Fabric bagging is a type of three dimensional permanent deformations of garments that occurs at positions such as elbow and knee. When a prolonged compression force is exerted on a garment during wear, the three dimensional deformation may involve complex inelastic behaviour in the garment, including viscoelastic behaviour of the fibers and plastic behaviour due to frictional movements between fibers and between yarns in the fabric. The aim of this stduy is to engineer extensibilty values of shirt fabrics along weft direction and hence to analyze and interpret the bagging behavior of extensible shirt fabrics in terms of fabric mechanical preoperties. In this study, finished extensible plain woven shirt fabrics with changing the core-spun extensible yarn layout along weft direction were produced. The bagging behavior of samples tested at a speed of 7 (mm/min) and initial bagging height 7(mm) in 5 successive cycles using an Instron tensile tester equipped with 4 circular clamps in 56, 61, 66 and 71 (mm) diameter. The results were then statistically analysed using ANOVA test method. The statistical analysis results show that fabric extensibility along weft direction and sample diameter has a statistical significant effect on bagging behaviour of extensible shirt fabrics. It is indicated with the increase in fabric extensibility and sample diameter the bagging parameters are significantly decreased.
