This project was undertaken to develop and demonstrate on a pilot scale the use of electro-osmotic transport to increase the efficiency of textiles wet processing operations. In particular, we sought to develop a means of rinsing textiles to remove material entrapped between the individual fibers that constitute a yarn. Material trapped within the yarn is slow to exchange with rinse water flowing primarily in the open weave are abetween the yarns. The application of an external field (strength, 5-50 kV /m) requires only a few volts for most fabric thicknesses. This field is sufficient to promote a rapid exchange of material to enhance rinsing and reduce the water required for rinsing from about 20 kg/kg-fabric to 3-6 kg/kg-fabric. We successfully developed technical and economic models of application of the process to the rinsing of many materials of industrial importance, including dyes, tints, chemicals, detergents and dye electrolytes. We demonstrated the process on a pilot plant scale using a translator designed in cooperation with Milliken and Company (Spartanburg, SC).
