Reactive ink printing is the most preferred choice for inking cotton and other cellulose fibers at home and in the art studio.
So, what exactly is reactive ink? Reactive ink printing is a highly colored organic substance mainly used for inking textile products. These reactive inks are the most permanent of all types of ink.
The importance of the application of pressure to the fiber material is largely due to the occurrence of pigments and reactive inks. Reactive prints are the highest requirement in the society due to their coloration and fastness properties.
Many technological innovations have been purchased in the reactive ink printing process, thus providing a more technically advanced, visually attractive and economical structure. Given the high level of performance expected from a finished product, it is important to choose the correct printing system.
Reactive ink printing process
Reactive inking is one of the most important staining methods. Because of a chemical reaction, reactive inks bind themselves to their substrates.
This forms a covalent bond between the ink molecule and the fiber molecule. The inkstuff then becomes part of the fiber. The absorption property of inkstuffs does not allow removal of colors when clothes are washed.
Theoretically, reactive ink printing is the method of printing using wax or ink.
Using these blends, colors are created. Reactive ink printing is water soluble inks.
They have sulfonic acid groups and reactive groups such as dichloride or monochloro triazinyl groups or sultrate ethyl sulfone groups. When a functional group of fibers is mixed with alkali, such as hydroxide, alkali, carbonate, silicate, a chemical reaction occurs. This is why these inks are called reactive inks. When colored patter and designs are embellished with a finished fabric, it is called printing. In a suitable printed fabric or fabric, the color is added to the fibers as it cannot be affected by washing or rubbing.
In the printed fabric, the design outline is sharply defined on the outside and does not penetrate the back of the garment. However, the design may appear at the back of thin fabrics. Inks used for printing usually contain naphtha, barrel and disperse colors with good fastness properties.
Inks used for printing usually contain naphtha, barrel and disperse colors with good fastness properties. Pigments used in ink are an important part of the printing process of the fabric. Pigments are one of the fastest known colors and are effective for medium to light tones. Dark shadows can be rubbed if used.
Advantage of reactive ink printing
• To achieve high fixing speed and color fastness, it helps in steam or cooking fixing to increase processing speed and time to cut off ink hydrolysis.
• Reduces wasting overtime and eliminates print-related design and process distortion.
• Reactive ink pressure is cleaner, safer and less hazardous for less waste and environment
• Reduces inventory need
