【Abstract】 The effect of the chemical structure and the micro-phase separation degree of melt-spun polyurethane elastic fibre on mechanical property was studied in this paper. And also effect of spinneret draw-ratio on fibre aggregated structure and the properties was discussed. The results indicated that cross-link is helpful to increasing the stability of hard-segment.更多还原
