Abstract :Denim is fabric construction which is popular worldwide with its fit, ease and durability and it has evolved significantly in terms of aesthetic and functional properties throughout time to maintain this popularity. Denim fabric manufacturers are in search of different visual and functional properties at all times. In this study, dual-core slub yarns were developed for using as weft yarn in denim fabric structure. Dual-core and slub production techniques were used simultaneously for production of dual-core slub yarns which will use improving elastic and aesthetic properties of denim fabrics. Within the scope of the study, firstly dual-core slub yarn samples called Group-I were produced with different core draft values of EME ( Elastomultiester-I.core) and elastane (II.core). The effects of cores’ draft on the properties of dual-core slub yarns such as unevenness, hairiness, tenacity and breaking elongation were investigated with Group-I yarn samples.  The breaking elongation values are affected by both EME and elastane core draft factors, while the tenacity is only affected by EME core draft factor. Moreover, in order to examine the effects of slub types, the physical properties of one of the dual-core slub yarn selected from Group I, were compared with equivalent dual-core yarns (having two different version of basic slub and without slub) which called Group II. The results showed that slub types have statistically significant effect on the only unevenness values.
