Notes:
The dielectric behavior of samples of mercerized and hydromercerized cotton was studied in a temperature range of 10-60°C at frequencies of 0.1-10,000 kc/s. The effects of mercerization of medicated cotton and mild hydrolysis of mercerized cotton on the two loss peaks γ and β, found in medicated cotton in this frequency-temperature range, 1 were explored. Mercerization lowers the height of both peaks and, in addition, reveals another β relaxation process in a higher frequency range. Hydrolysis of mercerized cotton removes the γ process, causes variations in the levels of the first β maximum, depending on the time of hydrolysis, and enhances the second β process. These absorption peaks and the effects of various variables are discussed in terms of molecular structure and possible molecular motions responsible for their occurrence.
