Abstract

The purpose of this thesis was to study the dye adsorption characteristics of cellulose by means of the Streaming Current Detector. The influence of electrolytes on dye adsorption, and the electrokinetic phenomena of two-sided dyeing were areas of particular concentration.

Contrary to general belief, it was found the addition of sodium chloride was not necessarily beneficial to dye adsorption and in some cases it could actually be detrimental. The Streaming Current Detector was found to be a useful tool for predicting this effect.

The higher charge of fines was found to be an important factor in the increased dye adsorption by fines. Limited control of two sided dyeing could result from further studies relating fiber furnishes and dye materials by means of the Streaming Current Detector.
