Paper Title
Likely Mechanism of Dye Adhesion on Fabrics

The mechanism of adhesion of dyes as colouring agents on different types of fabrics is hereby examined. The dyes under study include, basic dyes, acidic dyes, azo dyes, mordant dyes, and vat dyes while the fabrics are cellulosic materials, wool fabrics, nylon 6,6 fabrics, nylon 6 fabrics, silk fabrics and polyester materials. The principle of adhesion proposed leading to the fastness of the colourants is illustrated by the bonding of atoms and molecules arising from intermolecular interactions between functional groups of the dyes and the substrate materials. The functional groups involved are hydroxyl group (-OH), carboxylic group (-COOH), carbonyl group (=C=O), imino group (-NH-) ester group (- COOR), amide group (-CONH2) as well as conjugation in aromatic groups. The types of bonding proposed are ionic, covalent, dative covalent, dipole-dipole forces, and inter molecular hydrogen bonding. The study also shows that adhesion may be enhanced by physical entrapment of the colouring molecules on the substrate. Keywords - adhesion, entrapment, bonding, functional group, fabric and dye
