The stress-induced crystallization influences the ability to sustain the stress of deformation occurring in the spin line. Optical micrographs of fluffs allow the assumption of different deformation or stress behavior of core and skin layers of spun fibers, as shown in Figure 13.1. The reason for this kind of yam break can...

Fig. 16 Series of interference contrast optical micrographs of an initially 4.2 wt % solution of n-Ci98H398 in phenyldecane at successive times (indicated) upon reaching Tc = 97.4 °C. The progress of the dilution wave is shown in (b) through (f), triggering the processes of crystallization of needle-like extended-chain crystals and simultaneous dissolution of folded-chain crystals. The needles form along the two 100 faces of the truncated lozenge shaped folded-chain crystals, with a third parallel crystal often appearing in the middle. Bar = 20 pm.
