WebMany plastic polymers and fibers have some order and can be identified and studied by X-ray diffraction methods. These polymers are, at least in part, crystalline or pseudo-crystalline with partially ordered structures which cause diffraction peaks. In fact, the percent crystallinity in a polymer can be determined by X-ray diffraction methods ... WebSome most common fibers such as polyethylene terephthalate, nylon 6, nylon 66, polypropylene, and polyether ether ketone are spun by melt-spinning process. Melt-spinning is a superior fiber manufacturing technique for high-performance fibers as well. Select Chapter 3 - Spin finish for natural and synthetic fibers.
