Abstract

Electro-osmotic (or electrokinetic) transport is used to efficiently force a solution (or water) through the interior of the fibers or yarns of textile materials for wet processing of textiles. The textile material is passed between electrodes that apply an electric field across the fabric. Used alone or in parallel with conventional hydraulic washing (forced convection), electro-osmotic transport greatly reduces the amount of water used in wet processing. The amount of water required to achieve a fixed level of rinsing of tint can be reduced, for example, to 1--5 lbs water per pound of fabric from an industry benchmark of 20 lbs water/lb fabric. 5 figs.

Technical Report Cooper, John; McCreight, Dan

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 ofmore »« less

Applications of Electro-Osmotic Transport in the Processing of Textiles

Conference Cooper, J; Krueger, R; Hopper, R; ...

We report development of a pilot process for the industrial rinsing of fabrics. This process combines hydraulic (pressure-driven) transport with electro-osmotic transport. It reduces the total amount of water required in certain rinsing operations by a factor of about five. Cotton exhibits an electro-osmotic transport coefficient of about 6 x 10{sup -9} m{sup 2}/s-V resulting from a partial ionization of hydroxyl groups on the cellulose polymer substrate. This process applies a field transverse to the fabric to effect the movement of water in the spaces between the 10 {micro}m cotton fibers which constitute the yam. The field strength is adjustedmore »« less

Application of ultrasound in textile wet processing, Phase 1

Technical Report Smith, C

The US textile industry urgently needs new technologies to keep the industry competitive. This study was designed to develop a pilot plant-scale ultrasonic continuous yarn-dyeing system and to establish a foundation for continuing research in the use of ultrasonic energy in textile processes. On the basis of their findings in the literature on ultrasound-enhanced textile wet processing, researchers designed laboratory- and pilot-scale equipment and conducted studies using various dye and fiber combinations. In laboratory studies they used small vessels of approximately 1-liter capacity and ultrasound probes of 400--1200 W output. Pilot studies were conducted in a 40-gallon dye tank usingmore »« less
