Pigment in Fabric Dyes - Fabric Dye Powder Uses in 2024

While choosing fabric dyes, consider the color, price, environmental protection, etc.

1. Color.

First of all, choose a color based on the purpose, environment and atmosphere. Different colors have different meanings. For example, white represents purity, while red represents enthusiasm.

2. Price.

Prices of fabric dyes are closely related to color, quality, etc. Choose fabric dyes based on the budget, quality requirements, etc.

3. Environmental protection.

With an increasing focus on environmental protection, environmentally friendly fabric dyes have received widespread attention. Environmentally friendly fabric pigments are conducive to environmental protection and pollution reduction. They are indispensable to improve the living standards of people.

Conclusion: Fabric dyes are special pigments, which are customizable and environmentally friendly, with full and lasting colors. Choose fabric pigments based on the color, price, environmental protection and other factors in order to better meet your needs.

1. Pretreatment
Conduct pretreatment before using fabric pigments. First, clean fabric with detergent to remove oil stains and impurities from the surface. Then, carry out soaking and bleaching with acidic or alkaline solution, to remove colored substances and impurities from fabric.

2. Dyeing
Fully mix fabric pigments and additives into paste. Then, soak fabric and stir the solution, until fabric is colored evenly. The soaking time is usually 30 minutes to 1 hour.

3. Color fixing
Conduct color fixing to dyed fabric, to ensure the color fastness. Generally, there are two methods: drying by heating, and fixing with high-temperature steam. In the process of drying by heating, keep fabric at about 150°C in an oven, so that pigments are fixed on the fabric surface. In the process of fixing with high-temperature steam, heat fabric to about 180℃ in a heat press, to fix the color in the presence of high-pressure steam.

These are basic methods for the use of fabric pigments. They should be adjusted and improved based on the material, color, shape, purpose and other factors of fabric.

I. Characteristics of fabric pigments
Fabric pigments are special pigments for fabric coloring. Different from fabric dyes, fabric pigments are evenly adhered onto the fabric surface, instead of chemical reaction to fabric.

Fabric pigments are characterized by bright color, high color fastness, environmental friendliness, and convenient use. They are suitable for dyeing in small batches. They are widely applied in clothing, shoes and hats, bags, ornaments, etc.

II. Advantages of fabric pigments
1. Full and lasting color. Fabric pigments are securely bonded with fabric at high temperature and pressure, with lasting coloring effects. The color of fabric will not fade or become lighter after cleaning, friction, exposure to sunlight, etc.

2. Customizable. Fabric pigments can be customized as needed. Customers can choose suitable products based on the color, gloss, softness and other parameters.

3. Environmental protection. Fabric pigments are composed of chemical substances, which are compliance with environmental protection standards. Due to no hazardous substances, fabric pigments are not harmful to the human body and environment.

There are two main methods for fabric coloring. In the widely applied method (conventional dyeing), fabric is mainly treated in chemical dye solution. In the other method, paint is treated into tiny insoluble colored particles, which are adhered to fabric (except for dyeing of raw materials of fabric).

Dyes are complex organic substances. They are divided into various types.
1. Acid fabric dyes. They are mostly suitable for protein fibers, nylon fibers and silk. They feature bright color, excellent fastness in dry cleaning, but poor washing fastness. They are widely applied in nature yarn dyeing.

2. Cationic fabric dyes (alkaline dyes). They are suitable for acrylic, polyester, nylon, cellulose and protein fabrics. They are characterized by bright color. They are suitable for artificial fibers. But they have poor washing fastness and light fastness for natural cellulose and protein fabrics.

3. Direct fabric dyes. They are suitable for cellulose fabrics. They have poor washing fastness and light fastness. However, modified direct dyes have better washing fastness.

4. Disperse fabric dyes. They are suitable for viscose, acrylic, nylon and polyester fabrics. Their washing fastness vary from each other. Disperse dyes have high washing fastness for polyester but low washing fastness for viscose.

5. Azo fabric dyes (naphthol dyes). They are suitable for cellulose fabrics. Due to bright colors, they are more suitable for gorgeous fabrics.

6. Reactive fabric dyes. They are applied mostly in cellulose fabrics and little in protein fabrics. They are characterized by bright color and high light fastness, washing fastness and friction resistance.

7. Sulfur fabric dyes. They are suitable for cellulose fabrics. They are characterized by dark color (mainly dark blue, black and brown), high light fastness, high washing fastness, and poor chlorine bleaching fastness. Fabrics made with sulfur dyes are prone to damage in long-term storage.

8. VAT fabric dyes. They are suitable for cellulose fabrics. They have high light fastness, washing fastness and also resistance to chlorine bleaching and oxidation bleaching.

9. Pigments. They are suitable for all fabrics. Instead of dyeing, resin pigments are adhered to fabrics, so dark fabrics are hard. However, accurate topping can be achieved. Most of pigments have high light fastness and washing fastness, especially those in medium and light colors.
