| Abstract: | The test equipment of wool fiber crimp is designed . The test method of two - dimensional crimp by image analysis is studied. It is suggested that the radius of curvature of crimp is used to characterize quantitatively the crimp morphology. Chebysher curve fitting is used to structure the mathematical model of wool fiber crimp. The differences of the radius of curvature of crimp at different measurements are studied. The effect of measurement on test results is analyzed. The experiment indicates that this technique is proved useful in the general application of crimp characterization and classification . |
