Iodine adsorption experiment was carried out and the following results have been obtained.
In a series of experiments at the different iodinepotassium iodide ratio from 1: 1 to 1: 8, little change has been observed for the adsorption capacity. But in the case of polyvinyl formal, it became smaller as the ratio was decreased.
Except at high concentration, Freundlich'e equation was applicable. The heat of adsorption was obserbed considerably small. Iodine adsorption capacity of the filaments, which were treated at different temperatures, was also measured while the experiments of the water adsorption were carried out with the same samples.
The iodine adsorption values may be considered as a measure for the amorphous parts.
Several other iodine adsorption experiments were also carried out with other fibers; among which 6-Nylon and acetate rayon have shown large adsorption values.
Generally, no definite relation is detected between iodine adsorption and the water adsorption values.
