The dynamic modulus and loss angle of wet keratin fibers have been measured at frequencies between 6 and 1500 Hz in the temperature range 0.2–45°C. Some further measurements were performed at different relative humidities. These results have been compared with other known results, and the agreement or discrepancies found are discussed. A theoretical curve fit has been introduced for a selected set of experimental results.
