| Abstract: | To investigate the effect of fibre cross-sectional shape on hand of polyethylene terephthalate continuous multifilament fabrics, different fabric samples are developed with similar fabric areal density, weave, yarn and fibre linear density. The effect of fibre cross-sectional shape on various structure–property relationship of fabric is precisely characterized. Different cross-sectional shapes have different stiffness as well as different packing index with ideal geometry of filament yarns. The low-stress mechanical properties and hand behaviour of fabric are also altered by change in cross-sectional shape of filaments. The experimental results indicate that the alteration in cross-sectional shape can be a powerful tool for fabric engineering. |
