Soiling and desoiling properties of particulate soil (Fe_2O_3・H_2O) to polyester staple fibers in the binary solvents of petroleum and various alcohols have been investigated in an incubator with weak mechanical oscillation at 20℃. The main results obtained are summarized as follows : 1) In the single solvent system, the degree of removal of Fe_2O_3・H_2O decreased in the order of ethyl alcohol > tetrachloroethylene > n-undecane > n-heptane > n-hexane. 2) In the binary solvent system (n-heptane/ethyl alcohol or n-undecane/n-octyl alcohol), the degree of removal of Fe_2O_3・H_2O increased remarkably with a ca. 5% alcohol content and similar results were obtained with the addition of surfactant (Aerosol OT) to petroleum solvent. Therefore, it was suggested to save added surfactant in non-aqueous cleaning with petroleum/alcohol binary solvents. 3) Soiling properties were affected by the component of solvent and the deposition of Fe_2O_3・H_2O on polyester fiber decreased with a ca. 5% alcohol content in the solvent. 4) In the binary solvents of n-undecane and various alcohols, the deposition of Fe_2O_3・H_2O decreased in the order of ethyl alcohol > n-propyl alcohol > n-butyl alcohol > n-octyl alcohol.
