Abstract:

Aiming to the research on the anisotropy of fabric wrinkle recovery, the relationship between the wrinkle recovery angle and the orientation angle of sample to find out a more reasonable method to evaluate the fabric wrinkle recovery property. The cotton plain and twill fabrics are selected as materials. The specimens of plain fabrics are cut from the orientation angle of 0° to 90°. The twill specimens are cut from the orientation angle of 0° to 180°. The orientation angle of both types of fabrics are in the clockwise direction and at the interval of 15°, and the warp direction is set as 0°. The wrinkle recovery angles are tested by the macine vision method. The result show that the average recovery angle of 15° and 75° orientation angles can be used to assess the property of cotton plain fabric. For the twill fabrics, the property is depended on the twill direction of the fabric. For the left inclined 120° twill fabric, it is suggest that the average recovery angle of 15°, 105° and 120° orientation angle could represent the property of face-to-face folded specimens, and the average recovery angle of 0°, 60° and 120° orientation angle could represent the property of back-to-back ones.
