Printing of polyester fabric with disperse dye

Theory: Textile printing is one kind of localized dyeing that is dyes or pigments are applied or discontinuously to produce various design on the fabric with a motif is one more colors and thickness is thickness which imparts stickness and plasticity to the print paste. So that it may be capable of maintaining the design out lines.

Printing of cotton fabric with reactive dye

Theory: Now-a-days reactive dyes are very popular for textile coloration because of its some specific properties like colorfastness. Then textile printing is one kind of localized dyeing that is dyeing that its dyes are pigments are applied locally or discontinuously

Dyeing of cotton fabric with sulpher dye

Theory: Water insoluble dyes have to be converted into water soluble from (leuco from). Sulpher dye is a insoluble dye. Then lecuo from is colorless from with an alkaline liquor. This color returns after oxidation.  This conversation (insoluble soluble) is carried out by dilate aqueous solution of sodium sulphide.

Dyeing of cotton fabric with azoic dye

Theory: azoic dye are not ready mode dyes like reactive dyes. The insoluble azoic colors are synthesized inside the fiber by coupling of two individual components neither of which is a dye itself. These two components are on aromatic diezoniem

Dyeing of polyester with disperse dye (HTHT Method)

Theory: Disperse dyes are non-ionic in nature, almost insoluble and stay as finely divided dispersed from in water. It can be hydrolyzed in high temperature especially under alkaline condition. Therefore dyeing with disperse dyes is virtually always done using slightly acedia condition.
