The Influence of Heat Setting on Polypropylene Woven Filter Cloth
In order to study the change of the filter cloth and the change of supramolecular structure after heat setting, two groups of filtering cloths were produced using polypropylene monofilament, Scanning electron microscope, IR Spectrometer FTIR and differential scanning calorimeter were used to observe the structure variation before and after heat setting. It was found that the fabrics in different groups exhibited significantly different surface structures, after heat setting. In addition, the infrared spectrogram and DSC data revealed that supramolecular structure of polypropylene fiber did not change after heat setting, since no new chemical bond was observed after heat setting.
