Abstract: Parafil Yarns using jute as core and polyester, nylon and HDPE as wrapper filaments have been prepared using a six-spindle Suessen Parafil-2000 parallel yarn spinning machine and the influence of wrapping material and wraps/m on yarn properties has been studied. It is observed that the mechanical properties of parafil yarns are greatly influenced by the packing density of the yarn, which, in turn, is influenced by both wraps/m and type of wrapping filament used. There is a good correlation between packing coefficient and breaking energy of the wrapped yarn. Heat-setting of wrapped yarn under constant length condition improves the breaking energy of yarns by more than 20%.
