Abstract
Injected slub yarn is one of the most promising among different types of slub yarns. Present study embodies the effect of some important parameters like base yarn twist level, number of base yarn, twist direction and injected fibre components on injected slub yarn performance in terms of tensile strength and breaking elongation. In case of single base slub yarn, final yarn tenacity and elongation increases with the reduction of base yarn twist level keeping final yarn twist multiplier constant. However, the effect of base yarn twist level is marginal in case of injected slub yarn made with double base yarn. Yarn tenacity and elongation significantly higher in case of double base injected yarns as compared to single base injected yarn. The aforementioned tensile parameters of single base injected slub yarns reduce with the reduction of yarn linear density. However, in case of double base injected slub yarns, highest tenacity and elongation value are achieved for 2/80s yarn having finest yarn liner density among 2/40s, 2/60s and 2/80s yarns. In case of single base injected slub yarn, tensile strength is slightly higher and elongation values are significantly higher when injection component fibres changed from 100 % cotton to 50/50 polyester/cotton blended fibres which is just opposite to that of double base injected slub yarn. Results also showed that the twist direction in the base and final yarn influence the strength and elongation of injected slub yarns.
