Abstract

The effects of drawing on the structure and physical properties of nylon 6-ran-nylon 4 copolymer filaments were assessed by uniaxially drawing filaments at various ratios at 90 DC and measuring their crystal structure, birefringence, moisture regain, dynamic viscoelasticity, thermal behavior, and tensile properties. X-ray diffraction curves showed sharper peaks with increasing draw ratio. Birefringence and heats of fusion (${\Delta}H_m$) increased with increasing draw ratio, while a slight decrease in moisture regain was observed. The intensity of the $tan{\delta}$ peak decreased and its position shifted towards higher temperatures with increasing draw ratio. Breaking strength increased and breaking elongation decreased with increasing draw ratio.
