Effect of interlacement frequency on the single and multiple yarn end pull-out properties of woven fabrics

In this study, the pull-out properties of plain, ribs, and satin fabric weaves were examined. Data generated from these tests included pull-out force, crimp extension, and fabric displacement. It was found that yarn pull-out forces depend on fabric density, fabric weave, fabric sample dimensions, and the number of pulled ends in the fabric. Results showed that 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. Plain weave had high single and multiple pull-out forces compared with those of ribs and satin weaves. Long fabric samples showed high single and multiple pull-out forces compared with those of short fabric samples. The yarn crimp extension depends on the directional crimp ratios in the fabric, fabric sample dimensions, and the number of pulled yarn ends. Directional high crimp ratio fabric showed high directional yarn crimp extension. Fabric displacement depends on the fabric sample dimensions and the number of pulled yarn ends. Long fabric samples showed high fabric displacement. In addition, fabric displacement in multiple pull-out tests showed high fabric displacement compared with that of single pull-out tests.
