Approximation of Sorption Isotherms of Fiber Materials by Various Equations

详细

The sorption-structural properties of fibers, fabrics, and nonwovens are analyzed and the possibility of describing isotherms of water vapor sorption by various equations is examined. It is shown that for approximation of sorption isotherms of various fiber materials use of Zimmerman’s equation for capillary-porous materials in most appropriate. This equation is recommended for use in calculations of drying, extraction, soaking, and other processes of thermohygric treatment of fiber materials.
