Studies on Application of Chemical Modified Epoxy Resin as A Coupling Agent in Polymeric Azo Dyes

Comparative study and dyeing performance of as-synthesized azo heterocyclic monomeric, polymeric, and commercial disperse dyes

“…The marriage of polymer and dye chemistry enables the chemist to design unique materials that exploit the best characteristics of both pigments and dyes [ 3 ]. The synthetic dyes play the major role in textile fiber fashioning [ 4 ], specialty materials having several advantages over their monomeric dyes counterparts, consequently in the last few decades; they have been documented well by many research scientists [ 4 ]. They have been widely applied on fiber because of certain essential dye properties such as fast leveling, fastness to light and wet treatment, low sublimation rate, and very good thermal and chemical resistance [ 5 ].…”

“…Polymeric dyes have excellent brightness and extremely fadeless [ 7 ]. Colorants, which include chromophores of dyes usually consisting of C=C, N=N, C=N, attached to aromatic or heterocyclic rings, containing oxygen, nitrogen or sulfur, have been widely used as dyes owing to their versatility in various fields and high technology, including textiles, paper, leather, plastics, biological staining, lasers, liquid crystalline displays, ink-jet printers, and in specialized applications, such as food, drug, cosmetic and photochemical productions [ 4 , 5 ]. Dyes are classified based on their chromophoric groups or method of application unto the substrate.…”
