Disperse ink---distributed digital printing


At present, more than 50% of China's printing inks are disperse dye inks, which are used for printing of chemical fiber fabrics such as polyester fibers. Disperse dyes are a kind of water-soluble, low-concentration, and the main particles are highly concentrated in water by means of dispersing agents. A nonionic dye present in a dispersed state.


Reactive ink---active digital printing


Reactive ink accounts for about 29%, mainly used for silk and cotton fabric printing; reactive dyes, also known as reactive dyes. A type of dye that chemically reacts with fibers during dyeing. These dyes contain a gene that chemically reacts with the fiber. The dye reacts with the fiber during dyeing, forming a covalent bond between the two, which becomes a whole, which improves the washing and rubbing fastness. The active fuel molecule includes two main components of the parent dye and the active group, and the group reactive with the fiber is referred to as an active group. At present, it is mainly used on woven and knitted fabrics such as cotton, general hemp, silk, or fabrics with higher composition.


Acidic ink---acid digital printing


Acidic ink has a small specific gravity of about 7% and is used for fabric printing such as wool and nylon. Acidic inks are a class of water-soluble inks with structurally acidic groups that are dyed in an acidic medium. Most of the acid inks contain sodium sulfonate, which is soluble in water, bright in color and complete in chromatography. Mainly used for dyeing wool, silk and nylon, but also for leather, paper, ink and so on. Generally no coloring power is applied to cellulose fibers.
