Determining Formability Function of Worsted Woven Fabrics in Terms of Fabric Direction

Abstract

Formability is a characteristic which determines fabric behavior during garment manufacturing and wear. It depends on fabric properties such as weave type, fabric density, warp and weft yarn twist, bending rigidity, and fabric tensile behavior, while tolerating small load values. It should be noted that this property changes with fabric direction and is not constant. In this research, fabric formability was investigated for worsted woven fabrics by evaluating this property in various fabric directions. It was concluded that fabric formability could be expressed as a Gaussian function of sample orientation in the warp direction. By studying several weave structures with different weft densities, the effect of firmness on fabric formability was clarified, which lead to better interpretation of fabric adaptability to the applied deformations.
