Abstract
It is obvious that estimation of the effective surface area is essential to evaluate the soiling properties of fabrics.
In this paper, equilibrium deposition of soils on the 5 different kinds of polyester taffeta with different filament diameter has been determined by chemical analysis of adhered Fe2O3·H2O spherical particles on the fabric surface.
After saturation in the Fe2O3·H2O /CCl4 suspension, the amount of soils on the filaments and fabrics were extracted for analysis, and the packed monolayer particle distribution on the filaments as well as on the fabrics surface was proved by the scanning electron micrograph.
Comparing the number of adhered Fe2O3·H2O particles (1.3, 2.0 and 4.5μm respectively) to the filaments and fabrics, the effective surface area of the fabric was estimated.
In the case of the filament, the number of adhered particles per unit surface area (N) and particle size (d) were linearly plotted in the following equation irrespective of the filament diameter :
logN=-nlogd+logk
In the case of the fabrics, the same relationship was obtained as to the number of adhered particles per unit weight.
These results may suggest a clue to find a reasonable approach to determine the effective surface area of the fabrics.
