This research was conducted with the technical production of nanofiber electrolyte Spinning taste of casein is mixed with polyvinyl chloride. By studying the ratios suitable for forming a nanofiber, Viscosity and Scanning electron microscope (SEM) by the SEM found that fibers from the process electrolyte taste Spinning size and evenness of the fiber is not uniform. The amount Beast (Beads), and the solution, which caused a chain molecule Entanglement is not enough and solvent evaporates quickly, while forming and studies forming the 50 and 75 percent of casein by. proper weight to form a nano fiber by solution began to plunge. Toward the substrate and jet aircraft, but also caused a clear drop of liquid at the surface between the bracket and the pin because the viscosity of the solution was not enough.
