COMPARATIVE STUDY ON THE DYEABILITY OF COTTON, SILK AND POLYESTER FABRICS BY CONVENTIONAL AND ELECTROCHEMICAL METHODS

摘要

Cyclic Voltammetric experiments were carried out for the five different classes of dyes to understand the redox behavior (anodic oxidation / cathodic reduction). The redox property of dyes in relation to the dyeability was studied. The dyes selected were of anionic in nature. In the electrochemical method, the fabric was embedded on the anode and potential was applied for coloration purpose. The dyeability results revealed that the depth of shade was independent of the fabric substrate. The color strength (K/S) was measured by Computer color matching machine and the results were compared between the samples colored by both conventional and embedded systems. The uptake of dye onto the fabric increased with increase in applied potential
