| Abstract: | The binary image of nonwovens surface morphology can be obtained by digital image technology.The pore area fractal dimension Df is determined by Sierpinski-basket method based on fractal theory.Computer simulating tortuous capillary tube was developed,whose tortuosity fractal dimension DT is determined by box-counting method.It is an effective and reliable method to study the structure and properties of nonwovens. |
