Dye particles have a size ranging from to microns, generally contain NH2, substituted NH 2, or OH groups in the structure, and get attached with the fiber through Hbond and van der Waals force. Dyes are retained by the fiber by physical forces. Fastness properties are very high in polyester except in certain cases.

The application of membrane technology in dyeing wastewater is not common because the service life of membrane is short and it is easy to be polluted (Shamraiz et al., 2016). From the literature, adsorption is the most commonly used method to treat dyeing wastewater due to its simple operation process, low cost and ideal effect(Mu and Wang, 2016).

Dyeing and processes are valueadded treatments for most textile materials. A dyeing process is the interaction between a dye and a fibre, as well as the movement of dye into the internal part of the fibre. Generally, a dyeing process involves adsorption (transfer of dyes from the aqueous solution onto the fibre surface) and diffusion (dyes diffused into the fibre).

Pigment dispersion is the process of suspending insoluble pigments in a liquid medium, typically water or organic solvent, so that they can be used in inks paints and coatings. Traditionally, pigment dispersion is comprised of three main steps; wetting, deagglomeration, and stabilization. These three steps are outlined in further detail below.

1. Introduction. The solubility of disperse dyes in water is low. In the disperse dyeing process for synthetic fibers, adding the dispersants can maintain the dispersion stability of the dyes in water and ensure that the dyes can be stably adsorbed to the fiber surface in the form of nanodispersed particles.

Indigo production from plants is based on the conversion of native indigogenic precursors. Before the discovery of indigo precursors, it was admitted that indigo existed in reduced form in the dye plants and during its extraction, oxygen converted it into blue indigo [40].In 1855, indican or indoxylβDglucoside (Fig. 2), was the first precursor detected from Isatis tinctoria by Schunck [41].
