Reactive dyes are highly colored organic substances that are used for coloring natural fabrics. Reactive dyes are named as such because of the chemical reaction they undergo during the dyeing process. Unlike other dyes that merely adhere to the fabric’s surface, reactive dyes form a covalent bond with the fibers. This bond is created through a chemical reaction between the dye molecules and the hydroxyl groups in the cellulose fibers of natural fabrics like cotton.
The mechanism of reactive dye is known for its excellent wash and light fastness. It is a preferred choice in the textile industry for achieving high-quality and fade-resistant dyed fabrics.

Sardar Chemicals reactive dyes offer a wide range of vibrant and diverse shades suitable for dyeing various natural fibers, such as cotton, rayon, and linen. The dyes are known for their excellent colorfastness and durability, ensuring the colors remain vivid and bright even after repeated washings.
Sardar Chemicals reactive dyes come in various colors, ranging from soft pastels to bold and intense hues. Whether it’s a subtle and soothing shade for delicate fabrics or a bold and striking color for statement pieces, Sardar Chemicals reactive dyes cater to various design preferences and applications.
Reactive dyes create a strong chemical bond with fibers, resulting in vibrant and long-lasting colors on the fabric.
Reactive dyes offer diverse shades and color options, providing flexibility in dyeing applications.
The covalent bond ensures that colors remain intact even after multiple washes and exposure to sunlight.
Reactive dyes are specifically designed for natural fibers like cotton, linen, rayon, and viscose, making them ideal for dyeing these materials.
Reactive dyes have a high affinity for fibers, which leads to better dye absorption and efficient use of dye materials.
Reactive dyeing consumes a significant amount of water during the process, which can be an environmental concern in areas with limited water resources.
The methods by which reactive dyes can be applied are as follows:
These dyes contain a monochlorotriazine ring and are used for dyeing cotton and other cellulosic fibers with good color fastness.
These dyes have two reactive groups, vinyl sulfone, and monochlorotriazine, improving dye fixation on cellulosic fibers.
