Abstract:

Denim is one of the most traditional and fashionable fabrics. The quality of denim fabrics based on their usage is important. The physical and mechanical properties of denim fabrics have considerable influence on their application and comfort . In this study, the effect of the backrest roller position and finishing process on the physical and mechanical properties of denim fabrics was investigated. For this purpose, grey and finished fabrics at five different positions of the backrest roller on a weaving loom were separately produced. Statistical analysis of the results show that in grey fabric, the position of the backrest roller has significant influence on the breaking strength in the warp direction, breaking elongation, warp yarn density, abrasion resistance, tear resistance, air and water permeability, fabric surface colour, and fabric thickness; and it has no significant influence on the breaking strength in the weft direction, weft yarn density, abrasion resistance, and fabric weight. Moreover, no meaningful effect of the back rest roller position on the properties of the finished fabric was observed.
