area ratio of each color should also be determined according to the dyeing method and dyeing materials to achieve the best dyeing effect.

When carrying out hanging dyeing, it is recommended to carry out tests according to specific dyeing needs and dyeing materials to determine the best dyeing proportion and area. At the same time, pay attention to the washing and drying methods after hanging dyeing to ensure the dyeing effect and the service life of the clothes.

The following are some methods of dye suspension and color fixation:

Use of color fixing agent: the color fixing agent can promote the color fixation of fabric fibers, which can be added to the solution of suspension dyeing or treated with color fixing agent after dyeing.

Adding color fixing agent during dyeing: add color fixing agent to the dyeing solution, and then dye at a certain temperature. This method is suitable for dyeing with light fixation.

Color fixing treatment before dyeing: add color fixing agent to the fabric, and then wash and dry the color fixing to make the fabric fiber color fixing better.

Amount of fixing agent added: different fixing agents and dyes have different effects on the fixing effect. Usually, the amount of color fixing agent needs to be adjusted according to the fiber type of the fabric and the required color fixing depth.

Mixing of color fixing agents: mixing a variety of color fixing agents to increase the effect of color fixing and the sense of color hierarchy.

Influence of temperature and light: temperature and light also have a great influence on the effect of color fixation, which needs to be properly adjusted during the dyeing process.

The above are some better color fixing methods, and one or more of them can be selected according to the actual situation.

Try the following simple operation procedures:

Prepare fabric: hang the fabric in the hanging container and select the dyes or pigments to be dyed.

Washing fabric: immerse the fabric in clean water for a period of time, and then gently rub it with hands or washing machine. This allows the fabric to remove impurities and stains.

Dyeing: put the fabric into a hanging container, add appropriate dyes or pigments, and stir evenly. Then take the fabric out of the hanging container and lay it flat on the operating platform for dyeing.

Fixation: In the dyeing process, add appropriate fixing agent or fixing agent solution, and stir evenly. Fixing can make dyes or pigments form a stronger coating on the fabric.

Washing and drying: soak the dyed fabric in clean water for a period of time, then gently rub it with hands or a washing machine, and finally dry it in the sun or in a ventilated drying room.

In actual operation, the steps of hanging dyeing may be different, but the concentration of dyes or pigments, mixing ratio, pH value of water and other parameters need to be carefully controlled throughout the process to ensure that the fabric gets the desired color and color fixing effect.
