Abstract
The effects of various annealing temperatures and durations on the structure and physical properties of polypropylene(PP) slit-film yarns were investigated. Annealing led to a more developed crystal structure, even when the yarns weredrawn before heat treatment. Annealing at 140 oC led to better developed crystal structures than that at 100 oC. Annealing primarilyaffected the crystalline structure, whereas little change was observed in the molecular orientation of the yarns. The slitfilmyarns annealed at 140 oC showed less than 1% shrinkage. A very low-shrinkage slit-film yarn was obtained on annealingfor 10 min at 140 oC or 20 min at 100 oC.
