Abstract
A study was made of the transfer of compounds, similar to those found in human sebum, from cellulose to polyethylene terephthalate films and the deposition of these soils on polymer films from surfactant and aqueous solutions. The polymer films were used as end windows of a Geiger tube. The soils were labeled with radioactive 14carbon so that the amount of sorbed material could be continuously monitored. The effect of variables such as detergent type, detergent concentration, temperature, sorption time, addition of sodium carboxymethylcellulose, and soil concentration on deposition have been investigated. Results are discussed in terms of possible mechanisms for soil depo sition and changes in wash conditions that should reduce deposition on man-made polymers.
