The aim of this study was to understand the effects of softening treatment on pull-out properties of plain, ribs and satin fabrics. Polyester woven fabrics were used to conduct the pull-out tests. Data generated from these tests included pull-out force, crimp extension and fabric displacement. A developed yarn pull-out fixture was used to perform single and multiple pull-out tests on treated and untreated polyester fabrics. Yarn pull-out forces depend on fabric treatments, fabric density, fabric weave, and the number of pulled ends in the fabric. The results of regression model showed that multiple and single yarn pull-out forces of treated fabrics were lower than those of untreated fabrics. The multiple yarn pull-out force was higher than that of the single yarn pull-out force, and that dense fabric had a high pull-out force. Treated and untreated plain fabrics had high single and multiple pull-out forces compared to those of treated and untreated ribs and satin fabrics. Yarn crimp extension depends on directional crimp ratios in the fabric and the number of pulled yarn ends. High directional crimp ratio fabric showed high directional yarn crimp extension. Fabric displacement depends on the number of pulled yarn ends and also fabric treatments. Fabric displacement in multiple pull-out tests showed high fabric displacement compared to that of single pull-out tests. On the other hand, the regression model could be used in this study as a viable and reliable tool.
