Dye (pigment) structure, the dye structure is basically divided into three parts "chromophore root group" "reaction (bonding) root group" "connecting root group"


Chromophore: Light (photons) can be irradiated on this chemical structure (photons hit the chromophore, resonate and emit a specific wavelength) to have a color feeling.


Reaction (bonding) root group: It can react with the fiber to fix the dye. This is called the reaction root group of the dye. Different fibers, the reaction bonding root group is different, such as cotton, or nylon/or acrylic dyes. Different reactive root groups.


Connecting the root group: It is bounded between the chromophore root group and the reaction root group to bridge the chromophore root group and the reaction root group, so that the chromophore root group and the reaction root group become one.
