Abstract

The sorption properties of thermostable fibers are essentially a function of the method of sample preparation. Drying them at a high temperature significantly decreases the sorption properties due to a decrease in the pore space volume. Preliminary drying of the samples at 20°C with evacuation over a desiccant is recommended for an accurate evaluation of the sorption properties of thermostable fibers. The preliminary effect of moisture and subsequent drying alter the structure of SVM fibers, causing a decrease in sorption with low atmospheric humidity and an increase in sorption and hysteresis with high humidity.
