This paper reports zeta potential concerning the surface property of the textile fibers that is crucial for dyeing and finishing process. Zeta potential gives a measure of the average charge density at the surface when measured as a function of pH. These interface phenomena influence the adsorption of dyes and finishing agent due to interaction forces between the fiber surface and the solution. A streaming potential method has been used to determine the zeta potential at the surface of the nylon and polyester fibers in supporting electrolyte solution by Electro Kinetic Analyzer. We have investigated the effect of different fibers parameters like denier (fineness) and length on zeta potential. It is found that lower denier (more fineness) and medium length, is the optimum combination for the higher potential of generating surface charge. A comparative study on the Zeta potential of nylon and polyester fibers is also discussed.
