Practical Textile The acrylic fabric dyeing Process is a quick, effective, and affordable way to dye your fabric. There are many different acrylic dye colors available, so you can find the color that best suits your needs. The dye will also resist fading and discoloration.
Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average Weight of 100,000 about 1900 monomer units. Acrylic fiber must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate. The acrylic fabric dyeing process is also in an acidic medium.
Properties of acrylic fiber:
- Acrylic fiber: Group of Acrylonitrile, acrylic, Polyacrylonitrile,
- Fabric composition: Synthetic polyacrylonitrile polymer.
- Moisture-wicking finish – High
- Stretch ability _- High
- Pilling / Rubbing – High
- Producing country – the USA
- Best Exporting / producing – China.
End use:
Sweaters, Wood hair, boots lining hats, Gloves, Athletic wear. Carpeting, Blankets, roller brushes, Upholstery, Area rugs, Protective clothing, wigs, and Hair Extensions.

Attention: Here Temperature is the most important factor.
Mechanism of Basic Dye with Acrylic Fabric Dyeing Process:
Basic dyes, also known as cationic dyes, have a positive charge that allows them to easily bind to negatively charged acrylic fibers. This mechanism of dyeing involves the formation of an ionic bond between the basic dye and the fiber.
The basic dye molecules penetrate the fiber and attach to the fiber’s amino groups, resulting in strong color retention. The acrylic fabric dyeing process typically involves adding the basic dye to an acidic medium, which helps to increase the affinity between the dye and the fiber and ensure proper fixation of the color onto the fabric.
Conclusion:
In conclusion, acrylic fabric dyeing is a process that can be used to create a variety of different colors and patterns on fabric. Several different methods can be used to dye acrylic fabric, and each method has its own advantages and disadvantages. The best way to find the right method for dyeing your fabric is to experiment with different methods until you find one that you are happy with.
