摘要
利用数字图像技术获得非织造布表面形态的二值图像,根据分形理论用S ierp insk i地毯法求得孔隙的面积分形维数Df;用计算机模拟纵向毛细管通道,并用计盒法求得弯曲分形维数DT。孔隙分形维数的求解为研究非织造布的结构和性能提供了有效而可靠的方法。
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.
