Abstract
Since the woven fabric is used on the 3D body, it encounters bending deformation and crease in various directions. Due to the prominence of these deformations in the appearance of the garment, the inspection of bending and crease recovery behaviour of fabric in different directions needs to be considered. In this paper, the evaluation of bending rigidity and crease recovery of fabrics is carried out in various directions. Analysis of the results revealed that fabric-bending rigidity could be expressed as a sinusoidal function of sample orientation towards warp direction. For all the studied fabrics, from warp axis to bias direction, bending rigidity follows a descending trend, however; crease recovery angle has an ascending tendency. Reverse variations were achieved for both properties from bias direction to weft axis due to the variant warp and weft yarn contributions in each direction. Hence, the lowest bending rigidity was obtained in the bias direction (45°), while the highest crease recovery angle was recorded for the mentioned direction. Moreover, an exponential function is utilized to express the non-linear relation between bending rigidity and the crease recovery in different directions of the fabric. The statistical analysis of the results clarified that the effect of fabric direction and structural parameters on the bending and crease recovery behaviour is significant in the confidence range of 95%.
