Application of Image Analysis Method for Measurement of Fabric Stretch Deformation

Popis výsledku v původním jazyce

For design of comfortable knitted fabric garments, it is necessary to know their distribution of elastic properties under the deformation. The standard tensile testing methods are not sufficient to explain distribution of these stretch properties. However, digital image analysis technique adjusted to the standard tensile test method can perform detailed study on distribution of local elastic deformation properties. The aim of this research was to develop a new method for the measurement of the local deformations between dots of stretch knitted fabrics during tensile testing. The image analysis approach was selected to calculate the gradient deformation tensor under the extension ranging from 10 %, 20%, 30% and 40 % in respective course, wale and bias directions. Moreover, this method was applied to know the deformation distribution on cylindrical surface as well by stretching the fabric under different extension. Subsequently the analysis of the deformation distribution by image processing system in MATLAB was carried out to determine the compression between cylindrical model and specimens. The results of image analysis were compared with ASTM D4964-96 standard and the actual obtained experimental results.
