Image Analysis for Characterizing Tensile Deformation of Knitted Fabric

Popis výsledku v původním jazyce

Elastic fabrics are considered to be of high importance to produce garments with comfortable fitting to the human body. However, the compression resulting from the tight-fitting of such clothing tends to generate high-pressure and discomfort while wearing them. In order to design comfortable knitted garments, it is necessary to predict their distribution of elastic behavior across different body sizes. The standard tensile testing methods are not sufficient to explain distribution of these elastic properties. When digital image analysis technique is adjusted to the standard tensile test method, more detailed study and additional results can be obtained. This work presented the digital image analysis method for the measurement of local deformations of knitted fabrics during tensile testing. The distributions of elastic properties of fabric under different levels of stretching were determined. The image analysis approach was selected to calculate the gradient deformation tensor under the extension ranging from 10 to 40% in respective course, wale and bias directions. The gradient deformation tensors were obtained by analysis of movements of dots painted on the specimen. In this way, the outcome of this work will help to construct knitted fabric structures with appropriate pressure distribution for comfortable body fitting.
