Printing on fabrics has been an art form that dates back centuries, with a rich history of creativity and innovation. From traditional block printing to modern digital techniques, the choice of ink plays a crucial role in achieving vibrant, long-lasting designs on fabrics. In this blog post, we will explore the various types of inks available for fabric printing, each with its unique characteristics and applications.
Pigment Inks
Pigment inks are known for their exceptional colour, fastness, and durability. They consist of tiny solid pigment particles suspended in a liquid carrier, making them ideal for fabric printing. These inks bond well with the fabric fibres, resulting in a design that resists fading, even after multiple washes. Additionally, pigment inks exhibit excellent coverage, making them suitable for light and dark fabrics. Their versatility and minimal bleeding make them a popular choice for printing on various textiles, including cotton, linen, and canvas.
Reactive Dye Inks
Reactive dye inks are specifically designed for natural fibres like cotton, silk, and viscose. They create a strong chemical bond with the fabric, producing vibrant, long-lasting designs. The reactive dye process involves a chemical reaction between the dye and the material, ensuring the ink becomes an integral part of the textile. It also allows for a wide range of colours and intricate designs. However, it is essential to consider the extra care required to set the dye properly and prevent colour bleeding during the initial washes.
Acid Dye Inks
Acid dye inks are primarily for printing on protein-based fibres such as silk, wool, and nylon. The ink’s acidity helps bond with these fibres, resulting in vivid, colourfast prints. Acid dye printing offers excellent colour reproduction and allows for detailed designs, making it popular in the fashion industry for scarves, ties, and high-end apparel. It is important to note that acid dye prints may require gentle handling and cold water washing to preserve their brilliance over time.
Disperse Dye Inks
Disperse dye inks are specifically designed for synthetic fibres like polyester and nylon. Unlike other types of inks, disperse dye inks are a type of sublimation ink that transition from solid to gas during the printing process. It allows the dye to penetrate the synthetic fibres deeply, resulting in a permanent and wash-resistant design. Due to its excellent colour vibrancy and durability, sublimation printing is widely used in sportswear, custom activewear, and polyester-based home textiles.
Water-Based Inks
Water-based inks are environmentally friendly and widely used for fabric printing due to their non-toxic nature. They contain water as the primary solvent, making them easy to clean up and suitable for direct printing on various fabrics. Water-based inks are popular for DIY projects, as they do not require any special equipment or setup. However, they may not be as colourfast as other ink types, especially on dark fabrics. Pre-treating the fabric or using a fabric medium can enhance its durability.
Solvent-Based Inks
Solvent-based inks are primarily used in industrial fabric printing, particularly for synthetic materials like vinyl and PVC-coated fabrics. These inks contain organic solvents as the carrier, which evaporates during drying, leaving the pigment on the fabric. Solvent-based inks offer excellent adhesion and resistance to water and UV light, making them suitable for outdoor applications such as banners and signage.
