Chemistry And Technology Of Man-Made Fibres


A rapid method has been worked out for measuring the degree of crystallinity of fibrous materials, which is based on a linear dependence of this quantity on the integral heat of sorption.

It has been suggested to carry out practical calculations within the framework of the theoretical probability model of sorption, which permits one to calculate the integral heat of sorption from a minimum amount of experimental material, or attended with calorimetric measurements.

Sorption constants and integral heats of water sorption have been given for a large set of hydrocellulose and polyamide fibres.
