Orientation and structural changes upon uni- and biaxial drawing of polyamide 6 — •Hussein Shanak1, Karl-Heinz Ehses1, Jan Lion1, Peter Leibenguth2, and Rolf Pelster1 — 1FR 7.2, Experimentalphysik, Universität des Saarlandes, Postfach 151150, 66041 Saarbrücken — 2Lehrstuhl für Funktionswerkstoffe, Universität des Saarlandes, Postfach 151150, 66041 Saarbrücken, Germany
The influence of drawing on orientation, crystallinity, structural properties and anisotropy of polyamide 6 films was investigated. The samples were uniaxially and biaxially stretched. Their crystallinity as well as size and orientation of the crystallites were evaluated using X-ray diffraction. The orientation was analyzed using pole figures and hermans functions. In case of uniaxial drawing, the crystallinity increases and the films show strong orientation with increasing drawing ratio. The orientation of the biaxially drawn films is high and it is inhomogeneous, depending on the position on the film. The structural data is correlated with dielectric anisotropy that was measured at microwave frequencies.
