Fabric dyeing chemicals are an essential component in the textile industry, helping to create colors and enhance the aesthetic value of fabric products.

Each fabric type has different chemical properties, requiring suitable dyeing chemicals to ensure colorfastness, prevent color bleeding, and avoid damaging the fabric structure. According to a study by Textile Chemistry Review, over 80% of textile products worldwide use synthetic dyes. However, the trend of using environmentally friendly, non-toxic dyes is growing strongly.

1.2. Common Dye Types in the Textile Industry

Each fabric has its own chemical characteristics, so choosing the right fabric dye is a decisive factor for colorfastness, coverage, and color stability. Here are the most common dye types in the textile industry, classified by their properties and application on different fabric types.

Reactive Dyes: This type of dye forms a strong chemical bond with the cellulose fibers in cotton, viscose, and linen, making the color durable and resistant to fading even after many washes. This dye penetrates deep into the fabric fibers through a reaction with the hydroxyl (-OH) groups of cellulose, creating a strong bond between the dye and the fiber.
- Pros: High colorfastness, good fade resistance, and a rich color palette.
- Cons: The dyeing process is complex, requiring an alkaline environment to fix the color.
Acid Dyes: This type of dye can form an ionic bond with the amine (-NH₂) groups on the fabric fibers, helping the color adhere firmly without damaging the fiber structure.
- Pros: Vibrant colors, good water solubility, and easy to control during the dyeing process.
- Cons: Easily fades in strong sunlight or when exposed to alkaline chemicals.
Direct Dyes: Direct dyes are often used for cotton, viscose, and rayon fabrics, adhering to the fibers through Van der Waals forces and hydrogen bonds with cellulose. Without needing a fixative or special treatment, direct dyes easily penetrate the fibers by simply boiling them in water.
- Pros: Easy to use, simple dyeing process, and low cost.
- Cons: Low colorfastness, easily fades with frequent washing or exposure to sunlight.
Disperse Dyes:Disperse dyes are an ideal choice for dyeing polyester, acrylic, and acetate fabrics due to their ability to penetrate non-absorbent fibers. With their ultra-small molecular size, these dyes are insoluble in water and instead attach to the fabric fibers through a diffusion process at high temperatures (above 120°C).
- Pros: Durable colors, fade-resistant to washing, and high friction resistance.
- Cons: Requires high temperatures for the dye to penetrate, and the dyeing process is more complex than other types of dyes.

Printing on cotton fabric not only requires suitable ink but also an appropriate printing method. Here are some common printing methods:

Screen Printing: This method uses a screen and a squeegee to press ink through the screen onto the fabric. Screen printing allows for sharp, colorfast prints and can be used on large areas.
Direct to Garment (DTG) Printing: This is a method of printing directly onto the fabric with a digital printer, without a screen like in screen printing. This method supports printing complex, multi-colored images and is suitable for small, custom orders. DTG printing requires pre-treating the fabric for better ink adhesion, and the initial investment cost for machinery is quite high.
Heat Transfer Printing: This is an indirect printing method where the image is printed on transfer paper. Then, heat is applied to transfer the ink from the paper to the fabric. This method is easy to perform and is suitable for complex designs. The colorfastness of the printed image may not be high if not done correctly.
