Abstract:
In injected slub yarn, tensile and abrasion resistance are particularly very important parameters affecting its process performance and end-use. In single base injected slub yarn structure, slubs are developed by injecting fibres from outer side of the yarn with the sequence of untwisting base yarn followed by re-twisting after injecting the fibres. The tensile properties and abrasion resistance of injected slub yarns depend on the slub parameters. The surface of the yarn, especially the slub part is very much susceptible to damage by abrasion during usage, due to lack of fibre migration between base yarn fibres and injected fibres. In this paper, an attempt has been made to see the impact of slub yarn configuration i.e. slub length, slub thickness and slub frequency on tensile and abrasion resistance of injected slub yarn. Empirical models have been developed to find the dependence of these properties on slub yarn configurations. Configuration of slubs in particular slub length and slub frequency were found to be very significant on yarn tenacity, elongation and abrasion damage in terms of tenacity loss, elongation loss and hairiness rise of injected slub yarn. However, the impact of slub thickness is relatively less on the aforesaid parameters.
