Abstract:

Aiming at the actuality that for the measurement of the fabric bending behavior, more than one fabric samples are needed to obtain more than one test result, a simple and fabric saving bowknot method for testing the bending behavior of wool fabric was proposed, and the detailed method and parameters of area, width, height and angle of bowknot were elaborated. 18 kinds of wool fabrics were used to compare the new method with the conventional method. The results show that the correlations between the four indexes in the new method and bending rigidity are good. The bowknots of stiffer wool fabrics will have larger angle, width and area, but smaller height. The area of the bowknot has the highest correlation with the bending rigidity. Moreover, the regression equation between the area bowknot and the bending rigidity is established for the predicting the fabric bending rigidity.

Key words: wool fabric, bending behavior, bending rigidity, bowknot method
