Reactive dye printing
Encyclopedia
Reactive dye
printing is a method of printing a dye
or wax
by using mixes thereof to create colors. With a binder and a heat-activated printing additive, images can be permanently bonded to the substrate (typically textiles
, but can include cellulose, fibers, polyester, and even proteins). These reactions are generally heat-activated.
Reactive dye
In a reactive dye a chromophore contains a substituent that is activated and allowed to directly react to the surface of the substrate. Reactive dyes have good fastness properties owing to the bonding that occurs during dyeing....

Dye
A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an aqueous solution, and requires a mordant to improve the fastness of the dye on the fiber....

Wax
thumb|right|[[Cetyl palmitate]], a typical wax ester.Wax refers to a class of chemical compounds that are plastic near ambient temperatures. Characteristically, they melt above 45 °C to give a low viscosity liquid. Waxes are insoluble in water but soluble in organic, nonpolar solvents...

Textile printing
Textile printing is the process of applying colour to fabric in definite patterns or designs. In properly printed fabrics the colour is bonded with the fiber, so as to resist washing and friction...
