Abstract

The stress-relaxation behaviour of uniaxially drawn nylon 6 films was studied under with various crystallinty and varous initial strain at temperature range from 248K or 298K. In case of the same crystallinity, the change of stress-relaxation moduli of small strain was faster than that large. The absolute value of stress-relaxation modulus increased with the increase of crystallinity and the slope of stress-relaxation curves of small crystallinity was faster than that of large. The apparent activation energy of stress-relaxation increased with the increase of crystallinity.
