Reactive dye print is by far the top choice for dyeing cotton, and other cellulose fibers at home and at the art studio.
So, what exactly is Reactive dye print? Reactive dye print is highly colored organic substance which is basically used for dyeing textiles.

These reactive dyes are the most permanent of all dye types.
The importance of printing on fiber substance is largely due to the introduction of pigments and reactive dyes. Reactive prints are the highest requirement among the community due to its coloristic and fastness properties.

A lot of technological innovations have been bought into the reactive dye print process, thus making it more technically improved, visually attractive and economical nature.
Given the higher level of performance expected from a finished product, it is important to choose the right printing system.

Process of reactive dye print


The reactive dyeing process is one of the most crucial methods of dyeing.
Due to a chemical reaction, the reactive dyes attach themselves to their substrates.

This creates a covalent bond between the molecule of dye and that of the fiber. The dyestuff then becomes a part of the fiber.
The absorption property of dyestuffs doesn’t let the colors to get removed when clothes are washed.

Theoretically, reactive dye print is a method of printing using a wax or dye.
By using these mixes, colors are created. Reactive dye print is water soluble dyes.

They have sulphonic acid groups and reactive groups like dichloride or monochloro tniazinyl groups or sulplato ethyl sulphone groups. When a functional group of the fiber gets mixed with the alkali such as hydroxide, sodicens carbonate, silicate, a chemical reaction occurs. This is the reason why these dyes are called as reactive dyes.

When colored patters and designs are decorated with a finished fabric, it is called ��printing’. In a proper printed fabric, or cloth, the color is attached to the fiber, as it can’t get affected by washing or any friction.
On the printed fabric, the design outline is sharply identified on the outer side, and this design does not penetrate to the back of the clothing. But, the design can show up on the reverse side of the thin fabrics. The dyes used for printing generally include naphthol, vat, and disperse colors which have good fastness properties. The pigments used in the dye, are

The dyes used for printing generally include naphthol, vat, and disperse colors which have good fastness properties. The pigments used in the dye, are important part of the printing process of fabric. Pigments are one of the fastest known colors and are effective for medium and light shades. It may get rubbed off if dark shades were used.


Advantage of reactive dye print


  • It helps in ensuing steaming or baking fixing to progress processing speed and cut the time dye hydrolysis, to get the high fixation rate and color fastness
  • It reduces the over-run wastage and eliminates the design and process distortions associated with printing
  • Reactive dye print is cleaner, safer and less wasteful, and less hazardous for the environment
  • It lowers the need for inventory

As the reactive dye in the inks actually reacts with the fiber, it results in excellent wash fastness. The print formed has a high level of permanency, and it serves the customers better for a long period of time.
