Seven staple fibers were compared for adhesion to particulate soils.
In this study, spherical particles of hydrated iron (III) oxide (Fe
2O
3·H
2O) were prepared, and adhesion to various fibers of Fe
2O
3·H
2O in the dispersion medium was examined after 48 h under weak mechanical oscillation at various temperatures (15, 30, 50°C).
The amount of soil per unit external surface area of a fiber (g/m
2) was defined as the amount of Fe
2O
3·H
2O adhering to the fiber substrate.
Langmuir type adhesion isotherms were obtained for all staple fibers and were exothermic.
Affinity parameters of the seven fibers in
n-heptane/
n-tetradecane mixtures (95 : 5) were of the following order : Vinylon>Cupra rayon > Polyester > Nylon >Acryl >Poly (vinylchloride) > Polypropylene.
