Effect of Ultrasound on the Dry Heat Behaviors of Cattlehide Collagen Fibers

In this paper, the dry heat behaviors of different cattlehide collagen fiber samples with and without power ultrasound process are studied, and such instruments as Thermal Platform Microscope, Differential Scanning Calorimetry (DSC) and Thermogravimetry (TG) are employed in the study. It is indicated that the dry heat behavior of the samples is slightly decreased because of the power ultrasound process. The reason why it is the case may be that part of the crystalline structure in the samples is destroyed by the power ultrasound process.
