Fiber crimp behavior is an important parameter for processing performance and product quality. In Part I, we quantified the mechanical behavior of a fiber during crimp removal based on load-extension data. A logarithmic function can be used to characterize the shape of the load-extension curve during crimp removal. Characteristic parameters for three different kinds of PET fibers are interpreted in terms of crimp processing settings and correlated with processing performance during carding.
