Abstract
Commercially available polypropylene fiber (PPF) samples with relaxation heat setting for 30 minutes in a drying oven at various temperatures (room temperature, 90 °C, 100 °C, 110 °C, 120 °C, 130 °C, 140 °C, 150 °C, respectively.) were prepared for measurement of their sonic velocity, orientation degree, orientation angle and modulus. According to the obtained data for the PPF molecular orientation before and after the relaxation heat setting, it is found that, with the increasing of relaxation heat setting temperature, the sonic velocity in PPF, orientation degree and modulus decreased, while the orientation angle increased. The result may be helpful to choose proper working temperature for PP hernia patch fabrication.
